Part II
Price setting and regulation
Chapter 3
Price setting and key causes of electricity price increases
3.1
This chapter provides a brief summary of how electricity prices are set
and outlines a collection of the wide range of factors contributing to
electricity price rises that have been put to the committee. At the end of the
chapter, the committee draws some conclusions about factors contributing to
electricity prices increases. The following chapter covers some of the more
serious reasons arising from regulatory arrangements in more detail.
Price setting
3.2
There is a mixture of market and regulated price outcomes across the
wholesale, transmission and distribution networks and retail parts of the Australian
electricity sector.
3.3
Wholesale prices paid to electricity generators are a result of the
National Electricity Market (NEM) which provides a highly competitive, computerised
wholesale market on the east coast of Australia. All energy generators go into
a pool and retailers bid. There are five interconnected trading regions that
align closely with state boundaries.[1]
Separate arrangements exist for Western Australia and the Northern Territory
(see Chapter 2).
3.4
There is base pricing and spot pricing. The base pricing tends to
reflect the long run cost of coal based electricity generation under quiet and
stable market conditions. Prices can separate in different regions depending on
demand variations across regions. Temperature fluctuations can lead to
significant surges in peak demand, which can lead to large spikes in the spot
prices which are the settlement prices for the electricity at particular points
in time. Retailers use separate contracts including options and hedging to
manage risks arising from spikes in spot prices.[2]
3.5
The pricing of electricity transmission and distribution network
services is regulated due to the natural monopoly that exists in most cases.
The Australian Energy Regulator (AER) makes determinations on the value of
regulated asset bases and the rate of return allowed, based on the demand and
investment forecasts provided to them by network businesses.[3]
3.6
Demand and investment forecasts for electricity networks are based in
part on reliability standards set by the state regulators. Network assets are
very long-life assets and the consequences of under-building assets can be
catastrophic. Consumers value reliability very highly, but may not wish to pay
for this.
3.7
Some concerns have been raised that current regulatory arrangements have
made it too easy for electricity network owners to over invest and take
increased profits from guaranteed revenue streams.[4]
In contrast, there is a genuine need to replace ageing infrastructure and the
costs of capital required to make the investments have increased since the
global financial crisis.[5]
Further information on what investment has been occurring is available from the
AER and the Energy Networks Association (ENA).[6]
3.8
The relevant state or territory regulator sets price caps in New South
Wales (NSW), Victoria and South Australia and revenue per customer caps in
Queensland, Tasmania and the Australian Capital Territory (ACT). Network
service providers (NSPs) recover their price or revenue cap by passing that on
to retailers and thereby onto consumers.
3.9
Electricity retailers must pay both the wholesale price and network
charges for electricity and therefore pass those onto consumers, along with
retail charges and costs as approved by different regulators in states and
territories. Victoria is an exception as it has deregulated its retail
electricity market and prices.[7]
Comparison to other sectors
3.10
Electricity is not alone: prices have also risen for other utilities as
shown in Figure 3.1. The rise in gas, water and sewerage prices has been
similar to the rise in electricity prices.
Figure 3.1: Utilities price
inflation[8]

Key causes of electricity price increases
3.11
A wide range of possible causes for electricity prices have been raised.
In this section, the committee is mainly focussing on residential prices,
however, business prices are mentioned briefly in relation to the separate
business and retail prices. Professor Ross Garnaut informed the committee that:
In my view, there was no good public policy reason for this
large increase in prices. It happened because of the way we chose to regulate
prices. Contributions to the price increases were made across transmission,
distribution and retail. Generation has not been contributing much to the
increases. Indeed, if you include electricity prices at a wholesale level—that
is, out of the generators, including the carbon price—they are lower in real
terms in October 2012 than in 2006-07. So the huge increases in electricity
prices in Australia over the past half-dozen years are the result of what has
happened in pricing of transmission, distribution and retail margins.[9]
3.12
The contributions to electricity prices vary across different parts of
the electricity supply system, as shown in Figure 3.2.
Figure 3.2: Components of an
average Australian household electricity bill in 2012–13[10]

3.13
The Australian Energy Market Commission (AEMC) has estimated that nationally,
residential electricity prices are projected to increase by 37 per cent in
nominal terms. In real terms, this is an increase of 22 per cent. The
contributions to future price increases across components of the electricity
industry are estimated to be:[11]
Transmission
|
6.0 per cent
|
Distribution
|
33.6 per cent
|
Wholesale
|
40.2 per cent
|
Retail
|
12.1 per cent
|
Carbon Tax
|
5.7 per cent
|
Feed-in tariff
|
2.8 per cent
|
Large-scale Renewable Energy Target (LRET)[12]
|
3.8 per cent
|
Small-sale Renewable Energy Scheme (SRES)[13]
|
-0.8 per cent
|
Other state based schemes
|
2.3 per cent
|
3.14
In addition to their own usage levels, the electricity price increases
incurred by consumers are also influenced by factors including electricity
markets and market power, business and investment issues, technical and
reliability requirements, and policy and regulatory settings. The discussion in
the rest of this chapter covers some of the possible causes of electricity
price rises that have been raised with the committee and are grouped in Figure
3.3.
Figure 3.3: Possible contribution
to electricity prices

Markets
and market power
3.15
The committee was informed of a range of market and market power factors
that may contribute to electricity prices, including demand, demand forecasts,
an investment surge, changes in peak demand, wholesale prices, lack of retail
competition, cross-ownership, hedging, billing and marketing. The following
sections briefly summarise each of those potential contributions to electricity
prices across the generation, transmission, distribution and retail components
of the electricity industry.
3.16
Where there is sustained abuse of market power, the regulator has some
powers to step in, in some circumstances, but generally the regulator must act
by taking the relevant companies to court.[14]
Investment surge
3.17
The surge in investment in the electricity industry is coinciding with
the well-known surge in business investment across the economy more generally.
Similarly in the late 1970s and early 1980s the surge in investment in the
electricity industry coincided with the more general surge in investment that
also occurred at that time.[15]
Professor Stuart White elaborated:
This has been a big issue in network assets. We tend to have
cycles of significant network investment and then cycles where we see less.[16]
Demand and demand forecasts
3.18
The National Generators Forum (NGF) informed the committee that in
recent years overall demand for electricity has been falling:
[O]ver the past five years, electricity demand across the
national electricity market has been declining. It has declined by around 3½
per cent over that time frame. That is due to a range of reasons—notably, the
increase in the retail price of electricity; declining industrial demand;
reduced manufacturing activity; energy efficiency initiatives; and solar PV
systems.[17]
3.19
Noting that demand forecasts are central to price and revenue caps in
the regulated parts of the industry, concerns have been raised about the
regulatory decisions that have been based on forecasts of rising demand, given
that demand is actually falling. The AER noted its approach to considering
demand forecasts provided by electricity businesses:
We do receive demand forecasts from the business. We
challenge those. I think it would be unusual for us to accept the demand
forecasts that have been put in front of us, and there have been a range of
reasons for that. So that power currently exists, and we would continue to examine
those demand forecasts and also to look to external advice for confirmation of
an appropriate demand forecast.[18]
3.20
The AER also pointed out the forecasts for peak and aggregate demand
have different impacts of electricity prices:
We probably ought to recognise that there are two categories
of demand forecast, and it is important to recognise the distinction. One is
peak demand, and it is peak demand that drives investment. The other is
aggregate demand, and aggregate demand is important for recovering costs,
because you recover over the total demand, and that determines prices.[19]
3.21
Energex explained to the committee how the falling demand in recent
years had impacted electricity prices.
More recently, deteriorating network utilisation as total
energy consumption has moderated is forcing up network prices as the costs of
providing, operating and maintaining the network are spread over a lower
consumption base whilst maximum demand remains at record levels.[20]
Peak demand
3.22
The committee noted information suggesting that peak demand has
increased due to a greater deployment and use of air conditioners and other
appliances in recent years requiring more transmission and distribution
capacity that is only used a small fraction of the time.[21]
The Productivity Commission noted that 'some 25 per cent of retail electricity
bills are required to meet around 40 hours of critical peak
demand each year'.[22]
The problems of peak demand were echoed by the Alternative Technology
Association (ATA):
The current state of rising electricity prices is primarily
driven by a failure to manage peak demand, both at a network and a generation
level. The inability or reluctance to properly engage the demand side of the
market has led to over investment in and inefficient operation of the electricity
system as a whole.[23]
3.23
Other submitters and witnesses stated '[p]eak demand is a real issue'[24]
and:
Our key messages are that network costs and costs of peak
demand are the single biggest drivers of rising electricity prices—we recognise
that—and that energy consumers, from our point of view, and business consumers
want reform.[25]
[Another] driver is the cost of supplying power for what we
call peak demand, which is those five to 10 days a year. On the mainland of
Australia they are the hot days; the summer peaks are the clear peaks. Around
20 to 25 per cent of the generation and transmission infrastructure is designed
to supply power for those peak days. Bringing those peaks down is a critical
opportunity to reduce the cost of energy to households and businesses in
Australia.[26]
Peak demand has surged in recent times with the dramatic
growth in air conditioning load driving network companies to invest for the
short summer peak...[27]
3.24
While investment in networks to support peak demand is a glaring issue,
the committee was informed that some care is needed in assessing the impact of
both generation and network investment as indicated by Grid Australia:
It is possible you could increase generation capacity by 25
per cent and have no transmission increase if that generation is located at
points where there is spare capacity in the network. If somebody wants to make
a development and pay for a development that is, for example, remote or where
there is limited capacity and you need to increase it, then that may drive
costs. It really depends on where the generation connects and what sort of
capacity there is at any point in the network. It is quite a complex answer.[28]
3.25
Another impact of peak demand is the need for generation systems that
can switch on quickly and be available to meet rapidly rising demand on a given
day, however a downside is that those systems may then be idle and not directly
earning a return for significant periods:
While difficult to quantify with precision, the increase in
peak to average demand between 1997 and 2010 is estimated to have required an
additional 6 300 MW of (peak) generation capacity, compared with what would
otherwise have been the case...The additional peaking capacity represents around
13 per cent of current generation capacity, and while it is critical in terms
of meeting peak summer demand during extremely hot periods, it sits idle for
the majority of the year. (It represents an investment of around $6.2 billion,
which is around 6 per cent of total capital investment in Electricity supply
over the period.) [29]
3.26
The committee also heard a different point of view, suggesting that peak
demand is not increasing and that demand forecasts predicting an increase are
inaccurate.[30]
Data from the AER indicates that over the last four years (that is, since
2008–09) the level of peak demand is flat or falling for bother summer and
winter in states serviced by the NEM.[31]
Wholesale prices
3.27
Changes in wholesale prices were raised with the committee on a number
of occasions. Much of the evidence presented to the committee suggested there
had been some downward pressure on wholesale prices, as the following example
indicates.
[W]holesale electricity prices in the national electricity
market over the past 14 years. It shows the nominal electricity price. What you
can see is that the price has remained almost constant over that period of
time. There was a period during 2008 when, principally due to the drought and
the hot weather conditions, the prices increased. But, generally speaking,
prices have been very flat and stable. Today the prices are around 50 per cent
lower than what they were in the mid to late 1990s when electricity generation
was owned and operated by state governments. I should say that that excludes
the impact of the carbon price.[32]
3.28
It has been suggested that some electricity generators may be able to withhold
electricity supply capacity in order to have a material impact on price.[33]
Professor Alan Pears AM cited some other information:
There has been evidence over many years that some generators
have "gamed" the system by limiting generation capacity at times, to
push up prices. ABARE (2002), drew attention to this and estimated the cost to
the economy of this practice at between $81 and $412 million per annum. Recently
media reports have raised more alleged examples...The structure of the market, in
which all bidders on the spot market are paid the price bid by the highest
successful bidder, creates an incentive to "game".[34]
3.29
This issue has created sufficient concern among some stakeholders that a
formal rule change through the Australian Energy Market Commission (AEMC) has
been sought by the Major Energy Users Inc (MEU). The rule change request seeks
to constrain the perceived exercise of market power by generators in the NEM.
The MEU's concerns included:
The MEU considers that during periods of high demand when the
system is operating normally, some large generators do not face effective
competition and have the ability and incentive to use market power to increase
the wholesale electricity spot price.[35]
3.30
In its draft determination, the AEMC concluded that:
Based on the AEMC's analysis, consultant analysis and
stakeholder feedback to the consultation paper, directions paper, public forum
and technical paper, there is insufficient evidence of the existence of
substantial market power to warrant the introduction of a rule that restricts
the dispatch offers of generators in the National Electricity Market.[36]
3.31
Similarly, it has also been noted that it may be possible for owners of
transmission rights to withhold transmission rights from the market,
effectively reducing the capacity of the congested interface.[37]
Retail – billing and marketing
3.32
Concerns about the lack of competition in the retail component were also
raised as a contributor to electricity prices:
In the case of retail, the problem is inadequate competition,
and the remedies are the standard competition policy remedies. So I think we
have the types of mechanisms that can deal with issues there.[38]
3.33
Retailer's indicated that in their view they have often received a large
share of the blame for price increases even though they only contribute a small
fraction of the price rise:
As retailers are the billing agent for the entire electricity
industry value chain, we bear much of the consumer backlash over rising
electricity prices while the retail component of the price rises has been very
low.
While retailers have not driven the price rises, we have to
deal with the customer backlash and with the increased customer payment
difficulties they cause while carrying the credit risk for the entire industry
as we must meet our payments to the market generators and networks. Retailers
also believe they have been targeted by the political and regulatory bodies in
response to rising prices even though we have not caused them.[39]
3.34
The committee also noted that changes to billing, marketing and metering
systems have contributed to retail prices increases in NSW of around one per
cent from July 2012.[40]
The committee heard that structural issues may remain for retail competition in
the electricity sector:
But certainly a very large part of the price increases has
really been market failure in a whole lot of areas, in the way retail
competition is structured, in the way networks are regulated—and that is the
work ahead of us. It is not necessarily just keeping prices down, but it is
getting prices to work in an effective, efficient and equitable way.[41]
Retail – generation cross-ownership
and hedging
3.35
The level of cross-ownership between retailers and generators in the
industry has been raised as a potential conflict of interest that may drive
price increases. The ATA informed the committee that:
[I]f we are talking about why the lower wholesale prices have
not been passed through to the retail level, that is because of hedge contracts
that exist—and they are projected out for two or three years, potentially
more—between retailers and generators, often retailers that own their own
generation, and so it takes some time, as we have seen up until yesterday, with
the regulator's decision, for the reduction in the spot market price to flow
through to retail bills, but that does happen.
[42]
3.36
The Energy Retailers Association of Australia (ERAA) responded to the
concerns about cross ownership, stating:
In no state is cross-ownership at such a level that the ACCC
has indicated any concerns about market concentration to date. It comes down to
those risks. When you have a wholesale electricity market that varies in price
anywhere from a negative price to $12,500 a megawatt hour in half-hour
increments, it is a highly risky business. When you have a large retail
customer base where your opportunity to vary your retail prices in line with
movements in the wholesale price is very restricted by price regulation, then obviously
one of the things you do as a natural hedge management strategy, a risk
management strategy, is to have your own forms of generation in case they are
required in peak periods.[43]
Wholesale market prices change in half-hour increments and
can vary in price anywhere from zero, or even a negative price, to $12½
thousand a megawatt hour. Retailers must sell at regulated or their notified
prices so it is retailers, not consumers, who bear the risk in a volatile
wholesale market.[44]
3.37
The ATA also noted that volatility in market prices can drive very
expensive hedging contracts, which ultimately impact the costs of electricity
to consumers:
[O]ne reason is simply the price volatility in the market.
The National Electricity Market has an enormously high cap, $13,000 a megawatt
hour during peak times, and there is significant price volatility, particularly
during peak times, which is driven by our failure to manage that peak. That
leads, by any normal economic theory, to significant amounts of hedging and
costly hedging, because the retailers have to manage their risk in terms of
whether they have to dip into that spot market and pay those high prices.[45]
3.38
The committee heard that the volatility in price can be specific to
particular regions. The AEMC noted South Australia is an example of such
localised volatility in prices:
One of the characteristics of the South Australian wholesale
market is that although average prices have tended to converge, South
Australian prices tend to be more volatile than those in other jurisdictions.
In fact, we have had an average over a week where at one stage the wholesale
price was negative. That volatility is a risk factor which when you are
contracting at the wholesale level tends to increase the costs of
contracting—there is a risk margin in order to manage that volatility.[46]
Business issues
3.39
The committee was informed of a range of business issues and factors
that may contribute to rises in electricity prices, including profit taking,
cost of capital, labour costs, commodity prices and other supply issues. The
following sections briefly summarise each of those potential contributions to
electricity prices across the generation, transmission, distribution and retail
components of the electricity industry. Investment issues are discussed in the
later section on gold-plating.
Profit taking
3.40
Many factors across the electricity industry have been noted as possible
causes of price increases but there is one reason that really stands out to
households: profit taking. The Australian Bureau of Statistics (ABS) dataset
8155 on industry performance indicates that operating profit before tax in the
electricity industry increased from $5.4 billion in 2007–08 to $9 billion
in 2010–11, an increase of 67%.[47]
In the same time period electricity prices rose by over 40%.[48]
3.41
Whether those increased profits are coincidental or opportunistic profit
taking is hard to determine. Mr Nino Ficca of SP AusNet responded to questions
about profit taking, stating that:
Our profitability has been fairly consistent. Investors in
network businesses do not look for disproportionate profits, they look for very
predictable and very stable outcomes. I do not think there has been any
disproportionate profitability—in our sector anyway. It is very much steady and
long-term predictable outcomes. On the cost side, our cost of equity has gone
up substantially post-GFC. Equity markets are very tough at the moment, debt
markets are very tough at the moment and we need to maintain our obligations
both to safety and to reliability from our networks perspective. There has been
that tension. I can say for our business, our profit was flat last year. We had
no increase—I think it was 0.8 per cent over the last year. I do not know, as a
private sector business, that our profits have been growing at anything other
than what you would expect in a normal sense.[49]
Cost of capital
3.42
The cost of capital has increased significantly following the global
financial crisis. The AER has approved an increase in allowed returns on
investment capital of around 1.9 per cent from 2004–05 to 2008–09. The
committee noted that each one per cent increase has been estimated to imply an
additional $780 million in interest payments that are passed on to consumers.[50]
Ergon and Energex described their experiences regarding the cost of capital:
When you look at all our modelling, the major influence on
costs and price at the end of the day is cost of capital. Because our
determination was in 2010 and we came off the back of the global financial
crisis, the cost of debt was significantly higher.[51]
The price that is charged as part of the network charge is
effectively a building block charge, which includes cost of capital, a return
of capital depreciation and operating costs. So a large portion of the charge
is in fact reflective of the cost of capital. That is reset every five years.
When you are in a situation, as we both were in the middle of the GFC,
resetting your regulatory determination and your weighted average cost of
capital, that is where you saw an increase in that cost which flowed through
the network prices at that time.[52]
Labour costs
3.43
While labour inputs to the electricity sector had been relatively flat
between 1996 and 2006, from 2007 onwards they have risen sharply[53]
due to an increase in the size of the electricity supply industry workforce:
since a low of 35 000 employed persons in the November quarter of 2006, the
electricity supply industry workforce has increased to 71 900 employed persons
in the August quarter of 2012.[54]
From its examination of the productivity of electricity and other utilities,
the Productivity Commission reported that:
The rise in labour inputs is confirmed by examination of
company annual reports, particularly those of the major electricity
distribution companies that collectively account for the majority of labour
inputs in the sector. Labour inputs have been increased to upgrade and augment
network infrastructure, to assist distribution businesses respond to ageing
workforces, and to prepare for skills transfer as older workers retire.[55]
Commodity and other input prices
3.44
As many coal-fired power stations have co-located coal mines, the input
price of coal has not necessarily been greatly affected by the unusually high
export coal and other commodity prices that have occurred in recent years,
although some of that commodity price impact is flowing through to consumers.[56]
The committee was informed about the impact of gas prices to date and potential
future impacts:
[W]e have seen significant changes in gas prices in Western
Australia over the last few years, particularly as we have seen gas and coal
prices being determined in a global market. We also see domestic gas demand
rising without necessarily a corresponding rise in supply—hence the cost or
price pressures that were involved in that environment. There is also a lack of
competition in the domestic gas market with the supply side being dominated by
two major suppliers and demand is concentrated effectively in five key
consumers of gas.[57]
[A]lthough gas prices are rising, there is still a lot of
uncertainty as to where they will be in the medium to long term. If you build a
gas fired power station you are looking to operate it for the next 30 to 40
years, but if you cannot take a view on what your fuel cost is going to be then
you cannot work out whether you are going to be competitive in the marketplace.[58]
3.45
The committee also heard how weather conditions had affected particular
types of generation, such as hydro and wind power, during particular periods:
South Australia, for instance, does not have a lot of good
quality coal; it is reliant on gas and, more recently, has had a very high
penetration of wind. In Tasmania there was a period,
particularly during the drought, where energy out of their hydro system had to
be carefully managed.[59]
Technical and reliability
requirements
3.46
The committee was informed of a range of technical and reliability
factors that may have contributed to recent increases in electricity prices,
including service and reliability standards, asset replacement after its
useful life (including catch-up on previous under investment), underground
cabling and metering systems. The following sections briefly summarise each of
those potential contributions to electricity prices across the generation,
transmission, distribution and retail components of the electricity industry.
Service and reliability standards
3.47
Some state governments, including those in NSW and Queensland, have in
recent years increased the standards to which they require networks to operate.
While this improves the reliability of supply, this has also added to the
costs. The Ai Group informed the committee that in its view:
Some elements of the network-related price increase are
related to policy—for instance, policy decisions to have particular reliability
standards. Whether those are good choices or bad choices, there is scope to
improve how the system operates on that front.[60]
3.48
Energex told the committee a review of security and reliability had been
a significant driver in electricity prices in Queensland:
For Energex, the key factors are the improvements in security
and reliability in response to the first Somerville review in 2004 in
Queensland, and also the cost of capital established at our recent reset, which
was in the midst of the GFC, and the demand forecasts at the same time.[61]
3.49
The committee noted that enhanced service standards and reliability
requirements in NSW have contributed to around nine per cent of the approved
capital investment.[62]
The AER reported that, in its view, the reliability settings were above levels
that consumers would value:
[T]he reliability settings for the distribution in New South
Wales have been set above the levels that consumers would value. That has been
the view of AEMC and they have recently come out with a report suggesting that
consumers may find better value with some relaxation of those standards, and
those matters would now be considered by government. They would then feed into
our next round of determinations.[63]
Asset replacement after useful life
3.50
Replacement of assets after their useful life has also been suggested as
a significant contributor to electricity prices. The Productivity Commission
analysed the capital investment in electricity infrastructure and demonstrated
a surge in recent years, as shown in Figure 3.4 below. The Productivity
Commission noted that:
Electricity supply is characterised by periodic surges and
declines in the rate of growth of generation and network capacity. The strong
growth in capital and labour inputs in [electricity supply] from the late 1990s
to 2009–10 is the most recent of a number of investment surges in [electricity
supply] that have occurred over time. It is consistent with the observation
that much of the growth in capital and labour inputs during the period has been
associated with a major program of infrastructure renewal or replacement.
Infrastructure assets built in the mid-to-late 1960s that had
a lifespan of 30 to 40 years would likely have been up for replacement or
refurbishment from the mid-to-late 1990s onwards. Similarly many of the assets
built in the investment boom of the late 1970s early 1980s would also have been
at or near retirement or renewal age from the early 2000s onwards.
Refurbishment and replacement of these assets would also be contributing to the
surge in investment since the late 1990s, and particularly in the past five
years or so.[64]
Figure 3.4: Electricity supply:
Real capital investment ($ million), 1961–62 to 2009–10, constant 2006–07
dollars[65]

3.51
Such asset replacement of electricity networks is estimated to account
for around 31 per cent of the $14 billion of approved capital expenditure in
NSW, which is particularly significant given that networks costs contribute 51
per cent of the overall cost of electricity.[66]
The committee noted that:
The investment needed in the NEM is forecast to exceed $7
billion for transmission and $35 billion for distribution over the current
regulatory periods. This is a rise in investment from the previous periods of
82 per cent and 62 per cent (in real terms) in transmission and
distribution networks respectively.[67]
3.52
During the 1990s there was a significant under-investment in electricity
infrastructure and some of the investment now being undertaken is to
"catch up" on what should have been done then.[68]
In spite of that, inefficiencies in resource allocation are still occurring.[69]
Underground cabling
3.53
The committee noted the impact of an increased usage of underground
cabling, versus poles and wires and the cost impact arising from that. The
overall quantity of underground electricity cabling in place remains small (around
13 per cent) relative to overhead cabling. However, in the most
recent decade around 60 per cent of installed electricity cabling has been put
underground, compared to 20 to 25 per cent in the two previous
decades. Given that the cost ratio of underground to overhead cabling can range
from 2:1 at 11kV to 20:1 or more at 400kV, the greater deployment of underground
power lines can significantly contribute to network costs.[70]
Changes to metering systems
3.54
Changes to billing, marketing and metering systems have contributed to
retail price increases in NSW of around 1 per cent from July 2012.[71]
The Consumer Action Law Centre (CALC) noted that the installation of new "smarter"
technologies in Victoria, designed to better manage energy systems, was also
potentially contributing to electricity price increases.[72]
Policy and regulatory factors
3.55
A range of policy and regulatory factors may have contributed to recent
electricity prices increases, including unwinding of cross subsidies, weakness
in the existing rules, problems with the merits review process, financial flows
out of the sector, such as increased dividend from government owned entities,
renewable energy programs, the carbon price and issues with revenue and price
caps. The following sections briefly summarise each of those potential
contributions to electricity prices across the generation, transmission,
distribution and retail components of the electricity industry.
Unwinding of cross subsidies
3.56
As shown in Figure 3.5 below, average Australian household electricity
prices were relatively constant in real terms between 1991 and 2007. From 2008
onwards, household electricity prices have risen rapidly, with an average
national rise of around 40 per cent in real terms over the last three years.
While the price of business electricity has also risen in recent times, it is
now similar to 1991 business electricity prices in real terms due to
significant decreases in business electricity prices in real
terms during the 1990s:[73]
While there is some variation in the extent of price rises
across the states and territories, they display a consistent upward trend in
prices over this period. These increases have been well ahead of the general
increase in prices and faster than growth in average wages. While the
consumption of electricity makes up a relatively small component of a typical
household's expenditure, these price rises are putting pressure on lower income
households.[74]
3.57
The AER noted 'that upward trends in real household electricity and gas
prices over the past decade in part reflect the unwinding of historical
cross-subsidies from business to household customers that was necessary as
jurisdictions phased in retail contestability.'[75]

gas real index for Australian capital cities[76]

Weaknesses in existing rules
3.58
The committee heard a lot of evidence about the contribution of existing
regulatory arrangements to electricity price increases. This section will
briefly cover some of the impact on cost, while the following chapter will
cover regulatory issues in more detail. The AER informed the committee that the
existing regulations have led to price increases beyond what has been necessary
for a safe and reliable supply:
There have been a range of reasons for recent price
increases—rising generation costs, rising retail costs and the costs of meeting
green schemes have all played a part. But the rising costs of the electricity
network have been the main contributor to price increases in all states. There
are a range of factors driving these increased network costs. The need to
replace ageing equipment and meter peak demand has driven significant network
investment across the market. However, our submission emphasises that, while
much of this investment was necessary, weaknesses in the regulatory
framework—that is, the rules that set out how the AER must regulate prices—have
led to price increases beyond what has been necessary for a safe and reliable
supply.[77]
3.59
The AEMC also noted concerns about the existing rules:
The price and reliability outcomes in this regulated network
sector, in our view, are a function of three things: (1) yes, the rules; (2)
the way the rules are interpreted and applied, including through the merits
review process; and (3) the corporate governance of the businesses involved.[78]
3.60
The committee noted the importance of stability for business to be able
to operate, but was also interested to hear the following view on difficulties
arising from the five year terms of the regulatory determinations:
I think five-yearly price controls setting prices or revenues
for five years and fixing them for that period of time are a very onerous form
of contract. I think that it requires discipline on the part of shareholders
and managers to be able to operate effectively under that, and I think the
conflict-of-interest and other governance issues that are linked to government
ownership of the networks simply have demonstrated quite clearly—the data seems
to suggest—that it has not actually achieved suitable outcomes.[79]
3.61
The committee was told about a particular issue that has arisen in South
Australia, in which South Australians are bearing the costs of cheaper power
for Victorians, noting the proposed rule change to address this issue:
The effect of a generator connecting to the network on how
the rest of the network operates and the capital expenditure required is really
where the major part of the expense is. Under the current rules it is true that
that expenditure on the network is allocated to consumers in South Australia.
Even though the power may be being consumed by Victorians,
the network costs to generate that power are being incurred by South
Australians.
We have a rule change we are dealing with at the moment that
deals with the interregional aspects of the problem, so that if energy is being
consumed by Victorians, even though the transmission kit might be in South
Australia, Victorians will pay for that transmission kit—likewise for New South
Wales and Queensland.[80]
Revenue and price caps
3.62
The committee heard how revenue caps can cause prices to rise when
demand falls. The arrangements with revenue caps were set up some years ago,
when there was consistent growth in demand. However, given that revenue is a
product of price and demand, fixed revenue caps may cause price rises as demand
has fallen in recent times, as explained by the Total Environment Centre (TEC):
Where peak and/or total demand are flat or falling, under a
revenue cap, network revenue remains constant, so networks have an incentive to
encourage more energy saving measures, as any further decreases in costs result
in increases in profits. The downside for consumers is that if demand proves to
be lower than forecast for much of the 5 year determination period, the
networks get a windfall profit, since their revenue was determined by the
original forecast.[81]
3.63
Professor Garnaut held a similar view, stating that:
[I]f demand falls price is increased to make sure that
companies get their guaranteed rate of return. So, as demand has fallen, prices
have had to be increased even more than they otherwise would have been. Of
course, if price then goes up in response to demand falls, then demand falls
even more.[82]
3.64
The Department of Climate Change and Energy Efficiency (DCCEE) responded
to questions on the relationship between demand reduction and electricity
prices, noting that they had work underway to better understand what was
occurring:
The modelling exercise is currently underway. We do not yet
have any final results from that exercise but the modelling is well and truly
underway. We would expect there would be results to hand over the coming weeks.
There is an expectation that there will be public consultation on the basis of
those results and an accompanying regulatory impact analysis of the proposal
for a national Energy Savings Initiative.[83]
3.65
The committee was also informed about problems with price caps, such as
a potential incentive or opportunity for networks to "game" the
market:
Under a price cap the AER divides revenue requirements each
year by the projected units of sales to determine a price. A price cap requires
a 5 year forecast of demand. The price is set on an annual basis; but unlike a
revenue cap, once it is set it cannot be compensated for the following year, so
the networks get to either keep the profit they have made when demand is higher
than anticipated, or are forced to bear the losses when the reverse occurs. A
price cap therefore provides networks with a significant opportunity to game
the market.[84]
There is a lack of market signals out there. If the Reserve
Bank sees the market heating up, they change interest rates; electricity prices
do not.[85]
Merits review process
3.66
Under current arrangements, the AER's revenue and price setting
decisions are subject to merits review in the Australia Competition Tribunal
and this option is frequently used by network operators to achieve higher prices
and revenue caps.[86]
Part of this is perceived by some to be associated with the merits review
process being too easy and the automatic additions of assets to the regulated
assets base.[87]
The AER quantified the extent of this problem in dollar terms:
Our submission also highlighted the impact of appeals of AER
decisions on electricity prices. The outcomes of these
appeals, heard by the Australian Competition Tribunal, have increased revenues
to network businesses by some $3 billion out of some $58 billion over the
current five-year obligatory period. A review of that appeals mechanism is
currently underway.[88]
3.67
Evidence presented to the committee indicated that in NSW, the capital
expenditure overspend (the IPART/Australian Competition and Consumer Commission
(ACCC) approved expenditure) has grown from a few $10s of million 2004–05 to
almost $600 million in 2008–09. The Department of Resources, Energy and Tourism
(DRET) went on to note that:
...an overspend does not imply this additional expenditure is
inefficient. Capex overspends may be an efficient response to a range of
legitimate drivers; for example, as a result of changes to reliability
standards and demand outcomes being different to what was forecast. However, it
is essential that consumers have confidence that the regulatory framework does
not incentivise unnecessary investment.
The ability of the AER to test the efficiency of overspends
is a matter currently being reviewed as part of the AEMC’s Economic Regulation
of Network Service Providers rule change process.
The AEMC’s draft rule provides for new tools under the National
Electricity Rules (NER), such as capital expenditure sharing schemes and
efficiency reviews of past capital expenditure so the AER can incentivise
network service providers to invest capital efficiently. [89]
3.68
Professor Garnaut drew the committee's attention to the lack of
opportunity for counter appeal by the regulator and suggested that allowing
counter appeals by the regulator may contribute to keeping prices down:
[T]he rate of return is set by the regulator. It can be
appealed by players in the industry and there is no opportunity for counter
appeal by the regulator. So removing that unusual imbalance, in which those who
want higher prices can appeal the regulated outcomes but there cannot be a
general counter appeal by the regulator, would make a contribution. If that
were removed it might simply be a matter of the regulator applying, more
rigorously, commercial and economic principles, because there is no doubt that
the rate of return has been set substantially in excess of the supply price of
investment to this industry. The test of that is that anyone who happens to own
a regulated asset would not be prepared to sell that asset for an amount of
money equal to the regulated asset base. They would want a premium, which shows
that the rate of return that is being allowed on the investment is higher than
the supply price of investment.[90]
3.69
The department informed the committee that the AER and SCER are
examining whether the merits review process can be improved.[91]
Financial flows to
state-governments
3.70
The Prime Minister noted that some state and territory governments have
been profiting from price increases under current regulatory arrangements:
[I]n many places around Australia, the State Governments both
own lucrative electricity assets and regulate parts of the electricity market.
The comparison between the private and public owned utilities
shows the States are doing very well financially out of this arrangement.
Following the recent round of price increases, revenue for
network enterprises wholly owned by State Governments is up fifty per cent over
the previous five year period.
In other words, revenue to the states went up nearly twice as
fast as revenue to the private network operators.[92]
3.71
A presentation recently delivered by the Energy Users Association of
Australia (EUAA) Executive Director highlighted the discrepancies in
distribution prices between private and government owned entities as shown in
Figure 3.6.
Figure 3.6: Distribution prices[93]

3.72
DRET noted, however, that the characteristics of the market vary in each
state and territory and this could influence any cost comparison analysis. For
example, cost comparisons between state and privately owned utilities may not
take into account the length of the NEM in each jurisdiction and other
differing attributes.
3.73
The NSW government budget papers provided an overview of the dividends
and corporate tax revenue it receives from its utilities. The tables below
provide a breakdown of these sources of revenue. They indicate the NSW
government will receive $999 million in dividends from electricity generation
and distribution and transmission and an additional $546 million from Snowy
Hydro in 2012–13. There is a decrease in dividends from electricity generation
from the previous year of $83 million and an increase in distribution and
transmission dividends of $262 million. Both categories of energy
dividends then decrease over subsequent years.[94]
Figure 3.7: NSW government
Dividends and Income Tax Equivalent Revenue[95]

Figure 3.8: NSW government 'Other
dividends and distributions' (Snowy Hydro Limited)[96]

3.74
The NSW Treasurer, the Hon Mike Baird MP, has outlined that the revenue
from the electricity dividends is reinvested in the community to fund schools, hospitals,
transport and police.[97]
3.75
Chapter 8 of the Queensland government budget strategy papers provided
an overview of its 'public non-financial corporations sector'. It indicated the
Queensland government will receive $727 million in dividends in 2012–13 from
the energy sector.
Figure 3.9: Queensland government ordinary
dividends[98]

3.76
Professor Garnaut noted that it was essentially a policy question for
the relevant state government and they could choose to lower electricity
prices:
The question is different in publicly owned and privately
owned networks. Where they are publicly owned—and this is
overwhelmingly the case in New South Wales, Queensland, Western Australia and I
think Tasmania—the issue does not involve any effect on the wealth of private
firms. Here it is a straightforward public policy question. Really the question
is: is artificially raising the price of electricity a good way for these
governments to raise revenue? I would suggest that it is generally not a good
way, and it is within the power of the governments themselves to apply a lower
rate of return and bring down electricity prices. That will have an effect on
government revenue. I would expect that there will be alternative forms of
revenue that could give you the fiscal effect you want at much lower cost to
the community.[99]
Renewable energy
3.77
Greater usage of more expensive renewable energy systems and Renewable
Energy Targets (RET) have also been suggested to contribute to both price
increases as well as price decreases, as explained by the REC Agents
Associations:
The renewable energy target, which is a national scheme, has
come in for a bit of criticism from some quarters and is blamed for a large
part of the increase in retail electricity prices. While it is clear that the
renewable scheme has contributed to rising power prices, it is currently less
than 1c per kilowatt hour, which is roughly equivalent to 3.4 per cent of
retail prices, and a similar amount is due to state based schemes. Importantly
though, the cost of the national renewable scheme is expected to reduce. That
is the direct pass through of cost; however, the implementation of solar
systems has led to a reduction in electricity demand and we have seen wholesale
prices fall quite a lot over the last few years. That is because there has been
more competition from generators to meet a lower demand. So renewable energy is
actually contributing to lower wholesale prices.[100]
3.78
Professor Stuart White from the Institute for Sustainable Futures at the
University of Technology Sydney (UTS) also noted that were there any cost
increases, these were small compared to network costs:
One is the impact of environmental requirements, of which the
mandatory renewable energy target is one. ... that is a factor in the increase in
prices, and of course many state based schemes have increased the price. But it
is small relative to the network spin. So the second factor you mentioned,
about increasing the value of assets and so on, is probably a much larger one.
The spending on networks is $45 billion—an awful lot of money, and that swamps
the impact of such measures as the mandatory renewable target, the feed-in
tariffs and so on, many of which are being phased out in any case.[101]
3.79
In addition, the Ai Group suggested the RET can put downward pressure on
prices, in both the small and large scale schemes:
But there are some countervailing effects from the two
components of the RET. So the extra generation that the LRET brings on has to
some extent—and there is some controversy over the size—a depressing effect on
wholesale electricity prices. Some observers think that that is strongest in
South Australia, where most of the wind capacity is, and less significant
elsewhere. The small-scale scheme, where most of the activity has been over the
last couple of years, may be playing a role there as well—although that is even
more complicated to assess.[102]
3.80
Professor Garnaut also noted the downward pressure on price from the RET
and noted that it may contribute to lowering the carbon price:
The steady expansion of renewable energy supplies under the
RET is forcing down wholesale prices, and it is possible, although not certain,
that in the middle of 2015 with the linkage to the European market we would
have a lower carbon price than we do today.[103]
3.81
The committee was also informed of the complexity and variables involved
in forecasting Renewable Energy Certificate (REC) prices and that the current
RET review may provide some helpful analysis:
In forecasting REC prices, though, there are an enormous
number of variables around demand and the wholesale electricity market factors
relating to local planning requirements for building specific projects, the
costs of individual renewable technologies. There are a whole range of factors
that come into play in forecasting future REC prices that make it extremely
difficult. I should say that the RET review that is currently underway would have
some type of analysis of what those prices may be to achieve different targets.[104]
Carbon price
3.82
The carbon price was forecast to increase electricity prices by around
10 per cent[105]
and that appears to be occurring in practice: witnesses cited figures of six,[106]
9.5,[107]
10[108]
and 15 per cent.[109]
Network investment and gold plating
3.83
Of all the areas potentially responsible for electricity price rise
network investment appears to be the largest and is therefore attracting a lot
of attention. The Productivity Commission pointed to NSW electricity bills
between 2007–08 and 2012–13 in which a typical total bill went from $1100 to
$2230, with the network component growing by 130 per cent from $505 to $1159.[110]
In other words, the network component in 2012–13 is now more than the total
bill was in 2007–08.
3.84
The Prime Minister noted that current regulatory arrangements create an incentive
to overinvest in infrastructure and pass on the costs to consumers.[111]
Part of this is perceived by some to be associated with the merits review
process being too easy and the automatic additions of assets to
the regulated assets base;[112]
the department noted its observations regarding the impact of network costs on
electricity prices:
The department is obviously aware of recent increases in
electricity prices for consumers and we are aware that rising network charges
are a common driver as significant investment is required in new and ageing
networks to meet rising demand and ensure supply reliability.
Climate change policies have also put
upward pressure on prices, but we note the government is providing targeted
assistance to help households adjust to cost increases arising from the carbon
price.[113]
3.85
The committee received lots of submissions and oral evidence on the
over-investment in networks. For example, Dr Ray Challen of the Department of
Finance (Western Australia) stated '...I agree that there is that incentive for
over-investment in network assets'.[114]
Other examples included:
The protected monopoly companies take the opportunity to
overinvest or "gold plate" their networks because the regulatory
regime has encouraged them to do so.[115]
To date the NEM has conveyed efficient pricing signals and
delivered the necessary investment in the right place at the right time. In
real terms, the wholesale prices for electricity have not increased over the
life of the NEM. The competitive generation market has also responded very
quickly to the changed outlook; however, regulated investment has not.[116]
The growth in capital expenditure over
the past five years in networks has therefore outstripped the growth in both
energy and peak demand and contributed to those rises in retail prices. While
some of that expenditure has been necessary to deal with ageing assets, it is
not clear that all the expenditure is supported by either the age of the
network assets or the growth in demand.[117]
So the problem with the increased network spend and the
flattening or even decreasing sale of kilowatt hours is a structural issue. It
costs you more to sell less of your product, and therefore prices will
inevitably spiral.[118]
[T]he important thing is the network spend. It is just far
and away the biggest component of the bill increase, so it has to be, I would
suggest, the most significant thing that you would focus your attention on.[119]
3.86
The AER's 2011 State of the Energy Market report showed that
NSPs' revenue has been increasing in line with increasing network investment
(see Figures 3.10 and 3.11).
Figure 3.10: Energy network revenue[120]

Figure 3.11: Energy network
investment[121]

3.87
In contrast to much of the evidence presented to the committee, SP
AusNet indicated that in their view there are instances where network costs
have fallen, such as in Victoria.[122]
Grid Australia also noted that investment in transmission infrastructure has
not been as great as in distribution infrastructure and that it can assist in
lowering electricity prices:
Grid Australia members are currently spending at or below
approved forecast expenditure needs for their current regulatory control
periods. This is consistent with and responsive to demand in growth that is
generally below forecast expectations. In some cases this is a result of
deferred expenditure on identified projects. It is also worth noting that the
Australian Energy Regulator—the AER—has found that transmission investment is
forecast to plateau for transmission businesses this year. This is in contrast
to the AER's prediction that distribution network costs will continue to rise.[123]
Unlike distribution networks though, strategic investment in
transmission helps increase interstate electricity trade and generator competition,
getting consumers the lowest cost and efficient generation and, in doing so,
helping to reduce power price rises.[124]
3.88
Some of the arguments against the existence of gold-plating include that
other methods, such as new minimum service standards and demand reduction
activities, have permitted reductions in capital expenditure:
Energex has worked with the Queensland government through the
second Somerville review during 2011 to assess the effectiveness of the
security and reliability standards. As a result of this review, the minimum
service standards have been stabilised or flat-lined and the security standards
have been broadened to provide more efficient options. Together, the adoption
of these changes in conjunction with the forecast moderation in network demand
growth compared to previous forecasts has allowed us to reduce our capital
expenditure over the current regulatory period by a further $850 million. The
benefits of these expenditure reductions have been passed through in our
network charges in the form of price discounts in 2012-13.[125]
3.89
Other arguments against gold-plating having occurred postulate that
external factors beyond the control of the network businesses are to blame:
ENA's submission explains how a perfect storm of high capital
costs, higher government reliability standards, replacement of ageing assets
and the need to service rising peak demand have all combined to push up network
costs. ENA members appearing before the committee have explained that these
factors are likely to moderate in the near term. Many businesses expect that
future cost increases will be in line with inflation or perhaps even lower.[126]
[R]egulation to hold down retail electricity prices is
self-defeating because the true costs of electricity need to be met somewhere,
either through electricity prices [or] through the taxation system. Since
regulated prices rarely keep pace with market developments, built up pressures
can lead to sudden changes, larger than those the market would produce.[127]
3.90
Others informed the committee that, in their view, the regulatory
arrangements were more at fault than the businesses. For example, Dr Paul
Troughton argued that 'I am not accusing anyone of acting badly...Everyone is
just responding to the incentives that are in place in the existing regime'.[128]
3.91
The Productivity Commission suggested that 'it is important not to blame
network businesses for the current inefficiencies. Mostly, they are responding
to regulatory incentives and structures that impede their
efficiency'.[129]
3.92
Professor Garnaut elaborated on the reasons for the regulatory failure
and observed that the high rate of return was very likely to cause wasteful
over-investment and upward pressure on prices:
Excessive price increases have reduced demand, and we
guarantee a rate of return under our rate-of-return regulation. It is basically
a riskless rate of return; there is not even exposure to the market...A completely
unsustainable situation can emerge and I think that we are in that
unsustainable situation now.[130]
3.93
The committee heard that some steps are already being taken to address
the regulatory issues (these are discussed further in the next chapter):
The other thing that is important to note is the regulation
of networks has been subject to a recent rule change proposal. That has been
under consideration by the Australian Energy Market Commission and continues to
be under consideration by the Australian Energy Market Commission... there is a
draft ruling out at the moment. We would expect a final ruling by the end of
the year.[131]
Committee comment
3.94
The committee has been informed about a large number of factors which
contribute to electricity prices and recent increases in these. Some of these
factors are contested, while others have wider acceptance. For some factors,
while the price increases may seem perverse to somebody outside the electricity
industry, it is apparent to the committee these have probably arisen as a
result of historical technical and regulatory artefacts.
3.95
The committee considers that the following factors (shaded factors in
Figure 3.3) have made significant contributions to household electricity
prices rises:
(a) peak demand;[132]
(b) overestimated demand forecasts;
(c) opportunistic profit taking;
(d) gold-plating of networks;
(e)dividend extraction by state governments;
(f) revenue caps causing price to rise when demand falls;
(g) hedging arrangements to protect against price volatility in the NEM;
(h) labour prices;
(i) greater use of underground cabling;
(j) replacement of assets after their useful life;
(k) lack of competition in some retail sectors; and
(l) unwinding of cross subsidies between business and household customers.
3.96
The committee notes that factors (a) to (f) above are strongly
influenced and enabled by the current regulatory arrangements which have set
regulated returns at too high a level, as described by Professor Garnaut.[133]
The committee further notes that the other unshaded factors in Figure 3.3 may
have also contributed to electricity prices.
3.97
While the committee is convinced of the contributions to electricity prices
discussed above, the committee is concerned that efforts to address these
issues are hampered by a lack of quantitative information about their exact
contribution. The committee notes the useful breakup of contributions to future
electricity prices provided by the AEMC, which includes factors such as
transmission, distribution, wholesale, retail, carbon price, feed-in tariffs
(FiTs), LRET, SRET and other state based schemes (see the discussion earlier in
this chapter for the contributions). However, this does not provide sufficient
information about other factors.
3.98
The committee therefore considers that it would be very beneficial if
the AER was to provide more detailed ongoing quantitative monitoring of a much
broader range of the factors contributing to electricity prices, including
those identified in this report.
Recommendation 1
3.99
The committee recommends that the AER provide an annual report
including detailed quantitative analysis of the components of and contributors
to electricity prices.
3.100
The committee observed that for many factors contributing to electricity
price rises, where the information and evidence around those individual factors
is considered in isolation, the price increases may seem appropriate and
logical. However, the overall electricity price increases experienced by
Australians are completely inappropriate and unacceptable. The ATA noted that:
Whilst there are many improvements that would reduce prices
for consumers, a fundamental problem with the disaggregated structure of the
energy market is that typically no single business can make a sound business
case to promote any one of these improvements for consumers, based on the
benefits to their part of the supply chain.[134]
3.101
From the committee's perspective, many stakeholders have appeared to
argue that the price rises occurring in their components or factors are fair
and logical, while the price rise of other components is the real problem. The
committee considers that there needs to be a greater collective responsibility
taken for overall electricity prices. This view is supported by a report
commissioned by the CALC:
The draft report provides a comprehensive overview of policy
and regulatory developments with a specific focus on wholesale and retail
markets, demand side interaction, market structure and efforts to tackle carbon
emission reductions. The draft report argues that in Australia at present,
consumer welfare is given insufficient attention by Australian policy makers
and regulators, and throughout the report recommendations are made to inform a
policy and regulatory framework that has a more rigorous focus on the interests
of consumers. The draft report draws on international development, particularly
from Europe and the UK, where there has been acknowledgment that the interests
of industry did not 'trickle down' to satisfy the needs of consumers.[135]
3.102
The committee supports the related conclusion and way forward proposed
by the Productivity Commission:
The overarching objective of the regulatory regime is the
long-term interests of electricity consumers. This objective has lost its
primacy as the main consideration for regulatory and policy decisions. Its
pre-eminence should be restored by giving consumers much more power in the
regulatory process.[136]
3.103
The committee is therefore of the view that there needs to be better
ongoing arrangements for managing electricity prices in the overall electricity
system to ensure that price setting for individual components and factors is
done in the context of keeping overall electricity price rises and the rate at
which these occur at a more acceptable level. In other words, the committee
recommends that those bodies setting prices at the individual component or
factor level should have regard to and justify the impact on overall
electricity prices.
Recommendation 2
3.104
The committee recommends that ongoing arrangements be put in
place to more effectively scrutinise prices in the overall electricity system,
and ensure that price setting for individual components and factors is done in
the context of keeping overall electricity prices at a more acceptable level.
