Incentives and disincentives for Utility driven DSM in Brazil
Gilberto De Martino Jannuzzi

1. Introduction
Although Brazil has shown support towards energy efficiency since the mid eighties with the
creation of PROCEL, the National Electricity Conservation Program, in practice its overall
performance to control and plan electricity demand has been modest and suffered
discontinuities during the following decades.
This was especially aggravated in the early nineties when the country started its power sector
reform implementing changes in the management, organization, ownership and decision-
making of its electricity sector. Privatization was one of the initial steps of the process which
aimed to attract private investments and create competition within the industry.
Nevertheless, new charges to electricity customers were created in order to secure funds for
energy efficiency activities during this period. The main motivation was to ensure provisions
for energy efficiency as privatization progressed and address the lack of interest of utilities in
energy efficiency activities.
The main objective of the present paper is to analyze existing incentives and disincentives for
utility-driven DSM programs as results from regulations and market signals. In order to do that
it is presented a brief historical overview of the legislation and related regulation that was
established to provide support to energy efficiency. The main current laws, decrees and
regulation are discussed in more details. Examples of utilities’ programs are presented to
illustrate how utilities perceive their interest in EE and allocated funds to the projects. In the
concluding section the main problems regarding active engagement of utilities in EE programs.

2. The legislation and regulation on Energy Efficiency

    2.1. Evolution (1998-2007)
Efforts to secure funds and activities in EE started in a more systematic way in 1998 when the
regulator ANEEL established mandatory investments to privatized utilities.
Table 1 presents the main Laws, Presidential Decrees and regulations that set the levels of
compulsory investments in EE and R&D done by utilities. Several changes occurred not only
regarding the amount of funds destined to EE utilities’ projects but also how these resources
should be spent by utilities (Figure 1). These later have been subjected to ANEEL’s regulations
and are set either by Resolutions or by Guidelines (Manuals) for EE program design and that
have to be followed by the regulated electricity distribution utilities.
In 1998 the regulatory agency ANEEL defined the amount of annual investment, procedures
for submission, approval and verification of privatized utilities’ energy efficiency programs.
Since then, ANEEL revises annually the criteria for approving energy efficiency, which are
conceived and implemented by utilities. It was established that 1% of the annual net revenues
of the distribution utilities had to the invested in annual programs, both for energy efficiency

                                                                                                     2
and energy R&D. It is important to observe that these funds are collected from electricity
customers1 and do not affect utilities profits, this will be further discussed in section 3.
In year 2000 the Bill 9.991/00 approved by the National Congress made explicit provisions for a
public benefit fund called CTEnerg, a fund managed by an appointed Board of 9
representatives from the Ministries of Science and Technology, Energy and Mines, Public
Research Agencies, the Academia and Private sector. This Bill allocates part of the 1% annual
utilities’ revenues for CTEnerg and other part remains within utilities (generation, transmission
and distribution), being spent in efficiency and R&D programs (Table 1).
CTEnerg has the mandate to allocate investments in “public interest R&D and EE” projects. Up
to now almost all of its investments have been to energy R&D, and very little to EE (about 5%
only). The types of investments related to EE have been directed towards training, and the
upgrade of several national metrology laboratories, that could offer support for testing
appliances and energy consuming equipment.
Only distribution utilities are responsible for the design and implementation of energy
efficiency programs2. These programs up to year 2007 had to be previously submitted to the
regulator, and upon approval, implemented under the Regulator’s supervision. Bill 9.991/00
extended the 1% obligation to transmission and generating companies (only investments in
energy R&D programs) and included private and state-owned companies. This Bill also
established that only end-use EE programs would be considered for investments.
Changes were introduced in Bill 9.991 through Bill 10. 10.8483, decree 5.879 and finally Bill
11.465, which extended the allocation of 0.50% of annual utilities revenues up to 2010 (Bill
9.991 stated a reduction to 0.25% after 2006).
During 1998-2000 part of the regulated investments could be used in supply-side efficiency
programs. Since utilities were responsible for the selection of programs, their design and
implementation, a significant amount was used to reduce utility’s energy losses, including
commercial losses during this period4. Bill 9.991/00 determined that only end-use utility’s
programs should be funded out of the wirecharge, since it was understood then that supply-
side investment, i.e. improvements in energy efficiency within the utility premises, or its
distribution system, should be considered as part of their business strategy to maximize
profits.
Initially, marketing was also another area that attracted utilities’ investments until year 2000,
after that this type of projects has not been allowed as part of the regulated energy-efficiency
programs.

  In this paper we will refer to this tax as wirecharge.

  Funds collected by Generating and Transmission companies are destined to regulated R&D programs
supervised by ANEEL and another part is allocated to CTEnerg (Table 1).
3
  It is important to register that during the discussion of this Bill in the Congress, initial drafts proposed
drastic reduction of the funds to EE and R&D. The approval of this Bill implied in a final reduction of 20% of
the funds originally allocated to EE and R&D.
4
  Nearly 70% of investments in Utilities’ programs implemented during 1998-99 were destined to supply
side efficiency projects, including projects to reduce commercial losses (Jannuzzi, 2000, Jannuzzi, Gadgil
et al 1998).

    Figure 1: Evolution of ANEEL’s Resolutions and Manuals reflecting major changes in
        rules related to change types of projects allowed and allocation of resources

Note: A list of the relevant Legislation and ANEEL’s Resolutions is presented in the Annex.




An analysis of the several ANEEL’s manuals and Resolution that were conceived during 1998-
2007, illustrated in Figure 1, shows emphasis on guidelines for formal procedures preparing
documentation and justification of proposed projects, and less preoccupation with exploring
wider technical aspects of energy efficiency5, evaluation and performance of the proposed
projects.
Over the years, ANEEL has determined compulsory expenditure shares for residential,
commercial, industrial programs. This procedure which fixed percentage expenditure shares
has to be observed by all utilities (a total of 64) in the country and has not considered local
market specific characteristics, missing some opportunities and sometimes forcing expenditure
on less cost-effective programs.

       2.2. Recent regulatory efforts
In year 2007 ANEEL started to implement changes in the way it regulates utilities’ investments
in EE programs. Greater effort is being placed on monitoring, evaluation and verification of
results. Utilities will be required to present an evaluation plan which will be subject to the
regulator’s approval and third party verification. The new rules will give greater flexibility to

  Some distortions regarding concepts of energy efficiency can be observed in ANEEL rules for approving
EE utility programs. For example: projects that consider changes in technology that use solar, natural gas,
or other fuel replacing electricity-based technologies are not permitted. The replacement of electric
residential showers (chuveiros) was only permitted after 2002 to be included in the utility EE annual
program.

                                                                                                                                          4
utilities to design and implement their programs, but the claimed saving will be evaluated.
Oddly enough, investments on supply-side EE is going to be allowed.
A new manual was submitted to public consultation during December/07, but it has not been
released so far.

Notes: Since year 2000 only end-use energy efficiency projects can be financed (Law 9.991/2000). Generators using renewable resources (solar, wind, small hydro-plants
and biomass) are exempted from these requirements. † Since year 2004, 0.10% is destined to support the activities of the EPE, Energy Planning Company, owned by the
Ministry of Mines and Energy, after 2006 EPE will get 0.10% of annual revenues from distributing utilities; for T&D utilities the % allocated to EPE is 20%).

3. The persistent disincentive: lost revenues
However, up to now ANEEL has not addressed the main utility disincentive: the lost revenues
resulting from energy efficiency programs. This affects not only private, but also the few
remaining public utilities6. This issue has not yet being considered during the latest revisions of
the EE program discussed during the year 2007.
The key factors affecting their motivation for engaging in energy efficiency programs can be
summarized as: (a) concessions are owned by profit-oriented corporations (more than 80% of
electricity is sold by private companies); (b) they sell electricity at a given fixed tariff which is
revised each 5 years and has annual adjustments for inflation.
The current tariff system in Brazil is a mix of price-cap and revenue-cap regulation. Every five
years a tariff revision is performed for each utility consisting of an estimated stream flow of
revenues (revenue-cap) and a fixed tariff (price-cap) is assigned to cover the projected
expenses, productivity gains and margin for profits. Within the five-year period, tariffs are
corrected by inflation indices annually.
Since the tariff is fixed, the only way for utilities to increase their profits is to increase their
sales (i.e. more kWh sold). Utilities only have interest in EE in very specific cases, when they
perceive a direct benefit to them: reduction of commercial losses, investments in less
profitable markets in order to meet the demand of other segments without new investments
in the distribution sector, etc.
The current formula used for tariff revisions is composed by 3 factors that include the variation
of costs incurred by the distribution utility:
                                                A+B+X


Where
       A is the component that includes costs that are passed directly to consumers, this
        factor includes transmission and energy purchases from generators, several taxes
        collected by the government through the utility Bill, including the investments in
        energy efficiency (and R&D as well). The component A includes represents about 75%
        of the distributing utilities revenues. These costs are not controllable by distributing
        utilities.

       B is the component that includes all operational, depreciation of utilities’ assets and
        the permitted utility’s profit margin. This cost component can be managed by the
        utility and represents about 25% of its revenues.

       The factor X allows for adjustments to compensate gains in productivity levels or
        compensate losses. Its value is set by ANEEL7.



6
  In particular those state companies that are candidates for being privatized and need to keep their
economic performance in order to be better evaluated by potential buyers. Most public owned utilities have
private shareholders and bonds in stock markets.
7
  Perhaps, eventual gains or losses accruing from a CDM project can be included in this factor, if the
regulator permits.

                                                                                                         7
This procedure for tariff revision gives incentives for utilities to demonstrate the need for
greater investments increasing the component B of the above formula. The utility that
implements good EE programs and therefore reduces the need to expand its distribution
system (B is lower) is penalized twice: it will have smaller sales and will be given a lower tariff
as compared to another utility which does not implements good EE programs. It is important
to note that the funds for EE are collected from electricity consumers as a wirecharge and are
not part of utilities’ costs (which are considered under component B of the formula), i.e.
utilities design and implement EE programs with their customers’ funds.
This fact explains the logic behind most of programs proposed and implemented by the
Brazilian utilities. In the next section we try to characterize the major programs that have
being implemented to illustrate their preferences for EE programs with less impact on total
revenues.

4. Characteristics of energy efficiency investments done by utilities: an
   overview of past investments

       4.1. The Brazilian electricity sector and investments in EE
The Brazilian electricity sector has approximately 100 GW of installed capacity, 76.53% of
this is hydroelectric and 21.22% thermoelectric. About 187 million consumers were
responsible for 390 TWh in 2006 (BEN, 2008). Since 2001 more than 80% of the electricity
is sold through private distribution utilities. This contrasts with the situation on the generation
side, which is dominated by state-owned companies, responsible for generating 377.7 TWh,
about 90% of electricity production in 2006 (BEN, 2008). The average annual percentage
growth in electricity demand during 1990-2000 was 4.1%, dropping sharply by -6.6% in 2001
due to the power crisis and rationing which lasted from June 2001 through February 2002.
Electricity growth during 2002-2006 was approximately 4.7% per year, indicating a
recuperation of economic activity after the crisis.
Electricity sales measured in current dollars, using data from total electricity consumption and
national yearly average tariffs, shows that the total has been stable in recent years around US$
15 billion per year up to 2003. However, due to tariff increases allowed by the regulator during
2004, partly to compensate utility revenues losses during the power crisis, total sales can be
estimated to have reached approximately US$ 29 billion in 20068, therefore about US$ 145
million is invested annually in EE utility’s programs.
The regulation introduced since 1998 increased several times the amount of investments in
energy efficiency traditionally done by PROCEL, in year 2000 for example, regulated
investments were nearly 6 times higher than PROCEL’s expenditures. Even with changes in the
legislation that has reduced the percentage of sales revenues dedicated to efficiency programs
regulated investments are several times higher than the amounts previously invested by
PROCEL.

4.2. The disconnection of utilities’ EE programs and the electricity
           market
Seven utilities9 alone were responsible for more than 70% of the total investments made in EE
programs during 2003-04. The remaining 57 utilities located in more dispersed areas of the
country have smaller programs and probably higher costs associated with their
implementation and face different market conditions to exploit energy efficiency potentials.
The regulator has not yet considered in any significant way different approaches to address
the differences between utilities.

Figure 4: Total investments by utilities by main sectors during 1998-2003 (millions R$)



Public lighting is estimated to account for approximately 3% of total. However, improvements
in public illumination systems (mostly changing incandescent lamps for mercury vapor and

                                                                                                                  10
mercury for sodium high pressure lamps) have represented almost half of the investments in
end-use programs. These have been the most cost-effective investments for utilities so far and
convenient applications. The predominance of public lighting can be better understood when
we consider the government program RELUZ administered by PROCEL and EletrobrĂĄs. This
program started in 2000. RELUZ can finance 75% of the investment in of new public lighting
systems at very subsidized rates of interest.10 The financing is via the utilities. The “1%
obligation” funds can be used to provide the remaining 25% share, but the RELUZ funds can be
counted towards the fulfillment of the “1% obligation. Other reasons also explain the
preference for public lighting programs:

        Municipalities pay a relatively low tariff for public lighting, despite its impact on peak
         load demand and their often poor payment history. From the utilities’ perspective,
         investing in public lighting EE has been a way to minimize losses from their sales to
         municipalities, while at the same time taking advantage of the RELUZ.

        Since 2002, the minimum cost-benefit ratio required for approval is >15% higher than
         for all other types of projects.

        As shown below, public lighting projects are substantially larger than in other sectors,
         which may be attractive from an administrative point of view.

Initially, marketing was also another area that attracted utilities’ investments until year 2000,
after that this type of projects has not been allowed as part of the regulated energy-efficiency
programs.



     4.3. Low income EE programs
Since year 2005 regulation required that at least 50% of total investments by utility should be
in low income households programs and for most utilities this has been the main focus of their
programs since then. Table 2 shows the allocation of investments during 2005-2007, as it can
be seen the average value (more than 60%) higher than the required minimum indicates that
utilities have interest in these programs.

  The interest rate and payment conditions are very favorable, considering existing market conditions in
Brazil (5% interest/ year), while rates for BNDES loans are ~15%.

The types of low income programs implemented by utilities in low income households are:
replacement of incandescent light bulbs for CFLs and replacement of refrigerators,
improvements in internal wiring, solar water heaters and regularization of connections (Table

Several utilities in Brazil have large commercial losses in this category of consumers due to
illegal connections (power thefts), difficulties with bill payments and insolvency of these
customers. By reducing their electricity bills and improving their connections there is greater
chance of reducing the losses in sales.

    4.4. Some economic indicators of utilities’ EE projects
From 2001 a cost-benefit ratio of 0.85 was required in order to approve EE projects. That was
the first time an economic parameter was required for the ex-ante evaluation of programs
submitted to ANEEL.
This cost-benefit ratio is an ex-ante indicator that considers the estimated annual savings
accruing from a specific project over the annual cost of the project (capital costs are
annualized and O&M annual costs are included). It was also required that each project have
targets that could be quantified and verified. The initial ideas was to create an indicator that
permitted a better screening of potential projects, ensuring some measure of comparison

                                                                                                    12
between similar projects from different utilities. In 2002 Public Lighting projects could yield a
C/B ratio of 1.0.
Table 4 presents some examples of C/B ratios and related calculations of cost of saved
electricity ($/kWh) and avoided demand ($/kW). These examples show that for similar values
of C/B ratios different values for the cost of conserved electricity (CCE) and avoided capacity.
All listed programs had their cost of saved electricity higher than the costs of electricity sold in
the spot market during the year 200311.

Data collected from the approved utilitiesÂŽ annual plans (ANEEL, 2005) suggests that the cost-
effectiveness of EE programs may vary greatly due to the significant differences of scale (Table
4). Even if we compare projects under the same category we note large differences in
expenditure. For instance, utilities’ public building EE projects vary from R$ 1,646 to R$ 3
million, while public lighting programs range from R$ 32,000 to R$ 20 million (Table 5). The
expenditure patterns of utilities’ EE programs are varied. The investment costs per project

range from a few thousand R$ to almost R$ 20 million. The analysis of EE projects by major
categories indicates the predominance of public lighting as the largest projects implemented
by utilities, with the average project costing almost 10 times more than the projects
implemented in public buildings and more than 3 times the average cost of industrial sector EE
projects.

5. The incentives
It is important to highlight that some utilities (only the large ones, such as Eletropaulo-AES,
CEMIG, mainly) have started to see business opportunities with EE in their concession areas.
These utilities have created their own ESCOs, and as an unregulated activity (different from the
electricity sector) and they can operate in other concession areas and capture economic
returns on their investments in energy efficiency12 . They operate in markets with large and
sophisticated costumers and are able to develop business proposals improving the energy use
and also sell other services and equipments.
Many utilities have also used EE programs as part of their strategies to retain their large (and
non-captive) consumers13.

6. Concluding remarks
We consider that there are still strong disincentives for utilities to undertake EE programs as
part of their business strategies. The “lost revenues” issue is the main barrier for utilities to
approach end-use efficiency.
The almost 10 years of existing compulsory utility EE programs have shown that they always
seek ways to invest in markets that represent lower revenues, or large commercial losses. Even
the cost effectiveness of many of these programs can be shown to be less attractive than
purchasing electricity on the spot market or the marginal cost of electricity production.




12 ANEEL started to introduce accounting procedures to ensure that economic benefits from investments
done under the 1% obligation are also returned to consumers, at the time utilities’ tariffs are reviewed.
13 Non-captive consumers are the ones with demand greater than 3 MW and can choose their electricity
provider.

                                                                                                               14
Also, the lack of more comprehensive studies on the existing potential for the introduction of
energy efficiency measures in the Brazilian market together with better program evaluation
practices have, in our view, limited the benefits accruing from potential electrical system-wide
impacts from these programs. ANEEL’s role as the supervisor of utilities programs could be
further enhanced with more coordination amongst individual programs and better knowledge
of EE potentials.
ANEEL’s Resolutions are powerful means to direct utilities’ investments to certain desired
energy programs and they can be implemented speedly dependending on the regulator
interpretation of the current legislation and after the process of public consultation.
We understand that the factor X in the current Tariff revision formula scheme is one plausible
mechanism to reward companies that are implementing good EE programs, and also
compensate those that report losses in sales revenues.

Incentives and disincentives for Utility driven DSM in Brazil

  • 1. Universidade Estadual de Campinas Incentives and disincentives for Utility driven DSM in Brazil Manuscript prepared for GTZ Gilberto M Jannuzzi 07/02/2008 Final Report
  • 2. Incentives and disincentives for Utility driven DSM in Brazil Gilberto De Martino Jannuzzi 1. Introduction Although Brazil has shown support towards energy efficiency since the mid eighties with the creation of PROCEL, the National Electricity Conservation Program, in practice its overall performance to control and plan electricity demand has been modest and suffered discontinuities during the following decades. This was especially aggravated in the early nineties when the country started its power sector reform implementing changes in the management, organization, ownership and decision- making of its electricity sector. Privatization was one of the initial steps of the process which aimed to attract private investments and create competition within the industry. Nevertheless, new charges to electricity customers were created in order to secure funds for energy efficiency activities during this period. The main motivation was to ensure provisions for energy efficiency as privatization progressed and address the lack of interest of utilities in energy efficiency activities. The main objective of the present paper is to analyze existing incentives and disincentives for utility-driven DSM programs as results from regulations and market signals. In order to do that it is presented a brief historical overview of the legislation and related regulation that was established to provide support to energy efficiency. The main current laws, decrees and regulation are discussed in more details. Examples of utilities’ programs are presented to illustrate how utilities perceive their interest in EE and allocated funds to the projects. In the concluding section the main problems regarding active engagement of utilities in EE programs. 2. The legislation and regulation on Energy Efficiency 2.1. Evolution (1998-2007) Efforts to secure funds and activities in EE started in a more systematic way in 1998 when the regulator ANEEL established mandatory investments to privatized utilities. Table 1 presents the main Laws, Presidential Decrees and regulations that set the levels of compulsory investments in EE and R&D done by utilities. Several changes occurred not only regarding the amount of funds destined to EE utilities’ projects but also how these resources should be spent by utilities (Figure 1). These later have been subjected to ANEEL’s regulations and are set either by Resolutions or by Guidelines (Manuals) for EE program design and that have to be followed by the regulated electricity distribution utilities. In 1998 the regulatory agency ANEEL defined the amount of annual investment, procedures for submission, approval and verification of privatized utilities’ energy efficiency programs. Since then, ANEEL revises annually the criteria for approving energy efficiency, which are conceived and implemented by utilities. It was established that 1% of the annual net revenues of the distribution utilities had to the invested in annual programs, both for energy efficiency 2
  • 3. and energy R&D. It is important to observe that these funds are collected from electricity customers1 and do not affect utilities profits, this will be further discussed in section 3. In year 2000 the Bill 9.991/00 approved by the National Congress made explicit provisions for a public benefit fund called CTEnerg, a fund managed by an appointed Board of 9 representatives from the Ministries of Science and Technology, Energy and Mines, Public Research Agencies, the Academia and Private sector. This Bill allocates part of the 1% annual utilities’ revenues for CTEnerg and other part remains within utilities (generation, transmission and distribution), being spent in efficiency and R&D programs (Table 1). CTEnerg has the mandate to allocate investments in “public interest R&D and EE” projects. Up to now almost all of its investments have been to energy R&D, and very little to EE (about 5% only). The types of investments related to EE have been directed towards training, and the upgrade of several national metrology laboratories, that could offer support for testing appliances and energy consuming equipment. Only distribution utilities are responsible for the design and implementation of energy efficiency programs2. These programs up to year 2007 had to be previously submitted to the regulator, and upon approval, implemented under the Regulator’s supervision. Bill 9.991/00 extended the 1% obligation to transmission and generating companies (only investments in energy R&D programs) and included private and state-owned companies. This Bill also established that only end-use EE programs would be considered for investments. Changes were introduced in Bill 9.991 through Bill 10. 10.8483, decree 5.879 and finally Bill 11.465, which extended the allocation of 0.50% of annual utilities revenues up to 2010 (Bill 9.991 stated a reduction to 0.25% after 2006). During 1998-2000 part of the regulated investments could be used in supply-side efficiency programs. Since utilities were responsible for the selection of programs, their design and implementation, a significant amount was used to reduce utility’s energy losses, including commercial losses during this period4. Bill 9.991/00 determined that only end-use utility’s programs should be funded out of the wirecharge, since it was understood then that supply- side investment, i.e. improvements in energy efficiency within the utility premises, or its distribution system, should be considered as part of their business strategy to maximize profits. Initially, marketing was also another area that attracted utilities’ investments until year 2000, after that this type of projects has not been allowed as part of the regulated energy-efficiency programs. 1 In this paper we will refer to this tax as wirecharge. 2 Funds collected by Generating and Transmission companies are destined to regulated R&D programs supervised by ANEEL and another part is allocated to CTEnerg (Table 1). 3 It is important to register that during the discussion of this Bill in the Congress, initial drafts proposed drastic reduction of the funds to EE and R&D. The approval of this Bill implied in a final reduction of 20% of the funds originally allocated to EE and R&D. 4 Nearly 70% of investments in Utilities’ programs implemented during 1998-99 were destined to supply side efficiency projects, including projects to reduce commercial losses (Jannuzzi, 2000, Jannuzzi, Gadgil et al 1998). 3

An analysis of the several ANEEL’s manuals and Resolution that were conceived during 1998- 2007, illustrated in Figure 1, shows emphasis on guidelines for formal procedures preparing documentation and justification of proposed projects, and less preoccupation with exploring wider technical aspects of energy efficiency5, evaluation and performance of the proposed projects. Over the years, ANEEL has determined compulsory expenditure shares for residential, commercial, industrial programs. This procedure which fixed percentage expenditure shares has to be observed by all utilities (a total of 64) in the country and has not considered local market specific characteristics, missing some opportunities and sometimes forcing expenditure on less cost-effective programs. 2.2. Recent regulatory efforts In year 2007 ANEEL started to implement changes in the way it regulates utilities’ investments in EE programs. Greater effort is being placed on monitoring, evaluation and verification of results. Utilities will be required to present an evaluation plan which will be subject to the regulator’s approval and third party verification. The new rules will give greater flexibility to 5 Some distortions regarding concepts of energy efficiency can be observed in ANEEL rules for approving EE utility programs. For example: projects that consider changes in technology that use solar, natural gas, or other fuel replacing electricity-based technologies are not permitted. The replacement of electric residential showers (chuveiros) was only permitted after 2002 to be included in the utility EE annual program. 4

  • 7. 3. The persistent disincentive: lost revenues However, up to now ANEEL has not addressed the main utility disincentive: the lost revenues resulting from energy efficiency programs. This affects not only private, but also the few remaining public utilities6. This issue has not yet being considered during the latest revisions of the EE program discussed during the year 2007. The key factors affecting their motivation for engaging in energy efficiency programs can be summarized as: (a) concessions are owned by profit-oriented corporations (more than 80% of electricity is sold by private companies); (b) they sell electricity at a given fixed tariff which is revised each 5 years and has annual adjustments for inflation. The current tariff system in Brazil is a mix of price-cap and revenue-cap regulation. Every five years a tariff revision is performed for each utility consisting of an estimated stream flow of revenues (revenue-cap) and a fixed tariff (price-cap) is assigned to cover the projected expenses, productivity gains and margin for profits. Within the five-year period, tariffs are corrected by inflation indices annually. Since the tariff is fixed, the only way for utilities to increase their profits is to increase their sales (i.e. more kWh sold). Utilities only have interest in EE in very specific cases, when they perceive a direct benefit to them: reduction of commercial losses, investments in less profitable markets in order to meet the demand of other segments without new investments in the distribution sector, etc. The current formula used for tariff revisions is composed by 3 factors that include the variation of costs incurred by the distribution utility: A+B+X Where  A is the component that includes costs that are passed directly to consumers, this factor includes transmission and energy purchases from generators, several taxes collected by the government through the utility Bill, including the investments in energy efficiency (and R&D as well). The component A includes represents about 75% of the distributing utilities revenues. These costs are not controllable by distributing utilities.  B is the component that includes all operational, depreciation of utilities’ assets and the permitted utility’s profit margin. This cost component can be managed by the utility and represents about 25% of its revenues.  The factor X allows for adjustments to compensate gains in productivity levels or compensate losses. Its value is set by ANEEL7. 6 In particular those state companies that are candidates for being privatized and need to keep their economic performance in order to be better evaluated by potential buyers. Most public owned utilities have private shareholders and bonds in stock markets. 7 Perhaps, eventual gains or losses accruing from a CDM project can be included in this factor, if the regulator permits. 7
  • 8. This procedure for tariff revision gives incentives for utilities to demonstrate the need for greater investments increasing the component B of the above formula. The utility that implements good EE programs and therefore reduces the need to expand its distribution system (B is lower) is penalized twice: it will have smaller sales and will be given a lower tariff as compared to another utility which does not implements good EE programs. It is important to note that the funds for EE are collected from electricity consumers as a wirecharge and are not part of utilities’ costs (which are considered under component B of the formula), i.e. utilities design and implement EE programs with their customers’ funds. This fact explains the logic behind most of programs proposed and implemented by the Brazilian utilities. In the next section we try to characterize the major programs that have being implemented to illustrate their preferences for EE programs with less impact on total revenues. 4. Characteristics of energy efficiency investments done by utilities: an overview of past investments 4.1. The Brazilian electricity sector and investments in EE The Brazilian electricity sector has approximately 100 GW of installed capacity, 76.53% of this is hydroelectric and 21.22% thermoelectric. About 187 million consumers were responsible for 390 TWh in 2006 (BEN, 2008). Since 2001 more than 80% of the electricity is sold through private distribution utilities. This contrasts with the situation on the generation side, which is dominated by state-owned companies, responsible for generating 377.7 TWh, about 90% of electricity production in 2006 (BEN, 2008). The average annual percentage growth in electricity demand during 1990-2000 was 4.1%, dropping sharply by -6.6% in 2001 due to the power crisis and rationing which lasted from June 2001 through February 2002. Electricity growth during 2002-2006 was approximately 4.7% per year, indicating a recuperation of economic activity after the crisis. Electricity sales measured in current dollars, using data from total electricity consumption and national yearly average tariffs, shows that the total has been stable in recent years around US$ 15 billion per year up to 2003. However, due to tariff increases allowed by the regulator during 2004, partly to compensate utility revenues losses during the power crisis, total sales can be estimated to have reached approximately US$ 29 billion in 20068, therefore about US$ 145 million is invested annually in EE utility’s programs. The regulation introduced since 1998 increased several times the amount of investments in energy efficiency traditionally done by PROCEL, in year 2000 for example, regulated investments were nearly 6 times higher than PROCEL’s expenditures. Even with changes in the legislation that has reduced the percentage of sales revenues dedicated to efficiency programs regulated investments are several times higher than the amounts previously invested by PROCEL. 8 This refers to revenues from distribution utilities. 8
  • 9. 4.2. The disconnection of utilities’ EE programs and the electricity market Seven utilities9 alone were responsible for more than 70% of the total investments made in EE programs during 2003-04. The remaining 57 utilities located in more dispersed areas of the country have smaller programs and probably higher costs associated with their implementation and face different market conditions to exploit energy efficiency potentials. The regulator has not yet considered in any significant way different approaches to address the differences between utilities.

However, improvements in public illumination systems (mostly changing incandescent lamps for mercury vapor and 10
  • 11. mercury for sodium high pressure lamps) have represented almost half of the investments in end-use programs. These have been the most cost-effective investments for utilities so far and convenient applications. The predominance of public lighting can be better understood when we consider the government program RELUZ administered by PROCEL and EletrobrĂĄs. This program started in 2000. RELUZ can finance 75% of the investment in of new public lighting systems at very subsidized rates of interest.10 The financing is via the utilities. The “1% obligation” funds can be used to provide the remaining 25% share, but the RELUZ funds can be counted towards the fulfillment of the “1% obligation. Other reasons also explain the preference for public lighting programs:  Municipalities pay a relatively low tariff for public lighting, despite its impact on peak load demand and their often poor payment history. From the utilities’ perspective, investing in public lighting EE has been a way to minimize losses from their sales to municipalities, while at the same time taking advantage of the RELUZ.  Since 2002, the minimum cost-benefit ratio required for approval is >15% higher than for all other types of projects.  As shown below, public lighting projects are substantially larger than in other sectors, which may be attractive from an administrative point of view. Initially, marketing was also another area that attracted utilities’ investments until year 2000, after that this type of projects has not been allowed as part of the regulated energy-efficiency programs. 4.3. Low income EE programs Since year 2005 regulation required that at least 50% of total investments by utility should be in low income households programs and for most utilities this has been the main focus of their programs since then. Table 2 shows the allocation of investments during 2005-2007, as it can be seen the average value (more than 60%) higher than the required minimum indicates that utilities have interest in these programs. 10 The interest rate and payment conditions are very favorable, considering existing market conditions in Brazil (5% interest/ year), while rates for BNDES loans are ~15%. 11

Note: * Partial results. The types of low income programs implemented by utilities in low income households are: replacement of incandescent light bulbs for CFLs and replacement of refrigerators, improvements in internal wiring, solar water heaters and regularization of connections (Table 3).

By reducing their electricity bills and improving their connections there is greater chance of reducing the losses in sales. 4.4. Some economic indicators of utilities’ EE projects From 2001 a cost-benefit ratio of 0.85 was required in order to approve EE projects. That was the first time an economic parameter was required for the ex-ante evaluation of programs submitted to ANEEL. This cost-benefit ratio is an ex-ante indicator that considers the estimated annual savings accruing from a specific project over the annual cost of the project (capital costs are annualized and O&M annual costs are included). It was also required that each project have targets that could be quantified and verified. The initial ideas was to create an indicator that permitted a better screening of potential projects, ensuring some measure of comparison 12
  • 13. between similar projects from different utilities. In 2002 Public Lighting projects could yield a C/B ratio of 1.0. Table 4 presents some examples of C/B ratios and related calculations of cost of saved electricity ($/kWh) and avoided demand ($/kW). These examples show that for similar values of C/B ratios different values for the cost of conserved electricity (CCE) and avoided capacity. All listed programs had their cost of saved electricity higher than the costs of electricity sold in the spot market during the year 200311. Table 4: Comparison between costs of saved electricity (R$/kWh) and avoided capacity (R$/kW) (sample of projects from year 2003) C/B ratio Cost of saved energy (CCE) Cost of saved capacity (CEP) Sector Utility R$/MWh R$/kW 0,24 R$ 50 R$ 482 Commerce and services CEMIG 0,25 R$ 64 R$ 215 Public buildings COPEL 0,42 R$ 71 R$ 697 Industry CEMIG 0,44 R$ 146 R$ 395 Public buildings COPEL 0,45 R$ 80 R$ 688 Industry CEMIG 0,47 R$ 76 R$ 980 Commerce and services COPEL 0,49 R$ 95 R$ 597 Commerce and services COPEL 0,51 R$ 102 R$ 453 Industry CEMIG 0,51 R$ 145 R$ 392 Public buildings COPEL 0,60 R$ 160 R$ 489 Public buildings COPEL 0,61 R$ 106 R$ 649 Industry CEMIG 0,67 R$ 133 R$ 608 Public services CEMIG 0,82 R$ 124 R$ 1.126 Industry CEMIG 0,92 R$ 303 R$ 1.327 Public lighting CEMIG Data collected from the approved utilitiesÂŽ annual plans (ANEEL, 2005) suggests that the cost- effectiveness of EE programs may vary greatly due to the significant differences of scale (Table 4). Even if we compare projects under the same category we note large differences in expenditure. For instance, utilities’ public building EE projects vary from R$ 1,646 to R$ 3 million, while public lighting programs range from R$ 32,000 to R$ 20 million (Table 5). The expenditure patterns of utilities’ EE programs are varied. The investment costs per project 11 The spot electricity prices in Brazil varied from 6.43 R$/MWh to 49.41 R$/MWh during year 2003 (CĂąmara de Comercialização de Energia ElĂ©trica. http://www.ccee.org.br. Access 6/ Feb/2008) 13
  • 14. range from a few thousand R$ to almost R$ 20 million. The analysis of EE projects by major categories indicates the predominance of public lighting as the largest projects implemented by utilities, with the average project costing almost 10 times more than the projects implemented in public buildings and more than 3 times the average cost of industrial sector EE projects. Table 5: Energy Efficiency projects basic statistics for main categories (cycle 2003- 2004) Public Industrial Total EE Public lighting Buildings sector projects Total number of projects 162 64 48 396 Average expenditure (R$S/project) 196,212 507,311 1,911,494 557,735 Minimum (R$/project) 1,646 4,994 32,649 1,646 Maximum (R$/project) 3,000,000 3,783,672 20,350,001 20,350,001 Total expenditure (R$) 31,786,429 32,467,879 91,751,692 220,863,131 Source: ANEEL (2005). 5. The incentives It is important to highlight that some utilities (only the large ones, such as Eletropaulo-AES, CEMIG, mainly) have started to see business opportunities with EE in their concession areas. These utilities have created their own ESCOs, and as an unregulated activity (different from the electricity sector) and they can operate in other concession areas and capture economic returns on their investments in energy efficiency12 . They operate in markets with large and sophisticated costumers and are able to develop business proposals improving the energy use and also sell other services and equipments. Many utilities have also used EE programs as part of their strategies to retain their large (and non-captive) consumers13. 6. Concluding remarks We consider that there are still strong disincentives for utilities to undertake EE programs as part of their business strategies. The “lost revenues” issue is the main barrier for utilities to approach end-use efficiency. The almost 10 years of existing compulsory utility EE programs have shown that they always seek ways to invest in markets that represent lower revenues, or large commercial losses. Even the cost effectiveness of many of these programs can be shown to be less attractive than purchasing electricity on the spot market or the marginal cost of electricity production. 12 ANEEL started to introduce accounting procedures to ensure that economic benefits from investments done under the 1% obligation are also returned to consumers, at the time utilities’ tariffs are reviewed. 13 Non-captive consumers are the ones with demand greater than 3 MW and can choose their electricity provider. 14
  • 15. Also, the lack of more comprehensive studies on the existing potential for the introduction of energy efficiency measures in the Brazilian market together with better program evaluation practices have, in our view, limited the benefits accruing from potential electrical system-wide impacts from these programs. ANEEL’s role as the supervisor of utilities programs could be further enhanced with more coordination amongst individual programs and better knowledge of EE potentials. ANEEL’s Resolutions are powerful means to direct utilities’ investments to certain desired energy programs and they can be implemented speedly dependending on the regulator interpretation of the current legislation and after the process of public consultation. We understand that the factor X in the current Tariff revision formula scheme is one plausible mechanism to reward companies that are implementing good EE programs, and also compensate those that report losses in sales revenues. 7.
