Electric Sector Characteristics
7
Large capacity dams, in 7 basins with different hydrologic regimes Generations in the different basins are linked through huge transmission lines, in some cases longer than 1,000 km There were 91 hydroelectric plants and more than 69,000 Km of transmission lines (Dec.2000) These features make the Brazilian system one of the world’s biggest inter-linked systems I N T E R L I G A Ç Ã O N O R T E - S U L Electric Sector Characteristics

2001 Crisis Immediate cause: extremely unfavorable hydrology in 2001 –San Francisco river: worst year since 1930 –Grande River: 4th worst wet period since 1930 Other causes: pace of implementation of the new model, regulatory issues, miscoordination

Reservoirs Levels Southeast + Center West
11
Energy Crisis Management Energy Generation Situation By Then Minimum requirement of more than 3.000 MW/year Hydro Plants were responsible for 95% of the overall generation. Very low reservoirs levels. Thermal Expansion Plan not implemented due to weak market incentives. Transmission Insufficient to handle all the needs – investments planned not implemented in time. Temporary Measures ResolutionsDecrees Energy Crisis Management Committee was created Consumption Reduction Emergency Program and Electric Energy Strategic Emergency Program were implemented
12
The Electric Energy Crisis Management Committee Action Plan
13
Action Plan At the crisis onset, a presidential decision created a top level committee: The Electric Energy Crisis Management Committee (CGE) This Committee proposed an Plan Action based on five points
14
1) Emergency Program for the Energy Consumption Reduction 2) Structural program to increase the energy supply 3) Emergency program to temporarily increase the energy supply 4) Energy Efficiency 5) Electric Sector Model Revitalization Action Plan
15
Main Objectives To avoid the imposition of unnecessary sacrifices on the population To maintain minimum safety levels in the reservoirs These objectives were achieved due to extraordinary popular support for the plan 1) Emergency Program for the Energy Consumption Reduction
16
Mandatory average consumption reduction for almost 40 million units connected in the Southeast and Northeast Regions, involving over 140 million people (80% of total country population) Goals for each consumer were established based on past 3 months consumption Reduction goals were about 20% and specific guidelines were defined for specific sectors and special situations The responsibility for reduction was transferred from the Utilities to the clients and this was implemented in such a way to promote more efficient energy usage habits New connections were suspended in the beginning of the Plan implementation Electric Companies improved their Energy Efficiency Programs (which were already obligation before the crisis) and started distributing electronic bulbs for low income houses, helping the families to meet the goals Rationing Law Basic Guidelines
17
Low VoltageMedium and High Voltages < 2,5 MW Medium and High Voltages > 2,5 MW Consum. < goal Bonus kWh credit Consum. > goal Exceeding consumption by $ MAE – spot prices Compensa tion Bilateral Trans. (same econ group / same prod proccess) Bilateral Trans. / auction certificates Service Cut 1 day for each 3% above goal Rationing Law Basic Guidelines
18
The program started in June with no deadline to be suspended The program was at the same time simple and complex, rigid and flexible – as time passed, it managed to handle exceptions in a wise way, changing rules for specific situations – 70 resolutions plus 186 decisions The basis were simple and visible – limit consumption, teach how to reduce, give price signals The results were measured everyday by the system load and reservoirs levels If the plan had no effect, there were a Plan B that included holidays on Fridays or selective shifts load shedding Successful Rationing Implementation
19
For the clients – a change of habits There was a positive side of the crisis: as each consumer were responsible for it's own usage reduction, common people learned about how to use better their appliances and followed up the bills and the numbers; People were surprised about how the monthly bills reflected the past inefficient use of electricity - reduction was kept after rationing; General Awareness about energy and water being increasingly scarce and more expensive - awareness about related environment issues
20
Rationing Program Operational Impact for Dist Cos. New Rules issued everyday - must be immediately implemented Many Companies implemented call centers fully devoted to the Rationing Program Dramatic increase in Call Center and walk in facilities volume Increase in requests for new meter installations Large number of individual goals and bills revisions requests Disconnections and reconnections for those that exceed quota Large media coverage – Newspapers FrontPage everyday Legal constraints were addressed and didn't impact implementation
21
Energy Rationing: Jun-Dec 2001 (average MW) NORTH Load Reduction over Jul/Aug/Sep 2000 Load Reduction over same period 2000 Load Reduction over initial forecast for 2001 19.0% 18.3% 24.6% SOUTHEAST/MID-WEST Load Reduction over May/Jun/Jul 2000 Load Reduction over same period 2000 Load Reduction over initial forecast for 2001 21.1% 25.3% 18.2% NORTHEAST Load Reduction over May/Jun/Jul 2000 Load Reduction over same period 2000 Load Reduction over initial forecast for 2001 16.4% 20.2% 24.2%
22
Total generation capacity of the inter-linked system in Feb 2002 was 74,000 MW, for an estimated peak demand of: before the crisis 56,000 MW after the crisis 44,000 MW So, Brazilian costumers in general succeeded to significantly improve the energy usage efficiency in a particular way ! Peak Load was also Significantly Reduced with Efficiency
23
Load Evolution (1994-2001) 2001 2000 1999 1998 1997 1996 1995 1994 23,198 25,848 25,560 23,961 23,112 22,086 21,252 20,096 Southeast/Mid-WestAverage MW
24
Load and consumption reduction were taken back to 1997 patterns and just returned to 2001 levels in 2006; The crisis opened discussion for other renewable energy sources implementation like biomass, wind, self production, etc. and investments in distributed generation aiming at energy matrix diversification; The crisis opened the free negotiation market for large consumers Rationing Program Residual Impact

EMERGENCY ELECTRIC ENERGY SUPPLY FOR 2002-2003 Estimated demand for 2002/03 Structural Supply Program 2001/03 Assumptions for hydrology Emergency Supply Needs 2002/03
29
Emergency Supply Guidelines Additional energy supply, on a temporary basis, to work as an “insurance” for the consumer A public energy trader (SPC) - (Brazilian Electric Energy Commercial Company-CBEE), was set up to: Buy energy from independent producers Lease or buy generation equipment Buy rights to consume from larger consumers
30
Contracting Emergency Generation Implemented in 5 months 117 proposals received (>4,000 MW) 2,100 MW selected 1,500 MW NE 600 MW SE average price: 290 R$/MWh 100 R$/MWh fixed price 190 R$/MWh variable price

34
Created by a GCE Resolution Mission: –Correct inadequacies and propose improvements in the power sector model. –Preserve model's fundamentals: Competition in generation and retailing Based on Private investments Independent regulatory body to ensure adequate balance between utilities and consumers and high quality of services Sector Revitalization Committee
35
Prices in the spot market are based on a computational model hydro generators do not manage all of their own risk MAE (wholesale market) functions are mostly administrative (accounting and settlement) Prices in the spot market are very volatile due to hydrological conditions barrier to the entrance of merchant plants long-term bilateral contracts required load’s willingness to contract drives system expansion Contracts require physical backing the desired supply reliability is achieved only when 100% of load is contracted Power Sector Model in Brazil (1 of 2)
36
There were (almost) no free consumer at that time Regulatory Agency used to set limits (Normative Value - VN) on the pass-through of generation prices to captive consumers Difficulties: –no external price reference for VN in Brazil –there were multiples VNs (implicit subsidies for specific types of energy) Existence of public generation companies when Initial Contracts start to phase-out potential for unbalanced competition (e.g. public companies could have taken an aggressive commercialization strategy by “mixing” new energy with existing hydro energy which has already been amortized) Power Sector Model in Brazil (2 of 2)
37
Signed on Dec. 18th, 2001 Solved deadlock and avoided breaking of announced investments Contributed to prevent repetition of events in the near future Avoided financial hardship for generators and distributors alike General Agreement
38
A. Resume market operation B. Reinforce market-based mechanisms C. Ensure adequate expansion of supply D. Monitor supply reliability E. Improve interface between free market and regulated segments F. Stimulate fair competition G. Balance realistic tariffs and consumer benefits H. Improve functioning of institutional agents Revitalization objectives
39
G&D Agreement MAE governance Improve spot price calculation (dispatch model parameters + risk aversion factor) A. Resume Market Operation
40
Introduce price bids for short-term market Prevent potential market power from government-owned generation (discussed next) Stimulate free consumers B. Reinforce market-based mechanisms
41
Proposal for Government-owned generation All energy belonging to these companies will be contracted through public auctions Additional dividends earned by the Federal Government will be used to finance emergency plants, natural gas subsidy, etc. Transparency Interests of shareholders (both Government and minority shareholders) and consumers are protected
42
C. Ensure adequate supply expansion Revise Assured Energies Reinforce minimum bilateral contract requirements Create generation reserve Stimulate peaking capacity expansion Stimulate energy conservation Quicker environmental licensing procedures
43
D. Monitor supply reliability Establish “early warning” procedures with clear responsibilities Ministry of Mining and Energy to supervise long-term equilibrium between supply and demand
44
E. Improve market/regulated sector interface Unify VN values Improve transmission expansion planning methodology Increase the signals embedded in transmission tariffs for different locations
45
F. Stimulate fair competition Proceed with unbundling Stricter limits for cross-ownership and self-dealing Separate tariffs for distribution (“wires business”) Improve tariff revision procedures
46
G. Realistic tariffs and consumer benefits Universal access for electricity Improve mechanisms for alternative energy sources funding Subsidize gas transportation for PPT (Thermal Priority Program) power plants Eliminate cross subsidies Special tariffs for low income consumers
47
H. Improve functioning of institutions MME (Ministry of Mining and Energy) Reorganize ONS (National System Operator) Governance of ONS Improve ONS Grid Procedures Complete ONS dispatch software MAE (Whole Sale Market) Improve MAE rules Improve definition of sub-markets Improve Energy Reallocation Mechanism - MRE
48
General Consequences of the Proposed Measures Reinforcement of model’s fundamentals and market mechanisms Higher government intervention at the regulatory level, not as entrepreneur Rights of private investors were preserved
49
Main Principles: Supply Security Lower Tariffs Social Inclusion Assumptions: Minimize risks; Preserve functions and institutions, improving governance; Improve generation expansion and the integrated management, aiming at supply security increasing; Diversify the energy matrix, considering the complimentary character of different sources; Respect the existing contracts New Electric Sector Institutional Model

Planning and Supply Monitoring Integrated Resources Planning System Expansion Planning Technical and Economic Viability Studies Environment and Social Viability studies Energy Ministry – MME Energy Ministry – MME Supply evaluation Performance Monitoring Expansion Construction Monitoring Social and Environmental follow up Energetic Planning Enterprise - EPE Electric System Monitoring Committee - CMSE New Electric Sector Institutional Model
51
Freely negotiated or bid prices Generation (competitive market) Regulated Market (ACR) Free Market (ACL) Prices resulting from Bids Distribution Co´s Free Clients Brokers Two Energy Contracting Markets: Regulated Market (ACR) – Distribution Companies Free Market (ACL) – Free Clients and self- producers “Efficiency Metabolism” Self-producers New Electric Sector Institutional Model
52
Contracting by Energy type The “new” and the “old” energy Existing Energy Contracting by Bids Periodic Bid at CCEE for 3 to 15 years contracts Initial contracts – 8 years Deliver in the following year (A-1) Large auction in Dec 2004 – many (A-1)
53
Existing Energy Contracting by Bids New Energy Price Cap (R$/MWh) for plants listed by EPE Winner will be the lower price offer for each project Winning Hydro Generator Gerador receives the tarrif offered and follows competing with the other energy offers for the auction 15 to 35 years contracts – usual 30 years for hidros and 15 for thermal 3 and 5 years ahead delivery “botox”(under delayed construction)energy projects were acepted till 2007 The hydro concession is offered to the ACR winners Contracting by Energy type The “new” and the “old” energy
54
ACL – MACRO Environment Free Market Growth What happened ? Offer and Demand unbalance and the free market responded quickly. Market Response: Price 0 2000 4000 6000 8000 10000 12000 dez/99dez/00dez/01dez/02dez/03mai/04dez/04dez/05jun/06 ACL Excess Post-rationing excess Offer increase+ consumption reduction Post-rationing excess Offer increase+ consumption reduction jun/07 Increased reduction with free mkt sales
