May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Introduction to Electricity Part II: The Changing Electricity Industry

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program The Electricity Industry Electricity systems worldwide are changing for one or more reasons: Technological advances Financial/management crisis/inadequate investment Public opposition Consumer demand for lower costs, better service Political cronyism...

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program The Changing Industry Structure Vertically Integrated Model – generation, transmission and distribution controlled by one or several utilities (usually state owned). Government grants utility monopoly power Regulated by government Centralized planning, operation Government-guaranteed investment/regulator ensures cost recovery from consumers Captive consumers/ratepayers Key problems: high cost AND/OR low quality service

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Single Buyer Model UTILITY National Transmission System Owner/Operator State Owned Power Plants Private – Independent Power Producers IPP Industrial/Rural Cogeneration Government Regulator Small/Renewable Power Producers UTILITY Distribution Municipal or Provincial Consumers/ Small Producers

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program The Changing Electric Industry Structure Single Buyer Model Private and state producers selling to central utility/no competition Centralized planning, operation Transmission centrally owned/operated by central utility Large industrial consumers can buy electricity from central utility or direct from private power producers or self-generate Key Problems: Small consumers still captive/no choice Government still conflicted as owner/regulator Central utility can shut out competitors NOTE: World Bank promotes this model in China, Thailand, Vietnam but its own experts admit it encourages over-investment, corruption, high- cost power purchase deals, poor regulation.

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program The Changing Electricity Industry Market-Oriented Restructuring: Privatization and unbundling of Generation, Transmission, Distribution New competitive procedures for power producers New forms of regulation

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Restructuring Theory/Objectives To raise capital To improve regulation To eliminate government/investor conflict of interest To boost economic efficiency To lower rates and improve service To give producers and consumers competitive choices.

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program General components of market-oriented restructuring WHICH ONES CAN YOU IDENTIFY IN YOUR COUNTRY? CAN YOU SAY WHICH TRENDS ARE POSITIVE FOR CONSUMERS? WHY? 1. Unbundling of generation, transmission, and distribution into separate businesses. 2. Open transmission access. 3. Operation of the transmission system assigned to a few distinct organizations. 4. Creation of a new class of non-regulated generators. 5. Formation of new organizations for dispatch of all generation. 6 Competition in power production with dispatch based on quoted prices. 7Construction of many gas-fired plants by independent owners. 8. Payments for some power production based on ‘market clearing’ price, which is the highest of any accepted bid prices. 9. Retail “wheeling” increasing in stages to smaller and smaller size customers (unsuccessful in many places). 11. No central planning, no government guarantees to purchasers. 12. Hedging contracts to guarantee prices to power purchasers in a volatile market.

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Distribution companies Can buy power from supplier of their choice or from market exchange Consumers can sell direct to distribution companies

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Old vs New utility regulation Old regulated utilities make money building new power supply projects, bigger=more revenue/profit New regulated utilities help customers save energy; help customers buy less of utility product: electricity!

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program New utility regulation Utilities earn a return for investment in saving energy that is equivalent to what they earn from investments in new power supply capacity. More state funding for energy efficiency improvements across sectors Governments allow utilities to collect money from ratepayers to pay for energy efficiency projects State-led emission reduction targets

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Examples California – Pacific Gas & Electric Co. helping Subway (30,000 restaurants) install energy-efficient breadbaking ovens Working with wineries – 2,600 wineries consume one-third of energy consumed by food processors In California, state law requires utilities to meet new supply needs first through energy efficiency then renewables, then building new (conventional) power plants Utilities in California – rate structure rewards them for cutting electricity use, not for pushing energy sales

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program New Utility Business - Conservation Iowa Power & Light – advising pig farmers on energy-efficient lighting and ventilation – energy-efficient lighting can save $10,000 a year in electricity cost Pinnacle West Capital – Arizona utility – is working with district school board to install new efficient heating and cooling systems in schools, adding solar to school rooftops

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Consumers as Producers Homeowners install ~ 10kW solar system Send surplus to the grid and get paid by utility Utilities (Sacramento Municipal Utility) willing to pay retail rate because solar systems produce power during peak (mid-day) hours, improve performance and reliability of grid. 19 states give homeowners credit to reduce their bill, but not cash 10 states require utilities to pay homeowners wholesale rate for surplus solar

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Which policy leads to most solar at lower cost? Still too early to tell Critics say solar homeowners are getting a free ride: They get a cash rebate for installing system, which comes from ratepayers They get credit at retail rate even though they don’t pay any transmission maintenance charge Interconnection charge is waived while other producers have to pay >> critics say unfair subsidy Critics say paying people for “surplus” will encourage larger-than-necessary systems (See Thai solar producers)

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program Examples Duke Energy (North Carolina) – helping Budweiser make its beer chillers more efficient, saving Bud big $ Duke looking to regulator to get special incentives to expand energy efficiency business

May 11 – 30, 2009Mekong Energy & Ecology Network Training Program What role environmental/community advocates in the Mekong region? System is changing, for better or worse Know your power Bright ideas vs dim bulb policies Define public interest Transparency Accountability Participation Democratize the grid!
