  3. Structure of supply (35-45%) • Steep supply curve • Highly dependent on gas (with no alternative) • High gas prices and costs for environmental externalities • Large amounts of "unreliable" capacity (e.g., hydro, imports) • Market dynamics (55-65%) • Capacity additions not timely • Demand unresponsive to price • Bidding rules/procurement requirements magnified generator market power • Price caps distorted market signals and made matters worse LAN020315003-24972-853 MICROECONOMIC ROOTS OF THE CRISIS

  4. Gas fired • Summer loads • Winter loads LAN020315003-24972-853 PRICE IS VERY SENSITIVE TO SMALL CHANGES IN DEMAND California power and load duration cost curves 2000 • Marginal generation costs • $/MWh • Actual load • Hours • 900 400 4,000 350 3,500 300 3,000 250 2,500 200 2,000 150 1,500 100 1,000 50 500 0 0 0 15,000 30,000 45,000 • CaISO generation capacity • MW

  6. Still reflects tight supply at wellabove $100/MWh • 2001 Q1/Q2 would represent additional potential savings – almost 16GWh of blackouts prevented • $0.2 billion-0.6 billion in economic costs avoided LAN020315003-24972-853 ESTIMATED TOTAL OPPORTUNITY COST – CALIFORNIA 2000 • ESTIMATE $ Billions • Cal PX power spend • DSM/RTP savings opportunity • Net power spend with DSM/RTP in place

  8. LAN020315003-24972-853 NATIONAL ECONOMIC BENEFITS FROM DYNAMIC PRICING IN MASS MARKET • ESTIMATE $ Billions Demand Curve shifts – lower prices for everyone • 12 • 10 Direct benefit from curtailing or shifting loads • 2 • Total • Collective benefit • Individually measurable benefit Source: McKinsey analysis

  9. ~250 "peaker" plants not built • Power infrastructure for peaks reduced by 31,000 MW, saving $16 billion in capital costs (one-time) • 31,000 tons of NOx not emitted (per annum) • Reduction in water used for hydro electric generation • Gas demand reduced by 680 bcf/year • Gas transmission reduced by 2 bcf/day • Other environmental benefits, e.g., • Cleaner water • Thermal pollution • Hydro power impact on ecosystems • Enough saved electricity to supply 7 million new homes annually • Significant benefits for avoiding blackouts (lost productivity) • Other system benefits • Avoided transmission and distribution investment • Reduced meter reading costs LAN020315003-24972-853 INDIRECT BENEFITS OF BROADLY DEPLOYED NATIONAL DYNAMIC PRICING SOLUTION • ESTIMATE Note: Assumes 125 MW peaking plant, $500/kW capital cost, 25% load factor, 10,000 heatrate, 0.9 lb NOx/MWh Source: Department of Energy; EIA Power Annual Volume II; BAEF Report; EIA RECS 1997; McKinsey analysis

  10. LAN020315003-24972-853 NEED FOR AN INSTITUTIONAL SOLUTION • "Free rider" challenge • 80% of benefit stems from collective actions • 50% plus adoption required • Voluntary program will not work • Capital intensive – estimated at up to $1-3 billion • Utilities must be involved • Metering savings alone will not justify investment • Some form of guaranteed return necessary • Comes down to ensuring a public good
