Electricity and Natural Gas Supply, Reserves, and Resource Adequacy

CMTA Energy Conference

Energy: Growing California’s Economy

William J. KeeseCalifornia Energy CommissionJuly 29, 2004

An Opening Thought…

• Promote energy efficiency

• Diversify portfolio with renewable energy

• Offer consumers energy choices

• Strengthen California’s energy infrastructure

Remember the Loading Order

3

Helping the California Economy:An Energy Report Card (Post Crisis)

• Energy Efficiency– 5000 MW during crisis– About one-third permanent savings– Demand Response programs being developed

• Renewable Energy– Lots of PV– RPS– WREGIS

• Consumer choice– No direct access and some exit fees– Core/noncore structure being addressed

• California’s Energy Infrastructure– New generation and natural gas infrastructure added.– LNG on the horizon?

Resource Adequacy

Definition: “A condition in which sufficient generation and transmission resources exist to cover

load and satisfy reserve requirements”

Outstanding issues:– Tradeable capacity credits– ISO dispatch control over nominated resources

Natural Gas Price Situation (Dollars per MMBtu)

• High natural gas prices continue to be a national problem.

• California natural gas prices have exceeded $5.00 per MMBtu for most of this year.

• California is actually doing better than the rest of the nation. – Main reason: Infrastructure

enhancements and efficient use of storage.

California’s Natural Gas OutlookGeneral Observations

• Current supply/infrastructure is adequate…FOR NOW.

• Prices are higher than desired, but we are positioned to do better than the rest of the nation.

• Demand for natural gas is growing in California despite aggressive energy efficiency programs.

• Additional import capacity is needed to meet future demand.
