Peak Load Are Growing Faster Than

Average Energy Use

* Between 1995 and 1999 WSCC Peak Loads increased

by nearly 12,000 MW (nearly 10%/year) while energy

used only increased 65,000 GWH (about 2.3%/year)

a The most rapid growth in the WSCC between 1995 and

1999 occurred in the Arizona, New Mexico and Southern

Nevada area:

-Area accounted for only 12% of summer peak loads

in 1995

-Area accounted for 47% of the growth between 1995

and 1999

Summer Peak Load Growth in the NW

Power Pool Reduces Hydro Exports

* The NW Power Pool is a winter peaking area, however

between 1995 and 1999 its summer peak grew by 3,900

MW

* Increases in NW Power Pool summer peaking demand

will gradually eliminate its ability to export lower cost

hydro-electricity to other areas in the WSCC.

* This is expected to increase on peak electricity prices

in these other areas.

- On two days with nearly identical peak loads, CA

prices in 2000 hit $750/MWH (price cap) vs just over

$150/MWH in 1999

- NWPP exports were 3000 MW less in 2000 than 1999

Implications for Air Conditioning Rule

Making

* Summer peaking uses of electricity (i.e. air

conditioning) are expected to drive retail electricity prices upward throughout the West due to low "load

factors"

a Either average retail electricity rates must increase or

greater "seasonality" in retail rates must occur to cover

cost

* Recommendations

- DOE should adjust 1997 average energy prices to

reflect summer/winter differentials in wholesale

electric prices

- EER requirement is critically needed & justified
