This report documents an ex post and ex ante load impact evaluation for the Demand Bidding Program (“DBP”) administered by two of California’s large investor-owned utilities in 2009. The evaluation first reports on the estimation of DBP load impacts that occurred on the event days called during the 2009 program year at Pacific Gas and Electric Company (“PG&E”) and Southern California Edison (“SCE”). Load impact results are reported at the program level, by industry type, and by local capacity area. Ex ante forecasts of load impacts are then reported based on enrollment forecasts provided by the utilities and a characterization of the per-customer load impacts observed in 2009.

A baseline analysis was also conducted to compare the program’s baseline method, the 3-in-10 method, to baselines implied by the estimated regression equations and to the alternatives of unadjusted and adjusted 10-in-10 methods.
