Energy Curtailment For The California Energy Commission June 27, 2002 Bank of America Energy Curtailment For The California Energy Commission June 27, 2002

California Energy Commission Pilot Test On June 27, 2002, WebGen Systems Intelligent Use of Energy product curtailed 2 Megawatts of power, in 78 Bank of America properties, within the state of California. The total load of the 78 properties was approximately 9 Megawatts The time duration was four hours. The test commenced at 2:00 PM, and completed at 6:00 PM, PDST The following slides display the demand trends for Northern & Southern California, and the aggregate for the pilot test.
