Grid’s New Wholesale Market Delayed

By Published On: November 26, 2008

The California Independent System Operator’s wholesale market redesign was delayed once again. The grid operator’s board voted November 24 to postpone the “go live” date from February 1, 2009 to March 1, 2009. Market participants were nonplussed. “We’re close enough, but not quite there,” noted board member Tim Gage. The trading program is set to allow bidding on a day-ahead basis, as well as other features like smoother settlements with market participants. Currently, the grid operator’s wholesale market handles about 2-3 percent of California’s electricity bids and trades. Remaining problems include the real time “test” of the system, which has not yet been executed. In addition, the prices shown in the new market reviews have been questioned, according to Steve Berberich, CAISO vice president of corporate services. In general, market participants reveal they prefer a working market later over one with glitches sooner.. Once the software is deemed usable for the new market, the grid operator has to get approval from the Federal Energy Regulatory Commission before actual launch.
