The California ISO Targets February 2007 for Final Integration of Market Redesign

LCG, June 29, 2004--The California ISO Board of Governors met on June 24, 2004 and approved the updated market redesign and infrastructure upgrade program, with a scheduled completion date of February 2007. The ISO plans to address reliability and market design improvements, as well as replace aging information and technology systems with new, more reliable systems through one infrastructure upgrade program.

The market redesign, commonly referred to as MD02 (Market Design 2002), will significantly change California's electricity market. The new design is similar to those developed by the ISO's operating in the Northeast and will include locational marginal prices (LMPs), an integrated forward market (IFM) and real-time market, and congestion revenue rights (CRRs).

The system upgrades will include the settlement system and scheduling infrastructure replacement, together with other systems consolidation and integration efforts. According to the ISO, the system upgrades are to replace original systems installed in 1997, and these system upgrades would be necessary regardless of the market redesign effort. The total program costs for the market redesign and technology and infrastructure upgrades, including a $12 million contingency, are estimated by the ISO to be nearly $140 million.
