California ISO Sets New Implementation Date for the Market Redesign

LCG, January 26, 2006--The California Independent System Operator (California ISO) announced yesterday that it will defer the implementation date for its Market Redesign and Technology Upgrade (MRTU) program. The implementation date is being pushed back from February 1, 2007 to November 1, 2007.

Drivers of the delay include software revisions, such as those necessary to incorporate new resource adequacy rules set by the California Public Utilities Commission, and a new assessment of the effectiveness of the program's project management. The budget for the program has also been increased by approximately $30 million.

The objective of the MRTU program is to improve the electricity market structure in California to enable an efficient, competitive, robust market to evolve. The primary elements of the MRTU include the Integrated Forward Market, Full Network Model, and Locational Marginal Pricing (LMP). Implementation of the MRTU will generally create day-ahead and real-time markets similar to those currently operating in the northeastern United States. In conjunction with the market design changes, the MTRU includes a major overhaul of computer systems and infrastructure. The revised budget for the MRTU program is now $170 million.
