California ISO's Board Approves MRTU Design

LCG, October 20, 2005--The California Independent System Operator (California ISO) announced yesterday that its Board of Governors unanimously approved the final elements of the Market Redesign and Technology Upgrade (MRTU).

The MRTU is intended 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 in nature to those currently operating in the northeastern United States.

The conceptual design of the MRTU was previously approved by the Board and the Federal Energy Regulatory Commission (FERC). A stakeholder review and development process has since occurred to develop more detailed market design and rules. With the latest Board approval, the California ISO plans to further refine of the details and to file the FERC tariff in late November. System trials and training are planned to occur in 2006, with the final implementation planned for February 2007.
