EIA Presents Analysis of California's Solar and Wind Power Curtailment Challenges

LCG, May 29, 2025--The U.S. Energy Information Administration (EIA) released an analysis yesterday showing that the California Independent System Operator (CAISO), the grid operator for most of the state, is increasing its curtailment of the rapidly growing solar- and wind-powered generation facilities in order to balance electricity supply and demand, which is necessary to maintain a stable electric system.

California ISO Announces New "Go-Live" Date for MRTU

LCG, August 23, 2007--The California Independent System Operator (California ISO) yesterday announced a new "go-live" date of March 31, 2008 (for a trade date of April 1, 2008) for the implementation of the Market Redesign and Technology Upgrade (MRTU) program. The prior target was February 2008.

The MRTU is designed to improve the electricity market structure in California so as to enable a more efficient and competitive market to evolve.

Key elements of the MRTU include: a financially binding, day-ahead energy market; models for the California ISO to forecast and identify transmission congestion as a tool in managing congestion; Locational Marginal Pricing (LMP) to provide the proper economic signals to influence new generation and transmission investments; provisions to enhance the development of demand response and renewable resources, and upgrades to the aging ISO computer system.

The California ISO stated that numereous MRTU milestones have already been achieved, such as the launching into production mode the system for Congestion Revenue Rights (CCRs).

The Federal Energy Regulatory Commission (FERC) in September 2006 unanimously approved the MRTU program submitted by the California ISO. At that time, the MRTU was scheduled to be implemented in November 2007.
