Western commissioners’ letter signals positive collaboration around regionalization to deliver reliable, affordable energy to the West and calls for action on Western RTO development 

SACRAMENTO, CA -  Today, commissioners from Arizona, California, New Mexico, Oregon, and Washington sent a letter to the leadership of the Western Interstate Energy Board (WIEB) and the Committee on Regional Electric Power Cooperation (CREPC) outlining their intent to work collectively toward a West-wide Regional Transmission Organization (RTO). The letter represents a breakthrough in efforts to advance the regions’ energy landscape and is key to creating a market that fosters collaboration, improved reliability, and economic growth. Advanced Energy United, the national clean business association, applauded the effort and released the following statement:

RTO Insider examines the possibility of a Western RTO, citing Advanced Energy United's support for this region's hopes to develop a west-wide wholesale market.

PORTLAND, Ore. — The competition for organized markets in the West grew Friday as the Bonneville Power Administration launched a process to choose between day-ahead markets proposed by CAISO and SPP and regulators from five Western states urged the establishment of a new, independent RTO covering the entire West.

“This group proposes the creation of an entity that could serve as a means for delivering a market that includes all states in the Western Interconnection, including California, with independent governance,” regulators from Arizona, California, New Mexico, Oregon and Washington wrote to the chairs of the Western Interstate Energy Board (WIEB) and the Committee on Regional Electric Power Cooperation (CREPC).

The entity “could provide a full range of regional transmission operator services, utilizing a contract for services” with CAISO including eventual “assumption” of CAISO’s proposed Extended Day Ahead Market (EDAM) and its real-time Western Energy Imbalance Market (WEIM).

WASHINGTON, DC, May 17, 2023 — Today the North American Electric Reliability Corporation (NERC) released its annual summer reliability assessment warning Western states that they are in for another summer of elevated risk of blackouts due to extreme heat in 2023. NERC issued a similar warning last May, before record heat waves strained energy supplies in Arizona, California, Colorado, Montana, Nevada, Utah, Wyoming, and the Pacific Northwest in September.

Assembly Bill 538 "jumpstarts" conversation around regional grid collaboration, with the potential to save hundreds of millions in energy costs

SACRAMENTO, Calif. – Introduced by Assemblymember Chris Holden (AD41), Assembly Bill 538 would create a structure that would allow the California Independent System Operation (CAISO) to integrate into a broader, independent regional transmission operator (RTO). A 2022 economic development study commissioned by Advanced Energy United and conducted by Energy Strategies found that a transition like the one proposed in AB 538 could create over 138,000 jobs and save ratepayers $538 million per year in energy costs.

Colorado Governor Jared Polis: “We are continuing to save people money, lower energy bills, and bring more good-paying jobs to Coloradans, and this new report confirms that a Western market advances our bold work achieving these goals. Colorado has committed to join a Western market by 2030, and we look forward to continuing to work with leaders across the region to lower energy costs while making progress towards our goal of 100% renewable energy by 2040."

Released last week by Advanced Energy Economy (AEE), the Western RTO Economic Impact Study was prepared by Energy Strategies and Peterson & Associates. It draws on analysis Energy Strategies performed for a state-led study published last year to quantify the electricity system benefits of a Western RTO.

This week, national business group Advanced Energy Economy (AEE) released new research into the economic development potential of establishing a regional transmission organization (RTO) to operate the power grid for Western states. The report, conducted by independent consulting firm Energy Strategies, finds that establishing an RTO for Western states would create as many as 657,000 permanent, high-paying jobs in the West. If you want to learn more, watch the press briefing here.
