The Western Energy Imbalance Market approved two CAISO measures and endorsed a third to improve reliability, mitigate capacity shortfalls.

El Paso Electric, a utility that serves more than 400,000 customers in Texas and New Mexico, plans to join CAISO’s Western Energy Imbalance Market in 2023.

The Western EIM Governing Body discussed CAISO’s summer energy shortfalls, pondering how the EIM could better serve participants during system stress.

BPA acting administrator and CEO John Hairston will officially assume the top job at the federal power marketing agency, the DOE said.

CAISO’s top priority in 2021 will be making sure there is enough generating capacity for summer after last year’s shortfalls.

Benefits for participants in CAISO’s EIM surged past $119 million in the third quarter, a record amount driven by heat waves in Aug. and Sept.

The creation of a Western RTO could save the region more than $1.2 billion annually in electric costs, according to a new study.

CAISO launched a two-part initiative Wednesday that would alter how Western Energy Imbalance Market participants submit their base schedules.

CAISO's outgoing and incoming CEOs answered stakeholder questions in a roundtable discussion hosted by the EIM’s Regional Issues Forum.

EIM stakeholders broadly support a proposal that would expand the Governing Body’s approval authority and grant it a “more collaborative” relationship with CAISO’s board.
