Colorado utility Platte River Power Authority is the latest Western utility to express intent to evaluate participation in SPP's RTO West.

SPP and Western entities interested in the RTO’s Markets+ “RTO light” offering continued to inch toward each other during another development session.

SPP’s Western Energy Imbalance Service market saw “very limited growth” in its first 13 months, SPP’s MMU said in its first annual report on the market.

SPP regulators have approved a recommendation for three DC ties that will connect the RTO’s Eastern and Western Interconnection footprints.

SPP is continuing its delicate dance with Western utilities with a charm offensive that includes a first-hand look at the RTO’s sausage-making process.

CAISO issued a straw proposal for its extended day-ahead offering in the Western Energy Imbalance Market, a renewed effort at greater Western regionalization.

A group of Western utilities plans to help SPP develop its Markets+ program in the West and to examine the benefits of joining it or CAISO's day-ahead market.

SPP says its Markets+ day-ahead offering in the Western Interconnection is on track to be completed by the end of the year.

SPP said it plans to close its Western Energy Imbalance Service, with members joining either its proposed Markets+ program or its Western RTO.

CAISO, SPP and the Western Power Pool are all maneuvering to organize the Western electricity sector, and conditions finally seem ripe for change.
