Xcel's Public Service Company of Colorado decided to delay its entry into CAISO's Western Energy Imbalance Market in order to re-examine its decision.

SPP said it expects normal conditions and no extreme operation situations within its balancing authority and reliability coordinator footprints this summer.

SPP’s Western real-time energy market has attracted another participant in Colorado Springs Utilities, which is also interested in full RTO membership.

State regulatory staff working on SPP’s review of the RTO’s performance during the February winter storm said they are focusing on resource adequacy.

SPP said that a planned expansion into the West has attracted another potential member in WAPA's Colorado River Storage Project.

COVID-19 and record hurricane and wildfire seasons made 2020 “a unique and at times challenging year,” FERC said in its State of the Markets report.

Utilities are hoping their participation in SPP's WEIS market will be the "first step" to full RTO membership.

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.

SPP successfully launched its WEIS market, making it the first RTO with power markets in both the Western and Eastern Interconnections.

Stakeholders in SPP’s Western Imbalance Service market unanimously approved its Feb. 1 launch, the last major milestone in a project that began in 2019.
