Large U.S. Federal Power Marketing Entity Joins the Western Energy Imbalance Market

May 24, 2022 – Norman, OK – A large federal power marketing entity (Client) successfully joined the Western Energy Imbalance Market (WEIM) operated by the California Independent System Operator (CAISO), with a go-live date of May 3, by leveraging PCI’s state-of-the-art cloud technology platform. 

PCI President and COO Javier Martin said PCI’s software and cloud infrastructure, along with a hard-working and determined team, facilitated delivery of this complex project in which the Client integrated its Federal Columbia River Power System with PCI’s WEIM solutions for its merchant and transmission workflows. 

“This go-live marks the beginning of our long-term relationship with our Client in a new business context of being part of a wholesale imbalance market,” Martin said. “Participating in the Western EIM will help our Client optimize hydropower capacity and load service, providing operational and economic benefits for surplus power and savings on short-term purchases.” 

In addition to this Client, six other neighboring balancing authorities updated their PCI transmission system configurations to accommodate interchange scheduling with the new WEIM participants. They are Tacoma Power (TPU), Puget Sound Energy (PSE), Avista (AVA), Arizona Public Service (APS), Salt River Project (SRP), and Public Service of New Mexico (PNM).
