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


NORMAN, Okla.–(BUSINESS WIRE)–A large federal energy marketing entity (client) has successfully joined the Western Energy Imbalance Market (WEIM) operated by the California Independent System Operator (CAISO), with a go-live date of May 3, leveraging PCI’s state-of-the-art cloud technology platform.

PCI’s President and COO, Javier Martin, said PCI’s software and cloud infrastructure, along with a hard-working and determined team, made it easy to complete this complex project in which the client integrated its Federal Columbia River power system to PCI’s WEIM solutions for its merchant and transmission workflows. .

“This go-live marks the beginning of our long-term relationship with our customer in a new business context of being part of an imbalanced wholesale market,” Martin said. “Participation in EIM West will help our customer optimize hydroelectric capacity and load service, providing operational and economic benefits for excess electricity and savings on short-term purchases.”

In addition to this customer, six other neighboring balancing authorities have updated their PCI transmission system configurations to take into account the planning of exchanges with the new WEIM participants. These 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).
