Portland General Electric formally agrees to join Energy Imbalance Market

Portland General Electric Company (PGE) and the California Independent System Operator (ISO) announced today they have filed an implementation agreement with the Federal Energy Regulatory Commission, paving the way for the Portland, Ore.-based utility to participate in the western Energy Imbalance Market (EIM) starting in October 2017.

PGE recently filed an assessment by Energy and Environmental Economics, Inc. with the Oregon Public Utility Commission, showing potential cost savings and efficiency gains for PGE and its customers from EIM participation and pooling of flexible reserves among EIM participants.

The western EIM is a real-time energy wholesale market that automatically dispatches the lowest-cost electricity resources available to meet utility customer needs while optimizing use of renewable energy over a large geographic area.

PGE is the most recent utility to announce participation in the western EIM. Phoenix-based Arizona Public Service and Puget Sound Energy are set to enter the market in 2016. Nevada-based NV Energy will begin participating on December 1, 2015.
