Portland General Electric taps ESS to provide 3MWh Energy Storage for test project

Pacific Northwest municipal utility Portland General Electric will agreed on testing and demonstration of a 3-MWh battery storage alternative to lithium-ion systems.

Long-duration energy storage, iron-flow battery manufacturer ESS Inc. will provide its Energy Center platform for the testing and demonstration of the technology. The 3-MWh ESS platform would come online midway through this year and be used to demonstrate several benefits such as frequency response, contingency reserve, voltage and VAR (volt-ampere reactive) support, demand response and resource optimization, according to the release.

The project will be on land adjacent to ESS’s factory headquarters in Wilsonville, Oregon.

Portland General Electric, which serves about 900,000 customers in the region, is moving actively to embrace energy storage and renewables to decarbonize its generation mix.

“Building a reliable, affordable clean energy future requires us working together with industry innovators,” said Darren Murtaugh, Senior Manager of Grid Edge Solutions at PGE. “Our collaboration with ESS on the Energy Center will provide important learnings on our path to meeting our greenhouse gas emission reduction targets.”

The Energy Center is the ESS “battery-in-a-building” platform designed for utility-scale, front-of-meter applications that decouples power and storage capacity to eventually enable up to GW-scale projects with variable storage durations ranging up to 12 hours.

“As an American manufacturer of safe, sustainable long-duration energy storage technology for a growing global market, I couldn’t be happier that the first Energy Center deployment will be right here in our backyard with Portland General Electric,” said Eric Dresselhuys, CEO of ESS. “The Energy Center platform has been developed as a flexible long-duration storage solution with a planned 25-year operating life, and this project will help PGE work towards its renewable energy targets.”

Barely a decade old as a company, ESS already is moving into several supply deals with major utilities in the battery storage and microgrid spaces. Last month, ESS Tech announced that utility San Diego Gas & Electric has selected its iron flow batteries to join with the solar arrays in the microgrid being built in the Cameron Corners community.

The Cameron Corners Microgrid is part of SDG&E’s 2020 Wildfire Mitigation Program.

EnergyTech spoke to leaders at ESS this week during the Intersolar-Energy Storage North America conference in Long Beach, California. A story on that interview will be forthcoming.
