Oregon Utility Commences Flow Battery Field Tests

The long-duration iron electrolyte flow battery energy storage solution developed by ESS Inc. will be utilized in a test and demonstration project conducted by Portland General Electric. ESS Inc. is the sole manufacturer of the 3MWh flow battery, which doesn’t possess toxic electrolyte chemistry. The company holds a number of patents of its flow battery, which can be integrated into energy storage systems that provide up of 12 hours of discharge duration and storage.

Portland General Electric, the utility firm that will deploy the battery, plans to test the battery system’s ability to offer various applications with different use cases, including demand response, voltage and VAR support, contingency reserve, frequency response and resource optimization.  ESS Inc.’s system will be situated on an area that is adjacent to its factory headquarters in Wilsonville, which is a small city in the state of Oregon.

The system is expected to come online by mid-2022, with the senior manager of grid edge solutions at Portland General noting that working with ESS on the project would afford the company necessary lessons on the path to meeting reduction targets for greenhouse gas emissions. Darren Murtagh of Portland General Electric added that building an affordable and reliable, clean energy future required industry innovators to work together with utility companies.

This project marks the maiden deployment of a containerized, configurable utility-scale product dubbed the Energy Center Product, which was designed by ESS. The product was developed for industrial and commercial applications as well as front-of-meter use cases. The product was launched in February 2021 and is based on the firm’s second generation of flow battery modules.

Soon after the launch, an announcement was made stating that six Energy Warehouse units would be utilized in a zero-emissions, micro-grid project in California. San Diego Gas and Electric, an investor-owned utility based in California, plans to deploy solar in combination with the flow battery equipment to support various community facilities in Cameron Corners.

The state of California has been adopting the use of long-duration energy storage technologies, as it did with lithium-ion battery and solar PV storage. California’s budget for 2022–2023 has $380 million in funding for long-duration energy storage projects.

ESS Inc. is focused on ramping up its manufacturing and building up contracts and deployments, with a statement it released in November 2021 indicating that the company believes that its pipeline of opportunities will be worth $8 billion in the international markets by 2027.

The field of flow battery systems is seeing a lot of innovation, and many alternative chemistries, including the vanadium flow battery chemistry focused on by entities such as StorEn Technologies Inc., are gaining traction on the market.
