Puget Sound Energy (PSE) and Renewable Energy Systems Americas (RES Americas) signed agreements to cooperate on launching an innovative battery storage project in Whatcom County, Washington. Electricity will be stored in battery modules that are as large as 40-foot shipping containers and will be capable of providing up to 18 hours of power during an outage for the core area of Glacier. PSE is working with Washington State’s department of commerce in developing this pilot project. In July, the state's Department of Commerce Clean Energy Fund awarded PSE $3.8 million to engineer and construct a 2-MW, 4.4-MWh lithium-ion battery system at the existing PSE Glacier substation near State Route 542. Construction is expected to begin as early as June 2015.
