Battery Energy Storage System (BESS)

PSE currently does not plan to install a battery energy storage system (BESS) on Bainbridge Island.  

In 2019, PSE shared our proposed solution to meet Bainbridge Island’s identified electric reliability and capacity needs. At that time, we considered installing a BESS within the Murden Cove Substation. Since 2019, we have more information and details that have helped us refine our solutions to meet the energy needs of the community.  

Based on new information and our analysis, we no longer propose to install a BESS on Bainbridge Island. We are looking at other options at the Murden Cove Substation, including adding a second transformer in the existing substation, to meet our customers’ energy needs.
