In the coming months, we will be highlighting PSE’s innovative battery projects around our service area. Each project is forging a path to innovative, flexible, and exciting new solutions – and a better energy future for us all.

This month, we’re focusing on an initiative right here on Bainbridge: a Residential Battery Demonstration!

In November 2019, PSE began testing behind-the-meter (BTM)* 6kW/15.5kWh battery units on five Bainbridge Island homes. The goals for this project are evaluating back-up power during outages and peak shaving – which is a term for reducing power consumption on the electrical grid during periods of high demand.

These lithium-ion, consumer-scale batteries are Sunverge One systems that use a proprietary software platform for operation. Mounted on the side of the home, next to the meter, each battery weighs 725 pounds and is stored in a metal cabinet that measures 76 inches tall, 34 inches wide, and 14 inches deep.
