Washington pilots integrated energy storage and consumer DERs


Washington-based utility Puget Sound Energy has partnered with Sunverge to implement its smart grid pilot project.

The utility will use Sunverge’s platform to integrate battery energy storage systems with consumer on-site distributed energy resources including solar photovoltaic, smart thermostats, electric vehicle chargers and other smart controllable loads.

The aim is to ensure grid reliability, as well as reduce consumer energy bills and carbon footprint by making the grid greener and smarter for the state’s largest utility.

The system will be used by both the utility and consumers to monitor onsite energy generation, storage and usage, as well as grid status and integrated energy.

Ben Farrow, manager of new products and services at PSE, said: “These batteries can help by giving our customers reliable backup power, while providing us with the ability to learn more about operational capabilities and efficiencies of energy storage on our distribution grid.

“By gaining experience with battery storage on our grid, we hope to expand this technology to benefit all customers in the future.”

Martin Milani, CEO of Sunverge, added: “DERs and Virtual Power Plant technologies are becoming a key component in many utilities’ future planning. Increasingly, it will be a required capability to achieving the optimal mix of traditional infrastructure, renewables integration, grid modernisation, resiliency and cost-effective demand-side management efforts and programmes.”

Puget Sound Energy serves 1.1 million electric and 825,000 gas customers in 10 counties.
