- The Greenwater Battery Energy Storage System (BESS), with a 200 MW/800 MWh capacity, enhances Puget Sound Energy’s (PSE) energy management and addresses rising electricity demand in Washington.
- By storing excess energy from renewable sources, Greenwater allows PSE to redistribute power during peak consumption, reducing reliance on non-renewable sources.
- The project generates an estimated $43 million for local infrastructure and funds STEM programs in schools, supporting regional energy independence and workforce development.
The Greenwater Battery Energy Storage System (BESS) enhances Puget Sound Energy’s (PSE) energy management. With a 200 MW/800 MWh capacity, it meets rising electricity demand in Washington.
As demand increases, the Greenwater project provides a vital energy reserve for peak times and fluctuating renewable energy production. It reflects a growing trend of energy storage systems balancing power grids.
Greenwater is located in Pierce County near consumption centres, reducing the need for costly new transmission lines. This strategic positioning allows quicker deployment of energy resources and makes the system more responsive.
By storing excess energy from renewable sources like solar and wind, the Greenwater BESS helps PSE redistribute energy during peak consumption. This strategy decreases reliance on non-renewable sources and enhances energy security.
The project aligns with the Western Resource Adequacy Program (WRAP) objectives and ensures a reliable, affordable energy supply in the Northwest. It also complies with the Clean Energy Transformation Act (CETA), which mandates increased renewable energy in PSE’s mix.
The Greenwater project bolsters PSE’s ability to provide continuous service, even during extreme weather. It promises significant economic benefits, generating an estimated $43 million for local infrastructure, including schools and emergency services.
Additionally, it funds STEM programs in local schools, preparing future talent for renewable energy careers. This initiative forms part of a larger strategy to enhance regional energy independence and develop sustainable business models.
As Greenwater sets a benchmark for energy storage, it could encourage more regional projects. This development will support the energy transition and help meet decarbonisation goals, underscoring the need for innovative energy management strategies.
