Medway Grid Energy Storage System
Project Summary
The Medway Grid Energy Storage System will use a group of rechargeable batteries to store excess electrical energy at times of low demand, which can then be released later in response to increased demand. The Medway Grid Energy Storage System will enhance the flexibility and reliability of the grid without creating emissions or waste products.
System Details:
Generation: 250 MW/2 Hours
Parcel Area: 10.6 Acres
Location: Milford Street, Medway, MA
Safety: Site will be remotely monitored 24/7 with adherence to FERC and NERC standards
Located strategically near an existing utility substation and transmission right of way.
What is Battery Storage?
Battery energy storage systems (BESS) use a group of rechargeable batteries to store excess electrical energy, which can then be released later in response to increased demand. A few benefits of a BESS include:
Faster, more flexible, and lower-cost electricity: a BESS can respond in milliseconds, increasing both speed and reliability
Integration with renewable energy and electric vehicles
Cleaner storage: batteries do not create emissions or waste products, and do not require water for operation
Adheres to international, national, and state safety requirement standards and best practices
