FAQs

Where will the project be located?

The Streamfield Energy Storage Facility will be located across two parcels on Medeiros Way, west of Route 202 in Westfield. The generation tie-line will run across Medeiros Way, near existing transmission lines, to interconnect at the Buck Pond substation, immediately adjacent to the southern parcel.

What will be located at the facility?

The Project will include the following equipment and associated facilities:

Lithium-ion batteries
Battery energy storage system containers
Thermal management systems for temperature control
Fire detection and suppression systems
Electric control equipment
Power Conversion Systems (Inverters / transformers)
Step-up transformer and project substation, including lightning protection, a control enclosure, and internal fencing
Communications equipment
A perimeter fence and security gate
115kV generator tie-line and utility interconnection
Other facilities required for construction and operation of the Energy Storage Facility

What will the facility look like?

The Project facilities will sit on approximately 13 acres across the two project parcels. It will be set back from the road and surrounded by as much natural vegetation as possible. The Project will be enclosed by a fence and project components will be shielded from view as best as possible from the road. The Project will not be visible from any nearby residences.

Is battery storage safe?

Yes! Safety is our top priority during construction, operations, and for the life of the battery. Project operations will not produce fumes, pollution, odor, dust, or other offsite impacts that would result in health impacts to those nearby and will not lead to increased traffic on local roads.

Jupiter Power uses only standardized, laboratory-tested and approved equipment, complies with all national Fire Codes and standards governing energy storage, and specifically engineers our projects so that in the extremely unlikely case of an equipment malfunction, any resulting event can be managed safely. In addition, each battery module within the containers is individually controlled and monitored, providing constant, 24/7 oversight capability over every component of the Project. The operational management systems will be designed, installed, and operated according to the national Fire Code standards and regulations which govern energy storage. Each container is equipped with an integrated system of sensors, alarms, and fire response systems and all relevant first and secondary responders in the community will receive annual training on the specifics of the facility.

Safe operations are enhanced by design parameters; state-of-the-art technology for monitoring, alarm, and fire response systems; and clear, open, and regular communication with first responders. Jupiter Power will work in close communication and coordination with the Westfield Fire Department and the Public Safety Communication Center throughout the process of project design and looks forward to continuing that cooperation throughout final design and for the life of the project.

How will this project benefit the community?

The Project will benefit residents and businesses by improving the power grid and supporting the local economy.

Battery energy storage is a proven technology that provides increased power to the grid and other grid management capabilities, like grid balancing through instantaneous battery energy storage response. With these capabilities, the Project will deliver more reliable power for residents and businesses—all without building new transmission infrastructure, funded by ratepayers.

The Project would represent a significant financial investment in Westfield. The Project will generate local tax revenue for the municipality for the life of the project. It will also create construction jobs and local sales tax benefits during construction.

When will construction start?

We're projecting to start construction in 2026 and be in service by mid-2027.
