Jupiter Power is investing in Everett to strengthen the Commonwealth’s energy grid.
Jupiter Power is redeveloping part of an old oil terminal in Everett with an energy storage project
The Trimount Energy Storage Facility (Trimount) will support a growing tax base for Everett
Trimount will improve electric reliability through a connection to Eversource’s Mystic Substation and support urban resiliency
Trimount will support the Commonwealth’s clean energy and decarbonization goals
Jupiter Power is putting proven project execution capability and significant capital to work to help make the energy transition a reality. Jupiter Power operates one of the largest fleets of energy storage in the country.

Project Location and Purpose
Trimount’s development will transform approximately 20 acres of the idle 100-year-old former oil terminal site, supporting the long-overdue environmental remediation of the area
Trimount will connect at that Mystic substation, repurposing existing grid infrastructure from the retiring plant to integrate clean energy and provide reliable power to the metropolitan region.

Why Battery Energy Storage?
- Emergency support: Batteries are an excellent way to store energy for use in times of need. Batteries help reduce the risk of supply or demand-related outages.
- Energy demand: Morning and evening hours are typically when the largest amount of energy is needed from the grid. During these times, we can pull energy from batteries to meet the high demand and reduce strain on the local energy infrastructure.
- Maintain stability and power quality: Supply and demand of energy fluctuate throughout the day and do not always line up. This can be a problem because homes and businesses need reliable energy, and the grid must maintain the proper voltage and frequency. Batteries help even out the fluctuation of energy on the grid, providing consistent and stable electricity, 24/7.

Community Benefits
Jupiter Power is working with the City of Everett and its residents to develop this project in a manner that is compatible with plans to revitalize this part of the city is a top priority of Jupiter Power. Everett has served as the host for unwanted negative fossil fuel impacts. Jupiter Power proposes to to replace this old infrastructure with cleaner, sustainable energy infrastructure, with benefits including:
- $500+ million total investment in the City of Everett
- Boosting annual tax revenues to the City of Everett and Everett public schools
- Creation of hundreds of jobs during the four-year site remediation, grading, and construction processes
- A highly compatible façade with commercial redevelopment in the Lower Broadway area and negligible traffic impacts in the neighborhood
- Reducing air pollution from fossil fuel electric generation to improve air quality and the advancement of public health in Everett and surrounding areas
- Support the Commonwealth’s climate goals of 50% CO2 reduction by 2030 and carbon neutrality by 2050
- Approved use for Chapter 91 Designated Port Area (DPA), providing energy storage integration that would support future offshore wind development
Project Schedule
The Trimount project is currently in the community outreach and permitting phase. Environmental clean-up of Trimount’s portion of the former fossil fuel site is underway and is currently on course to be completed in 2026.
Construction of the project, which is dependent on successful permitting and commercialization, would follow full completion of the site remediation. The project expects to begin commercial operations in the latter half of the decade.

The Trimount Legacy
The Trimount battery energy storage project is named in homage to the three hills that once defined the Boston skyline before they were largely removed to reclaim land for the Boston area.
