who is firstlight?

FirstLight Power is a leading clean power producer, developer and energy storage company serving North America. The company is also a steward of more than 14,000 acres and hundreds of miles of shoreline along some of our most beautiful rivers and lakes.

For decades, our renewable assets have been delivering clean, safe, reliable electricity to serve our communities. To meet the demand for clean energy as states and provinces transition away from fossil fuels, FirstLight has advanced our mission and swiftly expanded our portfolio to include solar, battery storage and investments in offshore wind – in addition to our legacy pumped-hydro and hydroelectric assets.

We also welcome visitors for boating, camping, hiking, cross-country skiing, birdwatching, picnicking and other recreational and nature-education opportunities at our facilities.

FirstLight's Vision and Our Values

our people

We are proud to employ more than 180 employees, many of which are proudly unionized. We have built a strong leadership group and we are actively seeking additions to our team who are passionate about the clean energy industry and shaping our future.

Our FirstLight family works together to advance our mission to accelerate the decarbonization of the electric grid by supporting the development, operation, and integration of our renewable energy and storage assets by delivering an electric system that is clean, reliable, affordable, and equitable.

Our Dedicated Team and People


FirstLight strives every day to maintain a strong commitment to social responsibility. Our lakes and generation facilities are already important economic drivers to our host communities, but we also believe in being a good neighbor.

We provide opportunities for local environmental, educational, and public safety organizations to compete for grants, support our local lake authorities, and collaboratively work with our neighbors to maintain and improve the local environment.

FirstLight's Contributions to Our Communities

what does firstlight do?

FirstLight is a renewable energy producer, renewable developer, and energy storage company specializing in hybrid solutions that pair hydroelectric, pumped hydro storage, solar, large-scale battery, and offshore wind assets to create reliable clean energy.

We operate dozens of facilities across North America and proudly serve our host communities and beyond through our clean energy assets, the recreation spaces we steward, and the jobs we produce. In addition to keeping the lights on, FirstLight’s assets are vital resources that help to maintain the reliability of the energy grid.

what is hydroelectric power?

locations of firstlight facilities

FirstLight operates 20+ hydroelectric generating facilities in Massachusetts, Connecticut, Pennsylvania, and Ontario, Canada, collectively producing hundreds of megawatts (MW) of clean power. In addition, we operate an 18,000-panel solar farm at Northfield Mountain, two of New England’s largest energy storage facilities, located in Western Massachusetts and Western Connecticut, and two battery storage facilities at UMass Dartmouth and Brandeis University.

We’re also actively developing over 2,000 MW of solar, battery and offshore wind projects to meet the growing clean energy needs in North America and beyond.

Our administrative offices are in Northfield, MA, New Milford, CT, and Oshawa, ON, and our corporate headquarters are located in Burlington, MA.

firstlight green initiatives

FirstLight is committed to environmental stewardship. Our assets are clean, renewable resources that have served as the backbone of New England’s carbon-free fleet since the Industrial Revolution. Each hydroelectric impoundment is managed in consultation with many stakeholder organizations, such as lake authorities, to ensure that lakes, shorelines, recreational facilities, open space, and the rivers themselves are protected from environmental harm. In recent years we have built fish passage facilities, developed and implemented shoreline management plans, and adopted operational best practices that prevent environmental accidents. We have also given back to the community through our grant programs, which to date have contributed more than $1 million in funding for many different projects designed to protect our environment and improve public safety in the communities.

spotlight on: northfield mountain generating station

FirstLight’s largest energy facility is Northfield Mountain in Massachusetts, a “pumped storage” facility commissioned in 1972 that can store more than 8,700 megawatt-hours of electricity every day, which is enough electricty to power more than 1 million homes. Northfield Mountain is known as New England’s “biggest clean battery” and also provides critical backup to our regional electric grid, able to ramp up to its full capability on less than 10 minutes’ notice, which is extremely fast for such a large generation facility.
