Following the sale of its U.S. operations to Hull Street Energy, FirstLight, will continue its Canadian operations under a new identity: Caelo Energy. This transition will have no impact on our development and operations activities in Canada, which will continue as planned.
About us
Our name, Caelo (KY-loh), is derived from the Latin word caelum, meaning "sky." It reflects the source of the natural elements that power our projects: the sun, the wind, and the water, and our commitment to developing renewable energy that benefits both people and the environment.
Formerly operating as FirstLight Canada, which brought together legacy platforms H2O Power and Hydromega, Caelo Energy represents the next chapter in our evolution. With a focus on the Canadian market, we are building a diverse portfolio of energy projects that support Canada's growing electricity needs while helping achieve long-term climate and energy goals.
Our vision
Building on decades of experience as a renewable energy operator and developer, our mission is to expand our assets across Canada through responsible development, meaningful partnerships, and operational excellence. As the energy landscape continues to evolve, Caelo Energy is uniquely positioned to help shape a cleaner, more resilient, and sustainable energy future.

About the Fort Frances Solar Project
Caelo is developing a solar project with a capacity 57.2 MWac on a combination of Municipal and private lands North of Fort Frances.
The project was submitted into the Ontario Independent Electricity System Operator (IESO) Long Term energy procurement process (LT2) that aims to bring new low carbon energy generation online to support Ontario’s forecasted economic and population growth.
The Fort Frances solar project would have the potential to supply clean electricity to approximately 8,000 Ontario households based on current average residential consumption.
Our Partnership
Indigenous Peoples have a vital presence and deep connection to the land where Caelo operates. In line with our commitment to respectful, long-term, and mutually beneficial relationships, we work with Indigenous communities to plan and deliver projects responsibly and inclusively.
This approach also supports the IESO’s objectives under the Long-Term 2 (LT2) procurement, which encourages Indigenous participation in energy projects to strengthen local partnerships and advance shared economic opportunities. As a 50% partner, Lac des Mille Lacs First Nation will be involved in the Project’s development. The Project will also support the First Nation’s growth, vision, and prosperity.
Project Updates
- Caelo Energy, in partnership with Lac des Mille Lacs First Nation, signed a Power Purchase Agreement (PPA) with the Independent Electricity System Operator (IESO) for the 57.2 MW Fort Frances Solar Project.
- Caelo has carried out preliminary engagement with the local community focusing with an initial presentation to the Fort Frances Mayor and Council in November 2024, providing an overview of the potential projects.
