Trenton Battery Energy Storage
RELATIONSHIP
SECTOR
The Trenton Battery Energy Storage Project is a proposed 150 MW battery energy storage system in the Town of Trenton, Nova Scotia, located in Piktuk, Mi’kma’ki, near Pictou Landing First Nation. The project is being developed by NRStor Trenton Energy Storage GP Inc., a jointly owned project organization involving NRStor, Wskijinu’k Mtmo’taqnuow Agency Ltd. (WMA), and Aecon Concessions. Once developed, the facility will draw and store electricity during off-peak periods, including periods of renewable energy generation, and release that power back to the Nova Scotia grid when electricity demand is higher.
The project is designed to support Nova Scotia’s clean energy transition by adding flexible storage capacity to the provincial grid. NRStor describes the project as a 150 MW, 600 to 1,200 MWh battery energy storage system, using lithium-ion technology. It is strategically located near one of the first coal facilities slated for shutdown, positioning the project to support the province’s move away from coal-fired electricity while improving grid reliability and enabling greater integration of renewable power.
For WMA, the Trenton Battery Energy Storage Project represents another step in building Indigenous equity participation in major clean energy infrastructure. Through WMA’s role, the project creates a pathway for long-term benefits to flow back to the 13 Mi’kmaw communities of Nova Scotia, while also supporting economic activity in the Trenton Industrial Park and surrounding region. NRStor estimates the project could generate significant economic value for the Nova Scotia grid, create direct employment opportunities, and contribute to the revitalization of a community affected by coal shutdowns.

The Trenton Battery Project is a proposed 150 MW battery energy storage facility in the Town of Trenton, Nova Scotia. The project is being developed by NRStor Trenton Energy Storage GP Inc., a jointly owned project organization involving NRStor, WMA, and Aecon Concessions.
The project is designed to store renewable energy during off-peak periods and release it to the grid during peak demand. The Spring 2025 newsletter noted that the project is expected to reduce greenhouse gas emissions by an estimated 1.8 million tonnes over its first 10 years of a 20-year project life, equivalent to removing 40,000 cars from the road annually.
Since the February 2025 open house, NRStor received positive reception from community members and secured a Municipal Support Resolution from the Town of Trenton.
The Confederacy of Mainland Mi’kmaq was contracted to conduct a Mi’kmaq Ecological Knowledge Study for the project. Other site studies, including environmental, geotechnical, and archaeological assessments, were also well underway at the project site.
