GRID-SCALE BATTERIES: ENABLING A CLEAN ENERGY TRANSITION
A mix of energy solutions is needed for Nova Scotia to meet provincial and federal environmental targets, which include getting off coal and reaching 80% renewables by 2030.
To help us reach these goals, we are proposing three new 50MW/4-hour grid-scale battery facilities located in Bridgewater, the Valley, and Halifax Regional Municipality.
Batteries and other energy storage technologies are essential in our move towards more renewable electricity. As our province introduces more wind capacity and investigates the future potential of hydrogen sources, additional energy storage is needed to ensure energy is there when Nova Scotians need it and to increase reliability for customers.
Our project team has been working with stakeholders and engaging communities as preliminary planning continues for the proposed facilities. On January 25, 2024, we filed the proposed project with the Nova Scotia Utility and Review Board, seeking approval for the capital costs required to develop the grid-scale battery facilities.
If approved, construction on the proposed sites will begin in 2024 and continue through 2026, with the first site operational by 2025.
How They Work
Our proposed grid-scale battery facilities will have various functions that will benefit the grid throughout the clean energy transition. These benefits include:
- Fast response to unplanned grid disturbances
- Safe, reliable, and clean energy during peak demand
- Opportunity to introduce and enable more renewable energy
These grid services are central to the safe and reliable operation of the transmission system and currently are largely provided by NS Power’s existing coal units. The ability of a utility-operated battery energy storage system to provide these services will contribute to the further integration of renewables onto the grid in a safe, cost-effective, and less carbon-intensive manner.
