Extreme Temperature Battery Energy Storage System for Clean Energy at the Arctic Circle

Extreme Temperature Battery Energy Storage System for Clean Energy at the Arctic Circle

Saft has been selected by Northwest Territories Power Corporation (NTPC) to develop and install an extreme temperature Battery Energy Storage System (BESS) for use as part of a hybrid micro-grid that will deliver cleaner, more reliable and less expensive power to a community located 50 miles north of the Arctic Circle in Canada.

The system will be installed at the Colville Lake Power Station in June 2015 and will provide Colville Lake residents with consistent, renewable solar power and reduced diesel fuel consumption. Colville Lake is a remote, small community of about 150 inhabitants with temperatures that can drop to -50C in winter and reach 35C in summer. Currently, the community experiences a high incidence of power outages. The community can only be reached by road during a six-week period in February through March, when northern ice-roads are in use. Otherwise, it is accessed by flights. As such, the system was completed within a strict timeframe and delivered to Edmonton, where it is awaiting the final trek across the ice-roads when they are reopened.

Safts innovative Cold Temperature Package design allows for a complete BESS system in an ISO 20-foot container that withstands extreme arctic environments down to -50C. As part of the contract, Saft will develop and install one Intensium Max 20M Medium Power (IM 20M) Li-ion battery container with 232kWh of energy and a 200kW Power Conditioning System from ABB. The turnkey BESS will serve as the heart of the hybrid micro-grid that is part of a larger Solar and Diesel upgrade to the existing power plant.

This is NTPCs first project of this nature, and the first solar installation that has the capacity to generate about 30 percent of the communitys demand, said Emanuel DaRosa, President and CEO of NTPC.

In addition to design and installation, Safts advanced modelling capabilities helped NTPC determine the optimum size for their expanded solar array. To accommodate NTPCs long-term plans, Safts system is also designed with a modular set-up that can be expanded to integrate wind-energy and double the batterys energy rating in the future.

Hybrid micro-grids for remote locations are part of an emerging market for energy storage in which utility providers of isolated communities can regulate power fluctuations and high costs due to fuel transportation, said Jim McDowall, Business Development Manager at Safts Energy Storage Systems Business Unit in Jacksonville, Fla.
