It will supply the 10 MW system to Bermuda Electric Light Company (BELCO) to provide up to 10 MW power for spinning reserves and frequency response to maintain grid stability.
Like many islands, Bermuda has relied on imported fuel to generate much of its electricity. However, the island is modernizing its approach to generation and distribution following the passing by the government of the Electricity Act in 2016.
This prompted BELCO to develop a long-term plan which includes measures to improve energy efficiency, storage and renewable energy.
Spinning reserves are essential to provide backup power in case a generator experiences a sudden outage. The Saft storage system will provide spinning reserves, allowing the operator to switch off generators and save fuel.
The system will also provide frequency response services, by injecting or absorbing energy to or from the grid within seconds to maintain consistent frequency and grid stability.
Saft will build the containerized Li-ion battery systems ESS in Jacksonville, Florida. The storage system will integrate control and monitoring equipment, as well as power conversion components and switchgear supplied, by ABB.
