BC Hydro has selected S&C Electric Company, a renewable energy integration company, for a sodium-sulfur (NaS) battery energy storage project intended to improve service reliability for a remote mountain community in British Columbia. The energy storage system, which is funded, in part, by Natural Resources Canada’s Clean Energy Fund, will also reduce peak load demand for a second community, limiting carbon emissions and enabling deferral of capital expenditures.
The energy storage solution utilizes two battery systems, one installed in the community of Field and a second in Golden, BC, to provide back-up power for Field and to shave peak loads. The peak shaving application—which uses a novel approach where load is directly monitored and stored energy injected as needed—will allow BC Hydro to save on investments in transmission system capacity that would otherwise be required to meet peak demand.
For this project, S&C will engineer and install a complete energy storage solution featuring S&C’s Smart Grid SMS Storage Management System and IntelliTEAM SG Automatic Restoration System. This turnkey system will integrate the sodium-sulfur batteries on to the grid seamlessly, allowing the batteries to support a portion of the peak load depending on demand. This integrated solution optimizes total system efficiency and reliability for the community.
