The Wind Energy Institute of Canada used its 1 MW/ 2 MWh storage system to reduce the electricity consumption of their 10 MW Wind R&D Park during periods of low wind. The storage system was charged during periods of high wind and that energy was released to the turbines and network when the wind power dropped below 0 kW. Despite December being historically one of the windiest months at North Cape, in 2014 there were three extended periods without significant wind power. This resulted in the battery reaching bottom state of charge and not being able to reduce the demand charge. The storage system was able to offset 8705 kWh, but this was insufficient to offset the net losses in the storage system for December 2014.
