Additional information

The Utility Regulation and Competition Office (‘OfReg’) has approved a request from Caribbean Utilities Company, Ltd. (CUC) for a 20 MW Utility-scale Battery for its Instantaneous Reserves project. CUC will store a relatively small amount of energy with the primary function of providing backup power for its North Sound Road power generation plant which in turn will reduce the generation plant’s fuel usage. The primary function of the battery is to provide ‘instantaneous or spinning reserve’ in the event of power generation plant failure. That is, if an operating generator fails, the battery will instantly provide the shortfall in energy until other generators can be brought online.
