Wartsila to supply 20 MW of energy storage to Grand Cayman utility

Finnish technology group Wartsila Corp (HEL:WRT1V) said on Monday that it has booked an order to supply two 10-MW/10-MWh energy storage systems to a utility company in the Cayman Islands.

It said it had secured the engineering, procurement and construction (EPC) contract from Caribbean Utilities Company Ltd (TSE:CUP.U), also known as CUC, to install its storage solution on Grand Cayman. The two sites will be equipped with Wartsila’s fully integrated, modular and compact energy storage system GridSolv Quantum, and the energy management system GEMS Digital Energy Platform.

According to Wartsila, Grand Cayman’s only sources of grid-connected power are CUC’s 161 MW of diesel-fuelled generation and about 14 MW of solar PV. The energy storage systems will enable CUC to operate its assets more efficiently and reduce fuel costs, and also pull in around 29 MW of distributed customer-sited renewable energy resources without destabilising the grid, Wartsila said.

The storage facilities, which will be the utility’s first, are expected to come online in mid-2023.
