news item image
Wärtsilä will supply two 10-megawatt (MW) energy storage systems under an engineering, procurement, and construction (EPC) contract to Caribbean Utilities Company Ltd (CUC) in the Cayman Islands.
This project, which will be CUC’s first energy storage facilities, will enable the utility to approximately double its renewable energy capacity on Grand Cayman, the largest of the three Cayman Islands.
The new energy storage facilities will allow CUC to operate its generating assets in a more efficient manner reducing fuel costs to electricity consumers.
Additionally, the energy storage systems will facilitate up to a total of approximately 29 MW of distributed customer-sited renewable energy resources without causing instability to the grid.
Each facility will include Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s sophisticated energy management system.
“We are pleased to work with Wärtsilä to establish our first energy storage systems. This represents a crucial step for CUC to integrate more renewable energy into the grid. Once this project is completed, we anticipate savings on fuel costs and improved reliability of services for our customers on Grand Cayman,” said Sacha Tibbetts, vice president, customer services and technology, Caribbean Utilities Company.
