Grand Cayman seeks renewables proposals, including hydro, ocean energy

Caribbean Utilities Co. Ltd. (CUC) invites expressions of interest and preliminary proposals for financing, construction, ownership, and operation of renewable energy generating facilities, including hydropower and ocean energy, on Grand Cayman Island. Responses are due October 31.

CUC relies upon diesel generation, and two gas units, totaling 151.22 MW to serve its 26,000 customers on Grand Cayman, the largest of the three islands in the Cayman Islands, a Caribbean colony of Great Britain. The utility said current high oil prices and advancement in renewable energy technologies prompted it to seek vendors who could provide feasible utility-scale renewable energy projects.

The company seeks proposals for projects of a minimum of 50 kW to a total installed capacity of 13 MW of grid-connected generation on Grand Cayman. Proposals for projects larger than 5 MW are to include option pricing for systems that are less than or equal to 5 MW.

CUC said it envisions that successful investors would become independent power producers that would enter power purchase agreements with CUC. The Cayman Islands Electricity Regulatory Authority approved a feed-in tariff structure in February that is intended to provide significant incentives to those who generate electricity from renewable resources.

Although the solicitation does not specify types of renewable energy, CUC Energy Services Manager Sacha Tibbetts told that hydropower and ocean energy proposals are welcome options.

“The interested party would need to do their own feasibility analysis and determine whether they could produce a project that would offer cost-effective power generation,” Tibbetts said.

The request for expressions of interest may be obtained from the CUC Internet site at

Responses are due October 31. Successful developers are to be notified December 31 and invited to negotiate power purchase agreements.
