Caribbean Utilities Company, Ltd. (CUC) is the sole provider of electricity to Grand Cayman.
To obtain electricity services, property owners are required to complete and sign an application for electrical service, pay a deposit for post-pay service (there is no deposit required for pre-pay electricity), show proof of ownership and a photo ID. Tenants are required to complete and sign an application for electrical service, pay a deposit (for post-paid accounts), provide a signed rental agreement or lease and submit a photo ID. Applications should be submitted online. Customer application forms can be found on CUC’s website. CUC’s customer service centre is located at Caribbean Plaza on West Bay Road and customer service representatives are available to answer inquiries in person Monday to Friday 9am-4pm (not including public holidays). All other business should be conducted by telephone or email. All customer-related services and offerings can be completed digitally or remotely.
The security deposit required for existing post-paid electricity accounts (billed monthly) is calculated based on the average historical usage of the property for 45 days of consumption. Deposits for newly constructed residential homes/condos are calculated based on square footage and the number of bedrooms.

Grand Cayman runs on a 120 volt electricity system with three-pin plugs. However, outlets can accommodate a two-pin American plug (see image).
Electricity Rates
Monthly electricity bills will vary depending on the size of your house condo/apartment, your lifestyle, how often (and cold) you run your air conditioning, the efficiency of your air conditioning unit, the age of the property and how well the property is insulated, among other factors. It is important to note that the Seasonal Energy Efficiency Rating (SEER) and regular maintenance of your air conditioning unit can make a big difference in kilowatt-hour (kWh) consumption and your monthly electric bill. The lower the SEER, the more energy will be consumed for the same amount of cooling. A SEER of 16 for example, will consume more electricity than a SEER of 18 or higher. Managing your energy usage and getting your air conditioning units serviced regularly will ultimately save you money.
The cost of electricity is the same Island-wide and does not fluctuate depending on the time of day. Bill payments are not accepted at the customer service centre, but details on the numerous payment methods are listed under ‘Payment Methods’ on the Company’s website.
