Caribbean Utilities Company, Ltd. (“CUC” or the “Company”) today confirmed changes to electricity bills, effective June 1, 2026, following a review by the Utility Regulation and Competition Office (“URCO” or the “Regulator”). The Company remains committed to providing the public with notice of upcoming rate changes as early as possible. Where advance notice of at least one week prior to implementation is not feasible, the Company will aim to provide notice within one week of receiving formal confirmation from the Regulator. The changes reflect an approved adjustment to the Energy Charge, Facilities Charge, and the License and Regulatory Fees.
The rate adjustments support the Company’s continued investment in essential infrastructure, with a focus on improving reliability and fuel efficiency. The license and regulatory fee line item provides funding for the Regulator’s operations, ensuring effective oversight. The average residential customer consumed 1,158 kilowatt hours (“kWh”) per month in 2025. When compared to May, the impact of the rate changes in June (billed in July), utilizing the average monthly residential consumption (1,158 kWh), will be: • CUC-related rates (Energy Charge and Facilities Charge) - an increase of $3.27 • License and Regulatory Fees - an increase of $1.06 Lowering Costs Through Efficiency and Innovation CUC continues to prioritise investments that reduce fuel consumption and improve efficiency.
In 2025, these investments delivered US$7.9 million in fuel cost savings for Grand Cayman households and businesses, through initiatives such as battery energy storage systems, upgrades to generating units and resiliency projects. Q1 2026 showed continued progress, with approximately US$1.85 million in fuel cost savings. Projects that reduce reliance on diesel, including energy storage and increased integration of renewable energy, play a critical role in managing long-term costs. CUC continues to advocate for utility-scale solar development to support a more sustainable and cost-effective energy mix for Grand Cayman.
Utility-scale solar will not only reduce fuel costs associated with purchasing fuel; it will also deliver electricity at much reduced cost, with these savings available directly to consumers. Fuel Costs and Relief Measures CUC recognises the concern that consumers have about the impact on fuel costs due to the recent conflict in the Middle East. The Company will keep customers regularly informed about changes in fuel costs, which remain the largest component of electricity bills. These costs are entirely driven by global market conditions and are passed directly through to customers without any markup; CUC does not earn a profit on this line item of the bill.
For June consumption, a customer using 1,158 kWh can expect: • an increase of $63.46 on their bill due to fuel costs. For this consumption level, the Government’s Fuel Cost Relief Programme will provide: • a credit of $17.43. The average customer will see a net increase of $46.03 attributable to fuel. CUC supports the Government’s fuel relief programme which will continue to allow for credits on customers’ bills through the summer months and cap the fuel cost rate at CI$0.18 cents, within specified parameters, on electricity consumption for the months of June to September.

Customer Impact and Commitment “We understand that any change to electricity bills can be challenging, particularly during the summer months. We are committed to working with the Government through its Fuel Relief Programme. Despite these efforts, rising global fuel costs will see household energy bills increase. That is why we welcome the focus on enduring solutions including the return of the Cayman Home Energy Efficiency Retrofit ("CHEER") programme and acceleration of utility-scale renewable energy projects. The rate change for regulatory fees and CUC energy charges are carefully considered and necessary to ensure we can continue investing in infrastructure that improves efficiency, enhances reliability, and supports long-term cost stability for our customers,” said Mr. Richard Hew, President and CEO of CUC.
