Grand Cayman, Cayman Islands – On August 1, 2025, Caribbean Utilities
Company, Ltd. (“CUC”) announced an agreed approach with the Utility Regulation
and Competition Office (“URCO”) to address the pressing demand for increased
generating capacity in Grand Cayman. As part of this strategic alignment, CUC
committed to withdraw its initial Certificate of Need (“CON”) submitted on June
7, 2024. In conjunction with this withdrawal, URCO formally rescinded its Final
Determination on CUC’s Certificate of Need issued on April 24, 2025. A key
feature of this agreement was that solar generation coupled with battery storage
may be able to provide firm capacity subject to industry standard analysis.

In alignment with the recently established agreement, CUC is pleased to confirm
the submission of a new CON to the regulator for formal review.
This updated filing outlines the generation resource requirements essential to
meet Grand Cayman’s projected energy demand with a need for additional
generation capacity to be in place by 2027.

CUC’s submission includes a comprehensive system analysis, detailed load
forecasts, and operational benchmarking designed to ensure sufficient capacity
and energy availability by June 2027. The timeframe for supply of the needed
capacity is very short, and it is likely that interim measures may need to be taken
to fulfil the needs of the grid in the short term.

The new submission differs from the prior document in that the generation
capacity and reliability requirements are outlined but no specific technology is
recommended. Instead, it is anticipated that URCO will issue a Request for
Proposal (“RFP”) and bidders will be allowed to propose alternate resource
solutions to meet that need.

CUC conducted additional analyses to provide URCO with an example
methodology to evaluate the potential contribution of alternate generation
solutions, such as the Dispatchable Solar Photovoltaic (“DPV”) project, which was
recently issued as a request for proposal, to support forecasted load
requirements.

President and CEO, Mr. Richard Hew states:
“CUC remains steadfast in its commitment to accelerating Grand Cayman’s
renewable energy transition, ensuring that it is secure, affordable, and delivers
lasting benefits to households, businesses, and communities we serve.”

Through continued collaboration, innovation, and investment in sustainable
technologies, CUC is dedicated to building a resilient energy future that
promotes economic prosperity, environmental stewardship, and ensures
affordable, equitable access to energy for all. As we move forward, CUC remains
focused on delivering solutions that meet today’s challenges while laying the
foundation for a cleaner, more sustainable tomorrow.
