Anguilla is one of the wealthiest territories per capita in the Caribbean, home to ultra-luxury resorts and high-end residential properties. It is also one of the most diesel-dependent, with the Anguilla Electricity Company (ANGLEC) running a grid that is approximately 99% diesel-fueled. Electricity rates of EC$0.44–0.55/kWh — among the highest in the XCD zone — combined with Anguilla's excellent solar resource (5.0+ peak sun hours per day) create solar economics that are compelling even at the higher equipment costs associated with shipping to a small island.
The ANGLEC Rate Environment
ANGLEC's rates have historically been among the highest in the Eastern Caribbean, driven by Anguilla's total diesel dependence, the small scale of the grid (peak demand approximately 18MW), and the shipping costs associated with fuel delivery to a small island with no harbor infrastructure for large tankers. The fuel surcharge component of Anguilla's electricity rate is particularly volatile, creating significant month-to-month variability for businesses and households trying to plan their energy costs.
XCD Economics for Anguilla Properties
At EC$0.50/kWh (a conservative midpoint of ANGLEC's rate range), a 5kW residential system generating 18,000 kWh per year (reflecting Anguilla's excellent sun resource) saves approximately EC$9,000 annually. Against an installed cost of approximately XCD 46,000–54,000, payback is 5.1–6.0 years. For luxury residential properties consuming 2,000–5,000 kWh per month, larger systems of 15–30kW are appropriate — and the economics scale favorably, with annual savings of EC$27,000–67,500 against proportionally larger installations.
Resort and Villa Economics
Anguilla's luxury resort sector pays commercial electricity rates in the EC$0.52–0.58/kWh range. For a major resort consuming 150,000 kWh per month, a 500kW solar installation (approximate cost XCD 1.6 million) generates approximately 90,000 kWh per month of offset electricity — annual savings of approximately EC$648,000 at EC$0.60/kWh blended commercial rate. Payback: approximately 2.5 years. The economics of commercial solar at Anguilla's electricity rates are extraordinary, and the reputational value of renewable energy credentials in the ultra-luxury market adds a further incentive.
Regulatory Context
ANGLEC's net metering framework is less developed than some regional peers, but the economic case for solar in Anguilla is so strong that even without favorable export rates, self-consumption-only systems achieve excellent paybacks. The British Overseas Territory regulatory structure means energy policy is shaped both locally and with UK government input. The UK's own net-zero commitments create some pressure toward favorable renewable energy policy for its overseas territories, which may support further regulatory development in Anguilla over the medium term.
