The Regional Grid Interconnection Study
Perhaps the most technically ambitious outcome of the summit was the announcement of a formal feasibility study for Eastern Caribbean grid interconnection. The concept — linking the electricity grids of neighboring islands via undersea high-voltage direct current (HVDC) cables — has been discussed for decades but never seriously funded. The new study, to be conducted by a consortium including IRENA and the OECS Secretariat, will assess the technical and economic viability of connecting Antigua, Montserrat, Guadeloupe, and Dominica in an initial phase.
The economic logic of interconnection is compelling: Dominica has significant untapped geothermal energy potential, Antigua has excellent solar resources, and Guadeloupe (as a French overseas department) has access to EU renewable energy financing mechanisms. A connected grid would allow each island to specialize in its lowest-cost generation technology while sharing backup capacity, reducing the need for expensive diesel peaker plants on each island. The study is expected to take 18 months and cost approximately EC$3.5M, with results available in mid-2027. Actual construction, if approved, would be a decade-long project — but the feasibility study is the essential first step.
The IADB Financing Package
The Inter-American Development Bank announced a EC$50M financing package for Eastern Caribbean renewable energy projects, available as a combination of concessional loans (at approximately 3.5% interest over 20 years) and technical assistance grants. Eligible uses include utility-scale solar projects, grid modernization, battery storage systems, and regulatory capacity building for energy ministries and utilities. For Antigua, the most immediately relevant application is the utility-scale solar procurement process currently underway, which requires significant upfront development financing that commercial lenders have been reluctant to provide without IDB co-financing.
The technical assistance grant component is equally important, though less discussed. Antigua's energy regulatory capacity gap — the absence of an independent regulator with technical staff capable of reviewing interconnection applications, setting tariff methodologies, and enforcing grid codes — is one of the primary bottlenecks limiting solar adoption. IADB grant funding for regulatory capacity building could directly accelerate the permitting backlog resolution and the net metering regulation process. The Antigua delegation reportedly prioritized this in bilateral discussions with IADB representatives on the sidelines of the summit.
CARICOM Target Reaffirmed Despite Setbacks
The summit reaffirmed the CARICOM target of 45% regional renewable energy by 2030, despite evidence that the region as a whole is significantly behind trajectory. IRENA data presented at the summit showed the region at approximately 18% renewable penetration on a capacity-weighted basis — short of where it needs to be to reach 45% in four years. Barbados and Dominica are ahead of target; most other nations, including Antigua, are behind. Ministers acknowledged the gap but framed the target as directionally correct even if the specific year proves aspirational.
For Antigua, the political optics of attending a regional summit while one of the furthest behind on the shared target is uncomfortable, and the government delegation was reported to have committed to accelerating the national utility-scale procurement as a condition of maintaining credibility in regional discussions. Whether that political commitment translates into administrative action — specifically, finalizing the procurement terms for the IDB-backed solar project by Q2 2026 — will be the key test of the summit's practical impact for Antigua.
