How Barbados Got to 30%
Barbados's renewable energy journey began in earnest with the Barbados Sustainable Energy Framework of 2019, which set a clear 100% renewable target by 2030 with binding milestones and identified the specific policy instruments needed to get there. By 2026, approximately 65MW of solar PV had been installed across three tiers: utility-scale ground-mounted systems totaling approximately 30MW; commercial and institutional rooftop systems totaling approximately 20MW (including the Sandals Resort installation mentioned in Issue #4); and residential net billing systems totaling approximately 15MW across several thousand homes.
The utility-scale component was critical. Barbados completed its first competitive utility solar procurement in 2020 — a 10MW facility at Trents — and then used the track record, regulatory framework, and financing relationships established in that first procurement to quickly scale to a second and third project. Each successive procurement was completed faster and at lower cost than the previous, as the institutional knowledge base and investor familiarity with Barbados's regulatory environment improved. This learning curve dynamic is one of the strongest arguments for Antigua completing its first utility-scale procurement as soon as possible, even if the first project is smaller than ideal.
The Role of Net Billing and IFC Financing
Barbados's 15MW of residential solar is directly attributable to its robust net billing program, which provides 1:1 credits and has a residential system size cap of 25kW. The program was designed with IFC technical assistance and financed in part through the IFC's Solar Rooftops Program, which provided guarantees to Barbadian commercial banks making solar loans — reducing the risk premium that banks charge and lowering effective interest rates for homeowners. The combination of a clear, functioning net billing policy and IFC-backed financing for residential customers created the market conditions for rapid uptake.
Barbados also benefited from its utility, BL&P, taking a more cooperative stance toward distributed solar than APUA has historically shown. BL&P's management recognized that solar adoption could reduce the utility's fuel cost exposure — its largest and most volatile cost — and worked with regulators to design interconnection standards and net billing mechanics that facilitated rather than obstructed customer installations. The contrast with APUA, which has been slower to adapt its operational practices to accommodate distributed generation, is instructive.
Antigua at ~2%: The Gap Is Wide, But the Path Is Clear
Antigua stands at approximately 2% renewable penetration — roughly where Barbados was in 2018, before the Sustainable Energy Framework took effect. The gap is 15 times Antigua's current installed capacity. Closing it by 2030 is theoretically achievable — four years is enough time if the right decisions are made immediately — but it requires urgent action on all three fronts simultaneously: a utility-scale procurement, enacted net metering regulations, and accessible residential financing. Barbados managed all three within an 18-month window between 2019 and 2021. There is nothing uniquely difficult about Antigua's situation that should prevent the same.
The political economy in Barbados was different in one important respect: Prime Minister Mottley made renewable energy a personal priority and wielded her political capital to push through the Sustainable Energy Framework over internal government resistance. Equivalent political will at the highest levels of Antigua's government has not been consistently visible. The upcoming public consultation on net metering regulations, the parliamentary hearings on the Renewable Energy Act, and the IDB financing negotiations are all moments where visible political commitment from Antigua's leadership would accelerate outcomes. The Barbados example shows what's possible; what remains to be seen is whether Antigua chooses to follow it.
