Major Solar and Battery Project Proposed for Potworks
Cabinet directs Chinese engineering firm to consult APUA on a detailed proposal for a 30-megawatt peak solar facility with battery storage.
A proposed solar energy and battery storage development at Potworks could generate between 49.5 and 54 gigawatt-hours of electricity annually, adding a substantial source of renewable power to Antigua and Barbuda’s electricity supply.
China CAMC Engineering Co., Ltd. (CAMCE) presented the project to Cabinet, outlining plans for a 30-megawatt peak solar photovoltaic facility supported by a 15-megawatt battery system with 30 megawatt-hours of storage capacity.
Cabinet has not granted final approval. The company has been directed to engage with the Antigua Public Utilities Authority (APUA) to develop a comprehensive technical and financial proposal for further consideration.
The preliminary design includes approximately 48,384 solar panels, each rated at 620 watts, and 54 inverters rated at 460 kilowatts each.
The battery system would store electricity produced during daylight hours for use when demand increases, particularly in the evening. At its rated output, it would provide a nominal two hours of storage, helping APUA manage supply and integrate more solar power into the national grid.
Cabinet was advised that the development could reduce dependence on imported fossil fuels, limit exposure to international fuel price fluctuations and strengthen the country’s long-term energy security.
However, further discussions must establish how the proposed facility would connect to and operate within the existing electricity network.
The detailed submission is expected to address financing, technical specifications, construction timelines, grid integration, operational requirements and anticipated economic benefits.
Cabinet emphasised that APUA’s involvement is essential to ensuring the project is compatible with existing infrastructure and aligns with the authority’s long-term generation and distribution plans.
The proposal forms part of the government’s wider efforts to diversify the national energy supply through solar power, battery storage and other renewable technologies.
Further consideration will follow the submission of the comprehensive proposal developed in consultation with APUA.
