Guyana is rapidly advancing its energy infrastructure development to accommodate unprecedented growth in electricity consumption, with officials outlining ambitious plans at the recent Guyana Energy Conference. The 300-megawatt natural gas-fired power plant at Wales is projected to achieve full operational capacity by mid-2026, according to Ministry of Natural Resources Consultant Winston Brassington. The facility, currently under construction by Texas-based contractor LINDSAYCA, is expected to initially generate 228 megawatts through its four simple cycle gas turbines before reaching maximum output with combined cycle completion. This development coincides with Guyana’s significant grid modernization effort, transitioning from 69 kV to 230 kV transmission systems to handle what officials describe as ‘explosive growth’ in electricity demand. The new transmission infrastructure already extends from Wales to Eccles, with additional substations and control centers scheduled for completion by May. Guyana Power and Light CEO Kesh Nandlall revealed that electricity consumption has surged by 65% over five years, from 903 gigawatt hours in 2020 to 1,485 gigawatt hours in 2025. Current peak demand reaches 221.5 megawatts against available reliable capacity of 260 megawatts. With projections indicating demand could reach 1,650 megawatts by 2030—requiring a 600% capacity increase—authorities are already planning a second gas-to-energy plant at Wales. Five firms have been prequalified for this expansion, which will include urea fertilizer production and glass manufacturing facilities.
