Farmers planning a renewable electricity project could see application fees to connect to the national grid multiplied by up to 20 under proposed rules included in a current public consultation ending this Friday. The application fee currently ranges from €763 to €8,841 for projects of 11kW to 4MW, which is the size of farm-scale wind turbines, rooftop solar panel arrays or biogas plants. Up to €7,000 must be paid upfront as a non-refundable deposit.
