Renewable energy developer Strategic Power Projects has received planning approval for a renewable project site in Movallet in Co Louth.
When it is completed, the facility will generate 125MW of solar energy and 285MW of battery storage.
With 1.5 gigawatts of battery storage now in planning and subject to grid connection on the island of Ireland, Paul Carson - the managing director of Strategic Power Project - said that Ireland is now beginning to move in the right direction.
SPP has a substantial pipeline of projects, including solar and battery in both the Irish Republic and Northern Ireland.
Paul Carson said he is encouraged that the Government's Climate Action Plan is now having an impact on the speed of planning decisions for nationally important renewable energy installations.
"This is one of Ireland's largest solar and battery installations, so it will make a significant contribution to the national energy generation and storage infrastructure," he said.
"We all know the challenges which face the country, north and south. Energy prices have gone through the roof, security of supply is an ongoing concern and we have stringent and legally binding carbon emissions targets to reach," he said.
"It looks like the Government's efforts to draft and implement legislation to speed up the countries' response to the energy crisis are bearing fruit. I now look forward to further developments, including the Government’s proposed electricity storage policy framework," he added.
