A major review of Ireland's energy supply is set to take place following recent government approval.

The review will look into the security and sustainability of the national supply as Ireland moves to 70% renewables.

Environment Minister Richard Bruton will lead the initiative, which will consider the actions needed to reach 70% renewable electricity and assess the role of gas during the transition as well as review the role that other technologies can play like battery storage and pumped storage.

Announcing the government support, Minister Bruton said: "As we phase out coal and peat and move towards generating 70% of our electricity from renewable sources, we need to make sure we are prepared for when the wind isn't blowing and the sun isn't shining. We will look at the best mix which will maintain energy security, while ensuring we are meeting our climate commitments."

The Climate Action Plan, published earlier this year, sets out over 180 actions across every sector which will ensure Ireland meets the 2030 climate commitments. Commitments to phase out peat and coal and a move towards 70% renewable electricity are central to the Plan. The government have also, following advice from the Climate Change Advisory Council, made the decision to cease exploration for oil off Irish coastal waters.

By 2030, Ireland's electricity supply will be dependent primarily on variable renewable (wind and solar) energy. The remainder is likely to be generated from natural gas - the lowest emitting fossil fuel, interconnectors and battery storage.

Minister Bruton has written to the Chairperson of EirGrid, ESB, Bord na Móna, Ervia and CRU to seek their input into the review.

"Decarbonising our energy supply is crucial. It will make a really significant impact on our emissions, especially as we electrify our car fleet and public transport systems. This review will ensure we are prepared to make the radical change that is needed," he added.
