The demolition of the Lough Ree Power Station has been approved by Longford County Council.
The ESB applied for permission to take the Lanesboro plant down earlier this year and replace it on site with a battery energy storage system.
Plans include the installation of the storage system and a Synchronous Condenser following the demolition of the substantial structure to ground level.
The planned demolition will include the boiler house, turbine house, bag filter house and associated 80 metre high stack among other structures.
The peat burning station in Lanesboro was shut in 2020 following 62 years of electricity production.
The demolition has been criticised by some locals, with submissions to the Council raising concerns over the destruction of energy infrastructure during what was called the ongoing energy crisis in Europe.
While another submission highlights a concern of fire at the battery energy storage facility.
The plans have been approved by county planners with 15 conditions attached.
