Longford County Council has given the green light for a battery-energy storage facility in Cloondara.
One objector claimed the plant could cause death or a serious injury.
This battery energy storage facility is planned for a one-acre site in the townland of Ballykenny.
Ion Renewables asked Longford County Council for planning permission for 18 20-foot containers and five medium voltage transformers.
The application also includes a single-storage substation building.
There were two submissions lodged.
One person, from Naas, Co Kildare, claimed the plant could overheat, release toxic gas, and cause a lethal fire.
She claimed this could cause a death, serious injury, or long-term health problems.
But the council has given the plant the go-ahead, with 10 conditions - including payment of a development contribution of nearly €126,000.
