The Tánaiste has called on the ESB to resolve an ongoing dispute over a wind farm which has seen the European Commission levy daily fines of €15,000 since 2019.
Leo Varadkar said controversy over the Derrybrien Wind Farm in Co Galway is a "long-running saga" which has been "going on for far too long".
He told the Dáil that the ESB "haven't covered themselves in glory", adding, "I really think that they need to resolve this question quickly".
Mr Vardakar was responding to Fine Gael TD Ciaran Cannon, who noted that cumulative fines of €13.2m have already been paid by the State.
The 70-turbine development on the Slieve Aughty mountains was built and is operated by a subsidiary company owned by the ESB.
During the construction phase in 2003, a massive landslide occurred, pushing thousands of cubic metres of peat down the mountain.
In 2019, the EU's Court of Justice found Ireland was in breach of environmental safeguards in relation to the construction of the wind farm.
Galway County Council then told the ESB to seek Substitute Consent - effectively retrospective compliance with the EU Directive on Environmental Impact Assessments.
However, An Bord Pleanála determined that remedial works carried out since the landslide did not "fully mitigate the significant environmental effects" that occurred.
It says the extent of the damage was "clear, profound and unacceptable" and cannot be fully mitigated.
The board was of the view that early stage construction works had contributed to unacceptable direct or indirect impacts on the environment. Works carried out after the landslide did not render these impacts acceptable.
