The Tánaiste has said the state will take back some of the bumper profits from the ESB.
The company reported after tax profit trebled in the first half of the year to €390 million.
The ESB is majority owned by the State and says profits are re-invested in maintaining the network, renewable energy and other infrastructure.
But Tánaiste Leo Varadkar says the government will be clawing back some of the large profits from the company.
