The ESB is to sell its Lough Ree and West Offaly peat power plants.
The semi-state is in the process of selling a number of assets, which it has determined to be "non-strategic", at the request of government.
It's already proceeding with the sale of the Marchwood plant in the UK and Bizkaia Energy in Spain.
Those two disposals will not meet the €400m target set by the government in October 2012 as a special dividend from the ESB asset sales. As a result ESB has determined it will now sell the two peat plants.
The company also announced a fall in half-year profit-after-tax to €188m. Turnover for the six months to the end of June was 4% higher at €1.7 billion. Higher revenue combined with a 12% reduction in payroll costs saw ESB's operating profit rise by €50m over the period.
ESB chief executive Pat O'Doherty said the €45m drop in after-tax profit was due to "higher interest rates and tax changes".
