The ESB Group has reported a "satisfactory performance" for the six months to the end of June as it announced a €30m dividend to the State.
The company said its profit after tax and interest fell by €32m to €141m mainly due to lower profits from its electriction generation business and higher wholesale energy costs.
Operating profits for the six months amounted to €244m, while its revenues rose by 4.5% to €1.77 billion.
Pat Fenlon, ESB's Group Finance Director, said that the company "delivered a satisfactory performance in challenging market conditions with profit after interest and tax of €141m and €499m of energy infrastructure investments".
"ESB continued to focus on delivering long term value and investing in critical long term electricity infrastructure for the benefit of our customers, shareholders and the wider Irish economy," he added.
