The division’s €1.1 billion in earnings before interest, taxation, depreciation and amortisation (Ebitda) was 20.6% higher than the €917 million from the same period one year ago.
Its €2.35 billion in sales was also 20.1% higher than the €1.95 billion in the first half of 2017.

It did not give a total figure for wind power output between 1 January and 30 June, however EDF EN stated that its wind power assets in France and Germany produced 14.1TWh and 55TWh respectively.
Wind power generation in France and Germany, therefore, was 3TWh and 3.7TWh more than in the first six months of last year.
These increases in generation were due to better wind conditions and the 1.68GW of new capacity brought online in 2017 and 80MW commissioned so far this year, EDF EN stated.
Increased generation also led to a boost in earnings despite lower spot market prices, the company added.
EDF EN stated that in the first half of the year "several significant periods of wind and photovoltaic power generation" led to negative prices, reaching a low-point of -€76/MWh on 1 January in Germany.
In the first half of the year, the wider EDF conglomerate, EDF Group, offshore wind project, which will be built in UK waters, with commissioning planned for 2023.

At the end of that month, it also agreed to sell a 49% stake in a 550MW portfolio of onshore and offshore wind farms in the UK.
EDF EN also rebranded most of its international subsidiaries as EDF Renewables in April in an attempt to "raise the visibility" of the company’s business overseas.
