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.
EDF EN stated the increased earnings in its renewables unit was due to higher wind, solar and hydro generation.
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.
Meanwhile, contracts for three projects off the coast of France, which are being developed by an EDF EN-led consortium, were also confirmed in June — albeit at a reduced tariff.
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.
