Marked rebound of the operating performance... Hydropower output in France amounted to 46 5TWh (1), an increase of 25 4 % (+ 9.4TWh) over 2017 . After a very dry year in 2017, 2018 benefited from good hydropower conditions and an optimised availability of hydropower assets... The financial result corresponds to a financial expense of euros 4 8 billion, euros 2 6 billion more than in 2017 . This evolution is primarily due to the change in the fair value of debt and equity on dedicated assets, which weighs on the financial result (application of IFRS)9 (2) because of unfavourable market conditions, especially at the end of the year.
