E-CO Energi reports a strong first half

E-CO Energi earned a consolidated net profit in the first half of 2018 (H1) of MNOK 595, up MNOK 168 from H1 2017. The improvement in performance must generally be seen in the light of higher selling prices and the acquisition of Hafslund Produksjon in August 2017. Adjusted for unrealised results on price hedging contracts the net profit was MNOK 796, an increase of MNOK 418 from H1 last year.

Hafslund E-CO Corporate Management appointed

The Hafslund E-CO group was established 4 July this year. The newly appointed Board og directors appointed Finn Bjørn Ruyter as Chief Excecutive Officer (CEO). The Corporate management has now been appointed.
