The sale encompasses an annual volume of 680 gigawatt hours and covers the period through the end of 2020. The transaction will be closed by the end of February.The background for the sale is the fact that Norske Skog after the closure of Follum paper mill has a contract for larger power volumes than needed by the group's plants in Norway. After the sale, the contract is aligned with the company's needs going forward."The power we now sell was originally acquired through a long-term, commercial contract in a market with lower power prices than today. When the situation is such that we no longer need as much power, it makes sense to sell it, in order to focus on running our manufacturing business," says Sven Ombudstvedt, CEO of Norske Skog.
