Statkraft Shelves Wind Projects in Norway, Cites Unprofitability
Lower power and electricity certificate prices in the Nordic region have made two wind power projects in Central Norway—with a combined capacity of 1 GW—unprofitable, Statkraft said in June as it announced it would scrap them. Norway produces the bulk of its power from hydropower (Figure 3), but the country’s government has encouraged wind farm […]
