Germany is taking another step towards achieving a fully renewable power system by completing the first electric cable connection with Norway, heads of government and ministers from both states have said at the official launch event of NordLink. The green transformation cannot be achieved by countries on their own, chancellor Angela Merkel said. Integrating different energy sources in different countries, e.g. wind power in northern Germany with hydropower in Norway, is helping to ensure a secure power supply and stabilise energy prices, Merkel said. Energy minister Peter Altmaier said that the result is a win-win situation for both countries and consumers, as the energy transition would get cheaper the better European countries are interconnected.
