↑ "German grid operator sees 70% wind + solar before storage needed". Renew Economy. 7 December 2015. Dicapai 20 January 2017. Schucht says, in the region he is operating in, 42 per cent of the power supply (in output, not capacity), came from wind and solar – about the same as South Australia. Schucht believes that integration of 60 to 70 per cent variable renewable energy – just wind and solar – could be accommodated within the German market without the need for additional storage. Beyond that, storage will be needed.
