Renewable energy generated a record 14.6 terrawatt-hours (TWh) of electricity in Germany in October, according to Internationales Wirtschaftsforum Regenerative (IWR) Energien.
The research institute said expansion of wind energy and favourable weather conditions led to the October record, beating the previous record in March when 12.5TWh was generated.
Wind generated 12.5TWh last month, with 2.2TWh coming from offshore installations, IWR said.
Storms at the end of the month helped to set new records for wind output, with 39,200MW fed to the grid between 7pm and 8pm on 28 October, it added.
Solar contributed 2.1TWh of electricity, up 27% on the same month last year.
Wind and solar output in October was up 56%, on September, IWR said.
The institute said it used data from transmission system operators and the Entso-e platform.
