The Ökostromgesetz (Green Electricity Act), which came into force on 1 January 2003, introduced a national system for renewable electricity support payments. The act made E-Control responsible for monitoring attainment of the system's objectives.
The green power support scheme affects market participants in a variety of ways. Electricity suppliers are allocated supported renewable energy. System operators must adapt to the volatility of wind power output.
The financial means for supporting green electricity also come from market players or consumers.
