The transmission grid operator is obliged to transmit electricity from renewable energy sources (§ 13 par. 1 Electricity Market Law). It shall not discriminate between or against producers of electricity from renewable energy sources. The amount of electricity to be transmitted may be limited only in case of insufficient grid capacity or emergency.
