The electricity certificate is a market-based support system for renewable electricity production. The system came into force on 1 May 2003 and was intended to increase the production of renewable electricity and to make the production more cost-efficient. For each MWh produced from renewable resources, electricity producers have the opportunity to be granted an electricity certificate by the Government. The certificates can be sold on an open market to electricity consumers - mostly via electricity suppliers - who have to fulfil a quota obligation of certificated electricity. The quota is set in proportion to total electricity use. Energy-intensive industry is exempt from the requirement.
