The Romanian government has not yet approved a renewable energy law that would provide state aid through green certificates due to concerns it could significantly increase electricity bills. The renewable energy association AREE estimates the price impact would be 4.76% while the government fears an 8% increase. The legislation is meant to support renewable energy projects and investors by allowing them to sell green certificates in addition to the energy produced, but the national energy regulator estimates the policy could make Romanian electricity bills 10 billion euros higher by 2020.
