EU member states should quickly decide about a proposal by the European Commission to cap renewable energy revenues at €180/MWh ($173/MWh), and ensure the measure is only temporary and not retroactive in nature, the wind sector warned at the opening of WindEnergy Hamburg.

The commission earlier this month had proposed the cap on power price revenues of renewables, nuclear and lignite power producers and a ‘solidarity contribution’ from the oil & gas sector.

The two measures are slated to raise more than €140bn for EU member states to cushion households and businesses from sky-high energy prices in the wake of Russia’s invasion of Ukraine.
