The measure in question is a bill that will have to be approved in Parliament that aims at reducing the so-called "benefits from heaven" obtained by energy producers with low CO2 emissions (such as nuclear energy) that - due to current market mechanisms - manage to sell energy at prices similar to those who have to pay the European CO2 emission rights, thus obtaining higher profits.
This initiative has put the main companies in the sector in Spain on a war footing, including large electricity companies such as Endesa and Iberdrola.

Current concessions will expire between 2027 and 2035, said Spanish daily El País.

Government sources told the sector that the planned measures are "in accordance with national and European law", according to Spanish public broadcaster TVE.
