Brussels asks Spain to end the regulated electricity rate
The European Union is reforming the energy market and wants Spain to prepare a plan to progressively eliminate the regulated price of electricity, according to a report from the European Commission. The European body believes that this system should be only for specific cases.
The regulated rate is the one that directly affects thousands of people and homes throughout the national territory. Well now, the Commission insists that regulated tariffs should only be maintained to protect vulnerable consumers or in exceptional situations.
