The nuclear energy debate in Spain
During the General Shareholders’ Meeting of Endesa, CEO José Bogas warned about the strategic risk that the closure of the nuclear park planned for between 2027 and 2035 poses for Spain. Bogas described these plants as vital assets for security of supply, economic competitiveness and decarbonization objectives, pointing out that dispensing with them prematurely would force the system to depend more on gas, which would make the bill more expensive and increase CO2 emissions.
In this sense, he urged the authorities to open a process of “reflection and dialogue” to align the closure calendar (currently planned between 2027 and 2035) “with the real pace of the energy transition, giving time for the necessary infrastructure to be developed and a fully sustainable model to be consolidated”, and aligning with the European trend of reinforcing nuclear energy as a pillar of energy sovereignty.
In fact, in the current context of the energy crisis due to the conflict in the Middle East, Bogas highlighted the role of electrification as “the only structural solution to reduce the volatility associated with imported fossil fuels.” “It is no coincidence that, even in a context of international tension, electricity prices in Spain remain among the lowest in the European Union,” he said.
