Banco Santander stock presses Brussels for power-grid rule changes

Banco Santander has asked the European Commission to adjust energy-market rules so private capital can help finance large electricity interconnections between EU member states. Cinco Días reported the proposal on Tuesday, November 10, after a Santander meeting with representatives of European Commission Executive Vice-President Teresa Ribera on October 13 in Brussels.

The bank's investment-banking and public-policy teams argued that current rules do not give investors enough certainty over revenues extending beyond 10 years. Santander wants regulators to reduce the gap between non-discriminatory cross-border capacity-allocation rules and the predictable income streams required to finance infrastructure with development periods measured in decades.

Long-term revenue certainty is central

Santander said interconnections can help lower electricity prices, move surplus power between countries and integrate renewable generation. The financing challenge is significant because projects require heavy upfront investment, long construction periods and stable returns before the capital can be recovered.

The proposal calls for closer cooperation between infrastructure funds, energy companies, transmission-system operators and regulators. That structure would combine Santander's financing and advisory role with the industrial and regulatory expertise needed to develop cross-border projects.

The request comes as Brussels seeks to raise the role of electricity in final energy consumption from 23% today to 46% by 2040, according to the figures cited by Cinco Días. The European Union also aims for interconnections to reach at least 15% of each country's installed generation capacity by 2030. The Iberian Peninsula remains well below that target, with interconnection capacity between 2% and 3%.

Clean-energy financing provides a platform

Santander's position builds on earlier activity in clean-energy finance. In February 2025, the bank signed an agreement with the European Investment Bank involving a 500 million euro counter-guarantee. The arrangement is intended to support a guarantee portfolio of up to 1 billion euros and mobilize as much as 8 billion euros for European manufacturers of wind equipment and related components.

For investors, the initiative highlights Santander's ambition to expand fee-generating and advisory activity around the energy transition, but it does not by itself establish a new earnings forecast. The proposal also depends on regulatory decisions and on private investors accepting the risk profile of long-duration infrastructure projects.
