E.ON Chief Urges Households and Businesses Be Prioritized Over Renewables

Leonhard Birnbaum, chief executive of E.ON, is pressing German policy makers to rework the rules for connecting new generation to the electricity grid, saying household and business users should take precedence over new wind and solar projects. Speaking to Sueddeutsche Zeitung on December 1, Birnbaum argues that renewables already supply a majority of the country’s electricity and that continued aggressive subsidization of new capacity can raise system costs with limited additional benefit, Reuters reports.

The intervention comes amid persistent grid capacity constraints that have dogged Germany’s energy transition. Growth in wind and solar has outpaced the pace of network expansion and upgrades needed to transport power from generation sites to consumption centers. That mismatch has produced localized congestion, higher curtailment of renewables at peak output and a mounting backlog of connection requests for new projects.

Policy makers face a tradeoff. Prioritizing consumers for grid access could reduce curtailment and limit short term costs passed through to households and businesses. But it would likely slow the pace at which new renewable capacity can be added, complicating Berlin’s stated objective of reaching roughly 80 percent of electricity from renewables by 2030. Slower grid access for renewables could raise investor uncertainty, push up the cost of financing new projects and prompt higher bids in auction based support schemes.

Industry groups and renewables advocates responded with concern. Developers warn that any formal downgrading of connection priority would disrupt investment plans and could increase the cost of achieving climate targets. Grid operators and utilities emphasize the need for faster permitting for transmission lines, more storage and smarter distribution networks to reconcile the competing needs of generators and consumers.

The economic stakes are concrete. Germany has sought to integrate large volumes of intermittent generation while maintaining reliability for households and firms. When generation cannot be exported because of bottlenecks, system operators either curtail output or activate reserves, both outcomes that carry costs for producers and consumers. E.ON’s call highlights the immediate distributional question of who bears those costs when the grid is full.

Experts say the debate will likely push policy makers to consider a broader menu of options. Those could include targeted reinforcements of critical transmission corridors, faster approval processes for grid projects, market mechanisms that price congestion more transparently, and stronger incentives for storage and demand side flexibility. Each option carries trade offs between speed, cost and political feasibility.

As Germany navigates this next phase of its energy transition, the question raised by E.ON goes to the heart of energy governance. How the government balances short term affordability and reliability against long term decarbonization targets will shape investment flows, consumer bills and the shape of the power system for years to come.
