Germany shut down 20 GW of nuclear power. Now consumers are paying billions for new gas plants 🏭

On 3 November, Germany announced the results of its first major tender for new gas-fired power plants covering 5.2 GW.

The operators will receive around 12 billion euros in capacity payments over 15 years, paid by electricity consumers, and according to Germany’s own regulator, Bundesnetzagentur, Germany will need between 22.4 and 35.5 GW of additional dispatchable capacity by 2035.

Meanwhile, Germany has phased out its entire nuclear fleet of 17 reactors, amounting to around 20 GW of installed capacity.

The new gas plants will not only be paid for being available. They will also be able to sell electricity into the wholesale market. That means consumers will both fund the plants through the capacity mechanism and pay market prices when they generate electricity.

And because of the merit-order principle, gas can account for a relatively small share of electricity generation while setting wholesale prices in a much larger share of hours. A recent analysis by the European Central Bank (ECB) highlights how nuclear power in France has helped reduce the frequency with which gas sets electricity prices.

Before anyone points out that wind and solar have helped phase out fossil fuels in Germany, I agree. Renewables have made a substantial contribution to reducing fossil fuel generation. My criticism is directed at Germany's decision to shut down 20 GW of existing low-carbon nuclear capacity.

By shutting down low marginal cost nuclear power, Germany has increased the need for other sources of firm generation. That leaves gas and coal setting the power price more often than if the reactors had stayed online.

As we speak, Germany and neighbouring countries are facing a prolonged Dunkelflaute, with electricity prices reaching levels otherwise associated with the energy crisis in 2022. Many are quick to point to the Hormuz crisis and Europe’s continued dependence on Russian gas, which are real factors. But we should also remember that Europe has helped put itself in this position. When perfectly functional nuclear power plants are shut down, they have to be replaced by something.

We now see this clearly in Germany. The country removed a large source of reliable, low-carbon electricity and is now paying billions to replace part of it with gas.

Vestas CEO opens the door to nuclear power in Denmark 🇩🇰

Vestas CEO Henrik Andersen has raised the possibility that nuclear power could become part of Denmark's future energy supply.

In a recent interview by Casper Schrøder on DR - Danmarks Radio , Andersen points to renewables and nuclear power as the two main energy sources Europe can expand to reduce its dependence on fossil fuels. And he explicitly acknowledges that nuclear power could also become a solution in Denmark.

The important word here is could. Andersen is not saying that Denmark should build nuclear power plants. He is pointing out that we need to be realistic about how quickly alternative energy sources can be developed before phasing out existing oil and gas production.

As Andersen has repeatedly pointed out, Europe still imports more than half of the energy it consumes. According to Eurostat, 57% of the EU’s energy needs were met by imports in 2024, primarily fossil fuels. And looking at Denmark, we still get around 50% of our total energy supply from fossil fuels.

If Europe wants to become more energy independent before 2050, we need all hands on deck that is renewables and nuclear energy.

Denmark has been a frontrunner in wind energy for decades, and renewables will continue to form the foundation of our energy system. Nuclear power could potentially complement wind and solar, providing reliable, low-carbon electricity and helping reduce our dependence on imported fossil fuels.

This is why I believe Denmark should remove its existing ban on nuclear electricity generation and the decision to exclude nuclear power from our energy planning. Doing so would allow nuclear power to be evaluated alongside other technologies based on its economics, safety and contribution to the overall energy system.

We need as much homegrown clean energy as we can get if we are serious about reducing our dependence on imported fossil fuels. That means continuing to expand renewables while keeping the option of nuclear power open in Denmark.

Nuclear power could make wind power more profitable in Denmark ⚛️🌬️

Yesterday, we brought together more than 100 professionals from across the energy sector, industry, research and politics for Danish Nuclear Alliance’s conference in Copenhagen and the launch of a new energy system analysis by Quantified Carbon.

One of the more interesting findings from the analysis is that nuclear power could actually improve the economics of wind power in Denmark.

As more wind turbines are built, they increasingly produce electricity at the same time, driving down prices precisely when they have the most electricity to sell. The analysis finds that introducing nuclear power into the electricity mix can improve the prices received by wind producers, potentially reducing the need for government support.

At the same time, nuclear power can strengthen security of supply and reduce Denmark’s dependence on electricity imports during periods of low wind and solar generation.

The analysis also examines the economic risks associated with different electricity mixes, including the uncertainties surrounding nuclear construction costs and project delays.

At today’s conference, Anton Såmark Roth, Head of Projects at @Quantified_C, presented the analysis and its findings, while @CarlBerglof, Sweden’s National Nuclear Power Coordinator, shared insights into Sweden’s efforts to develop new nuclear power.

We also had a political panel discussion with @L_Aagaard (Moderaterne), @SteffenFrolund (Liberal Alliance), Mathilde Hjort Bressum (Venstre) and @MalteLarsen_ (Dansk Folkeparti) on the potential role of nuclear energy in Denmark.

A lot of work has gone into preparing both the analysis and today’s conference, and I’m really pleased that we could bring together so many people to discuss Denmark’s future energy system.

A big thanks to all the speakers, panellists and participants who joined us today, and especially to the team at Quantified Carbon for their work on the analysis.

The analysis is now available on Kernekraftalliancen’s website. See the comments below.
