German Cabinet Drops Green Heating Law, Revamps Energy Investment Rules

By Christian Kraemer and Holger Hansen

German Government Overhauls Energy and Heating Policies

BERLIN, May 13 (Reuters) - German Chancellor Friedrich Merz's cabinet agreed on Wednesday to scrap a contentious heating law and pass measures to boost long-term power generation capacity as it pledged to push on with a package of reforms to revive the struggling economy.

Background and Rationale for Policy Change

Economy Minister Katherina Reiche said replacing the 2023 law that required new building heating systems to use at least 65% renewable energy would ease the way for companies to invest in construction and building restoration.

"With it, we are creating investment security, we are creating planning security, we are enabling technological openness and flexibility in the choice of heating system," she told reporters.

New Measures to Support Power Generation

In addition to the draft heating law, the cabinet approved the creation of a market for standby power generation capacity to back up renewables as coal power generation is phased out, according to government policy.

Standby Power Market Details

Under the proposals, operators of power stations or storage facilities would be paid not only for the electricity they supply, but also for keeping capacity on standby for use when renewables are interrupted in periods of low wind or sunshine.

Political Context and Reform Challenges

The measures were agreed as the coalition struggles to reverse a sharp slide in its approval ratings that has deepened during months of wrangling over long-promised reforms to the tax, pension, health and welfare systems.

Country Aims for Climate Neutrality by 2045

In the face of surging support for the far-right Alternative for Germany party (AfD), Merz's conservative Christian Democrats (CDU) and their centre-left Social Democrat (SPD) coalition partners have both pledged to set aside differences and focus on concrete reform steps.

Details of the Scrapped Heating Law

The heating law, passed under the government of former Chancellor Olaf Scholz, drew opposition from conservatives and some media over fears it would force households to scrap gas and oil heaters and spend thousands of euros on new green systems.

Replacement with Building Modernisation Law

Under Wednesday's agreement in cabinet, the law will be replaced by a new building modernisation law that will drop the requirement to include mandatory renewables elements. Households will be allowed to keep existing boilers if they do not choose to switch to alternative systems like heat pumps, district heating and biomass systems.

Gradual Transition to Climate-Neutral Fuels

The new law, which the government said needed to be passed before the start of parliament's summer recess, will require new gas and oil systems to gradually blend in climate-neutral fuels from 2029, increasing their level from 10% to 60% by 2040.

Alignment with EU Directives and Climate Goals

The law, which reiterates Germany's commitment to achieve climate neutrality by 2045, will also implement the European Union's Buildings Directive mandating all new buildings to be zero-emission from 2030.

Reactions from Industry and Political Parties

Germany's BDI industry federation welcomed the change as "an important step towards finally getting investment back on track" and said it would provide a boost to refurbishing Germany's building stock and putting money into construction.

But it was heavily criticized by the Greens' parliamentary leader Katherina Droege, whose party was the driving force of the heating law when it was in government with Scholz, as "a complete abandonment of Germany's climate targets."

Key Takeaways

  • The 2023 ‘heating law’ requiring 65% renewable energy in new heating systems will be abolished under the new Building Modernisation Act, restoring technological and investment flexibility for homeowners and businesses.(energynews.oedigital.com)
  • The reform introduces a gradual green gas quota (‘Bio‑Treppe’) for new gas and oil systems: starting at 10% green fuels in 2029 and increasing to 60% by 2040, aligning with Germany’s 2045 climate neutrality target and EU’s zero‑emission building rules.(energynews.oedigital.com)
  • While industry groups like BDI praised the reform for improving investment certainty, environmentalists and the Greens criticized it as undermining climate ambitions by diluting binding renewable mandates.(energynews.oedigital.com)
