57. Energy-Charts Talks 02.03.2026: Welche Folgen hat der Übergang vom GEG zum GMG
Summary
Dr. Veit Bürger discusses the transition from the GEG to the GMG, focusing on the implications of the proposed building modernization law. Key changes include the introduction of the 'biotreppe', which aims to gradually increase the share of climate-friendly fuels in heating systems. The law emphasizes the need for energy efficiency and outlines new requirements for buildings to meet climate goals.
Concerns arise regarding the removal of the 65% renewable energy requirement, which may lead to increased reliance on fossil fuels. The proposed regulations for biogas and biomethane face challenges due to limited infrastructure and high costs, raising questions about the reliability of energy supply. Investment decisions in the gas sector are becoming increasingly uncertain as stakeholders navigate rising fuel costs.
The biotreppe is set to start in 2009 with a 10% requirement for climate-friendly fuels, increasing in three steps. However, the effectiveness of this gradual increase is questioned, as market readiness and consumer acceptance of alternative fuels remain uncertain. The lack of new technologies in the proposed regulations may hinder the achievement of the 2030 climate goals.
Bürger highlights the importance of understanding the implications of the new regulations on building owners and the overall market dynamics. The existing technology portfolio does not introduce significant innovations, which raises concerns about the potential impact on climate objectives. The reliance on the biotreppe as the sole innovation may not suffice to meet the ambitious climate targets.

Timeline highlights
00:00–05:00
Dr. Veit Bürger discusses the transition from the GEG to the GMG, highlighting changes in energy efficiency regulations.
- Dr. Veit Bürger discusses the transition from the GEG (Gebäudeenergiegesetz) to the GMG (Gebäudemodernisierungsgesetz), emphasizing the implications of this change for energy efficiency regulations
- The GMG will introduce new regulations for communal heating planning, particularly aimed at simplifying processes for small municipalities to enhance energy efficiency
- The proposed changes will eliminate the 65% requirement for renewable energy in new heating installations, affecting both new and existing buildings undergoing modernization
05:00–10:00
The proposed 'biotreppe' aims to gradually increase the share of climate-friendly fuels, starting in 2009 with a 10% requirement and rising in three steps. This includes biomethane and synthetic fuels as alternatives to fossil fuels.
- The proposed biotreppe aims to gradually increase the share of climate-friendly fuels, starting in 2009 with a 10% requirement and rising in three steps. This includes biomethane and synthetic fuels as alternatives to fossil fuels
- Current regulations allow for gas or oil heating systems, provided they comply with the common value plan. This plan mandates a gradual increase in the use of biomethane or bio-oil, reaching 15% by 2005 and 30% by 2030
10:00–15:00
The new law introduces a technology portfolio for heating options but does not add new technologies, with the biotriple being the only significant change. Concerns arise regarding the effectiveness of this regulation in achieving the 2030 climate goals due to uncertainties in market dynamics and technology distribution.
- The new law will include a technology portfolio for heating options, but it does not introduce new technologies beyond the existing ones. The only significant addition is the biotriple, which is set to be implemented starting in 2029 with a gradual increase in its percentage
- From the perspective of building owners, the biotriple is the only new aspect, while the rest of the technology distribution remains unchanged. This raises questions about the effectiveness of the new regulation in meeting the 2030 climate goals
- There is uncertainty regarding the market volume and the distribution of technology under the new regulation. Current market dynamics suggest that gas exchange values are likely to dominate, but the extent of this shift is unclear
- The quotas for green gas and green hydrogen are limited, posing challenges for meeting climate goals. The costs associated with climate-friendly fuel stations are also uncertain, creating a risk for future investments
- The minimum values for achieving climate goals in buildings highlight the 65 percent demand, which is crucial for compliance. Current proposals may not adequately address the necessary compensatory measures to meet these targets
- Questions remain about the production and sourcing of biogas, including the origins of COE and the implications of relying on imports. This raises concerns about energy independence and the sustainability of the proposed solutions
15:00–20:00
The transition to biogas and biomethane is hindered by limited infrastructure and high costs, raising concerns about energy supply reliability. Investment decisions in the gas sector are increasingly uncertain due to rising fuel costs and future regulatory impacts.
- The transition to biogas and biometan faces challenges due to limited biometan networks and the complexities of converting biogas, which requires significant infrastructure and investment. This raises concerns about the sustainability and reliability of energy supply
- Rising fuel costs create a pressing cost risk for businesses in the gas sector, leading to uncertainty in investment decisions. Future regulations, particularly those related to the biotriple, will significantly influence these investment strategies
