Reform Options for Default Electricity Supply
Study by FfE for Octopus Energy
The current design of default electricity supply in Germany is facing increasing challenges, as price and tariff structures respond only to a limited extent to the dynamic developments of the energy market. Against this backdrop, the present study, commissioned by Octopus Energy, analyzes the regulatory framework governing default and substitute supply in Germany as well as in selected European comparison countries. The objective is to systematically categorize different regulatory approaches and derive potential pathways for further development of the German framework.
The analysis of reform options shows that the future of default and substitute supply does not lie in a single “go-to” solution, but rather in the smart combination of effective reform components. Each option comes with specific strengths, but also with trade-offs, structural limitations, or implementation requirements. Ultimately, regulatory design determines impact and efficiency. The study highlights that reform potential primarily lies in greater transparency, stronger cost pressure through competitive tendering mandates, and a clearer separation between social protection mechanisms and the market-based mass retail segment.
Key Take-Aways
- Need for Reform of Default and Substitute Supply in Germany
The current design of default and substitute electricity supply in Germany shows a clear need for reform. In particular, there are deficits in transparency, efficiency, and competition. As a result, default tariffs are typically priced above competitive market offers, disproportionately burdening low-income households. - Leverage Competition Strategically
Competitive tendering can be an effective instrument to increase cost and margin pressure in default and substitute supply – provided it is supported by careful regulatory design. - Separating the Electricity Market and Social Policy
Consistently shifting the protection of vulnerable households out of the electricity market framework can strengthen targeted consumer protection while relieving the competitive mass market of social policy risks.
- Transparency as a Cross-Cutting Lever
Greater transparency in costs, pricing, and responsibilities is a key prerequisite for better aligning competition, cost reflectivity, and social targeting within Germany’s default and substitute electricity supply system.
Project Structure
Qualitative analysis of the regulatory framework for default and substitute electricity supply in Germany and selected European countries. Based on this, derivation and comparative assessment of reform options against key evaluation criteria.
Results
Each reform option entails specific strengths, but also trade-offs, structural limitations, or implementa-tion requirements. Ultimately, regulatory design determines impact and efficiency. The assessment therefore speaks less in favor of a single reform option and more for a modular reform approach that combines compelling elements of different models.
A particularly promising pathway lies in strengthening competitive elements, especially through tendering mechanisms.
A second key reform element is the consistent separation of social protection measures from the competitive mass retail market.
Overall, the analysis shows that greater transparency, stronger competitive cost pressure, and targeted social protection for vulnerable households are central levers for further developing default and substitute electricity supply.
