Evaluation of the Energy Efficiency Fund

The Energy Efficiency Fund is a special budget of the German Federal Ministry of Economic Affairs and Energy for the support of energy efficiency measures in industry, business, transport and households. The policies range from broad-range financial support programmes and individual support to information and consulting measures and labelling initiatives. The goal of the project is to develop a methodology for the policy set and to apply it for the roughly 20 policies. Furthermore policy recommendations for the enhancement of the fund are being developed.

The Energy Concept of the German Federal Government, the so-called Energiewende, contains, among expansion of renewable energy generation, ambitious goals for energy efficiency. Among others, primary energy consumption is set to be reduced by 20% until 2020 and 50% until 2050. Electricity consumption is set to be reduced by 10% until 2020 and 25% until 2050 (each compared to the base year 2008). Based on the „Law for the installation of a special budget for energy and climate“ (EKFG) from December 2019 (BGBI. I, S. 1807), the Energy Efficiency Fund was established in 2011.

Both as a working basis for the improvement of the German energy efficiency policy and for national and European reporting obligations, the goal of this project is to conduct a full evaluation of the Energy Efficiency Fund. In this context, the fund as a whole as well as each of the single policies should be evaluated and policy recommendations should be formulated. For the evaluation the three basic dimensions foreseen in § 7 of the Federal Budget Regulation (BHO) are employed: target achievement, impact assessment and economic assessment.

As a basis for evaluation, at first an evaluation system was developed and continuously adapted to the methodological challenges of evaluating the Energy Efficiency Fund. The methodological concept was structured in such a way that it takes account of the variety and heterogeneity of policies financed by the fund. Hence, the system establishes a common development of evaluation. It is structured in three main sections: goals, indicators and methods. In the goals section, the goals of the fund as a whole as well as each of the single policies are collected. This way, the goals of the single policies are directly related to their contribution to the goals of the Energiewende. In a second step, indicators were developed that could measure the target achievement, impacts and economical factors. Furthermore the programme administration is analysed. In the methods section, necessary data for the evaluation and systems of data collection are defined. Results can be found in the publications and will be added shortly.
