The responsibility for implementing the Energy Efficiency Directive in Germany lies with the German Federal Ministry for Economic Affairs and Energy (BMWi). Furthermore, the Federal Ministry of the Interior, Building and Community (BMI) and the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) are involved in the implementation of selected areas of the directive.
The Federal Energy Efficiency Center (BfEE) within the Federal Office for Economic Affairs and Export Control (BAFA) fulfils reporting and monitoring, as well as communication activities. The BfEE also selects and oversees institutions which conduct energy efficiency research for the ministries. Provisions in the Energy Efficiency Directive concerning the energy market and grids lie within the responsibility of the Bundesnetzagentur (BNetzA). Several organisations, namely the BAFA, the KfW and different project executing bodies implement energy efficiency measures, initiatives and programs on behalf of the ministries.
