In 2009 the KfW consolidated their support programmes for renewable energy investments. One single programme superseded the following programmes: Producing Solar Power, ERP-Environment and Energy Saving Programme, KfW Environment Programme, KfW-Programme Renewable Energy. The new KfW Renewable Energies Programme consists of two parts - "standard" and "premium". The "standard" programme part comprises loans for: - Electricity from solar energy (photovoltaics), biomass, biogas, wind energy, hydropower, geothermal energy; - Electricity and heat from renewable energies, generated in combined heat and power (CHP) stations. The "premium" programme part offers loans and repayment bonuses for heat from renewable energies generated in large plants. In addition, there is a programme part "Deep Geothermal Energy", ficing facilities for the development and utilisation of hydrothermal and petrothermal deep geothermal energy with more than 400 m drilling depth. With effect from 15 August 2012 the support guidelines in the premium part of the programme were modified, improving support for large solar collectors, large heat pumps, biogas pipelines for certain applications and deep geothermal plants. Funding will no longer be available for heat grids and heat accumulators that benefit from more favourable conditions under the amended Combined Heat and Power Act, which entered into force on 19 July 2012.
