The efficiency of a BlueGEN greatly depends on your consumption pattern. Please contact one of our customer advisers for an individual efficiency analysis. As the savings achieved in the power supply are greater than the remuneration from the feed-in tariff, you will achieve maximum cost-effectiveness if you yourself consume as much of the electricity you produce as possible.
As the savings achieved in buying electricity are greater than the remuneration from the feed-in tariff, you will achieve maximum efficiency if you yourself need more than 13,000 kWh of electricity a year and thus yourself use as much of the electricity you produce as possible.
You can choose between a remuneration in accordance with KWKG (German CHP Law) or EEG (German Renewable Energy Sources Act). Biomethane is required to operate the BlueGEN in compliance with the German Renewable Energy Sources Act. In general the remuneration of KWKG is much more advantageous.
The European Union as well as various local governments offer funding and support for the installation of highly efficient energy appliances like BlueGEN. More information can also be found here: Subsidies. For a free and individual consultation about funding please contact us directly.
The generating costs per kilowatt hour depend on your individual gas tariff. As a rule, you can assume about 10–12 euro cents per kilowatt hour (without investment and maintenance costs).
Unlike photovoltaics, the BlueGEN does not rely on environmental factors. Instead, BlueGEN provides a constant year-round supply at a fixed output. The BlueGEN does not rely on a south-facing roof and has no impact on the building’s architecture.
