The energy self-sufficient village Feldheim

Success through cooperation
One of the most spectacular concepts for supplying enterprises, private households and local government with renewable energies on a decentralised, self-sufficient basis is currently being implemented in Feldheim, a district of Treuenbrietzen, a town in Brandenburg. The project owes its success to the excellent partnership between the municipality of Treuenbrietzen, the inhabitants of Feldheim and the project developer, Energiequelle GmbH.

The energy self-sufficient village
The individual households in Feldheim, Treuenbrietzen, are supplied with heat and power from renewable energy power plants at their own doorstep via autarchic local grids.

Energiequelle GmbH designed the various components of this concept – which includes cutting-edge, state-of-the-art wind power systems and biogas plants –, installed them as turnkey systems and linked them via the new heat and power distribution system to form a regional energy supply grid.

Reliability under peak loads
The nearby wind farm is the backbone of the local power supply grid, whereas heat is supplied by the local biogas plant. Natural fluctuations in wind power production will be balanced in future by a next-generation accumulator to be installed in a second, expansion phase of the project. A sophisticated heating plant fired with woodchips is available for additional thermal energy requirements on particularly cold days.

Independence with a private grid
What is special about the Feldheim concept are the separate grids for district heating and power supply, via which the heat and electricity produced locally are fed straight to consumers. This saves costs and achieves independence from the grids of conventional power utility companies.

Financed by pooling resources
The owner of the local district heating grid is Feldheim Energie GmbH & Co. KG, a limited partnership formed by the connected households, enterprises and the municipality of Treuenbrietzen.
The owner of the separate power grid for supplying electricity to connected consumers is Energiequelle GmbH and Co. WP Feldheim 2006 KG.

However, the municipality and the local residents were unable on their own to put up the substantial investments needed to build the separate power and district heating grids. Additional funds from the regional government and from EU programmes were therefore tapped.
