In Feldheim, a tiny village about 80 km from Berlin, electricity bills are an afterthought. Gaming enthusiast Jens Neumann says his household bill has more than halved since he moved there in 2024. Where average German prices once spiked close to €0.45 per kilowatt-hour during Europe’s energy crisis after Russia’s invasion of Ukraine, Feldheim has kept its consumer price at roughly €0.12 — far below the national norm.
The village’s energy story began in the early 1990s when engineering student Michael Raschemann spotted Feldheim’s favorable wind and slightly elevated terrain. He proposed installing four turbines, and that early project sparked wider interest. Raschemann and his wife later founded the renewable company Energiequelle and worked closely with the local agricultural cooperative and municipal leaders to expand capacity. Community consultations — from turbine siting to avoiding shadowing on houses — helped build trust and acceptance, according to cooperative head Sebastian Herbst.
Wind was only the start. In 2008 the cooperative partnered with Energiequelle to open a biogas plant that converts manure, maize and grain residues into electricity and heat while capturing methane that would otherwise escape. The system now includes solar arrays, a large battery bank and a wood-fired backup, creating a diversified, resilient mix. The village produces hundreds of millions of kilowatt-hours a year, far more than its tiny population consumes: less than 1% is used locally and the remainder feeds the national grid.
Frustrated by having to sell locally generated power back at market rates while still paying grid charges, the company and local government decided to build a new local distribution network in 2010 after attempts to buy the existing line failed. Residents each invested about €3,000 and secured state and EU funds to create an independent heating network as well. Of roughly 180 so-called bioenergy villages in Germany, Feldheim stands out as the only one with a fully independent renewable electricity and heating system.
That independence is the key to its low prices. Short distances between producers and consumers, a tight-knit community, strong local institutions and the farmers’ cooperative’s willingness to partner all made the model feasible. Similar community-run grids exist on the Isle of Eigg in Scotland and Kodiak Island in Alaska, but scaling Feldheim’s approach to larger towns or areas lacking its social cohesion and geography would be difficult.
The village also offers practical lessons: early, transparent engagement and visible local financial benefits matter. Using a small fraction of the output locally — roughly one million kilowatt-hours — helped secure community buy-in to export the remaining 99% plus into the wider grid.
Feldheim faces ongoing challenges. Subsidies for the biogas plant are expiring, replacement programs fall short of previous support, and the wind turbines will soon need upgrading. Leaders stress any major changes must again involve the community to preserve trust.
As Germany’s broader renewable expansion slows and costs remain volatile, Feldheim remains a working example of how local investment, community engagement and a diversified set of renewable assets can deliver affordable, reliable energy and sustain public support for the green transition.
