For farmers & farm managers
Turn your farm into its own energy company.
From feeding in to earning. Electricity, heat and flexibility from a single system.

The end of guaranteed remuneration.
The KEV was a reliable source of income, but it is now being phased out. Since the end of 2022, the support scheme has accepted no new installations, and the existing contracts are expiring in stages, after 15 to 25 years, depending on the commissioning date. Installations commissioned between 2010 and 2013 are among the first affected. After that, market conditions apply. Minimum remuneration exists only for installations below 150 kW, falling from 6 centimes at 30 kW to 1.2 centimes at 149 kW. A typical barn roof may exceed that threshold and may no longer have a minimum floor. From 2027, remuneration is expected to follow the hourly spot-market price. At midday in summer, when installations produce the most, electricity may be worth very little and can sometimes have a negative price. The grid operator may also curtail up to 3 per cent of production without compensation. Feeding electricity into the grid is therefore becoming a less reliable business model.
Your farm has what it needs for the next energy business.
Few operations have better conditions. Large roof areas, an existing PV installation, genuine electricity and heat demand on the farm and often a heating network for the neighbourhood. What is missing is storage that turns midday electricity into evening and winter electricity. The battery shifts electricity across hours, from midday into the evening, and can earn on the spot market and through flexibility. Hydrogen long-duration storage system shifts energy across seasons, from summer into winter, and delivers electricity and heat. Since 2026, you can also sell electricity directly to neighbours in the municipality through Local Electricity Communities, with a discount on grid usage. eRevo AG Energy Revolution is the pioneer of decentralised multi-energy systems in Europe and plans on a technology-neutral basis. Battery, hydrogen or both, the analysis shows what your farm needs.

How much can your farm earn?
Your energy should earn money, not cost it. Five levers can turn the expiring KEV into a stronger business model.
Self-consumption
Every kWh of self-generated electricity saves on purchased power. Barns, cooling, drying, machinery and heat pumps can run on your own electricity instead of more expensive grid electricity. Storage can substantially increase self-consumption, and your buyers and labels are increasingly asking about carbon footprints. Electricity from your own roof, stored and used on-site, is a straightforward answer.
Electricity for the village
Sell to the neighbourhood. Through Local Electricity Communities, you can supply electricity to households and businesses in the municipality at your own tariff and with a discount on grid usage.
Spot market and flexibility
Your storage participates in the market. The battery stores electricity when it costs little and delivers when it is more expensive. Your flexibility can also earn revenue on the market.
Heat
Earn twice from the same system. Heat for the barn, farmhouse and drying can come from both operating states, during charging through waste heat from the electrolysis and during discharge through the fuel cell. Operators of heating networks can sell the heat onwards.
Cheaper procurement
Enter the free market. From annual consumption of 100 MWh, you can choose your supplier and gain access to tariff models that reward flexibility.
From farmer to energy farmer.
Your farm may already produce more energy than it needs. With storage, that surplus can become a business. Electricity for the village, heat for the network and flexibility for the market. Procurement changes too. New tariff models from large energy suppliers combine energy supply and flexibility and reward the capabilities your farm can provide. Figures under discussion are 14 to 20 centimes per kWh including grid fees, with electricity costs in some cases close to zero. The prerequisites are annual consumption of over 100 MWh and procurement on the free market. With storage, a heat pump and electrification, both may be within reach.
We remove complexity and improve profitability.
One system, one point of contact.
Design, planning, partners and business models from a single source. Battery storage comes from our partners, and our system architecture includes short-duration storage where appropriate.
Technology-neutral planning.
We do not sell a technology. We sell the energy system that can pay off for your farm. The recommendation follows the analysis.
Proven in live operation.
The world premiere installation in Eich has been operating at full load since April 2024. Six years of development work have made eRevo AG Energy Revolution the pioneer of decentralised multi-energy systems in Europe.
