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 item of income. Now it is being phased out. Since the end of 2022 the support scheme has taken on no new installations, and the existing contracts are expiring in stages, after 15 to 25 years depending on commissioning. Whoever built between 2010 and 2013 is first in line. After that the market applies. A minimum remuneration exists only for installations below 150 kW, and it falls from 6 centimes at 30 kW to 1.2 centimes at 149 kW. A typical barn roof lies above that and has no lower limit at all any more. From 2027 remuneration will follow the hourly spot market price. At midday in summer, when your installation delivers the most, electricity is worth almost nothing, at times even negative. On top of that the grid operator may curtail up to 3 per cent of your production without compensation. Feeding in is no longer a business model.
Your farm has everything it needs for the business that comes next.
Hardly any operation brings better conditions with it. Large roof areas, a paid-off PV installation, genuine electricity and heat demand on the farm itself and often a heating network for the neighbourhood. What is missing is the storage that turns midday electricity into evening and winter electricity. There are two tools for this. The battery shifts electricity across hours, from midday into the evening, and earns on the spot market and with flexibility. The hydrogen long-duration storage system shifts energy across seasons, from summer into winter, and delivers electricity and heat in the process. 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 does your farm earn?
Your energy should earn money. Not cost it. Five levers turn the expiring KEV into a better business than it ever was.
Self-consumption
Every kWh of your own saves hard cash. Barn, cooling, drying, machinery and heat pump run on your own electricity instead of expensive grid electricity. Storage raises the rate massively. And your buyers and labels are increasingly asking about the carbon footprint. Energy from your own roof, stored and used yourself, is the simplest answer.
Electricity for the village
Sell to the neighbourhood. Through local electricity communities you 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 trades along. The battery stores when electricity costs almost nothing and delivers when it is expensive. On top of that your flexibility earns on the market.
Heat
Earning twice from the same system. Heat for the barn, the farmhouse and drying from both operating states, while charging from the waste heat of the electrolysis and on every cycle from the fuel cell. Whoever operates a heating network sells it on.
Cheaper procurement
Across the threshold into the free market. From an annual consumption of 100 MWh you choose your supplier yourself and gain access to the tariff models that reward your flexibility.
From farmer to energy farmer.
Your farm already produces more energy today than it needs. With storage that becomes a business. Electricity for the village, heat for the network, flexibility for the market. And procurement turns with it. New tariff models from large energy suppliers combine energy supply and flexibility and reward exactly what your farm then brings with it. The figures being discussed are 14 to 20 centimes per kWh including grid fees, in some cases even electricity costs close to zero. The prerequisites are an annual consumption of over 100 MWh and procurement on the free market. With storage, a heat pump and electrification, both are within reach.
We take complexity out and bring profitability in.
One system, one point of contact.
Design, planning, partners and business models from a single source. Battery storage comes from our partners; our system architecture needs the short-duration storage in any case.
Planned technology-neutral.
We do not sell a technology, we sell the energy system that pays off for your farm. The recommendation follows the figures from the analysis.
