For commerce & industry
Soon you will be paying for your roof to deliver energy.
The KEV is going, the solar obligation and negative feed-in prices are coming. The DMES is your solution to that challenge.

Feeding in is becoming a loss-making business.
First the KEV goes, then prices turn negative, and the solar obligation demands more PV all the same. Many industrial and commercial roofs from the KEV years are losing their guaranteed remuneration; the contracts expire in stages after 15 to 25 years. After that the market applies, and for your installation it knows no lower limit, because above 150 kW there is no minimum remuneration. From 2027 remuneration will follow the hourly spot market price. At midday and on non-production days electricity is worth almost nothing, and at negative prices you even pay for your roof to deliver. On top of that the grid operator may curtail up to 3 per cent of your production without compensation. At the other end of the calculation you pay twice. The demand charge hangs on your quarter-hour peak, and every start-up peak in production costs money. And work goes on all year round, while your own electricity arrives in summer. Whoever does not restructure now loses on both sides.
From obligatory roof to revenue system.
Hardly any site brings better conditions with it. Large roof areas, a predictable load profile and genuine electricity and heat demand all year round. What is missing is the storage that shifts the surpluses to where they earn money. There are two tools for this. The battery caps your peak loads, shifts midday into the evening and earns on the spot market and with flexibility. The hydrogen long-duration storage system collects the weekend and summer surpluses and brings them as electricity and heat into the working weeks of winter, for hall heating, hot water and low-temperature processes instead of gas. On request we design the system so that critical processes in the building keep running during a grid outage. Our core is long-duration storage. The DMES stands quietly inside the building like a plant room, without a container outdoors, without constant noise and without objections, and delivers the heat along with it. Where a battery energy storage system (BESS) is the economic answer as a complement, we realise it with our partners. eRevo AG Energy Revolution is the pioneer of decentralised multi energy systems in Europe and plans on a technology-neutral basis.

How much do your operation and your property earn?
Your energy should earn money. Not cost it. Five levers turn the obligatory roof into a revenue system.
Self-consumption
Every kWh of your own saves the purchase price. Production, cooling, compressed air, ventilation, heat pump and charging infrastructure run on electricity from your own roof. Storage raises the rate massively, in the evening and in winter as well.
Peak Shaving
The peak determines the bill. The demand charge is based on your quarter-hour peak. The battery caps it, month after month, and noticeably lowers the grid costs.
Spot market and flexibility
Your storage trades along. Energy is stored when electricity costs almost nothing and delivered when it is expensive. On top of that your flexibility earns on the market.
Heat instead of gas
Earning twice from the same system. Hall heating, hot water and low-temperature processes from both operating states, while charging from the waste heat of the electrolysis and on every cycle from the fuel cell. Less gas, less CO2 levy.
A clean balance
Scope 2 is becoming a tender criterion. Your own solar electricity all year round is the simplest answer to your customers' CO2 questions. From around 1000 tonnes of CO2 per year, additional state funding instruments become available.
Buying electricity when it is expensive. Giving it away when it is cheap. Time to stop.
With storage you turn both sides of the calculation. Your own electricity is consumed around the clock, and selling happens only when the prices are right. And procurement turns with it. New tariff models from large energy suppliers combine energy supply and flexibility and reward exactly what your operation 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. Your annual electricity consumption is well above 100 MWh. That gives you free access to the electricity market.
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 site. The recommendation follows the figures from the analysis.
