Battery Storage
Turn your battery into a source of income
Battery accumulators are taking on important tasks in industry and trade: For example, they replace internal combustion engines as a drive source or absorb peak loads in order to reduce electricity procurement costs. But with the help of batteries you can not only save, but also earn money: By providing control energy for the power grid, you can generate additional income - without significant effort or investment costs.
Reserve Power from Batteries
Your battery can help stabilize the power grid
Fluctuations in the electricity grid are increasing due to the variable feed-in of renewable energy sources such as wind and sun. In order to keep the network stable despite these conditions, the network operators need capacities available at short notice, the so-called balancing power. Through our virtual power plant, your battery storage can offer this standard output if it has at least 150 kW. Just the part of your storage that you have reserved for your FCR delivery is affected during the provision period – the primary functions of your battery will not be affected.
Smart secondary use: By giving your battery storage an additional purpose, it supports the energy transition and generates attractive revenues.
Service-oriented: We take care of the connection of your battery storage to the virtual power plant and carry out the test procedure for the balancing energy market, the prequalification, for you.
Great know-how: As a long-standing provider of balancing energy in various countries in Europe, we trade the reserve capacities of your battery as primary reserve power (FCR/R1), a particularly lucrative form of balancing energy.
No functional impairment: Together with you, we determine which time windows are suitable for the provision of control power. The primary function of your battery storage (e.g. peak shaving) always takes precedence, of course.

Taylor-made for batteries: Primary reserve capacity is the first to be activated to prevent a power outage and is the most attractive type of control reserve to sell. In the event of fluctuations in the power grid, power is temporarily stored in your battery or called up from it. For this you will receive a performance price as revenue.

We make more of your battery
As one of Europe's largest virtual power plants, we already connect more than 5000 decentralized power generators and consumers. This alliance enables us to enable smaller units such as wind, solar and biogas plants as well as battery storage facilities to participate in lucrative electricity markets. Via our own trading floor, we trade on various European power exchanges and provide reserve capacities for grid stabilisation. In this way, we are helping to shape the energy landscape of the future - for a power supply from 100% renewable energies.
