Mode of operation
Substations collect electrical energy from generators and transmit it to the national grid. They also increase / decrease the voltage with the help of transformers.
Benefits of the ENERTRAG Verbundkraftwerk
- Collection of electrical energy
- Connection point to the electricity grid
- Transforming / regulating between different voltage levels
Special feature at ENERTRAG
The Bertikow substation uses a self-developed EZA controller for power control, which enables the efficient control of mixed parks and EEG systems and contributes to the stability of the power grid. The substation is coupled with a large battery storage system, an electrolyzer and an H₂ reconversion plant to create a central power hub. From here, hydrogen is fed directly into the passing EUGAL pipeline.

How it works
Electrolyzers split water into hydrogen and oxygen using an electric current. The gas produced can be easily stored and transported.
Benefits of the ENERTRAG Verbundkraftwerk
- Storage of renewable energy in coupled hydrogen storage possible
- Increasing flexibility and grid stability by drawing surplus electricity from wind and PV systems
- Stabilization of the power grid through hydrogen reconversion
Besonderheit bei ENERTRAG
ENERTRAG only produces green hydrogen, as the electrolyzer is powered by renewable energy.
WIND-HEAT-STORAGE
Wind-heat storage NechlinTechnical data
Nominal output | 2.000 KW |
Annual production | 780 MWh |
Commissioning | 2020 |
Households | 35 |
How it works
The wind heat storage system converts electrical energy into thermal energy by heating water using a heating rod. The hot water can be stored and supply consumers with heat when required.
Benefits of the ENERTRAG Verbundkraftwerk
- Storage of surplus wind energy
- Provision of clean thermal energy
- Coupling of thermal and electrical energy (power-to-heat)
Special feature at ENERTRAG
The Nechlin wind heat storage facility is partly operated with surplus electricity from wind turbines so that they do not have to be curtailed.
BATTERY STORAGE
Battery storage CremzowTechnical data
Nominal power | 22 MW |
Storage capacity | 34,8 MWh |
Commissioning | 2019 |
Investment volume | 17 million euros |
How it works
A battery stores energy from generating plants by converting it into chemical energy and then converting it back again when required.
Benefits of the ENERTRAG Verbundkraftwerk
- Batteries compensate for fluctuations in the electricity grid and provide additional power
- Provision of system services such as black start and balancing energy
- Peak load coverage
Special feature at ENERTRAG
The ENERTRAG Cremzow battery storage system is black-start capable and can restore the grid in the event of a power failure.

How it works
Incident sunlight is used to generate electrical energy in solar cells.
Benefits of the ENERTRAG Verbundkraftwerk
- Consistent generation of clean electrical energy during the day
- Can be stored in combination with battery and hydrogen production
Special feature of ENERTRAG
Thanks to the large number of wind power and photovoltaic systems in the ENERTRAG Verbundkraftwerk, the different and fluctuating generation patterns balance each other out. This ensures continuous power generation.
WINDPOWER

Maximum wind speed | 25 m/s |
Mode of operation
Wind turbines utilize the force of the wind to drive rotor blades and, via these, a generator. This generates electrical energy.
Benefits of the ENERTRAG Verbundkraftwerk
- Sustainable generation of large quantities of electrical energy
- Production possible day and night
- Can be stored in combination with battery and hydrogen production
The energy system in detail
By hybridizing wind and solar energy and converting renewable energy into storable energy sources, the ENERTRAG combined power plant in Uckermark is able to supply renewable energy predictably and in line with demand and stabilize the electricity grid.
Primary energy
The ENERTRAG Verbundkraftwerk® in Uckermark generates large quantities of sustainable primary energy from wind and sun, day and night. The wind fields and the Kreuz Uckermark photovoltaic plant are connected to each other by their own lines and transformer stations.
Collection and network infrastructure
The electricity is collected in a hybrid manner in local networks, forwarded via substations within the compound power plant area to the central substation and there primarily fed into the transmission network. Hydrogen pipelines and heat pipes can also be part of the local integrated power plant network infrastructure.
Storage
Surplus energy is stored, for example in the Cremzow battery storage facility, with the help of an electrolyzer in Wittenhof as green hydrogen or in the Nechlin wind heat storage facility.
The Cremzow battery storage facility is black-start capable and can restore the grid in the event of a power failure.
Conversion
The electrolyzer uses electricity to split water into green hydrogen and oxygen. If required, electricity can be drawn from hydrogen or the battery storage system to stabilize the power grid by reconverting it into electricity. The wind heat storage system converts electrical energy into clean thermal energy using power-to-heat.
Utilisation
The electrical energy generated is bundled via a collection substation. For transmission to the public power supply, the central Bertikow substation connects the ENERTRAG Verbundkraftwerk® in Uckermark with the national transmission grid at a single transfer point. In the future, hydrogen will be fed into the passing EUGAL pipeline. A self-developed control system ensures a continuously adjustable energy flow from the generation plants into the electricity and gas grid.
Households and industry will utilize the electricity provided on demand, as well as heat from the local heat extraction of surplus electricity. The hydrogen will be fed into the existing natural gas network and the future hydrogen network or converted into hydrogen derivatives, for example ammonia, methanol or paraffin.
Control technology and control system
The ENERTRAG control center in Dauerthal uses the Powersystem software to continuously monitor and control the operation of the entire ENERTRAG Verbundkraftwerk® and its components, including energy generation, conversion, distribution and grid connection.
ENERTRAG generates renewable energy sustainably so that the earth remains liveable.
ENERTRAG brings people, nature and the energy transition forward. The goal: zero emissions, everywhere in the world.
