Battery storageThe 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.
