Rolls-Royce and the project development company, Abo Wind, commissioned a large-scale mtu battery storage system at a solar farm in Bavaria in Germany earlier this year. The plant can produce a total of 10 000 megawatt-hours (MWh) of green electricity per year, equivalent to the demand of around 3 000 three-person households and the avoidance of around 6 300 tonnes of CO2.
Combining solar PV energy and mtu battery storage enables maximum use of renewable energy and grid stabilisation.
The two companies are also working together on three other projects of this type and already established in the German states of Rhineland-Palatinate and Hesse.
Andreas Görtz, President Sustainable Power Solutions at Rolls-Royce Power Systems, said: “Working in partnership with Abo Wind we can serve the energy market of the future effectively.”
All plants are subsidised on the basis of the German government's innovation tenders due to the sustainable and innovative solution they provide. They serve to stabilise the power grid and enable maximum use of renewable energies. The batteries charge electricity from the photovoltaic system when needed – for example, in times of high production of solar power with low demand – and release it again at a later time. In this way, more electricity from renewable sources can be integrated into the power grid.
Thomas Treiling, Head of Project Development Wind and Solar at Abo Wind said: “The only way we can increase the share of renewables in generated electricity and achieve the climate targets is with sufficient storage capacities. We are proud to be among the pioneers in Germany with these hybrid projects and to have a reliable partner at our side in Rolls-Royce.”
For the latest Abo Wind solar farm in Bavaria, the Power Systems business unit of Rolls-Royce has supplied an mtu EnergyPack QG large-scale battery storage system with a capacity of 5.8 MWh and an output of 2.9 MW. With its modular design and high energy density, the large-scale storage solution can be adapted flexibly to project-specific outputs and capacities.
For the three other plants on which the companies have collaborated, in Rhineland-Palatinate and in Hesse, Rolls-Royce supplied a total of three battery containers (twice 1.5 MW output and 2.13 MWh storage capacity, once 550 kW output and 0.71 MWh storage capacity).
