The new energy centre at the Gropper private dairy is characterised by an AI-based control system, which includes, amongst other things, a water treatment plant and two battery storage systems. Across an area of 16 hectares, 27,552 PV modules generate around 19 million kWh of solar power per year. Gropper Dairy, based in Bissingen, Germany, is the sole consumer of the electricity produced at the solar park. The electricity generated is used to power an electric boiler for steam production, as well as to reduce the output of the gas-fired combined heat and power (CHP) units. These measures alone result in annual CO₂ savings of 4,000 tonnes. To further increase these savings, a battery storage system is also in use. This further improves the ‘output’ of the PV park, thereby increasing the CO₂ savings to a total of 5,000 tonnes per year.
