EnBW subsidiary Netze BW GmbH and eight partners from research and industry started the "grid control" project funded by the Federal Ministry of Economics in Freiamt, Baden-Württemberg (district of Emmendingen in the Black Forest region) in a ceremony on 11th October 2017.

"grid control" provides a total solution for future power distribution grids. It is the first nationwide project with a holistic approach to take all areas of the value chain from generation to end consumer into account, and combines the topics of Smart Grid, Smart Home and Smart Market. Flexibilities such as consumers and generation plants are used to prevent bottlenecks, and can participate in the electricity market at the same time. The PV systems of around 30 households and agricultural businesses were equipped with new control and measurement technology, and additional battery storage systems and energy management systems were installed. As well as several ADS-TEC home and business storage solutions with 9 or 19 kWh, the PowerBooster is an important component with a central task as an outdoor battery solution with a capacity of 120 kWh or output of 120 kW. Other test components are a controllable local mains transformer and a charging station.

"We need new, intelligent technologies in order to be able to guarantee a long-term safe, environmentally-friendly and cost-effective power supply." stated Director General Helmfried Meinel from the Baden-Württemberg Ministry of the Environment, Climate Protection and the Energy Sector at the ceremonial event at the start of the field testing.

Future electromobility also has a significant influence. The coordination of all producers and consumers in an "intelligent" grid is therefore important: "The government's goal of having a million electric vehicles on the roads by 2020 is another challenge for the network." explained Martin Konermann, CEO of Netze BW, citing a residential area in which all commuters would like to recharge their cars at the same time in the evening as an example. This could take the distribution grids to their load limit and requires expensive network expansion, said Konermann.
