Main Information

In order to better integrate renewables into the grid, EnBW developed a dynamic tariff that allowed for flexibility in the participating customers’ consumption behaviour. Customers were provided with traffic light-based dynamic price signals, whose order changed on a daily basis. While a green signal stood for the availability of electricity at a low price, a red light signalled that electricity generation was low and was therefore, more expensive. The households had the possibility to control their energy consumption and energy data via different technological devices (computer, mobile).

The smart meter continuously relayed the consumption data of the pilot customers directly to EnBW‘s central billing system. The billing system then sent energy consumption evaluations via the Internet to the MeRegio cockpit found on each participant’s PC.

An evaluation of the project showed that consumption flexibility of up to 25 per cent and an average value of 10 per cent could be achieved.

The practice has also been selected by the German Federal Ministry for Economic Affairs and Energy’s “E-Energy – Smart Energy Made in Germany” subsidies program.

Additional Information

EnBW (Energie Baden-Württemberg AG) is ranked among the largest energy supply companies in Germany and in Europe. With a workforce of around 20,000 employees, EnBW supplies electricity, gas, water and energy-related products and services to 5.5 million customers

A smart grid is an electricity network based on digital technology that is used to supply electricity to consumers combined with bidirectional digital communication. This system allows for monitoring, analysis, control and communication within the supply chain to help improve efficiency, reduce energy consumption and cost, and maximize the transparency and reliability of the energy supply chain
