New online map shows Germany’s renewable energy feed-in capacity across distribution grids

Fifty-three photovoltaic systems with a combined capacity of 638 kW feed into the distribution grid operated by Max Peissker in Kaulsdorf, Thuringia, while 575,136 PV systems with a combined capacity of around 13.5 GW feed into the Bayernwerk Netz grid. The figures come from a new, freely accessible online map published by the evu+ initiative, part of the Edna Federal Association for Energy Market & Communication.

Updated every six months, the map shows the number and capacity of generation plants and storage systems connected to the distribution grids of Germany’s 871 grid operators. Battery storage systems are also included. Users can analyze the data by grid operator, federal state, generation technology and other criteria. The map does not, however, show available grid capacity.

Martin Käßler, who works in communications and marketing at edna member Fraunhofer IOSB-AST in Ilmenau, created the map with AI assistance, using data from the Core Energy Market Data Register (Marktstammdatenregister).

In July, the Federal Network Agency (Bundesnetzagentur) published a map showing supply quality across Germany’s distribution grids. It uses different colors to indicate how quickly and comprehensively grid operators are implementing the energy transition and the extent to which they are using digital solutions.

“The frequently voiced criticism that Germany has too many grid operators misses the mark,” said Richard Plum, managing director of the edna Federal Association for Energy Market & Communication. “Our new map impressively demonstrates that small and medium-sized grid operators, in particular, make an indispensable contribution to electricity supply and security of supply.”

According to Plum, these operators are also key drivers of the energy transition, as electricity generation within their grids relies almost entirely on renewable energy sources.

The association rejects criticism that Germany’s distribution grid landscape is too fragmented. It points to other European countries for comparison. Denmark has around 55 distribution grid operators and Finland 75, giving both countries a grid operator density relative to population size similar to Germany’s.

Germany has around 98,000 inhabitants per distribution grid operator. By comparison, Austria has around 75,000 inhabitants per operator, with 120 distribution grid operators in total, while Switzerland has around 15,000 inhabitants per operator and approximately 600 operators.

The Edna Bundesverband Energiemarkt & Kommunikation e.V. focuses on market communication processes, digitalization and IT standardization in the energy sector. Its members include municipal utilities, grid operators and energy suppliers, as well as software manufacturers and IT service providers serving the energy industry.
