German Grid Operators Update Connection Rules for Large Electricity Consumers
Four German transmission system operators are revising connection rules for new large electricity consumers. Future applications will be evaluated based on higher project feasibility and benefits to the grid. The changes come amid increased competition for grid access driven by data centers, heat pumps, and EV charging infrastructure. The process for new connections typically takes up to seven years. Operators will assess applications collectively, using measurable criteria, to prevent overload and ensure fair access.

Four German transmission system operators, Amprion, TenneT, Transnet BW, and 50 Hertz, will change rules for connecting new large electricity consumers due to increased competition for grid access. Future applications will be evaluated based on project feasibility and benefits to the grid.
The current 'first come, first served' system has led to an overwhelming number of requests exceeding available connection capacities. Applications will be assessed regularly using transparent criteria, including project permits and technical concepts.
Similar systems are in place in the UK and Norway. Additionally, concerns arise from large battery storage projects, with over 250 GW of connection requests recorded last November. Operators are advocating for legislative changes to avoid detrimental lock-in effects. A similar situation is emerging in the Czech Republic.
