TSOs launch grid plan consultation
First draft of the Grid Development Plan Electricity 2037/2045 sets out paths to a climate-neutral grid and highlights major savings potential.

Germany: Germany’s transmission system operators (TSOs) Amprion, 50Hertz, TenneT Germany and TransnetBW have released the first draft of the Grid Development Plan (GDP) Electricity 2037/2045 (2025). With this step, they open a public consultation, allowing feedback online or by email until 14 January 2026. All comments will be considered in the second draft, which will then be submitted to the Federal Network Agency (BNetzA).
The new plan is based on a broader scenario framework confirmed by BNetzA in April. It reflects recent technological progress, energy market trends and changing conditions. For the second time, the GDP focuses on building a climate-neutral electricity grid by 2045.
The first draft outlines two scenario pathways, A and B, for the target years 2037 and 2045. Pathway A is seen by the TSOs as a stable and reliable basis for planning. It assumes lower and more slowly growing electricity demand and a more moderate expansion of solar and wind power than pathway B, which follows energy and climate policy targets. In all scenarios, large-scale battery storage plays a much bigger role.
A key theme is economic efficiency. Some grid expansion measures planned earlier show their full value mainly by 2045, allowing projects to be spread over time. The draft also points to a reduced need for certain high-voltage direct current connections, while confirming others as essential.
For the first time, offshore optimisation focuses on actual energy output rather than installed capacity. This could cut several offshore grid connections and significantly lower costs.
Overall investment up to 2045 is estimated at $423–458 B (€360–390 B), with optimisations in scenario A delivering savings of almost $94 B (€80 B).
