On 28 June 2024, the transmission system operators (TSOs) submitted their draft of the Scenario Framework for the Network Development Plan (NDP) 2037/2045 (2025) to the Federal Network Agency (BNetzA). The agency launched the draft for public consultation in September 2024 and approved it on 30 April 2025.
Based on the scenario framework approved by the BNetzA, the TSOs have prepared the first draft of the NDP 2037/2045 (2025) and published it on 10 December 2025. The following consultation ended on 14 January 2026. After evaluating all received comments, the TSOs prepared the second draft of the NDP 2037/2045 (2025), submitted it to the BNetzA on 13 March 2026, and published it on this website on 16 March 2026.
With the publication of the first draft of the NDP 2037/2045 (2025), the TSOs agreed to present the projects and measures in the new digital project library. All project fact sheets are also available collectively as a PDF in “The NDP for Download” section further down this page.
Scenario Framework for NDP 2037/2045 (2025)
With the draft Scenario Framework for the NDP 2037/2045 (2025), the TSOs have for the second time developed a database that takes into account different technical solutions and different speeds on the path to greenhouse gas neutrality. In this draft, the TSOs again present three scenarios for each of the years 2037 and 2045. These scenarios depict the range of probable developments for the future electricity supply in Germany and Europe.
The resulting Scenario Framework to be approved by the BNetzA forms the basis for planning the grid expansion in the next NDP. Compared to the previous Scenario Framework, there have been a number of further developments: The amendment to the Energy Industry Act harmonises the process flow in the network development plans for electricity, gas and hydrogen. For the first time, this provides the opportunity to synchronise the respective scenarios in line with sector coupling. The framework for this is provided by the system development strategy of the Federal Ministry for Economic Affairs and Climate Action.

NDP 2037/2045 (2025)
1st draft
For the first time, a significantly broader scenario corridor serves as the basis for network development planning. The NDP maintains a clear focus on the climate-neutral power grid for 2045 and presents the two scenario paths A and B for the target years 2037 and 2045.
The results for scenario path C will be published with the second draft, together with a 2032 trend scenario. An additional scenario A 2037+, featuring a higher onshore wind capacity, will be published in 2026 as a special report to the NDP.
Scenario path A assumes a lower and more gradually increasing electricity demand. The expansion of photovoltaics and onshore and offshore wind is more moderate than in scenario path B, which is aligned with energy and climate policy targets. At the same time, the importance of large-scale battery storage increases significantly across all scenarios.
Some grid expansion measures confirmed in the previous NDP prove their robustness in the NDP 2037/2045 (2025) particularly in the long-term horizon of 2045, enabling a more gradual and time-staggered implementation of the required network expansion.
For the first time, offshore optimisations are applied: the focus lies on actual energy yield. Adjusted area layouts, better utilisation of grid connections and strengthened European interconnection allow for a reduction in the required offshore grid connection systems.
Market shortages in technical components and services have led to significant cost increases compared to previous assumptions. The new NDP therefore places greater emphasis on achieving an optimal balance between investment costs, remaining requirements for congestion management and overall grid security – a key lever for improving economic efficiency.

NDP 2037/2045 (2025)
2nd draft
The consultation on the first draft of the NDP 2037/2045 (2025) ran from 10 December 2025 to 14 January 2026 and provided an opportunity for stakeholders to submit comments. A total of 990 submissions were received, corresponding to 232 substantively different comments. The “co-signing” function was also used 700 times.
Of the 990 submissions, 208 were from private individuals, representing the majority of contributions, as in previous consultations. The second largest group was made up of 92 submissions from municipalities and public authorities. Further contributions were received in particular from associations in the fields of agriculture, environmental and consumer protection, small and medium-sized enterprises, and industry, with 21 submissions.
Many of the comments addressed topics such as the wider scenario range, recent developments and future perspectives for electricity consumption, the role of battery storage, flexible loads and electrolysers, the required offshore network expansion, the implementation of high-voltage direct current (HVDC) transmission as overhead lines or underground cables, and coordination between transmission and distribution system operators. Comments for which consent to publication was given can be viewed in detail here. Following a content review of the submitted comments, the TSOs revised the first draft based on the received contributions and updated technical framework conditions.
In addition to Scenarios A and B, the second draft also includes Scenario C for the target years 2037 and 2045.
The results of Scenario C provide an expanded view of potential grid expansion needs up to 2037 and 2045. Compared with Scenarios A and B, Scenario C assumes higher electricity consumption and greater renewable generation capacities. The Scenario C 2045 also includes two new HVDC connections.
