TSOs 50Hertz, Amprion, TenneT and TransnetBW have published the first draft network development plan (NEP) 2035 (2021) for the German grid.
The move will start with a four-week public consultation, which will be open online, by e-mail or in writing until 28 February 2021.
The NEP 2035 (2021) looks at the network development needs in order to continue to supply Germany reliably and efficiently with electricity at 2035 and 2040 in three scenarios.
In terms of gross electricity consumption, the share of renewable energy is between 70 and 74% in 2035 and 76% in 2040.
These assumptions assume an installed renewable energy capacity between 233GW and 261GW in 2035 and 268GW in 2040.
The NEP 2035 (2021) documents that wind energy is the central renewable energy source of the energy transition, especially the power generation in the North Sea and Baltic Sea is becoming considerably more important.
In all scenarios of this NEP, wind energy accounts for the largest share of the energy mix.
However, photovoltaics are expected to see a sharp increase in installed power and thus generation.
Feedback will be incorporated into the second draft of the NEP, which is then handed over to the Federal Network Agency (BNetzA) for examination.
The draft takes into account an energy system without nuclear power and largely without coal-fired electricity within the German and European energy and climate policy guidelines.
The estimated investment volume for the proposed measures on land is between €72bn and €76.5bn.
This sum already includes the investments for the so-called “start-up network”.
It also incorporates measures for which a planning approval procedure has already been opened or is about to be opened, which are already planned or under construction.
The NEP and the Land Development Plan (FEP) together form the basis on which the offshore network for the North Sea and Baltic Sea is developed.
Based on the scenario framework approved by BNetzA and the areas identified in the 2020 FEP, the nEP 2035 (2021) offshore network for the integration of 28 to 32GW of offshore wind energy will result in investments of between €33bn and €38.5bn.
The extension network share of the offshore network in 2035 will be between 3210 and 3860km.
