The four German power transmission system operators (TSOs) recently published draft development plans announcing total estimated investments of $38-41 billion (€34-36 billion).

The investment plans go through 2030 and 2035 and assume that the DC-1, DC-3 and DC-5 HVDC transmission lines are built, including $6.7 billion for the startup of the network, reports Enerdata.

According to the draft plan, German TSOs intend to build 3,800 km of new lines, including around 2,600 km of HVDC lines and around 1,200 km of AC lines. They also plan to reinforce between 7,600 km and 8,500 km of existing cables.

Around 330 km of cross-border connections to Belgium, Denmark, Norway and Sweden should be built, with a total transmission capacity of 8 GW.

Nearly 2,800 km of offshore lines could be developed by 2030 (3,700 km by 2035), with a planned network capacity ranging from 7.4 GW in 2030 to 11.4 GW in 2035. In that case, total investments would near $18 billion by 2030 and $28 billion by 2035.
