Nortorf-Steinburg: Larger substation for more green electricity!
SH Netz is expanding the Nortorf-Steinburg substation for 3.5 million euros in order to better feed in renewable energy by spring 2026.

Nortorf-Steinburg: Larger substation for more green electricity!
There is currently a lot of investment in the future of energy in the Steinburg district: This Nortorf-Steinburg substation is being expanded to meet the increasing demand for electricity from renewable energies. With an impressive investment sum of around 3.5 million euros, the new infrastructure is intended to significantly increase the amount of green electricity fed into the grid.
Construction work has already begun and will last over a year. The heart of the project is a new large-scale transformer with an output of 63 megavolt amperes (MVA), which is...Spring 2026should go into operation. In order to cope with the special soil conditions of the Wilstermarsch, over 300 piles were inserted up to 30 meters deep into the ground. This measure is particularly important in order to safely store the transformer, which weighs around 80 tons, and is transported from Zagreb in Croatia to Nortorf over a distance of more than 1,300 kilometers.
Environmental protection and climate goals
A clear advantage of this expansion is the long-term security of the district's supply of renewable energy. According to that Federal Ministry of Economics Renewable energies make a significant contribution to achieving climate protection goals in Germany. The share of renewable energies in final energy consumption for heating and cooling rose to 18.1% in 2024, with the use of electricity in the transport sector also becoming more important.
Overall, renewable energies could avoid around 256 million tons of greenhouse gas emissions in 2024. These figures make it clear that promoting green electricity is not only a locally important goal, but also a globally important goal.
A look into the future
SH Netz will operate three transformers with 63 MVA each in the new substation, with a fourth being planned. The medium-voltage system for the connection is also already installed ready for operation, which ensures that future feed-in runs smoothly. Technical monitoring and control is carried out by SH Netz's central network control center, which is active 365 days a year. This will sustainably strengthen security of supply in the region.
At a time when the demand for renewable energies is constantly increasing, this project represents good business for the future of energy supply in Germany and sends a clear signal for increasing environmental protection. SH network shows that you have a good hand when it comes to mastering the challenges of the energy transition.
