Schleswig-Holstein Netz (SH Netz) is the regional electricity and gas network operator in the German state of Schleswig-Holstein and parts of northern Lower Saxony. As part of the HanseWerk Group and the wider E.ON group, the company operates high-, medium- and low-voltage electricity networks and gas pipelines across more than 900–1,000 municipalities, supplying around 2.8 million directly or indirectly connected customers. Its infrastructure includes about 51,000 kilometres of electricity networks, 13,500 kilometres of gas networks and 7,500 kilometres of communications networks, which are monitored from a central network control centre in Rendsburg. SH Netz also manages public and private grid connections, metering, and network usage for residential, commercial and industrial customers, and provides technical services around substations and transformer stations from planning and construction through to maintenance and operational management.
The company positions itself as a key partner in the German energy transition. It has connected around 35,500–36,000 renewable energy plants, including tens of thousands of wind turbines and solar installations, to its distribution grids and supports feed-in management, Redispatch 2.0 processes and a range of distributed generation technologies. SH Netz has invested in innovative projects such as the first plant in Schleswig-Holstein to feed green hydrogen into the natural gas grid at Brunsbüttel, developed with Wind2Gas Energy and located on the Covestro industrial site, and operates electric-vehicle charging infrastructure including 22 kW AC public charging points. It collaborates with technology and service partners on grid reliability and digitalisation, including universal high-voltage cable repair solutions, GIS and business intelligence systems, and digitised mail handling, while expanding the 110 kV distribution grid and engaging municipalities and stakeholders to support acceptance of grid expansion. Municipal participation is a core feature of its ownership model, with hundreds of municipalities holding shares and influencing network development.
