Uniper SE and TenneT BV have agreed to develop a brand new central community node in Großkrotzenburg, Germany to serve knowledge center-driven progress in energy demand within the higher Frankfurt space, focusing on to begin operation sooner than deliberate.
Underneath the partnership, German energy and gasoline utility Uniper agreed to promote a part of a plot of land on the Staudinger energy plant to allow TenneT, a transmission system operator within the Netherlands and Germany, to construct a switching station.
“The core of the mission is the development of a brand new 380-kilovolt switchyard, which is able to create intensive extra capability for urgently wanted buyer connections within the Rhine-Foremost space”, mentioned a joint assertion on-line. “The connection of recent and current extra-high-voltage strains will additional strengthen electrical energy transmission to the Frankfurt metropolitan space and neighboring areas, notably Decrease Franconia.

“On the similar time, the brand new grid infrastructure will kind the idea for connecting essential Uniper transformation initiatives on the Staudinger website. Plans embrace a hydrogen-ready mixed cycle gasoline turbine plant as a part of the German authorities’s anticipated tender for versatile technology capacities, in addition to the possible institution of battery storage amenities and knowledge facilities”.
The station is scheduled to begin service by 2030, Uniper mentioned.
“With this mission, we’re launching our intensive grid growth program within the Rhine-Foremost area, one in all Germany’s key progress areas”, mentioned TenneT Germany chief working officer Ina Kamps.
In September 2025 Tennet mentioned it had submitted a plan to authorities and thereby launched the approval course of for a 380 kV extra-high-voltage overhead line stretching about 9 kilometers (5.59 miles) between Bommersheim and Eschborn. The brand new line would exchange a piece of the 380-kV line between the Frankfurt Südwest and Karben substations.
“It is a first, essential step in the direction of a demand-oriented and sustainable electrical energy grid within the area”, TenneT mentioned in a press launch.
The mission is designed to extend transmission capability by over 50 % by means of an upgraded infrastructure, with plans for integration into the pipeline community.
Additionally final yr TenneT and its companions commissioned a phase-shifting transformer on the Frankfurt Nord substation to allow the focused management of electrical energy flows, which TenneT mentioned was “a decisive step towards making Frankfurt’s energy grid future-proof and environment friendly for the rising necessities of a climate-friendly energy provide”.
Early in 2026 TenneT introduced plans to construct one other extra-high-voltage line between the Frankfurt Griesheim substation and Schwanheim. It plans to launch survey work by yearend.
