- Electrical fitting in substation and cable transition systems
- Strong grid infrastructure in preparation for the expansion of renewable energies
- Focus on experience and delivery of highest quality
The East Coast Line is one of the key projects in the field of grid infrastructure in Schleswig-Holstein. It strengthens Germany’s extra-high voltage grid, increases transmission capacity for wind energy, and guarantees grid stability. The approximately 115-kilometre extra-high voltage line runs from Ulzburg (north of Hamburg) via Lübeck to Göhl (southwest of Fehmarn) and is expected to be commissioned in 2027.
Innovative technology that generates connections
On behalf of network operator TenneT, the Substations/HV Germany East profit center of EQOS Energie performs the electrical fitting for central components of the line in the Ulzburg substation, the starting point of the East Coast Line, as well as in three cable transition systems in Henstedt-Ulzburg and Kisdorferwohld. The latter ensure a safe transition from the overhead line above ground to the underground cables and vice versa from the underground cables to the overhead lines. As a result, EQOS Energie is one of the partners in an extremely innovative project, because the East Coast Line involves pioneering technological work.
“The East Coast Line is of fundamental importance for a future-ready grid infrastructure for the transmission of renewable energy over long distances. The fact that EQOS Energie is perceived positively in its self-image as a green energy enabler and has already been involved in the construction of overhead lines for subprojects of the East Coast Line in the past, such as the new construction of high and extra-high voltage lines, is an endorsement of our outstanding performance,” said Uwe Trampnau, the EQOS Energie managing director in charge.
Electrical fitting and quality orientation at the highest level
The EQOS Energie teams, each with a construction manager and up to 10 fitters, perform the entire electrical installation for the systems, which is very extensive. In addition to the construction of the 380-kV cable transition systems, this also includes construction of a 380-kV switchgear with 19 bays. Wladimir Haak, head of the Substations/HV Germany East profit center: “With all of these challenges, our experience, expertise and focus on quality specifically come into play.”
