Modernizing a 380-kilovolt power substation in Bavaria, with SPIE being the facilitator for the replacement of the Jura line.
In a significant move towards strengthening Germany's energy infrastructure, SPIE Germany Switzerland Austria, a business unit of the SPIE Group, has begun work on the expansion of the Sittling substation. This project forms part of the larger Juraleitung replacement construction, aimed at increasing the voltage from 220 to 380 kilovolts and boosting the network's capacity for renewable energy transport.
The Sittling substation expansion, SPIE's largest project in Bavaria to date with TenneT, involves comprehensive services, including 3D-supported planning, delivery, and assembly of steel elements, control cables, and high-voltage equipment. The project requires substantial material resources, with approximately 900 tonnes of steel, 150 tonnes of copper, and up to 200 tonnes of aluminium set to be utilised.
The Juraleitung power line, a 170-kilometer-long transmission line connecting Raitersaich and Landshut, ensures the supply of electricity, including from renewable sources, from Middle Franconia to Lower Bavaria. The aim of the Juraleitung's replacement is to strengthen the network for the transport of renewable energies and drive the energy transition.
Christoph Pichlmeier, Sales Manager Substations Region Southeast at SPIE Germany Switzerland Austria, emphasises the importance of an established team for efficient capacity and logistics planning. SPIE is not only responsible for the technical equipment of the expansion of the Sittling substation but also for the technical equipment of the replacement construction of the Raitersaich substation, scheduled to go into operation in 2026.
The project's safety standards are of utmost importance, with SPIE demonstrating high standards in workplace safety, including a HSE Safety Plan, Safety Culture Ladder certification at level 4, and various technical concepts and protective measures.
The expansion of the Sittling substation is just one of the five substations along the Juraleitung that SPIE is involved in. The SPIE Group, the independent European market leader for multi-technical services in the energy and communication sectors, is committed to contributing to Germany's energy transition and the sustainable development of its infrastructure.
[1] The commissioning of the Juraleitung project will take place in five phases by the end of 2030, while the network remains in operation.
- The Sittling substation expansion, a significant endeavor in the manufacturing industry, requires substantial investments in finance, particularly in the purchase of around 900 tonnes of steel, 150 tonnes of copper, and up to 200 tonnes of aluminium.
- The energy sector is set to witness a transformation with the Juraleitung replacement construction, an initiative in the technology domain, as it aims to increase the voltage from 220 to 380 kilovolts and boost the network's capacity for renewable energy transport.
- The business of providing technical equipment for the expansion and replacement of substations along the Juraleitung, such as the Sittling substation and the Raitersaich substation, falls under the portfolio of the SPIE Group, a pioneer in the energy and communication sectors of the industry.
