Siemens Energy seals framework agreement to strengthen Norwegian power grid

June 14, 2021

  • Framework agreement for construction and upgrade of substations in Southern Norway
  • Norway is a front-runner in phasing out climate-harming gases in power transmission
  • Siemens Energy’s vacuum interrupter technology in combination with clean air insulation reaches almost 6-million hours of commercial operation


Siemens Energy and Norwegian distribution system operator Lyse Elnett signed a framework agreement to strengthen the Norwegian power grid. Under this agreement, Siemens Energy will provide services and transmission products for various substations in the Sør-Rogaland region in Southern Norway. By constructing new substations and modernizing existing ones, Lyse Elnett not only rises to the challenges of increasing energy demand and the volatile feed-in of renewables: the framework agreement also stipulates that Lyse Elnett can, over time, fulfill its objective of more environmentally friendly power transmission by eliminating fluorinated gases (F-gases) in their substations. 

“Limiting the environmental impact of our operations without compromising on safety and reliability of power transmission, is a top priority for us. When it comes to reducing the usage of Fgases, we know that the alternatives from Siemens Energy have zero global warming potential. The agreement is an essential step on our pathway to a more environmentally friendly operation of our substations,” says Evy Thorbjørnsen, project director at Lyse Elnett.

Norway is one of the global front-runners in phasing out climate-harming F-gases in the power grid. In the past two years, Siemens Energy has received orders for more than 60 bays of F-gas-free gas insulated switchgear (GIS) up to 145 kilovolts from Norwegian grid operators. The centerpiece of the switchgear is the combination of clean air and the game changing technology of vacuum interrupter. In medium voltage applications, for decades the vacuum interrupter units, which are sealed for life, have shown the outstanding performance. Since 2010 Siemens Energy’s vacuum interrupter technology is available for high-voltage switching applications and have reached almost 6-million hours of commercial operation, demonstrating the outstanding performance capabilities.

“Driven by the same goal to transmit power efficiently at the highest levels of safety, while also helping to reduce the ecological impact of power transmission, our state-of-the-art transmission technologies will accompany Lyse Elnett on their pathway towards decarbonization,” says Beatrix Natter, Executive Vice President Transmission at Siemens Energy. “Redesigning switching technologies in substations and avoiding F-gases is key to make the transmission grid more sustainable.”

Provided that the total agreement’s scope of supply for the maximum runtime of eight years are called up, the agreement has a total volume of estimated 200 million Euros. The agreement covers design and construction of new substations as well as modifications and upgrades of existing substations, including the supply of transmission products and services. The largest and most important assignments will be the delivery of 145 kV GIS with associated protection and control systems.

Siemens Energy is one of the world’s leading energy technology companies. The company works with its customers and partners on energy systems for the future, thus supporting the transition to a more sustainable world. With its portfolio of products, solutions and services, Siemens Energy covers almost the entire energy value chain – from power generation and transmission to storage. The portfolio includes conventional and renewable energy technology, such as gas and steam turbines, hybrid power plants operated with hydrogen, and power generators and transformers. More than 50 percent of the portfolio has already been decarbonized. A majority stake in the listed company Siemens Gamesa Renewable Energy (SGRE) makes Siemens Energy a global market leader for renewable energies. An estimated one-sixth of the electricity generated worldwide is based on technologies from Siemens Energy. Siemens Energy employs more than 90,000 people worldwide in more than 90 countries and generated revenue of around €27.5 billion in fiscal year 2020.
