Norway, Sandnes: Norwegian distribution system operator Lyse Elnett and Siemens Energy 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 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, but the framework agreement also stipulates that Lyse Elnett can, over time, fulfil its objective of more environmentally friendly power transmission by eliminating fluorinated gases in its 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 use of F-gases, 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,” said Evy Thorbjørnsen, project director at Lyse Elnett.
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 kV from Norwegian grid operators. The centrepiece of the switchgear is a combination of clean air and vacuum interrupter technology. Since 2010, Siemens Energy’s vacuum interrupter technology is available for high-voltage switching applications and has reached almost six million hours of commercial operation.
Provided that the total agreement’s scope of supply for a maximum runtime of eight years is called up, the agreement has a total volume of an estimated $242.4 M. The largest and most important assignments will be the delivery of 145-kV GIS with associated protection and control systems.
