Gas-insulated substation LIFE Blue GIS

for high-voltage transformers

Besides significant savings of greenhouse gases through being emission-free, any PFAS input is avoided – which is not the case with other alternatives to SF6. In addition, the project will deliver the world's first 420 kV LPIT with cast resin embedded sensors and clean air insulation, replacing conventional current and voltage transformers. The LPIT will offer new digital possibilities in current and voltage metering and additional functions such as power quality measurement and will help to significantly reduce the size and copper cabling of SF6-free GIS solutions. Wider project impact 270 replications of the project throughout Europe and worldwide are planned by 2032, for both existing GIS installations (as replacements) and for new substations. The project is part of the Siemens Energy roadmap and will serve as a blueprint for technology transfer, e.g. to even higher voltage levels. Project funding Created in 1992, the LIFE program is the EU’s funding vehicle for the environment and climate action. To date it has co-financed more than 6,000 projects helping Europe to become greener, and since 2021 it has included the Clean Energy Transition sub-program. As part of the LIFE program, the EU contributes just over 4.1m euros as part of an overall budget of over 6 million euros.
