Blue high-voltage products

Decarbonizing the energy industry is about more than switching to renewable sources. To achieve Zero Global Warming Potential (GWP), it's essential we make the transmission of power as clean and green as its generation. This means eliminating F-gases from electrical switchgear – particularly SF₆, a gas 24,300 times more climate-hostile than CO₂.

Our Blue portfolio uses clean air and vacuum switching technology instead. Zero F-gases, Zero toxicity and Zero harm to human health and the environment.

Less global warming potential is not good enough. It has to be Zero, because 1% global warming potential is still global warming potential. It has to be Zero and it has to be now.

Our Blue products use vacuum switching technology and clean air insulation to produce Zero harmful emissions - and without having to compromise on performance or economic feasibility. With over 10 years of experience in high-voltage vacuum switching, we have been able to maintain outstanding levels of technical performance and low lifecycle costs while reducing our ecological footprint to an enormous extent. Blue is already the perfect choice for substation products. And with the help of our strong partnerships, we can develop and implement it even further and faster.

Collaboration is crucial in cutting climate-harming emissions – and the LIFE Blue project GIS 420 kV is the latest example of how this works in practice.

Backed by EU funding and in partnership with Elia, operator of the electricity transmission network in Belgium, the LIFE Blue project is set to demonstrate for the first time the economic viability of a climate-friendly and completely F-gas free 420 kV GIS.

At Siemens Energy, we see a partnership as much more than a simple supplier-client relationship. It goes way beyond the placing and delivery of an order. Rather, it's a dose alliance between both parties. We work together towards a shared goal, developing the end solution by exchanging ideas and expertise at every stage.

This collaborative, interactive approach is mutually beneficial. Solutions can be shaped to meet particular requirements and the optimal set-up is reached more quickly.

We delivered 160 8VM1 Blue Gis bays to this huge project off the coast of the Netherlands, which is capable of supplying up to three million Dutch households with green energy.

"Being CO₂-neutral is the future and the target for our customers in the offshore wind market, as well as for us at Siemens Energy." – Ann-Sofie Bonde Mortensen, Global Vertical Sales Manager Offshore Wind, Siemens Energy.

The digitally-enabled 145 kV 3AV1 Blue circuit breakers installed at the Hesseln substation incorporate Sensgear^TM, a cloud- based monitoring solution that provides data to improve grid operation, asset management and maintenance.

"The medium-term replacement of the insulating gas SF₆ is an essential component of the decarbonization strategy of our E.ON Group." – Dr. Markus Obergünner, Senior Vice President High Voltage Grid, Westnetz GmbH.
