It’s Day Zero for Bergen Port

Cruise ships used to power up in the harbour using their diesel engines. Now, thanks to BKK Nett and Blue switchgear technology from Siemens Energy, they use only clean power. Zero greenhouse gas emissions, zero F-gases and zero health impact. It's their Day Zero. Let's plan yours.
We didn’t want to make a decision today that would embarrass us two years down the line.
Jens Skår, Head of Future Grid, BKK Nett


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.

Sustainability by technology

The Blue portfolio: not just zero F-gases, but zero reduction in performance

In 2019 global carbon emissions hit an all-time record high of 36.8bn metric tons. To address this, 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. The outstanding technical performance and low lifecycle costs make Blue the perfect choice for substation products.

Our Blue portfolio makes it possible to modernize and expand the existing power grids at the highest level of safety and to simultaneously reduce our ecological footprint to an enormous extent without having to compromise on performance and economic feasibility. The combination of vacuum switching technology and clean air insulation reduces emissions while greatly increasing the recycling rate – without maintenance. The outstanding technical performance and low lifecycle costs makes it a perfect choice for substation products. The technology is available for gas-insulated switchgear, circuit breakers and instrument transformers all with absolutely zero CO2 equivalent emissions over the lifetime of the equipment.

Blue products: made with zero compromise


Blue goes digital: why Sensgear makes sense.

Netze BW, Burladingen, Germany

Zeroing in on clean energy in Burladingen

As the largest distribution system operator in Baden-Württemberg, Netze BW wanted to design a substation with ecological, yet economically sustainable components. With the previous delivery of a CO2-neutral circuit-breaker for a substation in Nördlingen, Siemens Energy had already proven its competence in environmentally friendly products. Combined with a future-oriented vision of a digitally enabled substation, Siemens Energy convinced Netze BW to implement a complete digital substation in Burladingen; where switchgear becomes Sensgear® and a transformer becomes a Sensformer®.
Netze BW is once again a pioneer, through the application of innovative technologies in digital and eco-efficient substations.
Martin Konermann, Managing Director of Netze BW GmbH
Fingrid is zeroing in on zero

A Finland first: a major new investment in switchgear with zero F-gases

Siemens Energy has been awarded the contract to deliver ten bays of Blue gas-insulated switchgear (GIS) to Fingrid, Finland’s transmission system operator. It will be the first GIS in Finland that replaces F-gases with clean air, a pure mixture of nitrogen and oxygen with zero potential for global warming. This will be the most significant Blue installation to date.
With Siemens Energy we have found a reliable partner that offers innovative products with absolutely zero climate-harming fluorinated gases.
Timo Kiiveri, Senior Vice President at Fingrid
