Siemens boosts climate-friendly power distribution in Davos
Davos’ power utility commissions latest blue GIS system from Siemens using eco-friendly insulating gas
This is the most reliable single pole encapsulated medium-voltage switchgear globally, adding to Siemens’ pioneering blue GIS portfolio introduced by the company in 2018
Secure and reliable power supply for up to 40,000 people in Europe’s highest city at 1,560 meters above sea level
Electrification X combines the real and the digital worlds in Siemens Xcelerator IoT-SaaS offering for electrification and automation
Siemens has installed and commissioned the
world’s first 8DAB 24, the groundbreaking blue GIS medium-voltage system, in
the Alpine town of Davos, Switzerland for its customer EWD Elektrizitätswerk
Davos AG. The switchgear system, which uses Clean Air as insulating gas instead
of sulfur hexafluoride (SF6), is deployed in the Dorf substation in Davos,
securing reliable power supply for up to 40,000 people. The installation of
this 24kV circuit-breaker switchgear is an important step towards a
climate-friendly and smart power distribution in Davos. The Fluor-gas-free blue
GIS-portfolio was launched by Siemens ahead of EU regulations, serving as another proof point
of the company’s focus on sustainability across its portfolio. Siemens introduced the first SF6-free solution around
seven years ago, since then installed many more successfully and this being the
latest addition.

“If we want to achieve our net-zero targets, we need to
make power grids future ready with innovative, eco-friendly technology,” said
Matthias Rebellius, Member of the Managing Board of Siemens AG and CEO of
Siemens Smart Infrastructure. “Therefore, it is essential to invest in the
continued expansion of power grids. I am pleased that our long-standing
customer EWD is using our pioneering switchgear technology that paves the way
for climate-neutral and smart power distribution in Davos.”
“SF6
was never ideal for the environment,” said Andy Kollegger, CEO of EWD. “There
was no doubt in our minds: If there is an alternative on the market that has
the same functionality but without this disadvantage, we will switch to it.”
With
over 1.3 million overnight guests in 2023, Davos is one of Switzerland’s
biggest tourist destinations. It is also the venue for the World Economic Forum
(WEF) that sees almost 3,000 guests flocking to the town each year. While close
to 12,000 residents live in the highest town in the Alps year-round, Davos
accommodates over 40,000 people during high season. EWD Elektrizitätswerk Davos
AG operates three substations, 168 transformer stations, 154 kilometers of
medium-voltage grid and 300 kilometers of low-voltage grid in the Davos
grid area.
Reliable
power supply is essential to a well-functioning infrastructure. At the heart of
sustainable power distribution is switchgear. Its applications include
substations where it connects power generators and large power consumers, such
as industrial plants or data centers, to the power grid. Another important role
of switchgear is monitoring and protecting power grids, for example against
short circuits. The Clean Air used as an insulating medium in the blue
GIS portfolio consists of natural components of ambient air, making it climate-friendly,
extremely stable, non-toxic, non-flammable, and suitable for all operating
temperatures.
In
addition, the blue GIS switchgear is equipped with smart sensors and
standardized interfaces for Electrification X. Part of Siemens Xcelerator, Electrification
X is a comprehensive IoT suite that provides solutions to challenges faced by
public and private power grid operators. It improves energy efficiency and
enables a seamless digital and sustainable transformation.
