Global technology giant Siemens has made significant strides in sustainable power distribution, as evidenced by installing its innovative blue GIS medium-voltage system in Davos, Switzerland.

The development showcases Siemens' commitment to providing eco-friendly solutions for energy infrastructure, aligning with the growing demand for sustainable technologies in the power sector.

A climate-conscious solution for Davos

Davos, Europe's highest city at 1,560 metres above sea level, is renowned for hosting the World Economic Forum's (WEF) annual summit. The upcoming summit, scheduled to begin on 20 January, makes the timing of this installation particularly significant.

The alpine town experiences substantial fluctuations in energy demand, with its population swelling from 12,000 residents to over 40,000 during peak seasons and accommodating more than 1.3 million overnight guests in 2023.

Elektrizitätswerk Davos (EWD), the local utility company, commissioned Siemens to install the world's first 8DAB 24 blue GIS medium-voltage system at the Dorf substation. The decision aligns with EWD's commitment to sustainable energy solutions.

Andy Kollegger, CEO of EWD, explains the rationale behind this transition: "SF6 was never ideal for the environment. There was no doubt in our minds: If an alternative on the market has the same functionality but without this disadvantage, we will switch to it."

Innovating for reliability and sustainability

The 8DAB 24 switchgear system, part of Siemens' blue GIS portfolio, represents a significant advancement in eco-conscious power technology. Unlike traditional switchgear that relies on sulphur hexafluoride (SF6), a potent greenhouse gas, Siemens' system uses a Clean Air insulation medium.

The innovative technology comprises natural air components, ensuring it is non-toxic, non-flammable and suitable for various operating temperatures.

Jon Turner, Head of Siemens Distribution Systems Businesses for the UK and Ireland, emphasises the importance of this technology: "The climate-neutral insulation medium used, which is comprised exclusively of natural components from ambient air, is a game changer, removing the need for fluorinated gases."

Matthias Rebellius, CEO of Siemens Smart Infrastructure, underscores the significance of this innovation in achieving sustainability goals.

"If we want to achieve our net-zero targets, we need to make power grids future-ready with innovative, eco-friendly technology," he says. "I am pleased that our long-standing customer EWD uses our pioneering switchgear technology that paves the way for climate-neutral and smart power distribution in Davos."

Bridging the digital and physical worlds

Siemens' blue GIS technology addresses environmental concerns and incorporates smart features to enhance operational efficiency.

The switchgear has smart sensors and interfaces connected to Siemens' Electrification X platform, part of the company's Xcelerator Internet of Things suite.

The digital ecosystem enables real-time monitoring, optimises energy efficiency and addresses operational challenges for public and private grid operators.

Meeting high expectations in a unique setting

Davos' energy infrastructure is extensive, comprising three substations, 168 transformer stations and more than 450 kilometres of power lines. The town's reliance on renewable energy sources necessitates robust and reliable systems.

Siemens' blue GIS technology ensures minimal environmental impact while supporting this critical infrastructure, from homes and businesses to world-class facilities hosting global events like the WEF.

EWD's commitment to sustainability extends beyond power distribution. The utility has provided renewable heat and hydropower to its customers for more than 130 years, which is crucial in ensuring Davos' energy resilience. The adoption of Siemens' blue GIS solution in Davos reflects a broader shift towards greener energy systems prioritising long-term ecological impacts without compromising performance or reliability.

As the world moves towards more sustainable energy solutions, innovations like Siemens' blue GIS technology pave the way for a cleaner, more efficient future. 

Matthias Rebellius aptly concludes: "It is essential to invest in the continued expansion of power grids."

This installation in Davos serves as a testament to the potential of eco-friendly technologies to transform power distribution systems worldwide.
