Growing market demand for decarbonization / SF6-free high-voltage products



4

2020-08

Growing market demand for decarbonization / SF6-free products

• Under the UNFCCC (United Nations Framework

Convention on Climate Change) Paris Agreement

signed by 189 countries of the world in 2015, it was

agreed to limit anthropogenic global warming to well

under 2º centigrade.

• Each country must determine, plan and regularly report

on the contribution that it undertakes to reduce global

warming by mitigating its greenhouse-gas-emissions.

• SF6 is a strong green-house gas with a CO2 equivalent

of 23,500.

• Since global carbon emissions in 2019 hit an all-time

high record of 36.8 billion metric tons, the pressure on

power utilities to expedite their decarbonization efforts

is increasing!

Total Cost of

Ownership (TCO)

Digitalization

Health & Safety

• High demand for

digitalization triggering

utilities to enhance digital

monitoring of their T&D

assets & installed base

• High public awareness of

decarbonization

• Growing demand by utilities

for independence from

OEM- specific maintenance

requirements.

• Growing demand for

maintenance-free products

which ensure lowest

operating costs and lowest

TCO.

Growing demand for health & safety, digitalization & low TCO

• High focus by power utilities on reducing health & safety risks

caused by leakage of toxic (greenhouse) gases and their by-

products.

Growing number of companies going for SF6-free

“TenneT developed an SF6 policy, striving to minimize usage and emissions of SF6. Target is to reduce relative SF6emissions by 20% in 2020 compared to 2015.” TenneT Germany / Netherlands (Annual Report 2014)

“Our target is to reduce our greenhouse gas emissions by 45% by 2020 and 80% by 2050 compared to 1990.”

National Grid UK (Annual Report 2014/15)

“RTE launched a proactive initiative to reduce leakage of SF6, a gas with strong greenhouse effect.”

RTE France (Annual Electricity Report 2014)

“Responsibility on Environmental Protection and Low Carbon Emission: responsible for environment.”

SGCC China (Social Responsibility Report 2013)

“Building on ongoing sustainability efforts, Pacific Gas and Electric Company (PG&E) announced a new goal to reduce 1

million tons of greenhouse-gas emissions from company operations through 2022 … Through the company's operational

plans, PG&E aims to: Make its facilities more energy efficient and sustainable.“ PG&E California / USA (Press Release – 12.07.2018)

“The large proportion of hydropower in Norway’s power system makes it the world’s most climate-friendly system. Now we

are investing in a pilot project which uses an environment friendly alternative to SF6 gas, thus becoming the first project of

its kind in the world with this technology”. BKK Nett CEO Wenche Teigland (November 2018)

2020-08

For Siemens Energy to classify a product as ‘Blue’, it has to meet a series of strict criteria.

Our environmental protection and sustainability requirements are listed below.

Siemens Energy Blue high-voltage products Philosophy & definition

No F-gasesBlue products are out of

scope of any kind of F-gas

regulation (no SF₆ or other F-gases contained)

Zero greenhouse gas

emissionsBlue products’ have zero Global

Warming Potential (GWP)

Leading position in terms

of sustainabilityBlue products give high public and

market acceptance due to greenhouse

gas-free operation, low maintenance

and simple end of life treatment

Use of environmentally

safe materialsMaterials and substances meet

highest health & safety standards

(e.g. REACH, RoHS in Europe)

Long lasting designBlue products’ operational life time

is expected to be more than 40

years - saving natural resources

Built-in Circular EconomyRecycling studies and defined return

schemes help to qualify blue products

for recycling loops

DocumentationBlue products provide a life cycle

analysis (LCA) and environmental

declaration (Type II) acc. to ISO 14021
