To natural gas tariffs

Which tariff is right for me?

As a household, you can choose between the bio natural gas “SUDgaz Green” and the classic natural gas “SUDgaz Classic”.  With bio natural gas, you can choose between 50% or 100% biogas. The rest is conventional natural gas.

What are the advantages of natural gas?

Natural gas is a natural energy source that guarantees you numerous advantages without having to make any other concessions.

Natural gas supports the energy transition
The possibility of adding biogas to conventional natural gas further reduces the already low emissions.

Natural gas is practical
Compared to other energy sources such as fuel oil or wood pellets, you don’t need to keep ordering or store natural gas. No tank or storage space is needed.

Natural gas is convenient
It feels good to live in properly heated rooms. Reliable heating technology, adapted to your needs, ensures comfort in your home.

Natural gas is environmentally friendly
Natural gas and fuel oil are fossil fuels that emit CO2. when burned. However, the combustion of natural gas emits much less CO2 and much less particulate matter than the combustion of heating oil. The CO2 emissions of your heating system can be reduced by 24% by switching to the environmentally friendly energy source of natural gas.

Natural gas is economical
You can count on proven, efficient natural gas technologies that are continually being further developed – all at reasonable investment costs and affordable consumption prices.

Natural gas is clean
Not only is natural gas an efficient and convenient way to heat your home, it also has environmental benefits: natural gas is the fossil fuel with the lowest emissions. Like biogas, natural gas improves the environmental balance – whether for heating or cooking.
