Energy transition

The energy transition is at the heart of the SIG strategy and actions in Geneva. It refers to the transition from our current mode of production and consumption to a new energy model which is more sustainable and more economical. The energy transition is essential due to an extensive number of factors, such as the depletion of natural resources and the respect for the environment.

The heart of the SIG strategy


For several years, SIG has made the energy transition the foundation of its corporate strategy. It is necessary to act on several levels:


    Changing our business models and organisations


    The energy world is undergoing a total revolution. From a hyper-centralised model, it is changing towards one where there are a multitude of stakeholders of all sizes, which are all involved in an interconnected and dynamic system. The energy transition is the path towards this new world that is pluralistic, multifaceted, resolutely efficient and totally renewable. SIG is committed to making this shift in a proactive and committed way, alongside and through its customers and partners. 


    Changing the habits of individual consumers 


    The progressive evolution of behaviours and lifestyles both follows and drives these systemic changes. Households, municipalities and businesses experiment and invent a host of micro-revolutions that enable comfort levels to be maintained, while putting a stop to our energy and our earnings from being wasted. SIG is committed to continuing to stand by its customers, so as to encourage, support and facilitate these initiatives!

bon à savoir

Good to know


In Geneva, we have a strong commitment: The canton has confirmed its “General Energy Conception”, which is based upon a 2,000-watt, nuclear-free society as a long-term goal. It incorporates the objectives of the Federal Council's Energy Strategy 2050, foremost amongst which is the increase in the share of renewable energies and a reduction in consumption.
As the industrial arm of the implementation of the General Energy Conception, SIG leads or participates in all projects that are essential for the definitive implementation of our energy strategy.

Concrete actions and projects

Actions and projects

SIG plays a leading role in Geneva’s energy transition in by targeting the following areas for taking action:

  • vu
    The decrease in the consumption of all energies: electricity and fossil fuels
  • vu
    The development of solar energy
  • vu
    The development of wind energy
  • vu
    The development of thermal solutions in general and geothermal energy in particular
  • vu
    The optimal utilisation of our dams

SIG intends to double solar production in the canton by 2023. This will be achieved by:

  • The construction of photovoltaic plants: in 10 years, solar power has increased by a factor of 10. The canton now has more than 1,200 solar plants.
  • The sale of Électricité Vitale Vert, which enables the financing and the development of new photovoltaic facilities in Geneva.
  • The promotion of your solar production: SIG encourages all Geneva residents (private, municipalities, businesses) to develop their own facilities and buys their solar energy at a competitive price.


Renewable thermal energy

SIG will achieve at least 50% of the Canton's renewable heat generation goals.
For this, we utilise the heat networks at a district level or larger, and decentralised renewable heat at the building or villa level.

The new heating and cooling systems that have been put in place rely either on the conversion of waste heat (Cheneviers-CADIOM, for example), or on renewable energy methods such as medium-depth geothermal energy or systems requiring a heat pump. They can also use natural gas.

Since 2007, SIG has been running the éco21 project, whose goal is to offer concrete solutions to individuals, municipalities and businesses for reducing their energy consumption.

Since the start of the programme, 205 GWh of electricity have been saved every year in the Canton of Geneva and, by 2025, the goal is to reach 300 GWh, which is the equivalent of the annual consumption of 100,000 households, or of the consumption of the City of Geneva’s residents.

SIG continues with this ambitious programme for saving energy and CO2 emissions by offering products and services to its customers, and by developing partnerships with local companies and even other industrial service providers.

Recovering wind energy to convert it into electricity has been a major challenge throughout the history of renewable energy. In fact, a single 3 MW wind turbine produces the equivalent of 2,000 households’ consumption annually, which is about the consumption of the municipality of Satigny’s population.

SIG participates in the development, construction and operation of wind farms in Switzerland when these present both energy and economic benefits, and provided that their environmental integration is optimised.



Réduire la quantité de déchets incinérés du canton de Genève

  • Mettre en œuvre un programme permettant de réduire la quantité de déchets produits dans le Canton.
  • Minimiser les rejets induits par le traitement des déchets.
  • Valoriser l’énergie produite par l’incinération de manière optimale.

SIG s’engage à améliorer le tri, la qualité du recyclage et réduire la quantité de déchets incinérés du canton de Genève de 195'000 à 160'000 tonnes par an à l’horizon 2024.

SIG s’engage également à mettre en service d’ici 2024 une nouvelle usine d’incinération des ordures ménagères générant 450 GWh de chaleur par an, soit la consommation de près de 47'000 Genevois·es se chauffant partiellement avec de l’énergie fossile.
