The heart of the SIG strategy
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
The decrease in the consumption of all energies: electricity and fossil fuels
The development of solar energy
The development of wind energy
The development of thermal solutions in general and geothermal energy in particular
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.
Geothermal energy is a source of local energy from the subsoil that is clean, renewable and continuously available, while having many thermal and electrical applications. There are various stages of surveys and subsoil drilling involved in its development. Knowledge of the Geneva subsoil is therefore a prerequisite. Therein lies the challenge presented by the GEothermie 2020 programme, led by the State of Geneva and implemented by Services Industriels de Genève (SIG). It is in this context that a detailed 3D mapping of the Geneva subsoil has been undertaken since 2014, revealing conditions that are particularly favourable for geothermal energy. As of 2018, this preliminary prospecting will be followed by drilling to a medium depth (over 1,000 m).
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.
For the past 10 years, 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, 135 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.
IMPACT is a crowdfunding platform.
Its principle is simple: Genevans choose to invest in a project proposed by associations or companies of the canton, to promote the energy transition. They benefit from entertaining or tasty rewards!
