Services Industriels de Genève (SIG)

Services Industriels de Genève, commonly known as SIG, is the publicly-owned utility provider for the canton of Geneva, supplying electricity, gas, water, thermal energy, and fiber-optic internet to over 500,000 residents and businesses. For arrivals relocating to Geneva, SIG is the established provider for essential utilities that every household must connect before moving in, making it an unavoidable part of the relocation process rather than a choice among alternatives.

SIG's role in Geneva's utilities infrastructure

SIG is not a commercial company selecting which customers to serve. As the public monopoly utility provider for Geneva, SIG delivers electricity, gas, water, thermal energy, and supporting infrastructure to all residents and businesses within the canton. Every person establishing a household in Geneva must open an account with SIG for electricity, gas, and water service. The company describes itself as serving 500,000 people in the canton of Geneva and being "one of the principal employers of the canton." SIG is also responsible for wastewater treatment and waste valorization, though these services operate behind the scenes for residents and do not require separate customer action during relocation.

Electricity and renewable energy

SIG publishes that 100 percent of its electricity supply comes from renewable sources, a significant advantage for environmentally conscious arrivals and a key differentiator from Switzerland's mixed energy mix. This renewable commitment appears on SIG's main pages and represents a core organizational value. The company offers various customer segments including residential customers, craftspeople and self-employed workers, businesses, municipalities, real estate managers, and partners, indicating that its infrastructure serves the full spectrum of Geneva households and organizations. The site does not specify the renewable mix (hydroelectric, solar, wind, or other sources), nor does it publish average household electricity costs or rate structures, leaving cost comparison to customer inquiry.

A customer portal exists for account management under the brand "Mon compte SIG," and the company offers a dedicated support application available for iOS and Android called "SIG & moi" (SIG and me), though the main website indicates this app is optimized for residential customers only. This mobile application provides an alternative to web-based account access and suggests that SIG is investing in modern customer interface design rather than relying solely on desktop-era portals.

Water service

SIG supplies water to Geneva residents, and the site states that 91 percent of Geneva residents drink Eau de Genève, the municipal water supply. This statistic indicates widespread adoption of the public water service, though the site does not publish rates, quality reports, or treatment standards. The company handles water distribution, billing, and maintenance of water infrastructure throughout the canton. Like electricity and gas, water service is mandatory for all households.

Fiber-optic internet

SIG offers fiber-optic internet service as part of its utility portfolio. The site does not publish speeds, pricing, or service tiers on the main pages shown. The company bundles internet availability within its core infrastructure role as a utilities provider, making fiber-optic internet a fourth essential utility for modern households. No information about activation times, minimum contracts, or service level agreements appears on the accessible pages.

Contact and support infrastructure

SIG provides an emergency contact number for urgent issues: 022 420 88 11, available for urgent situations. The company maintains separate portals for different customer types (residential, craftspeople, businesses, municipalities, real estate, and partners), suggesting that customer service may be segmented by business category. The site mentions a construction information portal (Infos chantiers) for customers affected by infrastructure work.

The company operates a client portal ("Mon compte SIG") where customers access their account, view usage, and manage billing. A dedicated online help area exists, and the site references an "Espace client SIG" (SIG customer area) for account access. The help documentation states that the customer portal is not optimized for mobile navigation, though the SIG & moi app is available as a mobile alternative for residential customers.

Environmental and strategic commitments

SIG describes itself as "an actor committed to the ecological transition" and emphasizes this commitment on its main informational pages. The company offers waste valorization and energy efficiency programs, though the site does not detail which of these programs are available to residential customers. SIG manages "smart district development" as part of its infrastructure vision for Geneva, alluding to smart metering, distributed energy, or other modern utility technologies, but the site does not specify what smart district services or costs apply to residents.

The company publishes careers information and maintains institutional pages covering strategy, values, and organizational information. It maintains social media presence on Facebook, YouTube, LinkedIn, and Instagram, though these channels are not described as customer service channels on the main site. The company notes that its website was designed with low environmental impact, suggesting an organizational commitment to sustainability in its digital operations as well.

Who must use SIG and what is not addressed

Every resident in the canton of Geneva establishing a household must open accounts with SIG for electricity, gas, and water, as these services are monopolies within the canton. Relocating residents cannot choose an alternative provider. The company's position as the mandatory utility supplier is both reassuring and limiting: reassuring because there is no risk of choosing the wrong provider for Geneva, limiting because there is no competitive alternative if service or pricing are unsatisfactory.

The critical gap for arriving residents is that the site publishes no pricing, no service activation timeline, no documentation requirements for opening an account as a non-citizen or someone without Swiss banking established yet, and no process steps or online account-opening form. The site provides no FAQ covering common relocation questions such as how someone without a Swiss residence permit can establish service, what identification or proof of tenancy is required, how to transfer service if moving between addresses within Geneva, or what payment methods are accepted. Arrivals from countries where utility setup requires in-person visits will find Geneva's online-first approach potentially simpler, but the lack of guidance makes it unclear whether that path is actually available for non-residents.

The site also does not clarify whether service can be opened remotely from abroad, what timeframes to expect between application and connection, or whether temporary setups are possible for short-term rentals or transitional housing during the relocation process. Many arrivals spend weeks or months in temporary housing before securing permanent residence, and SIG's site does not address how to navigate utilities during that phase. The customer portal is said to be not optimized for mobile access, which may complicate account setup for arrivals using only smartphones during the moving process. For someone landing in Geneva with a suitcase and needing utilities connected within days, SIG's informational site would necessitate a phone call to the emergency line or a visit to a physical office, both of which may present language or scheduling barriers during a busy relocation period.
