Revenue model

1. Electricity supply and distribution: SWG supplies electricity to residential, commercial, and industrial customers in Grenchen and surrounding municipalities. Revenue comes from energy sales, network usage tariffs, and measurement fees. From 2026, a new single electricity product is offered containing at least two-thirds renewable Swiss energy.
2. Gas supply and distribution: SWG supplies natural gas and biogas to customers. Per July 2026, all gas customers receive a uniform product containing 15% biogas, with gradual biogas content increases planned. Gas prices are separated into network usage and energy costs for transparency.
3. Water supply: SWG supplies drinking water sourced from 22 spring sources in the Grenchenberg tunnel and groundwater from Kyburg, Obergerlafingen, and Recherswil.
4. Heating / Wärme: SWG offers heating solutions including gas/biogas heating, district heating networks (Nahwärmeverbünde), and heat pump solutions. Contracting services are offered where SWG plans, installs, finances, operates, and maintains heating systems for customers.
5. Heating Contracting: SWG finances, installs, operates and maintains heating systems. Customers pay a contracted annual fee plus service contract costs and energy consumption. After 15 years, the heating system transfers to the property owner.
6. Electric vehicle charging infrastructure: SWG operates public EV charging stations in the Grenchen region, charging for electricity consumed.
7. Renewable energy production: SWG is developing its own renewable energy production including wind power (Windpark Grenchenberg) and expanded biogas production (Biogasanlage Witi).

It is also developing renewable energy production assets including the Windpark Grenchenberg wind project and the Biogasanlage Witi agricultural biogas facility.

Product overview

SWG Grenchen is a regional multi-utility company (Energieversorgerin) serving Grenchen and surrounding municipalities in the cantons of Solothurn and Bern, providing electricity, gas, water, and heating services. Its core product portfolio centers on the supply of electricity, natural gas with blended biogas, and drinking water, alongside a growing portfolio of renewable energy production assets. SWG offers three tiers of self-consumption community products (ZEV, vZEV, and LEG) that enable solar prosumers to share locally produced electricity with neighbors. Supporting services include a Smart Grid development initiative (intelligent power network), public EV charging infrastructure, gas heating contracting, district heating (Nahwärme), public lighting management, and the Windpark Grenchenberg wind power project. Customers interact with SWG through a digital customer portal, the SWG Poscht online magazine, and an integrated Swisscharge EV charging network. SWG also produces its own biogas from sewage sludge and is expanding into agricultural biogas (Biogasanlage Witi) from manure and green waste.

Products and services

• Standard Electricity Supply (Strom) Round-the-clock electricity supply to residential and commercial customers in Grenchen and surrounding municipalities. From 2026, offered as a single unified standard product sourced at least two-thirds from renewable Swiss energy, replacing the prior three-product structure.
• Gas Supply with Biogas (Gas / Biogas) Natural gas supply with a blended biogas component. From July 2026, a unified product with 15% biogas is offered to all customers. Customers in Bern canton municipalities may opt for a 50% biogas blend. SWG also produces its own biogas from sewage sludge and is expanding to agricultural biogas from manure and green waste.
• Water Supply (Wasser) Drinking water supply to Grenchen and surroundings from 22 spring sources in the Grenchenberg (tunnel sources, approximately 90% of supply) supplemented by groundwater from Kyburg, Obergerlafingen, and Recherswil. Spring water requires no treatment; groundwater is disinfected with UV radiation. SWG takes 180-300 water samples per year and analyzes them in its own laboratory.
• District Heating (Nahwärme) District heating solutions offered by SWG as part of its heating strategy. SWG handles planning, implementation, operation, and financing. Investment costs are included in the contractually agreed heating prices.
• Gas Heating Contracting (Wärme-Contracting) SWG plans, installs, finances, operates, and maintains gas heating systems on behalf of customers. Customers pay a contracted annual fee plus service contract costs and energy consumption. After 15 years, ownership transfers to the property owner. Includes full service and maintenance.
• Public EV Charging Stations SWG operates public electric vehicle charging stations in the Grenchen region, powered exclusively by renewable electricity. Integrated into the Swisscharge network for discoverability and payment via the Swisscharge app.
• Network Connections and Grid Access Operation and maintenance of the electricity, gas, and water distribution networks in Grenchen and surrounding municipalities. Includes grid connections, provisional connections, and sovereign inspections.
• ZEV Self-Consumption Community (Zusammenschluss zum Eigenverbrauch) Self-consumption community model where solar power produced on a building or site is shared among participants connected to the same grid connection point. Participants receive no separate SWG electricity bill; the ZEV handles internal metering and billing through a third-party service provider.
• vZEV Virtual Self-Consumption Community (Virtueller Zusammenschluss zum Eigenverbrauch) Virtual self-consumption community model enabling solar power from a building to be sold to residents in neighboring buildings within the same transformer station area. SWG provides smart meter data (15-minute values) to the billing service provider.
• LEG Local Electricity Community (Lokale Elektrizitätsgemeinschaft) Local electricity community model allowing solar power producers to sell electricity to households and businesses across a neighborhood or the entire municipality. Reduces grid usage fees by 20-40% for participants (40% within the same transformer circuit, 20% outside). SWG's distribution network is divided into three LEG zones determined by the city's three substations.

Partnerships

Four partnerships are on record, tiered core and minor.

• GAGNET AGcoreTechnology or Integration · 1 August 2025SWG and GAGNET AG signed a fiber optic usage agreement in August 2025. GAGNET provides fiber optic infrastructure that serves as the backbone of SWG's Smart Grid strategy, enabling real-time monitoring and control of the electricity grid. The agreement secures SWG the right to use fiber optic connections to every building in Grenchen.
• ELEKTRON AGcoreStrategic or Co-development PartnerSWG was the first Swiss energy company to participate in ELEKTRON AG's pilot project for circular LED street lights (Kreislauf-Leuchten). In this project, only the LED module and control gear are replaced while retaining existing aluminium housings. ELEKTRON AG developed the concept; SWG provided operational testing and feedback.
• VEBO GrenchenminorStrategic or Co-development PartnerVEBO Grenchen, an organization providing meaningful work for people with disabilities, performs the physical retrofitting of the circular LED street lights as part of the Kreislauf-Leuchten project. This creates regional value and employment while SWG provides the lighting infrastructure.
• ARA Regio Grenchen (Wastewater treatment plant)coreStrategic or Co-development PartnerSWG has produced biogas from the wastewater sludge of ARA Regio Grenchen for several years. This existing biogas production will be expanded with the new agricultural biogas plant (Biogasanlage Witi) on the ARA site.
