Sulgás

What Sulgás does

Sulgás (Companhia de Gás do Estado do Rio Grande do Sul) is the exclusive licensed distributor of piped natural gas in the Brazilian state of Rio Grande do Sul, operating under a state concession regulated by AGERGS. Founded in 1993 as a state-owned enterprise and privatized in 2022, the company is now controlled by Compass Gás & Energia and Commit Gás (both part of Grupo Cosan). Sulgás operates a 1,592+ km buried pipeline network reaching 38 municipalities that represent 47% of state GDP, distributing approximately 2.1 million m³/day to 112,000+ customers across industrial, commercial, residential, vehicular (GNV), and cogeneration/climate control segments. The technical infrastructure includes SCADA-based supervisory control, cathodic protection systems, pressure regulation stations, and individual metering units with remote telemetry.

The company's product portfolio spans natural gas distribution (cascaded tariff tiers from R$2.53/m³ for large industrial users to R$9.65/m³ for residential), compressed natural gas (GNC) delivered by truck to areas not yet served by pipeline, vehicular natural gas (GNV) dispensed through partner fuel stations, and biomethane blended into the network via the Bioo partnership. Sulgás is also developing the first biomethane hub in Rio Grande do Sul (Sulgás BioHub in Esteio, capacity 30,000 m³/day) and a planned 100% biomethane local network in Passo Fundo. The Corredores Verdes project deploys high-flow GNV dispensers that cut heavy-truck refueling time from 1 hour to 20 minutes.

Sulgás generates revenue through regulated, usage-based tariffs approved by AGERGS, with tiered pricing that decreases as consumption volume increases. The go-to-market combines enterprise field sales for industrial and large commercial customers with online contracting portals (contrate.sulgas.com.vc), a 24/7 SAC (0800 54 197 00), self-service client portal, and partner fuel station networks for GNV. The 2026 investment plan of R$163.7 million — approximately 4x the pre-privatization 2021 level — funds network expansion (84.4 km), a 190 km Taquari-Rio Pardo corridor, and biomethane infrastructure development, positioning the company for material customer base growth from 69,000 in 2021 to a projected 122,000 in 2026.

Revenue model

1. Natural Gas Distribution: Sulgás generates revenue primarily through the distribution of natural gas via its pipeline network. Customers are charged a combination of fixed fees and volume-based (variable) tariffs per cubic meter consumed. Tariffs are regulated by AGERGS and vary by customer segment (industrial, commercial, residential, vehicular). Revenue is consumption-based and recurring, with tariffs structured in tiers where higher consumption yields lower per-unit rates. Payment is made post-consumption via monthly invoice.
2. Biomethane Distribution: Sulgás distributes biomethane produced by partner suppliers (e.g., Bioo in Triunfo) through the same pipeline network. Biomethane is mixed with natural gas and delivered to customers, contributing to the renewable energy portion of the company's energy mix. Up to 30,000 cubic meters of biomethane per day are currently supplied.
3. Network Expansion and Connection Services: Revenue is generated from connecting new customers to the pipeline network, including construction of infrastructure such as ERU (Urban Regulation Stations), internal piping, meter installation, and equipment conversion services. The company also provides financial incentives for residential conversions.
