What Société Tunisienne de l'Electricité et du Gaz does

Société Tunisienne de l'Electricité et du Gaz (STEG) is the Tunisian state-owned integrated electricity and gas utility, founded in 1962 and headquartered in Tunis. It operates as the national monopoly provider of power and natural gas services, serving 4,582,694 electricity customers and 1,070,360 gas customers across Tunisia. The company supports a 99.8% national electrification rate and maintains a workforce of 13,223 employees, with production reaching 19,311 GWh annually and developable power capacity of 4,630 MW. Its operations span generation, transmission, distribution, and end-customer supply across residential, professional, and public-sector segments, supported by multiple regional service centers, a national call center, and an online portal for billing and account management.

STEG's core technical infrastructure includes a Smart Grid program for network monitoring and management, alongside traditional generation assets spanning thermal, hydro, and renewable sources. The utility has been actively diversifying its generation mix through long-term power purchase agreements (PPAs), including 60 MW solar projects in Tozeur and Sidi Bouzid and a 75 MW wind project in El Fahs, developed with partners such as Scatec ASA and Aeolus SAS under 25–30 year offtake contracts. STEG also operates a subsidiary, STEG International, which suggests an ambition to export operational expertise to other markets, and offers services to auto-producers (independent power producers), indicating an evolving ecosystem around distributed generation.

The company's revenue model is built on regulated tariffs for electricity and gas distribution to end users, complemented by long-term PPAs with independent power producers that secure capacity without direct capex. Revenue of 5,860 million Tunisian dinars (MDT) reflects its dominant position in a captive domestic market, with pricing governed by Tunisian regulatory authorities under the oversight of the Ministry of Industry, Mines and Energy. Customer-facing operations are delivered through a hybrid physical-digital channel mix, including service centers, a call center, and an electronic portal, while compliance with Tunisia's 2025 Finance Law electronic invoicing requirements signals operational modernization of back-office functions.
