The Tunisian Company of Electricity and Gas, known by its French acronym STEG (Société Tunisienne de l’Electricité et du Gaz), is Tunisia’s state-owned national utility responsible for generating, transmitting and distributing nearly all of the country’s electricity and piped natural gas. As a public monopoly utility, it does not operate like a conventional publicly traded company, and detailed English-language corporate information about its leadership and finances is limited.
What Does STEG Do?
STEG is Tunisia’s vertically integrated electricity and gas utility, covering generation (from thermal, and increasingly renewable, sources), high-voltage transmission, and retail distribution of both electricity and natural gas to households, businesses and industry across the country. As the dominant, state-controlled utility, it plays a central role in Tunisia’s energy policy, including the country’s efforts to expand solar and wind generation capacity as part of its energy transition plans.
How Big Is STEG?
African Business’s Top 250 ranking placed STEG 83rd by revenue among Africa’s largest companies, at roughly $1.95 billion — a scale that reflects its position as the sole supplier of electricity and gas to a country of around 12 million people, rather than the kind of competitive market share metrics used to size private-sector energy companies.
Who Owns STEG?
STEG is wholly owned by the Tunisian state and operates as a public utility rather than a shareholder-owned corporation. It is not listed on any stock exchange, and its governance sits under Tunisia’s Ministry of Industry, Mines and Energy, consistent with the structure of national utilities across much of North Africa.
Is STEG Publicly Traded?
No. STEG is a state-owned enterprise and does not trade on the Tunis Stock Exchange or any other exchange. Its finances are reported through Tunisian state and ministry channels rather than the kind of investor-facing annual reports typical of listed utilities.
Where Is STEG Headquartered?
STEG is headquartered in Tunis, Tunisia’s capital, from where it coordinates the national electricity grid and gas distribution network.
How Does STEG Compare to Its Regional Peers?
STEG plays a similar national role to Morocco’s ONEE, Algeria’s Sonelgaz, and Egypt’s state electricity holding company — all state utility monopolies responsible for keeping the lights on across their respective countries. Like several of these peers, STEG has faced periodic financial strain tied to subsidised consumer tariffs that do not always cover the full cost of generation and imported fuel, a structural challenge common to state utilities across North Africa.
What Has STEG Been in the News For Recently?
STEG has featured in regional energy coverage around Tunisia’s push to diversify its generation mix and reduce reliance on imported natural gas, including engagement with international energy technology suppliers on grid modernisation. As with other North African state utilities, STEG’s financial health and subsidy burden remain recurring topics in discussions of Tunisia’s broader public finances.
