Tanzania announces first major gas discovery in a decade at Mnazi Bay
Energy Minister Juma Homera put 223 billion cubic feet of estimated reserves on the Kasa-1X ST2 well. Production is pitched for early November — a domestic-power story more than an LNG boom narrative.
NAIROBI / DAR ES SALAAM — Tanzania’s energy ministry on 27 October 2026 announced an estimated 223 billion cubic feet of natural gas at the Kasa-1X ST2 well in the Mnazi Bay block, Mtwara — billed as the country’s first major new gas discovery in more than a decade.
Energy Minister Juma Zuberi Homera, speaking at a ceremony carried by The Citizen, BBC Africa and Africanews, called the find a “major milestone” for a sector that already feeds most of Tanzania’s electricity. The well is a joint effort by the state Tanzania Petroleum Development Corporation (TPDC) and French producer Maurel & Prom.
What the government is claiming
Homera said Kasa-1X ST2 is expected to produce about 30 million cubic feet a day for at least ten years, with first gas pitched for early November. He also said two other Mnazi Bay wells, MB-5 and MS-2, had already lifted block production by more than 65 million cubic feet a day. More than 80% of gas from the block already goes to Tanesco plants in Mtwara and Dar es Salaam, according to ministry remarks.
Secondary reporting notes Tanzania’s existing gas resource base at about 57.54 trillion cubic feet. Against that stock, 223 Bcf is incremental domestic supply — not a rewrite of the offshore LNG mega-project map. AB24 treats the reserve and daily-rate figures as ministry-stated estimates, not as independently audited recoverable volumes.
Domestic power first — LNG talk later
Dar’s frame is energy security and industrial load growth: cut import dependence, feed power plants, and keep feedstock options open for fertiliser and petrochemicals. Homera also said TPDC is talking to four investors about small-scale LNG projects, three of them expected in Mtwara — conversations, not signed offtake trains.
Government equity in Mnazi Bay rose from 20% to 40% via TPDC in 2024, the minister said, increasing both decision rights and potential profit-gas take under the production-sharing contract. Local-content claims in the same briefing — Tanzanians as the bulk of production staff, contracts to local firms — sit in the political economy of resource nationalism, and will need payroll and tender evidence over time.
East Africa energy desk takeaway
For Nairobi and Dar markets desks, the overnight lead is narrower than the ceremony: a decade-gap discovery, a near-term production calendar, and a government that wants the story read as grid and industry fuel rather than as a new export boom. Commissioning performance in November will decide whether the headline survives contact with the manifold.
