Why Kosmos Energy’s Yakaar-Teranga gas could quietly reshape Senegal’s energy mix

With the Yakaar-Teranga gas development, Kosmos Energy is working on a domestic-focused project that could change how Senegal powers its homes and industry. What the field can deliver, where the hurdles lie, and why investors still pay attention.

Yakaar-Teranga, the large gas discovery offshore Senegal operated by Kosmos Energy, is one of those projects that sounds abstract on paper but could become very tangible in daily life - in the light that stays on, in factories that finally run reliably.

What Yakaar-Teranga aims to deliver

Yakaar-Teranga is a deepwater gas discovery in the Cayar Offshore Profond block, around 95 kilometers off the coast of Dakar in water depths of roughly 2,600 meters. Kosmos discovered Yakaar in 2017 and Teranga in 2016, both in Senegalese waters.

The development is planned as a phased project focused on supplying gas primarily to the domestic market, rather than exporting most volumes as LNG. Senegal’s government has repeatedly highlighted the goal of using this gas to replace expensive fuel oil and diesel in power generation.

Reserves, scale and project concept

Kosmos has described Yakaar-Teranga as holding an estimated 25 trillion cubic feet of gas in place, with roughly 15 trillion cubic feet considered recoverable. That is a scale that, if fully developed, could cover Senegal’s gas demand for decades and still leave room for some export volumes.

The concept envisions subsea wells tied back to offshore facilities, with a pipeline bringing gas to an onshore hub near Dakar for processing and distribution to power plants and industry. Unlike mega-LNG export projects, the first phase is designed to be smaller and more modular, which should keep upfront capital spending in check.

How it fits into Senegal’s energy story

Today, many households and factories in Senegal still depend on imported fuel oil and diesel, which makes electricity both expensive and vulnerable to price swings. Domestic gas from Yakaar-Teranga could allow cheaper, more predictable power generation over time.

For private consumers this would not be visible as a shiny gadget, but as fewer blackouts and less reliance on noisy diesel generators in courtyards and workshops. For industry, stable electricity is a precondition for scaling production and attracting investment.

Timelines, partners and regulatory steps

Petrosen, the Senegalese national oil company, holds a significant stake and sees Yakaar-Teranga as a strategic lever for energy security. Kosmos has been working with the government on defining a development plan that matches domestic demand growth and financing capacity.

Kosmos has stated that a phased development could start with a first phase of up to 150 million standard cubic feet per day of gas to the domestic market. A final investment decision will depend on aligning commercial terms, gas pricing and fiscal conditions acceptable to both the state and the partners.

What makes it different from Tortue LNG

Unlike Greater Tortue Ahmeyim, the cross-border LNG project between Senegal and Mauritania where Kosmos is also a key partner, Yakaar-Teranga is designed with a "domestic-first" mindset. That means less focus on global LNG markets and more on local power plants and industry.

This orientation could make revenues steadier but less explosive when global gas prices spike. For Senegal, that is a feature, not a bug - the country wants reliable supply and stable pricing rather than riding every commodity cycle.

Risks, delays and what can go wrong

Deepwater gas projects are long-haul efforts, and Yakaar-Teranga is no exception. Cost inflation in offshore services, shifting fiscal terms, or political changes could slow progress or force redesigns. Financing conditions have also tightened for fossil fuel projects globally in recent years.

On top of that, demand planning is tricky. Senegal must decide how fast it can realistically build gas-fired plants and industrial users to take the volumes. Overbuilding capacity would strain public finances; underbuilding would strand reserves in the ground.

What this could mean for Kosmos

For Kosmos Energy, Yakaar-Teranga sits alongside Tortue, U.S. Gulf of Mexico assets and other West African projects as part of a gas-heavy portfolio. A sanctioning of Yakaar-Teranga would extend Kosmos’s growth runway in Senegal beyond the initial LNG phase at Tortue.

From an operational perspective, Kosmos can reuse knowledge and relationships from Tortue, but Yakaar-Teranga’s domestic angle also forces the company deeper into questions of local infrastructure, regulation and social impact. That may complicate negotiations but can deepen the strategic partnership with Senegal.
