Kenya Crosses the Gigawatt Threshold in Geothermal Power — And Africa Is Watching

When Kenya flipped the switch on its latest geothermal expansion earlier this year, it did not just add capacity to its national grid. It crossed a symbolic threshold that no other African nation has reached: one gigawatt of installed geothermal electricity. In doing so, Nairobi planted a flag in the ground — and sparked a continent-wide conversation about who can follow, and how.

A Continent Alone at the Top

Kenya now stands alone in Africa with over 1,000 megawatts of geothermal capacity online, the vast majority of it clustered in the Olkaria fields of the Great Rift Valley. That makes Kenya the undisputed leader on a continent where geothermal potential is enormous but exploitation has been painfully slow.

The numbers are striking. According to the Geothermal Association of Kenya, the country has potential exceeding 10,000 megawatts — enough to power entire East Africa several times over. Only a fraction has been tapped. But that fraction is enough to make Kenya the world’s seventh-largest geothermal producer, running neck-and-neck with nations like New Zealand and Iceland that have built entire energy identities around the resource.

For the rest of Africa, the question is not whether geothermal makes sense — the geology practically screams that it does — but why so few countries have moved beyond pilot projects.

Why Africa Has Dragged Its Feet

The answer is rarely about resources. Countries like Ethiopia, Kenya’s neighbour to the north, sit on geological formations that rival anything in the Horn of Africa. Djibouti, Rwanda, and Uganda all have reported geothermal prospects. Tanzania’s hot springs have been catalogued for decades.

What these countries lack is the enabling ecosystem Kenya spent decades building: a national utility with deep technical expertise, a regulatory framework that attracts private capital, and a state-backed drilling programme that took on the upfront risk that private investors would not touch.

Kenya Electricity Generating Company (KenGen) and the Geothermal Development Company (GDC) were not accidental creations. They were deliberate institutional responses to a specific market failure — the gap between known resources and the capital needed to prove them.

The Lessons Other Nations Are Now Studying

Analysts at the African Energy Forum have been studying what they call the “Kenya model” — and the conclusions are becoming clear.

First, geothermal development requires patient, de-risked public capital. Kenya’s government spent decades absorbing the exploratory drilling costs that would scare off commercial lenders. That public money unlocked private investment once the resource was proven.

Second, domestic technical capacity is non-negotiable. Kenya’s geothermal programme trained generations of engineers, geologists, and technicians locally. That human capital now drives costs down and keeps expertise inside the country.

Third, policy must be stable and long-term. Kenya’s feed-in tariff for geothermal, introduced in the 2000s, gave private developers the revenue certainty they needed to commit capital. Several large independent power producers now operate Olkaria units alongside KenGen.

What Happens Next

Kenya’s next target is 2,000 megawatts by 2030. That would require continued investment in new well fields, upgraded transmission infrastructure, and smarter grid management to handle the intermittency challenges that come with a growing renewable portfolio.

But the bigger story is what happens beyond Kenya’s borders. With the African Union’s continental power masterplan calling for a tripling of electricity access by 2030, geothermal is increasingly framed not as Kenya’s advantage but as Africa’s opportunity.

Ethiopia is the most frequently cited candidate for a “second wave.” Its Rift Valley geology mirrors Kenya’s, and the state-owned Ethiopian Electric Power has begun exploratory drilling in the Aluto Langano field. But experts say Ethiopia needs at least another five years of sustained investment before it approaches the threshold Kenya crossed this year.

For the continent’s smaller nations — Rwanda, Burundi, Djibouti — the pathway may involve regional cooperation. A shared geothermal platform across the East African Community could distribute the enormous upfront costs across multiple national utilities, making projects bankable that no single country could finance alone.

The Global Context

Kenya’s geothermal milestone arrives at a moment when global energy planners are scrambling to find clean baseload alternatives to coal and gas. Unlike solar and wind, geothermal provides round-the-clock power without storage — a quality that makes it invaluable for industrialising economies.

The International Energy Agency estimates that Africa could host up to 15 gigawatts of geothermal capacity by 2050, but only if governments treat it as a strategic national resource rather than a niche experiment.

For now, Kenya is in a category of one. Whether others can catch up — and how quickly — may determine whether Africa’s clean energy transition is built on bedrock, or continues to search for solid ground.
