Two years ago, Kenyan President William Ruto came back from a trip to Washington with one of the biggest tech announcements East Africa had seen in years. Microsoft and the UAE based AI company G42 had agreed to invest a billion dollars in a geothermal powered data center about 100 kilometres northwest of Nairobi. Brad Smith, Microsoft's vice chair and president, called it the single largest and broadest digital investment in Kenya's history. President Ruto called it bigger than technology itself, a partnership between three countries built around a shared vision of a digitally empowered nation.

The plan was genuinely ambitious. G42 would lead construction, working with local partner EcoCloud, building a facility powered entirely by geothermal energy at the KenGen Green Energy Park in Olkaria, the same site where Kenya already generates much of its renewable power. The first phase would carry 100 megawatts of capacity, with room to scale up to a full gigawatt over time. Microsoft would run Azure out of the site, creating an entirely new East African cloud region, the kind of infrastructure that lets businesses across Kenya and the wider region host data and run AI workloads without routing everything through servers in Europe or the Gulf. On top of the data center itself, the two companies promised a Nairobi based innovation lab, support for a local language AI model, and digital skills training for the region.

For a country trying to position itself as East Africa's tech hub, this was the kind of deal that could change the conversation entirely. Kenya already had ambitions in this direction, having signed an earlier 600 million dollar deal for a separate geothermal powered data center at the same Olkaria site. The Microsoft and G42 announcement layered a much bigger, more globally significant project on top of that foundation.

Two years later, the project has hit a wall. According to reporting from Bloomberg, talks between Microsoft, G42, and the Kenyan government broke down over a single sticking point, what is known in the industry as offtake. Microsoft wanted the Kenyan government to guarantee that public bodies would buy a defined amount of computing capacity from the facility every year. It is a fairly standard ask for a project this size, since data centers are expensive to build and operators want certainty that someone will actually pay to use the capacity once it is running. Nairobi was not able, or willing, to commit at the level Microsoft was asking for.

There is more beneath the surface than just a contract dispute. Some reporting suggests Kenya's national electricity grid itself may not be able to comfortably support a facility of this scale once it scales toward its full gigawatt ambition, even with geothermal power in the mix. Power reliability has been a long running challenge for Kenyan infrastructure, and a billion dollar data center is not the kind of project you want running into capacity surprises after the cement has been poured.

It is worth being clear about what this stall does and does not mean. The project has not been cancelled. No party has walked away from the table for good. What has happened is that two years after a triumphant announcement in Washington, the deal remains stuck in the same place many ambitious infrastructure partnerships get stuck, the unglamorous negotiation over who guarantees what, and for how long, and at what cost if things do not go to plan.

This matters beyond Kenya. The Microsoft and G42 deal was always bigger than one data center. It was part of a broader push by the United States to plant American cloud infrastructure across Africa before Chinese providers could lock up the market, and a test case for whether African governments can strike these mega deals on terms that work for both sides. If a deal this high profile, with this much political backing, can stall over offtake guarantees, it tells other governments across the continent exactly what to expect, and exactly what to negotiate harder on, the next time a global tech giant comes calling with a billion dollar pitch.
