Lesotho’s Mountain Gamble: A $6.2 Billion Bet on Hydropower and AI

Lesotho is not a name that typically appears in conversations about the global artificial intelligence race. A landlocked mountain kingdom of roughly 2.3 million people, entirely surrounded by South Africa, with an economy smaller than many mid-sized cities — it is an unlikely candidate for a headline-grabbing tech infrastructure deal. And yet that is precisely what has happened.
The Lesotho government has signed a binding $6.2 billion agreement with US-based Convalt Energy to build the Kobong Hydropower and AI Data Centre Project, a combined development near the Kobong Dam in the mountainous Mokhotlong district. The plan calls for at least 1,200 megawatts of renewable hydropower, alongside up to 4.6 gigawatts of solar generation and 4 gigawatt-hours of battery storage, all feeding a green-powered data centre designed to serve regional and international digital demand. To put the scale in perspective: the investment is worth nearly three times Lesotho’s entire annual GDP, and it would represent more than a sixteen-fold increase over the country’s current electricity generation capacity, which currently relies heavily on imports from South Africa’s Eskom.
Why should business leaders elsewhere on the continent pay attention to a project in one of Africa’s smallest economies? Because it captures, in one deal, two of the defining forces reshaping global infrastructure investment: the insatiable appetite for AI computing power, and the recognition that reliable, low-carbon electricity is now the binding constraint on where that computing power gets built. Data centre developers worldwide have run into the same wall — plenty of demand for AI infrastructure, not enough clean power to run it. Lesotho’s pitch is to solve both problems at once, pairing dedicated hydropower generation directly with the facility it powers, an integrated model that sidesteps the grid bottlenecks that have delayed similar projects elsewhere.
There is also a quieter geopolitical story here. Convalt’s arrival marks a notable return of American private capital into African infrastructure, a sector where Chinese state-backed firms have dominated for years under Belt and Road-style financing. The US Embassy in Lesotho has framed the deal as one that will generate substantial American manufacturing exports alongside local jobs, clean energy, and economic development — a rare instance of Washington and a small African state finding mutual commercial interest at this scale.
Government officials in Maseru have been careful to temper expectations. This is a binding memorandum of understanding, not a final construction commitment, and feasibility studies, environmental assessments, and financing arrangements all still need to be completed before ground is broken, with construction not expected to begin until 2029. Convalt itself is a relatively young company whose largest completed project to date is a modest 8-megawatt facility in India, a gap between ambition and track record that serious investors will be watching closely.
But even accounting for that healthy scepticism, the signal is hard to ignore. If even a fraction of this project materialises, Lesotho could shift from being a net importer of electricity to a regional power exporter and a genuine node in Africa’s digital economy — proof that scale of opportunity, not size of country, is what increasingly attracts the world’s biggest infrastructure bets.
