Lesotho has signed a binding agreement with US-based Convalt Energy worth $6.2 billion.
The deal covers a 1,200-megawatt hydropower facility and an integrated AI data centre.
It was formally signed on 4 June 2026 between Convalt Energy and Lesotho’s Ministry of Energy.
The agreement is the largest foreign direct investment in Lesotho’s recorded history. The project is known as Project Kobong.
What Is Project Kobong?
Project Kobong is named after the Kobong Dam. The dam sits in the mountainous Mokhotlong region in Lesotho’s northeast.
The project pairs two of the most consequential infrastructure assets of our time.
One is large-scale renewable energy generation. The other is next-generation AI computing infrastructure.
Convalt Energy plans to develop at least 1,200 megawatts of hydropower capacity.
This will be paired with an integrated artificial intelligence data centre.
The data centre will run entirely on the clean energy produced on site.
The wider partnership could also see the development of approximately 4.6 gigawatts of solar generation capacity.
This includes ground-mounted and floating solar installations.
The plan also includes up to 4 gigawatt-hours of battery energy storage systems.
The scale of this ambition is significant. The $6.2 billion total is equivalent to 98 billion Lesotho maloti.
That figure represents nearly three times Lesotho’s gross domestic product of $2.27 billion recorded in 2024.
Why Lesotho? Why Now?
The location is not accidental. Lesotho has long been a source of clean water for the region.
Through the Lesotho Highlands Water Project, Lesotho supplies an estimated 60% of Johannesburg’s water requirements.
At the same time, it imports electricity from South Africa. That paradox has defined the country’s economic position for decades.
In 2024, Lesotho imported 438 gigawatt-hours out of total national electricity consumption of 970 gigawatt-hours.
This came primarily from South Africa’s Eskom and Mozambique’s Electricidade de Moçambique.
The Kobong project is designed to reverse that dependency entirely.
The project is designed to strengthen Lesotho’s energy security.
It aims to reduce reliance on imported electricity. Officials say it could position the country as a regional exporter of power.
There is also a global dimension driving this investment.
The strategic pairing of clean energy and computing power is increasingly significant in the AI era.
Data centres dedicated to AI are highly energy-intensive. Electricity availability has emerged as one of the main constraints on hyperscale data centre development worldwide.
Lesotho’s mountains and rivers offer a natural solution to exactly that constraint.
The Diplomatic Groundwork
The announcement followed a meeting between King Letsie III and former U.S. House Majority Leader and Convalt Energy board member Richard Gephardt.
Discussions focused on advancing plans for the large-scale infrastructure initiative known as Project Kobong.
The project was officially launched during a ceremony hosted by the U.S. Embassy in Maseru on 31 July 2026. Senior government officials, diplomats and business leaders attended.
U.S. Chargé d’Affaires Thomas Hines described the investment as reflecting a new phase in U.S.-Lesotho relations.
He framed it as centred on commercial partnerships rather than traditional development assistance, calling the initiative “trade over aid.”
Convalt Energy CEO Hari Achuthan said the project is expected to create jobs, develop local skills and stimulate long-term economic growth through large-scale infrastructure development.
Who Is Convalt Energy?
Convalt Energy is a U.S.-based company working across renewable energy development and data centre construction.
CEO Hari Achuthan said Convalt has repositioned its operations toward providing integrated infrastructure solutions for AI-driven and energy-intensive industries.
The Kobong project reflects that strategic direction precisely.
The company’s combined focus on energy generation and digital infrastructure makes it a distinctive player.
Most energy developers and data centre operators are separate businesses.

Convalt is building both as one integrated system. That integration is central to why the Kobong model works.
What the Project Would Deliver
The benefits, if the project proceeds to completion, would be felt at multiple levels.
At the national level, Lesotho moves from importing nearly half its electricity to becoming a net regional exporter.
That shift changes the country’s fiscal position and reduces its vulnerability to pricing decisions made in Pretoria or Maputo.
At the regional level, a new source of 1,200 megawatts of clean power enters the Southern African Power Pool.
This is meaningful additional capacity for a region that has faced persistent electricity shortfalls.
At the continental level, Lesotho would become home to one of Africa’s most significant AI data centre developments.
Officials pointed to the country’s renewable energy potential as a competitive advantage as nations compete to host infrastructure for next-generation AI and digital services.
For jobs and economic development, the Lesotho government’s spokesman Boitelo Rabele confirmed the project is expected to create jobs and support local business development.
What Still Needs to Happen
Honesty about the road ahead matters here. The project remains subject to feasibility studies, financing, permitting, regulatory approvals and definitive agreements.
A binding Memorandum of Agreement is a significant milestone. It is not, however, the same as a shovel in the ground.
Large infrastructure projects at this scale routinely take years to move from agreement to construction.
Financing arrangements for $6.2 billion must be structured and secured. Environmental and community impact assessments must be completed.
Grid interconnection agreements with neighbouring countries must be negotiated.
None of these are insurmountable. But the gap between announcement and delivery is where many ambitious African infrastructure projects have historically stalled.
The degree of diplomatic and U.S. government engagement in this project is a credible signal that Kobong is being treated seriously at the highest levels.
The Bigger Picture
Lesotho has always possessed natural assets of enormous regional value. Its highlands feed rivers. Its rivers generate water.
Its mountains can now generate power and, through that power, computing capacity for an AI-driven world.
The project’s integrated energy-and-data-centre model is particularly significant because electricity availability has emerged as one of the main constraints on hyperscale data centre development worldwide.
Lesotho, a landlocked country of just 2.3 million people, is positioning itself to solve a global problem with local geography.
If Project Kobong is built as agreed, it will not just be the largest investment in Lesotho’s history.
It will be a case study in how small African nations can leverage natural resources to compete in the global digital economy.
