Lesotho has signed what it describes as the largest investment commitment in the country's history, agreeing a $6.2bn deal with US renewable energy developer Convalt Energy to develop a 1,200MW hydropower project and an artificial intelligence (AI) data centre near the Kobong Dam

The agreement, signed on June 6, is valued at almost three times Lesotho's estimated $2.27bn GDP, underlining the transformative potential of the project if it reaches completion. Government officials said the development could eventually turn the mountainous kingdom from a net electricity importer into a regional exporter of renewable electricity, TechCabal reports.

The project would represent a dramatic shift for a country whose entire installed generation capacity currently stands at just 72MW, all sourced from renewable energy. The Muela hydropower station, developed under the Lesotho Highlands Water Project, supplies more than half of domestic electricity demand. However, Lesotho still imports more than 50% of its power requirements from South Africa's Eskom Holdings and Mozambique's Electricidade de Moçambique through the Southern African Power Pool during periods of peak demand.

A 1,200MW hydropower facility would increase Lesotho's installed generation capacity by more than sixteen-fold, potentially enabling the country not only to achieve energy self-sufficiency but also to become a significant exporter of renewable electricity to neighbouring countries.

The inclusion of an AI-focused data centre reflects a growing global trend of co-locating energy-intensive digital infrastructure with abundant renewable power. AI computing and cloud services require vast quantities of reliable electricity, prompting developers worldwide to seek locations with access to low-cost green energy and stable power supplies.

Lesotho has increasingly sought to position itself as a renewable energy destination. The I-TRACK Foundation recently approved the country for participation in the International Renewable Energy Certificate for Electricity (I-REC(E)) system, allowing renewable electricity generated in Lesotho to be certified and traded through internationally recognised renewable energy certificates. The country's Ministry of Energy supported the initiative as part of broader efforts to attract investment into renewable energy projects and expand electricity access.

The government is also advancing the Lesotho Renewable Energy and Energy Access Project (LREEAP), which aims to expand renewable-energy-based electrification in rural and peri-urban communities while supporting industrial development and economic growth. Officials see renewable energy as a potential catalyst for industrialisation in a country whose economy has historically depended on water exports, textiles, remittances and customs revenues from the Southern African Customs Union.

Despite the scale of the announcement, the project remains at an early stage. What has been signed is a binding memorandum of agreement that establishes a framework for cooperation rather than a final engineering, procurement and construction contract. Feasibility studies, environmental assessments, financing arrangements, regulatory approvals and commercial offtake agreements will still need to be completed before construction can begin.

Convalt Energy, a privately held US company founded in 2011, has increasingly focused on solar manufacturing and renewable energy projects in the United States in recent years. While the company has announced large energy investments in several international markets, it has not previously completed a project on the scale of the proposed Lesotho development.

The project's success will ultimately depend on securing long-term, creditworthy power purchase agreements, attracting a financing consortium capable of supporting a multibillion-dollar investment and demonstrating commercial demand for a large-scale AI data centre in a country that currently lacks an established digital infrastructure ecosystem.

If realised, the development would allow Lesotho to capture significantly greater value from the water resources it has long supplied to South Africa through the Lesotho Highlands Water Project. For now, however, the agreement represents an ambitious vision whose viability will depend on whether feasibility studies, financing plans and commercial arrangements can withstand independent scrutiny.
