Lesotho Launches Phase II of Ramarothole Solar Power Project to Expand Renewable Energy Capacity

Lesotho has taken another significant step toward strengthening its energy sector with the launch of Phase II of the Ramarothole Solar Power Project in Mafeteng. On July 10, 2026, the Ministry of Energy and Mining, through the Lesotho Electricity Generation Company, officially launched the next phase of the country’s flagship solar energy development. The expansion demonstrates the government’s continued commitment to increasing electricity generation through clean and sustainable energy sources. As demand for electricity continues to grow across homes, businesses and industries, renewable energy projects have become increasingly important in supporting economic growth and reducing dependence on imported power. The launch of Phase II represents a major milestone in Lesotho’s long-term energy strategy and highlights the country’s determination to build a more secure and environmentally responsible electricity supply.

The new phase of the Ramarothole Solar Power Project will add 50 megawatts of renewable electricity generation capacity to the existing 30 megawatts already produced during Phase I. This expansion will increase the total capacity of the Ramarothole Solar Plant to 80 megawatts, making it one of Lesotho’s most important renewable energy facilities. Increasing domestic electricity generation is expected to improve the country’s ability to meet rising energy demand while reducing reliance on electricity imports from neighboring countries. Producing more electricity locally also strengthens national energy independence and creates greater stability within the country’s power system. The expanded capacity will support households, commercial enterprises and public institutions with a more reliable electricity supply that contributes to long-term national development.

One of the most notable features of Phase II is the inclusion of an 8 megawatt Battery Energy Storage System, which will significantly improve the efficiency and reliability of the solar power facility. Solar energy naturally depends on sunlight, meaning electricity production decreases after sunset or during periods of poor weather. The battery storage system addresses this challenge by storing excess electricity generated during the day so that it can be supplied to the national grid during the evening or whenever demand remains high after solar production has stopped. This technology allows renewable energy to become a more dependable source of electricity throughout the day and night. The addition of battery storage strengthens energy security while ensuring that the benefits of solar power extend beyond daylight hours.

The expansion of the Ramarothole Solar Power Project is expected to generate several long-term economic and environmental benefits for Lesotho. Greater investment in renewable energy helps reduce greenhouse gas emissions while supporting global efforts to combat climate change. Solar power also decreases dependence on fossil fuels, contributing to cleaner air and a healthier environment for future generations. During construction and ongoing operations, projects of this scale often create employment opportunities for engineers, technicians, construction workers and support staff, while also encouraging skills development within the renewable energy sector. Reliable electricity further supports business growth, agricultural productivity, healthcare services, education and digital infrastructure, all of which depend on a stable power supply.

The project also aligns with broader national goals of improving energy access and promoting sustainable development throughout Lesotho. As electricity demand continues to increase due to population growth, urban development and industrial expansion, investments in renewable infrastructure become increasingly important for maintaining a stable energy system. Solar energy offers a practical solution because Lesotho enjoys abundant sunshine throughout much of the year, making solar generation both efficient and environmentally friendly. By investing in local electricity production, the country strengthens its resilience against fluctuations in imported electricity supplies and international energy prices. The Ramarothole Solar Power Project demonstrates how strategic investments in clean energy can contribute to long-term economic resilience while supporting national development priorities.

The launch of Phase II of the Ramarothole Solar Power Project marks another important chapter in Lesotho’s transition toward a more sustainable and secure energy future. Increasing the plant’s total capacity from 30 megawatts to 80 megawatts, together with the installation of an 8 megawatt Battery Energy Storage System, represents a significant investment in modern energy infrastructure. The project will improve electricity reliability by allowing power generated during the day to be stored and supplied at night, strengthening the country’s overall energy security. As Lesotho continues expanding its renewable energy portfolio, initiatives such as the Ramarothole Solar Power Project will play a vital role in supporting economic growth, environmental sustainability and improved quality of life for communities across the country. The successful implementation of this expansion reinforces the government’s commitment to building a cleaner, more reliable and self-sufficient energy sector that will benefit the nation for many years to come.
