Edwaleni Solar Power Station, is a 100 megawatts power plant under construction in . The solar farm is under development by Frazium Energy, a subsidiary of the Frazer Solar Group, an Australian-German conglomerate. The solar component is complemented by a , expected to be the largest in Africa. The energy off-taker is Eswatini Electricity Company (EEC), the national electricity utility company, under a 40-year [pdf]
Although Eswatini's electrification rates are relatively high, they are still a long way off 100% (the country's target for 2022). Solar power is the most viable solution for Eswatini to help meet its electrification goals and save costs down the line.
Formerly known as Swaziland, the Kingdom of Eswatini issued its first utility-scale solar tender in June. It aims to increase the share of renewables in the country’s electricity mix to 50% by 2030.
The biggest driver of growth in Eswatini’s PV market is private PV projects. In 2022, Eswatini partnered with Frazium Energy to commission a new 100MW solar storage project with 75,000 PV panels, hoping to produce more than 100 million kWh of electricity a year and generate at least 200 jobs.
Despite being one of Africa’s smallest countries, Eswatini has an impressive, diverse topography and climate. Unfortunately, its electricity infrastructure is not reliable.
The biggest driver of growth in Eswatini's PV market comes from private PV projects. In hopes of reaching ambitious goals, Eswatini has made solar panels and batteries exempt from import duties to help with this.
The Eswatini Energy Regulatory Authority (ESERA) has begun the process of procuring new generating capacity from independent power producers, with the support of Eswatini’s Ministry of Natural Resources and Energy (MNRE).

The first were installed in 2009, and are not associated with storage. The installed capacity is 13 MW, in particular via the Longoni power plant, inaugurated in 2010. Solar energy is the only renewable energy with significant development potential on the island; the wind potential (22 MW according to a study) would not lead to a significant production because the wind blows only 6 months per year.

Quaise, Inc was founded in 2018 to develop a drilling system for converting existing power stations to use superdeep . The system would repurpose existing technology to drill 20 kilometers beneath the surface, where temperatures exceed 400°C. No fracking would be required, avoiding the potential for in other geothermal systems. Drilling using this technique is hoped to be fast, with boreholes aime. [pdf]
