Swaziland is a small state between South Africa and Mozambique. The country has a low electrification rate of around 27%, one of the lowest in the region, but is a part of the Southern African Power Pool. The main utility is the Swaziland Electricity Company, a government owned utility that controls transmission, distribution, and supply of power. The utility’s installed generating capacity is small compared to the level of demand, and it relies on imports for between 80% and 90% of all the power it sells. There are, in addition, a number or sugar companies that generate power for themselves, using sugar cane waste and imported coal. The county has reserves of high quality coal and hydropower, biomass, solar, and wind potential, but the small size of the country, coupled with its limited financial resources, makes developing any of these energy sources difficult - without external assistance. The country’s best hope for generating capacity expansion is to exploit its coal reserves with the help of partners, in order to export power to South Africa, and other neighbouring countries.
