Solar projects worth $2.2 billion (£1.4bn) are to be built in Kenya.
Energy company SkyPower, which is investing the cash, will develop and build the projects in four phases across the country over the next five years.
They will have a total capacity of 1GW and more than 25,000 jobs are expected to be created.
The agreement was signed between the company and the Kenyan Ministry of Energy and Petroleum.
Cabinet Secretary Henry Rotich said: “Sustainable electrification is a central policy issue in Kenya and we are committed to making this a reality for our citizens while accelerating economic growth in the process.”
