Mainstream Energy Solutions Limited (MESL), operator of the 760 megawatts (MW) Kainji hydropower plant and the 578MW Jebba hydro, has begun an $89 million (about N37.2 billion) project to add two new turbines of 220MW capacity to the Kainji plant.

At least 10 firms in Europe and the United States are developing variations of this kind of kite power. If they succeed, kites could make it possible to build wind farms on land that isn’t windy enough for conventional wind turbine towers. Kites might also be a better choice for offshore wind power, and one day could even replace at least some anchored towers now in use.
