Electricity from a planned coal-fired plant in Lamu, Kenya might cost ten times as much as its developers suggest, according to an energy group that wants the project canceled. The plant, which will require an estimated $2-billion investment, is projected to be able to produce 1 050 MW of electricity. The project is 51% owned by Nairobi-based Centum Investment, and is backed by General Electric’s so-called Ultra-Supercritical Clean Coal Technology.
