Many developing countries lack reliable power infrastructures. That's been a boon for USP&E Global, a $43.8 million company in Celina, Texas, that builds power stations in dozens of developing nations. The station shown here runs on heavy fuel oil and powers London Mining's iron-ore operations in Marampa, Sierra Leone. Thirty-six of the station's 50 employees are locals, including technicians Alimamy Conteh (pictured at left) and Abdul Rahman Sankoh (right). USP&E is developing an internship program for orphans in Sierra Leone. "We provide long-term jobs and, sometimes, careers for these people," says Will Gruver, who founded USP&E in 2002. "We're making a difference, and it's really exciting."
