In addition to its power generation facilities, DEI has an equity investment in National Methanol Company, a Saudi Arabian regional producer of methanol and methyl tertiary butyl ether (MTBE), a gasoline additive.
Duke Energy Corporation began investing in Latin America in 1998. DEI offers safe, reliable, high-quality power generation services to the communities it serves.
