The Termoeléctrica del Golfo (TEG) Project, financed by the Inter-American Development Bank’s (IDB) Private Sector Department, consists of the construction, operation, and maintenance of a 230-MW Circulating Fluidized Bed (CFB) petroleum coke-fired power plant site in the Tamuín area of the Mexican state of San Luis Potosí. IDB documents assert the project is designed principally to generate electricity for thirteen cement plants located in the central and northern regions of Mexico; local residents challenge that assertion and claim that the energy generated will be consumed by the CEMEX (Cementos Mexicanos, S.A.) cement plant which is adjacent to the TEG plant.
