Alstom has signed a turnkey geothermal power plant contract with Mexico’s Comisión Federal de Electricidad (CFE) in the Puebla state of Mexico. The contract for the 25 MW Los Humeros II Phase B plant follows the Los Humeros II Phase A power plant contract signed by Alstom in May 2009. When completed in May 2012, the Los Humeros II plants will produce more than 400 GWh of reliable, cost-effective and clean electricity, enough to power 100 000 homes in Mexico’s eastern Puebla state.

Under the terms of the contract, Alstom will supply the complete engineering, procurement and construction (EPC) solution including the steam turbine, air cooled turbogenerator, turbine control and distributed control system (this project will use Alstom’s ALSPA Series 6). The turbine will be produced at Alstom’s local manufacturing facility in the municipality of Morelia, Michoacan state.

Mexico is the fourth largest geothermal energy producer worldwide after the USA, the Philippines and Indonesia. This project is Alstom’s second since its recent return to the fast-growing geothermal market. In the past, CFE contracted Alstom for several geothermal contracts including the building of four 25 MW units at the Los Azufres geothermal power plant in Michoacan state in 2000, and the supply of two 5 MW units to the Las Tres Virgenes geothermal power plant in Baja California Sur in 1998.

Over the last 20 years, CFE has contracted Alstom to build, retrofit and service power generation plants and equipment spanning a wide variety of thermal and renewable energy sources including fossil-fired (fuel-oil, coal, gas), hydropower and geothermal capacity. Since 1988, Alstom has installed 10 000 MW in Mexico, providing 20% of CFE’s power generation capacity.
