Duro Felguera and Elecnor to build 790 MW combined cycle power plant in Mexico

Duro Felguera (DF), in a 50/50 consortium with Elecnor, has won the tender called by the Comisión Federal de Electricidad (the Federal Electricity Commission or CFE in Spanish) in Mexico to build the Empalme II combined cycle power plant in the State of Sonora. The project is for 397 million dollars, equivalent to 349.3 million Euros. The deadline for delivery is estimated at 30 months.

According to the contract terms, signed at the close of business on Friday 23 October in Mexico City, the capacity of the Empalme II plant will be roughly 790 MW, and it will be gas-fired. There will be two gas turbogenerator units, two heat recovery boilers with three pressure levels and a steam turbine. The cooling system will be simple and will employ seawater. The plant will be connected to a 400 kW substation.

According to CFE, the purpose of the facility is to meet the growing demand for electricity in the north-west of the country.

Mexico is the country where DF has delivered most projects in Latin America, mainly in the field of energy. The power installed is almost 4,500 MW. Since 1998 the company has collaborated in the delivery of combined cycle, open cycle and cogeneration power plants with technologists such as Westinghouse, Siemens and Alstom Power.

DF’s first steps in Mexico in the field of energy were taken in 1998 in projects that the group had contracted by means of its subsidiaries Felguera Montajes y Mantenimiento and Mompresa, for the installation of turbomachinery. Both companies had previous experience in Colombia and started work in Mexico with the electromechanical assembly at the 150MW open cycle power plants of El Sauz, Hermosillo and Huinalá.

These projects were delivered to Westinghouse and followed by the full electromechanical assembly of recovery boilers at the combined cycle plants of Monterrey I, II and III, and Hermosillo, and for the full electromechanical assembly of the Rosarito plant, this time for the multinational ABB Alstom Power, and in larger facilities. In the first decade of the 21st century, the company was contracted by Siemens-Westinghouse to deliver the majority of the work at the open cycle plants of El Sauz II and El Encino: preparing the land, civil works, supplying the balance of plant equipment, the complete electromechanical assembly and commissioning.

These experiences enabled DF to keep on working in the country, with practically the whole assembly of the power plants of Valle de México, Naco Nogales, San Lorenzo and Tuxpan, in some cases almost 350 MW. In addition to the work on all these gas-fired power plants, in 2003 and 2004 the company delivered an EPC turnkey project for a cogeneration plant within the Pemex petrochemical Pajaritos plant, located in Veracruz. In this case DF took on the whole project, from the engineering to commissioning: 39 MW and 180 tons of steam per hour. Almost ten years later, Mompresa built further cogeneration plants in Mexico: one for the paper manufacturer Biopappel in Veracruz, and another for the textile company Kaltex Fibers in Altamira.

Apart from the energy field, DF has also worked on projects on Mexico for the petrochemical, iron and steel, cement and bulk handling sectors, for clients as important as Pemex, Cemex and Altos Hornos de México.
