Subsidiaries of Spain-based Abengoa and GE Energy Financial Services, a unit of GE, will invest US$180 million to develop the largest cogeneration power plant in Mexico. The 300-megawatt gas-fired facility with a total project cost of US$640 million will be located at the Nuevo Pemex gas processing complex, owned by Pemex Gas y Petroquimica Basica, a subsidiary of Mexican state oil company Pemex. Located near Villahermosa, Tabasco, the plant will supply Nuevo Pemex with power and steam under a 20-year services agreement.

Powered by cleaner burning natural gas, the facility will help the Mexican government meet its commitment to reduce greenhouse gas emissions by 50 percent below 2002 levels by the year 2050. To help meet these objectives, the government is promoting combined heat and power, or cogeneration, as an energy efficient option.

The Abengoa subsidiaries-Abener Energia and Abengoa Mexico, companies of Abeinsa, the Engineering and Industrial Construction Business Group of Abengoa-and GE Energy Financial Services will own the project. Abener Energia and Abengoa Mexico will invest US$108 million and the GE unit will invest US$72 million.

A group of lenders including Banobras, Santander, Scotiabank, La Caixa, Banco Espirito Santo, Credit Agricole, Export Development Canada and HSBC is providing US$460 million in debt for the project. Construction began in September 2009, with commercial operation expected in 2012.

The plant is expected to directly supply 55 percent of Nuevo Pemex's steam demand and all of its power demand; additional power output will be provided to other Pemex operations throughout Mexico over its national transmission system.

The Nuevo Pemex complex processes gas from on- and off-shore Mexican gas fields. As agreed in a separate transaction between GE Energy and Abengoa announced Jan. 26, the cogeneration facility will use two GE Energy Frame 7FA gas turbines. GE's F-Technology gas turbines have accumulated over 30 million combined operating hours around the globe. In addition, GE Energy signed a 20-year agreement to provide plant services, a key GE growth area.

"This transaction draws on our core strengths in structuring investments in long-lived, critical energy assets and expands our relationship with Abengoa," said Alex Urquhart, president and CEO of GE Energy Financial Services.

"As Pemex's first cogeneration plant under its development initiative, this facility will benefit from Abengoa's and GE Energy Financial Services' energy expertise and could serve as a model for other Pemex facilities," said Alfonso Gonzalez, chairman of Abeinsa.

Cogeneration, the simultaneous production of electricity and heat using a single fuel source such as natural gas, harnesses heat that would otherwise be wasted. This can result in higher thermal efficiency or higher heat values; also, carbon dioxide emissions can be substantially reduced.
