(Tamazunchale Combined Cycle Power Station (Mexico)

IDOM has developed the detailed engineering for a Combined Cycle Power Station located within the Tamazunchale municipality, in the Mexican state of San Luis de Potosí.  The power station has a net generation capacity of 1135 MW and consists of four GE 7FA gas turbo-generator units  and 2 GE D11S steam turbines. The layout of the station is in two modules that are each made up of two gas turbines and one steam turbine.

IDOM’s project responsibilities included all disciplines: civil design, mechanical and process piping, electric, and instrument and control activities. A relevant point of the project was the decision to use the most advanced design tools. They range from the PDS for the piping design (already proven on various projects), to the SmartPlant PID for the design of “intelligent” P&IDs (Piping and Instrument Diagrams), and including three-dimensional design programs for piping supports or applications for the development support of instrument design, as well as the usual calculation tools for metal structures, pipe flexibility or fluid network simulation.

The plant became fully operational in 2007.

Technical Due Diligence Evaluation,  Biodiesel Production and Cogeneration using Renewable Fuels

AEC Idom performed a technical due diligence evaluation of three cogeneration plants, two bulk fuel terminals, a biodiesel processing technology and two industrial sites for potential construction and development planning.  AEC Idom provided these third party evaluations in support of RPL’s initial public offering and admission to trading on AIM, a market operated by the London Stock Exchange. The evaluations were conducted in conjunction with Grant Thorton Corporate Finance, the Nominated Advisor, and Libertas Capital, the Broker to provide potential investors with an opinion as to whether the power plants, biodiesel manufacturing process, raw material logistics, and RPL’s plans for construction, alteration and operation were technically feasible and consistent with their financial projections. AEC Idom’s identification, assessment and review responsibilities include

• the overall system design, capabilities and operating costs
• the major equipment, life expectancy, and maintenance costs
• connection with offsite services and utilities
• the capability of each plant to achieve the project objectives
• modifications required to achieve the project objectives
• the relevant environmental factors involved in the project
• key risks and uncertainties associated with the project
• the project schedule.

(Hidrocantabrico Combined Cycle Power Station, Castejon 2 (Navarre, Spain)

IDOM’s engineers prepared the basic engineering and detailed design for this “1x1x1” single-shaft configured combined cycle power plant known as Castejon 2.  The engineering design was performed in 2006 and 2007. The plant has a nominal generation capacity of 400MW and consists of an Alstom KA-26-1 gas turbine, a three pressure level HRSG and a 150MW steam turbine also by Alstom.  Cooling is supplied through a recirculating tower loop with make-up water provide by the adjacent river. The plant became fully operational in 2007.
