Tokyo, September 29, 2008 - Mitsubishi Heavy Industries, Ltd. (MHI) has received a full-turnkey order for two sets of LNG-fired gas turbine combined-cycle (GTCC) power generation systems, some 800 megawatts (MW) in total, from Endesa Generacion S.A., an electricity generation company in Spain. The new systems are slated to go on-stream in 2011.
Endesa Generacion S.A. is a power generation arm of the Spanish utility Endesa S.A. Including the 400 MW Cristobal Colon GTCC power plant which went on-stream in 2006, to date MHI has delivered many turbines to Endesa for power generation – 5,000 MW in total, equal to approximately 20% of the utility’s domestic power generation capacity.
MHI received its first order for equipment for the Compostilla power station – the 330 MW No.3 unit – in 1968, an event that also marked the first large-size steam turbine order placed to MHI from Spain. Later an order was received for steam turbines for the No.4 and 5 units, 350 MW each. Endesa's Compostilla power station is thus very meaningful for MHI as the power plant marked the beginning of the company’s power generation equipment business in Spain – and in Europe. Subsequently MHI also delivered flue-gas desulfurization systems for the No.4 and 5 coal-fired power generation units at Compostilla, and has further strengthened its relationship with Endesa. MHI believes Endesa's high evaluation of its delivery and operational track record for these turbines and systems, as well as the performance of its most advanced GTCC systems and dependability of its after-sales services, led to the latest order.
With GTCC type power generation, gas and steam turbines are used in combination to generate electricity in two stages, utilizing high-temperature exhaust gas from the gas turbine. This configuration enables GTCC power plants to achieve higher thermal efficiency than non-GTCC plants such as conventional boiler steam turbine plants. Higher efficiency means that GTCC plants reduce fuel consumption relative to electricity output and emit less CO2, thus making them friendlier to the environment.
MHI has delivered many GTCC power generation systems in Japan and abroad, and in the process has gained widespread trust in the market for its proprietary technologies and prompt delivery record. On the strength of the latest order, going forward MHI intends to aggressively conduct marketing activities for its LNG-fired GTCC power generation systems, which contribute to both effective utilization of energy and reduction in environmental loads.
