Tokyo, February 4, 2008 - Mitsubishi Heavy Industries, Ltd. (MHI) has received a full-turnkey order from Nuon N.V. - a major Dutch energy company for three trains of natural gas-fired gas turbine combined-cycle systems (GTCC), over 430 MW (megawatts) each, for the approximately 1,300 MW Nuon Magnum Plant. The order marks Nuon's second GTCC plant to MHI following the IJmond blast furnace gas-fired combined cycle system delivered in 1997. The plant will go on-stream in 2011.

Nuon Magnum will be built in Eemshaven in the province of Groningen, at the northern part of Netherlands. Nuon plans future conversion of the plant to an integrated gasification combined-cycle (IGCC) power plant, adopting gasification technology of coal and biomass.

Each train will consist of a state-of-the-art M701F4 gas turbine, steam turbine, generator, heat recovery steam generator (HRSG) and other components (balance of plant: BOP). MHI will manufacture the gas and steam turbines, as well as procuring HRSG and BOP, and undertaking civil work, installation and commissioning. Mitsubishi Electric Corporation will manufacture the generators, and Mitsubishi Corporation will cooperate for the trade particulars.

Nuon is the Netherlands' leading energy company. Equity in Nuon is held by local and regional authorities. The company produces and delivers electricity, gas, heating and cooling to customers in the Netherlands, Belgium and Germany. Nuon owns more than 4,000 MW facilities, to which MHI has contributed with the IJmond plant in Velsen.

With GTCC system, 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 plants to achieve higher thermal efficiency than the other fossil power plants such as conventional boiler turbine plants. Higher efficiency saves fuel consumption and emits less CO2, thus more environmentally friendly.

MHI has delivered a large number of GTCC power systems both in domestic and overseas markets, and in the process has gained widespread trust in the market for its own technologies and prompt delivery record. Spurred by the latest order, going forward MHI intends to aggressively market its power generation systems that contribute to efficient energy usage and environmental burden reduction.
