Natural Gas Prieces and Ti ght Supply Openi ng the Door for IGCC Power By Victor de Biasi Project engineers and developers are applying current JGCC technology to plan and design 'clean' plants that will be more economic to own and operate than coal-fired steam and gasfired combined cycle plants.

Examples: * Negishi Plant. Nominal 340 MW IGCC planı in Japan, powered by a Mitsubishi M701 F gas turbine, is averaging %93 power availability and % 77.9 syngas availability. • Hatfield Plant. Engineering, procurement and construction cost tor one of two identical 430 MW IGCC modules, each powered by a Fr 9Fa turbine, is estimated at US 540 $ million. * Technology. Development of wanter quench cooler and desaturator gasification systems lor new IGCC planı designs offers thermal efficiencies up around %42 (LHV).
