High Efficiency Gas Turbines Overcome Cogeneration Project Feasibility Hurdles

Cogeneration project feasibility sometimes fails during early planning stages due to an electrical cycle efficiency which could be improved through the use of aeroderivative gas turbine engines. The aeroderivative engine offers greater degrees of freedom in terms of power augmentation through steam injection, NOx control without selective catalytic reduction, (SCR), reduced down time during maintenance and dispatchability. Other factors influencing enhanced aeroderivative economics are complete generator set packaging at the factory and full string testing before the delivery. A wide variety of hosts, including institutions, utilities, municipalities and industrial factories are observing that their cogeneration projects move faster by implementing aeroderivative gas turbine generation packages
