GE Turbines To Power Capacity Expansion

Posted on October 21, 2009

GE Energy’s gas turbine technology has been selected by South Mississippi Electric Power Association (SMEPA) to expand the capacity of its Moselle Generating Station near Hattiesburg, Mississippi, U.S.A. The project will add 150 MW of output, helping SMEPA meet the growing requirements of its cooperative members. South Mississippi Electric, a generation and transmission cooperative, has been in business for more than 40 years and today provides wholesale electric power for more than 400,000 homes and businesses served by 11 member systems.

GE will supply two Frame 7EA gas turbines, technical advisory services and customer training for the Moselle project. With 780 units in service, the GE 7E/7EA gas turbine fleet has accumulated millions of hours of service. “South Mississippi Electric sees a need to increase its supply of reliable, efficient power to meet the requirements of its member cooperatives,” said John Reinker, general manager of heavy duty and combined-cycle gas turbines for GE Energy. “With a proven track record spanning millions of hours of commercial service, GE 7EA gas turbines offer a reliable and efficient solution for meeting those growing energy needs.”

GE’s 7EA gas turbines are workhorses of the industry and have been used in a wide variety of power generation, industrial and cogeneration applications. The new machines for SMEPA will be installed behind boilers that currently provide steam for units 1 and 2 at the Moselle site. They will be equipped with GE’s dry low NOx combustion technology, restricting NOx emissions to 9 parts per million to help SMEPA meet the latest emissions standards. When the new gas turbines are coupled with the existing steam turbines at the site, each of the new combined-cycle units will generate 134 MW and will be 30% more efficient than the existing Unit 1 and Unit 2 steam units. It is expected that both of the new GE units will be commissioned by the spring of 2012.
