GE Energy's Enhanced Gas Turbine Emissions Technology Wins Ecomagination Rating

DLN 1+ Combustion System Achieves Five PPM or Less

ATLANTA, GA. - May 25, 2007 - Under the rigorous guidelines of GE's ecomagination program, GE Energy continues to develop technology that helps power plant operators meet increasingly strict environmental standards. Among the latest products to receive ecomagination certification is the GE Dry Low NOx (DLN) 1+ combustion system, which guarantees nitrous oxide (NOx) emissions of five parts per million (ppm) or less for GE Frame 6B, 7E and 7EA gas turbines.

Ecomagination is the company's commitment to address challenges such as the need for cleaner, more efficient sources of energy, reduced emissions and abundant sources of clean water. The DLN 1+ technology recently received ecomagination certification after completing a demanding environmental and operational evaluation.

The enhanced emissions technology was among the products featured at GE's ecomagination launch yesterday at Universal City, Calif.

"Currently, there are several options available to help customers meet revised government regulations and business requirements that demand cleaner emissions," said Dan Heintzelman, president of GE Energy's services business. "They range from new
post-combustion systems to retrofitting the existing combustion system to buying NOx credits, where possible, or even unit retirement. The challenge faced by many customers is to find the solution with the lowest cost and lowest impact to current plant operations."

"GE's DLN 1+ combustion system offers a cost-effective retrofit solution, by replacing an existing combustion system and providing lower NOx emissions. Upgrading the existing DLN 1 system with a DLN1+ system will give customers the ability to further reduce emissions with guaranteed NOx emissions to sub three to five ppm, representing a 45-67 percent reduction," he added.

The DLN 1+ system manages the combustion process to reduce the amount of NOx generated and in some cases it will enable little to no CO emissions. Prior to the introduction of this technology, the only options available to equipment owners who had to meet three to five ppm NOx levels were post-combustion or selective catalytic reduction (SCR) systems. Installing SCR systems on existing units can be difficult due to site limitations and high capital cost. Also, SCR systems require the use of ammonia, adding to the operating cost of the facility.

In addition to improved emissions performance, the DLN 1+ technology is designed to increase gas turbine combustion inspection intervals to 24,000 hours, based on natural gas operation.
