Dynegy hires GE to upgrade, uprate four power plants

General Electric‘s (NYSE: GE) Power Services business announced Dec. 8 that Dynegy (NYSE: DYN) is installing GE hardware and software equipment to upgrade and modernize four of its power plants—three of which the company recently purchased.

Dynegy is upgrading the plants to enhance their reliability and increase their output by a total of 210 MW. For the projects, GE will supply a total of eight sets of Advanced Gas Path (AGP) upgrades and GE’s OpFlex Peak Fire software for the fleet of 7FA.03 gas turbines at Dynegy’s Hanging Rock Energy Facility and Washington Energy Facility in Ohio and the Fayette Energy Facility in Pennsylvania.

In addition to those recently-acquired stations, Dynegy also is upgrading its Independence Energy Facility in Oswego, New York, with four sets of AGP hardware to boost output and enhancing compressor performance and reliability through the installation of new compressors and stators. 

“Dynegy is always looking for ways to economically increase output, reliability and efficiency at our power stations while upholding our commitment to safety and environmental responsibility,” said Marty Daley, executive vice president, Dynegy. ”Through our collaboration with GE, Dynegy is upgrading four of our facilities with some of the latest technologies to achieve these goals.”

“Dynegy was one of GE’s early adopters for 7F Advanced Gas Path gas turbine technology, and their decision to implement additional upgrades clearly speaks to the success of this technology and our collaboration together,” said Paul McElhinney, president and CEO of GE’s Power Services business. “Dynegy’s upgrade projects illustrate how more utilities are using our customized software and hardware solutions such as AGP and OpFlex software to increase the efficiency and reliability of their mature power plants.” 

With GE’s OpFlex Peak Fire, power plant capacity can be expanded by boosting baseload output by up to 8%, enabling customers to capture higher peak demand revenue. The company’s full suite of OpFlex software solutions can help reduce fuel consumption to lower operating costs at part-load conditions, extend turndown while maintaining emissions compliance to improve availability, increase output to capture new revenue opportunities, decrease start time and fuel costs to economically respond to cyclical power demands and shorten outages and increase availability through an intelligent control system.

The AGP and compressor components for the upgrades will be supplied by GE’s gas turbine facility in Greenville, South Carolina. The first two units were upgraded in the fall of 2015 and work is expected to be completed by the fall of 2016.

With nearly 26,000 MW of power generation capacity and two retail electricity companies, Dynegy is capable of supplying 21 million homes with safe, reliable and economic energy.
