York 2 dual fuel power plant in commercial operation as Calpine, McDermott complete work

Competitive market power generator Calpine Corp. said its latest combined-cycle plant is now in operation.

The York 2 Energy Center in Peach Bottom Township, Pennsylvania, began commercial operation on Sunday. The 828-MW York 2 joins the 565-MW York 1, which has been producing power since 2011.

York uses dual-fuel combustion turbines burning primarily natural gas, but they can also run on ultra-low-sulfur diesel when needed.

“Plants with flexible, dual-fuel capabilities like our York energy centers are playing an increasingly important role in ensuring power reliability in the PJM region,” said Calpine’s President and CEO  Thad Hill. “Importantly, York 2 was built and will operate cost effectively without the need for government or public subsidies, demonstrating that letting the competitive markets work is the best way to optimize generation resources.”

Exhaust heat from the two gas-fired combustion turbines is then diverted to heat recovery steam generators to create more power. York’s capacity will compete through the PJM Interconnection auction market.

McDermott International handled engineering, procurement and construction work on the York 2 project.

“Thank you to the McDermott project team who has maintained the highest levels of focus, dedication and safety to achieve this milestone on this world-class power station,” said Mark Coscio, McDermott’s senior vice president for North, Central and South America.

GE delivered two of its 7F.05 gas turbines for the power plant. Both GE and McDermott were awarded the contracts in 2014.

Calpine Corp. now has a fleet of 79 power plants in operation throughout North America. Its generation capacity totals 26,000 MW.
