Powering Liberty

US$400 million order includes long-term maintenance, service contract

Posted on August 22, 2013

Siemens Energy has received an order for the supply of two power plant units with H-class gas turbines for the Liberty combined-cycle power plant in Pennsylvania, U.S.A. The end customer is a subsidiary of Panda Power Funds.

The Liberty power plant will be erected by Gemma-Lane and consist of two power plant units, which will be established as single-shaft configurations, each with an H-class gas turbine as the main component. The plant will have an electrical capacity of 829 MW in combined-cycle duty.

The Liberty power plant is to be erected in the Asylum Township in Bradford County, Pennsylvania, U.S.A., and will be the first power plant on the Marcellus gas field, the company said. The Liberty plant will be fired entirely by the shale gas reserves present in this field.

Siemens will supply two power islands for the plant, each consisting of one SGT6-8000H gas turbine, one SST6-900 steam turbine, one water-cooled SGen-2000H generator and one heat recovery steam generator, along with the overall electrical system and the SPPA-T3000 I&C system.

Siemens said the H-class technology will make the plant one of the most modern gas-fired power plants on the East Coast of the U.S., able to supply up to one million homes with clean power. Commissioning of the plant is scheduled for 2016.
