Caithness Energy orders GE’s HA gas turbines for Ohio plant

Published on: 

Caithness Energy has ordered three of GE’s record-setting 7HA.02 gas turbines for its 1,875-megawatt, combined-cycle, natural gas electric generating facility—the Guernsey Power Station—in Guernsey County, Ohio.

In addition to GE’s 7HA.02 gas turbines, the world’s largest and most-efficient heavy-duty gas turbines, the order also includes heat recovery steam generators and steam turbine generators for each 7HA.02 unit, which will produce the equivalent electricity needed to power approximately 1.5 million homes within the PJM region.

GE will also service the facility under a multi-year services agreement and provide digital solutions to combine equipment sensor data with predictive analytics through GE’s Asset Performance Management (APM) software and managed services.  The APM software solution will monitor assets at Guernsey and predictive analytics will proactively recommend appropriate preventative maintenance to enhance plant reliability.


Caithness Energy partnered with Apex Power Group to develop the Guernsey Power Station in the Utica and Marcellus shale region. When completed, it will be managed by Caithness Energy and will sell energy, capacity and ancillary services into the PJM segment, which provides electricity to millions of customers across thirteen states and District of Columbia . Gemma Power Systems, a wholly owned subsidiary of Argan, Inc., will be the engineering, procurement and construction company responsible for the project, which is scheduled to be completed in the fourth quarter of 2022.

Earlier in 2019, GE announced that the HA will power the approximately 620-megawatt Hill Top Energy Center in Nemacolin, Pennsylvania; as well as an order for the Indeck Niles Energy Center in Niles, Michigan.
