ESC Tioga pursues gas-fired project in Pa., 250 MW of which will be in PJM

ESC Tioga County Power LLC has proposed a natural gas-fired generating facility located in Tioga County, Pa., said PJM Interconnection in a study on the project dated April 2016.

The installed facilities will have a total capability of 250 MW with 250 MW of this output being recognized by PJM as capacity. The proposed in-service date for this project is June 2020. This study does not imply a Pennsylvania Electric (Penelec) commitment to this in-service date.

This project, under PJM queue #AA2-120, will interconnect with the Penelec transmission system at the Tower Hill 115-kV substation. The interconnection of the project at the Tower Hill 115-kV substation will be accomplished by expanding the station to a four breaker ring bus layout. The station will be designed to allow for future expansion to a six breaker layout.

Project AA2-120 was studied with a commercial probability of 100% using a Summer Peak 2019 case.

A diagram contained in the study shows the project that will interconnect to the PJM system is a 250-MW combustion turbine system, but adds in a footnote: “Customer is proposing to construct a combined cycle plant with the additional units connected to NYSEG’s 345kV system. The lower voltage aux system will include ties between the 115kV and 345kV units. These lower voltages systems should not be parallel under any circumstances; all transitions must be break-before-make and include a key interlock system.” NYSEG is New York State Electric and Gas, which is in the New York ISO. The study doesn’t show a MW rating for the whole project.

The intent of this System Impact Study is to determine a plan, with approximate cost and construction time estimates, to connect the subject generation interconnection project to the PJM network at a location specified by ESC Tioga County Power. The study is a mid-point in the PJM queue process.

A company logo in a map contained in the study shows this is a project of Energy Solutions Consortium LLC. Says that company’s website: “Energy Solutions Consortium LLC (ESC) focuses on development of combined cycle power generating and liquid natural gas (LNG) processing facilities incorporating state-of-the-art technologies to deliver low emissions and reduced carbon footprint, natural gas driven energy solutions. Energy Solutions targets ‘brownfield’ projects to provide productive reuse solutions to former industrial sites, thereby rejuvenating both local landscapes and economies. ESC is focused on the opportunities provided by the abundant natural gas in the Appalachian basin.”

The website says that company President Andrew “Drew” Dorn IV has extensive experience in the North American deregulated electricity and natural gas markets, particularly structuring energy transactions for some of the largest wholesale and retail consumers in the Northeast and mid-Atlantic regions, including regulated utilities, independent power producers, and energy intensive industrials. He founded and was CEO of Demand Response Partners Inc. (DRP) an energy advisory firm and leading demand response supplier to the PJM Interconnection and New York Independent System Operator which he sold to CPower in 2015.
