Shell Chemical Appalachia LLC has proposed to PJM Interconnection a gas-fired generating facility, composed of three simple cycle gas turbine generators (GTGs) and two steam turbine generators (STGs), located in Monaca, Pa.
“The installed facilities will have a total capability of 205 MW with 97 MW of this output being recognized by PJM as capacity,” said a PJM-authored Facility Study on the project dated January 2015. “The proposed in-service date for this project is July 1, 2018. This study does not imply a Duquesne Light Company (DLCO) commitment to this in-service date.”
This project, under PJM queue #Y3-103 and an application first filed in April 2013, will interconnect with the Duquesne transmission system with two radial transmission lines from the planned Potter 138-kV substation. The addition of the Potter substation must be completed prior to the operation of this queue project. This proposed substation will be at the site of the former St. Joseph Mineral 138-kV substation.
The town of Monaca is on the Ohio River, northwest of Pittsburgh near the state line with Ohio. Shell is known in this report as the Interconnection Custmer (IC). Said the study: “IC has proposed construction of a 205 MW net output natural gas fueled generator at the site of the former St. Joe Mineral customer. This site is located along the Ohio River at 300 Frankfort Road, Monaca, PA 15061 in Beaver County, Pennsylvania.”
This study is an interim step in a queue process that culminates with the signing of an Interconnection Service Agreement.
