PJM files revision of interconnect deal for Sunbury power project

PJM Interconnection filed with the Federal Energy Regulatory Commission on Nov. 19 an executed interconnection service agreement among PJM, Corona Power LLC and transmission owner PPL Electric Utilities.

This Revised Corona ISA supersedes an ISA among the same parties, which was designated as Original Service Agreement No. 3769, with an effective date of Feb. 4, 2014, and filed with and accepted by the commission. “The Revised Corona ISA facilitates the interconnection to the PJM transmission system of 643 MW at three generating units (consisting of 227 MW to Unit #5, 208 MW to Unit #6, 208 MW to Unit #7),” said the filing.

These new units will be at the Sunbury Generation Facility located at Shamokin Dam, Pennsylvania. They are described in the agreement as three new gas combustion generators. Each generator is to be connected to a 18-kV circuit breaker and 18/512-kV step-up transformer. These are projects #X2-025 and #X4-019 in the PJM project queue.

The old agreement had a June 1, 2016, commercial operation target date. That has been revised to Sept. 1, 2017.

The project contact is: Corona Power LLC c/o Sunbury Generation LP, Old Trail Road, Shamokin Dam, PA 17876, Attn: Jeff Specht.

Due to the deactivation in July of its coal-fired units, Sunbury Generation filed a Sept. 24 notice with the Federal Energy Regulatory Commission of the cancellation of a reactive power and voltage control tariff. Sunbury owns a 436-MW power plant in Snyder County, Pa., that includes four coal-fired units (Units 1-4), two oil-fired combustion turbine generators and two diesel generators. The company noted that it filed an April 14 notice with PJM that it planned to deactivate the four coal units as of July 18. 

The PJM letter said that the company retains its Capacity Interconnection Rights for the Sunbury facility related to a project with a queue number of Z1-090. Queue position Z1-090 is a Corona Power request to interconnect a 381-MW resource consisting of one heat recovery steam unit (the new Unit 8). The planned Sunbury Units 5, 6, and 7 are covered by the queue numbers in the Nov. 19 filing at FERC.
