Sunbury accounts for shutdown of Pennsylvania coal units

Due to the deactivation in July of its coal-fired units, Sunbury Generation LP 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 Interconnection that it planned to deactivate the four coal units as of July 18. On May 14, PJM approved that plan. Considering the minimal capacity left operating at the plant, the decision was to terminate the reactive power tariff.

PJM’s May 14 approval letter, attached to the Sept. 24 filing, noted that the company in November 2013 originally filed a notice of a plan to deactivate the coal units in June 2015. Then that was moved up to July of this year.

The PJM letter notes 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 LLC request to interconnect a 381-MW resource consisting of one heat recovery steam unit (the new Unit 8). A System Impact Study from PJM, dated September 2014, said that Units 1, 2, 3, and 4 are being retired at the Sunbury plant, the site for this new facility. The planned Sunbury Units 5, 6, and 7 are not impacted by this project. Queue Z1-090 is currently scheduled for commercial operation on June 1, 2017.
