51-MW Perryman Unit 2 in Maryland was deactivated on Feb. 1

PJM Interconnection in a Feb. 2 update of its list of deactivate power units said that on Feb. 1, the 51-MW Perryman Unit 2 in Maryland joined the growing list of deactivated facilities. 

Said a notation in the list about this facility: “Reliability analysis complete. One impact identified, resolved via an existing baseline upgrade, which is expected to be completed by June 2017. Interim operating measure identified and can be utilized until baseline upgrade complete. Unit expected to deactivate as scheduled. Unit deactivated on 2/1/2016.” As usual, PJM didn’t identify the operator of this facility.

Constellation Power Source Generation LLC (CPSG) on Jan. 19 filed with the Federal Energy Regulatory Commission new information needed due to the retirements of its Perryman Unit CT 2, scheduled for Feb. 1, 2016, and in anticipation of the subsequent retirement of Riverside Unit 4, which is scheduled for June 1, 2016. CPSG is an indirect, wholly owned subsidiary of Exelon Generation Co LLC and an affiliate of Baltimore Gas and Electric (BGE). 

CPSG previously experienced changes in its fleet in the BGE Zone with the retirement of the Riverside Unit CT 6 in June 2014, and more recently with the addition of the Perryman Unit CT 6 in June 2015.

Perryman is made up of six units, fired by oil and gas, with 463 MW of net capacity. Those figures include: Perryman Unit 2, with 51 MW of net capacity, which is the one due to retire; and the new Perryman Unit 6 (110 MW net), which went into commercial operation in June 2015.

Riverside has three units, is fired by oil and gas, and has 113 MW of net capacity. Those figures include Riverside Unit 4 (74 MW net), which is the one due to be retired.

Incidentally, PJM on Feb. 2 also released an updated pending deactivation list, which still lists June 1 for the shutdown of Riverside Unit 4, noting: “Reliability analysis complete. No issues identified. On 4/17/2014 Riverside submitted an updated deactivation notice with a new deactivation date of 6/1/2015. New reliability analysis complete. No issues identified. Gen owner will keep unit operating until 6/1/2016.”
