June 1 was a big, and for some power generators, a pretty bad day for the shutdown of various power generating units, especially for American Electric Power (NYSE: AEP).
PJM Interconnection on June 10 released the latest version of its deactivated power plant list, and there is an unusually long section of the list devoted to June 1 deactivations.
Much of that is due to the long-planned shutdown of these coal-fired units of AEP in Indiana, Kentucky, West Virginia, Virginia and Ohio: Clinch River Unit 3, Glen Lyn Units 5-6, Kammer Units 1-3, Kanawha River Units 1-2, Muskingum River Units 1-5, Picway Unit 5, Sporn Units 1-4, Tanners Creek Units 1-4 and Big Sandy Unit 2. The biggest single units in that group are Big Sandy Unit 2 (800 MW), Muskingum River Unit 5 (600 MW) and Tanners Creek Unit 4 (500 MW).
There were also a number of June 1 deactivations of smaller oil- and gas-fired units in New Jersey of Public Service Enterprise Group (NYSE: PEG), which said about these shutdowns in its Feb. 26 annual Form 10-K report: “The National Park, Sewaren 6, Mercer 3, Salem 3, Burlington 8 and 11, Bergen 3, Edison 1, 2 and 3 and Essex 10, 11 and 12 peaking units are scheduled to be retired in June 2015. Salem 3 is expected to continue to be used as an emergency backup generator for the Salem nuclear site.” Example June 1 deactivations from the PJM list include Bergen Unit 3 (21 MW), Burlington Unit 8 (21 MW), National Park Unit 1 (21 MW), Mercer Unit 3 (115 MW) and Sewaren Unit 6 (111 MW).
