There were three power generating units in PJM deactivated around the end of 2012, with one of them being the 165-MW, coal-fired Conesville Unit 3 of American Electric Power (NYSE: AEP).
An updated list of deactivations issued Jan. 10 by PJM shows that AEP requested the deactivation of this 49-year-old unit on March 22, 2012, and that Conesville 3 was actually deactivated on Dec. 31, 2012. Said the PJM list about grid reliability issues related to this Ohio facility: “Reliability Analysis complete – impacts identified – upgrades scheduled to be completed by June 2014. Generator has deactivated as planned on December 31, 2012.”
The other two recent deactivations, by the PECO unit of Exelon (NYSE: EXC), were done on Jan. 1 and requested on Oct. 31, 2012. One was of the 166-MW, 54-year-old Schuylkill Unit 1, and the other was of the 3-MW, 45-year-old Schuykill Diesel facility. Schuylkill 1 is a peaking oil unit located in Philadelphia, Pa., which was placed in service in 1958.
PJM also issued an updated pending deactivation list as of Jan. 10. The only other coal units listed under AEP are all due to be deactivated by June 2015 and include units at the Big Sandy, Clinch River, Glen Lyn, Kammer, Kanawha River, Muskingum River, Picway, Sporn and Tanners Creek plants.
PJM’s pending deactivation list now totals 10,945 MW of capacity, most of it coal-fired.
