Dayton Power & Light (DP&L) deactivated the 62-MW OH Hutchings Unit 4 on June 1, with the other five coal units at the Ohio plant due to be deactivated by June 1, 2015, said updated lists of pending and executed deactivations issued June 4 by PJM Interconnection.
The deactivation of Hutchings Unit 4 has been the first for a power generating unit in the PJM region since the Jan. 1 deactivation of the 3-MW Schuylkill Diesel facility, the PJM list of finished deactivations shows.
The list of pending deactivations shows that Hutchings Unit 1 (53 MW), Unit 2 (50 MW), Unit 3 (59 MW), Unit 5 (58 MW) and Unit 6 (57 MW) are due to be shut down by June 1, 2015. PJM indicated that there are no grid reliability concerns that would impede those deactivations.
The current deactivation list for PJM holds a total of 11,354.5-MW of capacity, most of it coal-fired, that would be shut out through 2015.
The PJM pending deactivation list related to Hutchings is a bit misleading. DP&L has informed PJM that Hutchings Unit 4 has incurred damage to a rotor and will be deactivated June 1 and that the remaining Hutchings coal units will no longer be operated after May 2013 and will be deactivated by June 1, 2015, said parent DPL Inc. in its Feb. 27 annual Form 10-K report.
Hutchings is a 365-MW (summer) coal plant, owned entirely by DP&L, that is located at Miamisburg, Ohio. Its retirement, due to age and new emissions control burdens, has been expected for some time. DPL Inc. is a unit of AES Corp. (NYSE: AES).
