AEP readies 7,582 MW of coal capacity for retrofits, refueling

American Electric Power (NYSE: AEP) said in a presentation Nov. 13 at the annual EEI Financial Conference that it has a total of 7,582 MW of coal-fired capacity that is projected for emissions control retrofits or refueling with natural gas.

These units are spread out among AEP’s AEP Ohio, Appalachian Power, Indiana Michigan Power, Kentucky Power, Public Service Co. of Oklahoma and Southwestern Electric Power subsidiaries. The new technologies being planned include: baghouses for particulate control; activated carbon injection (ACI) for mercury; dry sorbent injection (DSI) and flue gas desulfurization (FGD) for SO2; and selective catalytic reduction (SCR) for NOx control.

Kentucky Power’s 800-MW Big Sandy Unit 2 is on the list as being under evaluation. The utility in May withdrew an application at the Kentucky Public Service Commission for approval of an FGD project for Big Sandy Unit 2, saying the economics of that project may have changed.

Here are the retrofit/refueling plans, by subsidiary. The power ratings are AEP’s share of any given unit, where applicable.

AEP Ohio:

  • Conesville Unit 5, 400 MW, ACI and DSI.
