There’s been a fair amount of hand-wringing about the planned closure by American Electric Power’s Appalachian Power subsidiary of the Kanawha River, Philip Sporn and Kammer power plants (see especially Daily Mail stories here and here). Several years after the company’s decisions were announced, all this consternation led staff over at the state Public Service Commission to ask the PSC to investigate the closures.
Lawyers for Appalachian Power responded initially by pointing out that they have actually already provided the commission with a great deal of information on the matter as part of several previous cases. That wasn’t good enough for the PSC, and commissioners ordered the power company to provide more details. Appalachian lawyers did that yesterday, providing this 90-page filing.
Among the more interesting parts of Appalachian’s response:
— Almost all of the operating employees of the Disposition Units have been reassigned or have retired or taken severance.
— Compliance with the MATS Rules would require significant construction work. It might be possible for Disposition Units to meet the requirements of the MATS Rule by constructing Selective Catalytic Reduction (“SCR”) and Flue Gas Desulfurization (“FGD) systems … The installation of SCR and FGD systems would require installation of material handling systems, wastewater treatment systems, Absorber vessels, new ductwork, new stack exhausts, and numerous other systems. APCo has not undertaken any design work for SCR or FGD systems for the Disposition Units because the costs were deemed to be prohibitive, in light of the age and condition of the units.
— Because of the time for the construction of such systems, any Disposition Units at which it was decided to construct these systems could not be returned to service for a minimum of approximately five ( 5 ) years from the date such construction projects were begun.
— The Company has not performed any detailed cost estimates because the order of magnitude of the costs was so tremendous that APCo deemed it imprudent, given the age and condition of the Disposition Units, to have its customers bear such costs, particularly over the comparatively short anticipated lives of any of the conversion or retrofit projects discussed above.
