Alabama Power has modernized drives for most major air dampers on two coal-fired generating units — 90 drives in all. Replacing vintage actuators with new "smart" electric drives eliminates high maintenance costs and offers large fuel savings on coal-fired boilers.

Installations took place at the company's 25-year-old James H. Miller, Jr. Plant near West Jefferson, AL. Each unit has a nominal generating capacity of 720 MW.
