Lakeside Power Station (non-operational)

The Lakeside Power Station was the original generating facility constructed in the mid-1930s on the shore of the utility's then-new man-made Lake Springfield. By the mid-1960s, Lakeside consisted of eight coal-fired boilers and seven turbine-generators. Two of these—boilers 7 and 8 and turbine units 6 and 7, which have a combined maximum capacity of 76 MW—remained active in meeting intermediate customer load until mid-2009. However, age and increasingly stringent emissions control requirements have been taking their toll on the old Lakeside plant and, rather than spending the multi-millions of dollars that would be needed to bring the old units into compliance with state and federal standards, in 2002 the utility decided instead to construct a new, larger, state of the art, environmentally friendly power plant and, upon its completion, cease using the Lakeside units. The new Dallman 4 Power Station first went online in May 2009, at which time, Lakeside units 6 and 7 became non-operational.
