The utility is also in the process of constructing a new 200-MW coal-fired power plant that is expected to be completed in 2010.
In addition to owning our own generating capacity, CWLP has entered into two long-term contracts to purchase up to 120-MW of wind power.

CONSTRUCTION
The Lakeside Power Station is the original generating facility constructed in the
mid-1930s on the shore of the utility's then-new man-made Lake
Springfield. It consisted
of eight coal-fired boilers and seven turbine-generators, only two of which, boilers 7
and 8 and units 6 and 7, are currently active. Unit #6 was installed in 1961; unit #7
followed in 1965. These turbines have a combined nameplate rating of 66 megawatts (MW) and
a total maximum capacity of 76 MW. Each unit is designed to burn coal with a heat content
of approximately 10,500 Btu per pound. The Lakeside turbines are used to meet intermediate
customer load.
In 2007, Lakeside's two generators generated 266,445 megawatt-hours (MWH) of
electricity. To do this, they used 162,547 tons of coal, 80,245 gallons of
oil, and 6,816 tons of seed corn
costing over $4.97 million. The
station's net fuel cost was $18.67 per MWH.
Particulate emissions at the Lakeside Power Station are controlled by a single
electrostatic precipitator. Water for the unit's once-through cooling systems is obtained
from Lake Springfield and is discharged back into the Lake after cooling the units'
condensers.

Dallman Power Station was built just to the southwest of the Lakeside Station in 1968
to answer the increasing electric demand of a growing city. The first Dallman generator
placed on line was Dallman 1, with a maximum capacity of 86 MW (80 MW nameplate rating). It
was followed by a second 87 MW (80 MW nameplate rating) unit in 1972. Both
of these units employ B&W cyclone boilers. In 1978, a third
turbine-generator, with a maximum capatability of 199 MW (192 MW nameplate rating), more than doubled the
power station's total generating capacity. Unit 3 uses a CE pulverized coal
boiler. These three coal-fired units are intended to
meet customer base load.
In 2007, Dallman's three generators used 970,476 tons of coal, 182,640 gallons of
oil and 7,513 tons of seed corn costing $32.02
million to generate 1,759,577 MWH of electricity. The station's net
fuel cost was $18.20 per MWH.
All Dallman units are designed to burn coal with an approximate heat content of 10,500 Btu
per pound. Particulate emissions from the three units are controlled by electrostatic
precipitators.
In addition, the three units are equipped with flue gas desulfurization systems (scrubbers) to control sulfur dioxide (SO2) emissions. The scrubber for Dallman 3 was installed in 1980. A second scrubber, serving the two older units, was put into operation in June 2001 in response to requirements of the 1990 Clean Air Act Amendments.
The three units have also been equipped with selective catalytic reduction (SCR) systems, which reduce nitrogen oxides (NOX) emissions to levels allowed by both state and federal clean air requirements. The SCRs, which cost a total of $76 million to install, were placed on line in May 2003. They operate during the "ozone season" (May through September) when NOX emissions are most likely to have an impact on atmospheric ozone levels.
All three Dallman units use once-through condenser cooling water systems
with water being obtained from Lake Springfield and discharged back into the lake.
CWLP also owns three 1.825 MW oil-fired diesel generators that serve as a back-up electric supply for the utility.
In 2007, these units used a total of 6,606 gallons of diesel oil costing $15,798 to generate 86.0 MWH of electricity. The unit’s net fuel cost was $183.71 per MWH.
CWLP operates three peaking generators, two that are oil-burning and
one that has dual-fuel operating capabilities. These units have a combined
maximum capacity of 166 MW (147 nominal rating).
Together, in 2007, these peaking turbines used a total of 2,388,150 dekatherms of natural gas costing
$1,821,195 and 72,419 gallons of fuel oil costing $182,100 to generate
19,501 MWH of electricity. The average net fuel cost to operate these units
was $102.73 per MWH.
