The start-up of the 200-MW Dallman 4 in Summer 2009 allowed CWLP to stop using the last two operating, 1960s-vintage generating units at Lakeside Power Station, which was originally built in 1935 on the shore of the then newly constructed Lake Springfield.

In addition to the power self-generated by CWLP, the utility contracts for wind power from NextEra Energy Resources (formerly FPL Energy).

2010 Facts and Figures
In 2010, the utility generated 2,583,425 megawatt-hours (MWH) of electricity and had system purchases of 537,308 MWH, for a total system input of 3,120,733 MWH. This served the native energy requirement of 1,924,424 MWH, as well as system wholesale sales of 1,196,309 MWH.

Of the 537,308 MWH purchased by CWLP in 2010, 290,369 MWH was in the form of wind energy purchased from the Hancock County and Crystal Lake wind farms in Iowa. The average wind capacity factor was 27.62%. CWLP paid $13,341,404 ($45.95/MWH) for the wind energy and sold it for $6,493,814 ($22.36/MWH), for a net cost to the utility of $6,847,590 ($23.58/MWH). Wind energy equaled 10.1% of net generation and 15.09% of native energy.

In 2010, CWLP's four coal-fired units consumed a total of 1,397,170 tons of coal, 100% of which was mined in Illinois. All generating units consumed over 374,058 gallons of fuel oil and nearly 507,812 dekatherms of natural gas.

In 2010, CWLP's summer peak demand was 429 MW, set on Tuesday, August 15 at 4 p.m., when the outdoor temperature was 97° F and the heat index was 111° F. This represents a 4.9% reduction from the  record peak of 451 MW set in 2006. 

During Winter 2010/2011, CWLP did not set a record peak demand. The highest peak demand for the season—290 MW—was set on Friday, January 21, 2011, at 7 p.m. (air temperature: 8°; wind chill: -4°), and again on Thursday, February 10, at 8 a.m. (air temperature: -1°; wind chill: -1°). CWLP's record winter peak of 325 MW was set on  January 25, 2009.

Independent power generators interested in interconnecting to CWLP's transmission system can link to information needed to assist them in this process from our Interconnection Information page.
