Kiewit 569 MW Natural Gas-fired Cherokee Power Plant to Use Less Water than Present

Kiewit Construction was awarded a contract by Xcel Energy to design and construct the planned 569 MW Cherokee combined cycle natural gas-fired power plant in Colorado. Kiewit said this is the company’s first GE 7F-5 Series Project. Construction is scheduled for completion in fall 2015.

          Description:
           Combined cycle

Air emissions are controlled at Cherokee Station by baghouses installed on all three units. Baghouses act like giant vacuum cleaners, removing particulate emissions from the flue gas by more than 99 percent.

The units have low-NOx burners that reduce nitrogen oxide (NOx) emissions by about 40 percent.

Unit 1 also has dry sorbent injection (DSI) systems, and Unit 3 has lime spray dryers. These controls, added as part of Xcel Energy’s voluntary Denver Metro Emission Reduction Plan, will reduce Cherokee's SO2 emissions by about 70 percent from uncontrolled levels.

Xcel Energy is beginning to implement its Colorado Public Utilities Commission-approved Clean Air-Clean Jobs plan. We will early retire Cherokee Units 1, 2 and 3 (365 MW), which operate on coal, and install a cleaner, more efficient natural gas plant (569 MW) at the plant site. We also will switch Cherokee Unit 4 from using coal to natural gas (352 MW).

Here is our anticipated Cherokee repowering project schedule:

·         Unit 2 (106 MW) was retired October 2011

·         Unit 1 (107 MW) retired by June 2012

·         Unit 3 (152 MW) retired by 2015

·         New, 569 MW natural gas combined-cycle generating plant comes online in 2015

·         Unit 4 (352 MW) switched to natural gas in 2017

A new pipeline is needed to deliver the natural gas to our Cherokee power plant for this conversion.

We are proposing to construct approximately 34 miles of new 24” steel gas transmission pipeline from a new Ft. Lupton gas metering facility to the Cherokee Generating Station. Construction on the new natural gas pipeline would begin in 2013 with an anticipated in-service date of Oct. 1, 2014.

Water Use

Testimony by Stacy Tellinghuiesen water analyst  of  western Resources Advocates shows substantial water reduction by closing coal plants and substituting combined cycle
