LES’ oil- or natural gas-fired power plant with one simple-cycle combustion turbine totaling 29 megawatts was installed in 1972.
LES’ primary peaking power station with three oil- or natural gas-fired simple-cycle combustion turbines totaling 255 megawatts including a 3-MW diesel gen-set. The combustion turbines were installed in 1975, 1996 and 2001.
LES’ oil- or natural gas-fired, 167-MW plant uses waste heat from two aero-derivative combustion turbines to create steam, which is used to operate a steam turbine and generate additional power in a combined-cycle configuration. A third aero-derivative combustion turbine is operated in simple cycle. The plant also has a 2-MW “Black Start” unit on-site. The combustion turbines were placed in commercial operation in 2003 with the steam turbine following in 2004.
LES completed construction of a 5-MW, landfill gas-generated facility in 2014. The methane fuel is supplied from the Bluff Road Landfill.
LES purchases 56 MW of firm power, 72 MW of summer firm peaking, and 22 MW of winter firm peaking power from this hydropower resource. LES’ contract routinely has been extended by amendment and currently runs through 2020.
LES has two wind turbine generators on the northeast side of Lincoln. The first wind turbine generator was completed in December 1998 and the second in October 1999. At full output, the turbines are capable of generating a combined total of 1 MW of power.
LES began receiving energy from a share of the Elkhorn Ridge Wind Farm in March 2009, located five miles north of Bloomfield in northeast Nebraska. LES entered into a power purchase agreement for 6 MW of the total 80-MW wind project, which consists of 27 wind turbines.
LES began receiving energy from a share of the Laredo Ridge Wind Farm in February 2011, located northeast of Petersburg, Nebraska, in Boone County. LES entered into a power purchase agreement for 10 MW of the total 80-MW wind project, which consists of 54 wind turbines.
In November 2012, LES began receiving energy from a share of the Crofton Bluffs Wind Farm located southwest of Crofton in northeast Nebraska. LES entered into a power purchase agreement for 3 MW of the total 42-MW wind project, which consists of 22 wind turbines.
LES began receiving energy from a share of the Broken Bow Wind Farm in December 2012. LES entered into a power purchase agreement for 10 MW of the total 80-MW wind project, which consists of 50 wind turbines. The project is located just east of the community of Broken Bow in central Nebraska.
LES began receiving energy from the Arbuckle Mountain Wind Farm in November 2015. LES entered into a power purchase agreement for the full 100-MW project, which consists of 50 wind turbines. The project is located in south-central Oklahoma, about 80 miles south of Oklahoma City.
LES began receiving energy from the Buckeye Wind Energy Center in October 2015. LES entered into a power purchase agreement for the full 100-MW project, which consists of 56 wind turbines. The project is located in north-central Kansas, about five miles north of Hays, Kansas.
LES began receiving energy from the Prairie Breeze II Wind Energy Center in December 2015. LES entered into a power purchase agreement for the full 73-MW project, which consists of 41 wind turbines. The project is located in northeast Nebraska, about five miles east of Elgin, Nebraska.
In August 2014, LES launched the SunShares program, allowing customers to voluntarily support a local community solar project. This nearly 5-megawatt project is located at 75th & West Holdrege in Lincoln and went online June 2016.
LES owns 12.76 percent of this coal-fired power plant with approximately 10.5 percent, or 179 MW, available after ownership and participation sales. Construction was completed in 1982 on the three-unit, 1,710-MW plant.
Owned by Nebraska Public Power District, LES participates under a life-of-plant contract by purchasing 8 percent of the output, or 109 MW. The final phase of this coal-fired plant was completed in 1982.
LES owns 12.66 percent of Walter Scott, Jr. Energy Center Unit 4 near Council Bluffs, Iowa, along with MidAmerican Energy Company and 12 other companies. The 816-MW, coal-fired plant was completed in 2007 and provides LES 103 MW. To further diversify generation, in January 2008 LES executed an agreement with MidAmerican to exchange energy derived from 50 MW of Unit 4 with 50 MW of Unit 3.
*LES is selling the Renewable Energy Credits associated with these generating resources; the renewable attributes are transferred to the REC recipient. Renewable Energy Credits represent a right to market characteristics associated with renewable generating facilities. One credit is created for every megawatt-hour of energy generated by a renewable resource. Renewable Energy Credits are also commonly referred to as Green Tags, Renewable Energy Certificates, Tradable Renewable Certificates, and environmental attributes.
