Facilities

Natural gas

8th & J

LES’ oil- or natural gas-fired power plant with one simple-cycle combustion turbine totaling 29 megawatts was installed in 1972.

Rokeby Generation Station

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.

Terry Bundy Generating Station

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.

Renewable

Bluff Road Landfill Gas to Energy*

LES completed construction of a 5-MW, landfill gas-generated facility in 2014. The methane fuel is supplied from the Bluff Road Landfill.

Western Area Power Administration

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.

Prairie Breeze II Wind Energy Center

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.

LES SunShares

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.

Coal

Laramie River Station

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.

Sheldon Station

The coal-fired plant, owned by Nebraska Public Power District, was completed in 1968. LES participates under a life-of-plant contract by purchasing 30 percent of the output, or 65 MW.

Gerald Gentleman Station

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.

Walter Scott, Jr. Energy Center Unit 4

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.
