FACILITIES

DEC meets the heating and cooling needs of its customers with district heating and cooling systems. It comprises four thermal energy plants in Lincoln, Neb.: one adjacent to the Lancaster County Adult Detention Facility (located at SW 40th & O Street), one at 14th and K streets, one at 9th and K streets, and one at Arena and P streets.

 

Thermal energy produced at these plants is distributed to customers through an underground network of insulated pipes.

These systems use 10-15 percent less energy than the conventional heating and cooling systems traditionally installed in buildings today.

 

West Haymarket District Energy System

 

Commissioned in September 2013, this $18.5 million plant provides heating and cooling thermal service to 845,500 square feet of space in the newly developed West Haymarket district, which includes the Pinnacle Bank Arena (home of the Nebraska basketball teams), retail, apartments/condominiums, hotel and office space.  

 

Lancaster County Adult Detention Facility Thermal Plant

 

Commissioned in May 2012, this $16.8 million plant provides heating and cooling thermal service, as well as emergency electrical service to the new 700-bed Lancaster County Adult Detention Facility. The plant utilizes a 667-borehole geothermal well field and 25 water-to-water heat pumps to provide the detention facility chilled and hot water for space heating and domestic hot water production. The DEC also installed 4.8 megawatts of emergency generation to provide the detention facility and thermal plant backup electrical service.

 

14th and K Street Plant

 

This $3.2 million facility became operational in the winter of 1999. It uses gas-fired boilers to produce high-pressure steam that heats the Nebraska State Office Building, State Capitol and State Administrative Office (a total space of 1,010,000 square feet).

 

9th and K Street Plant

 

Commissioned in June 1991, this $4.7 million facility uses a combination of chillers, gas- and oil-fired boilers and thermal ice storage to meet the heating and cooling needs of the Lancaster County and city of Lincoln government complex. The 612,000 square feet of office and records storage space is spread over six buildings.
