Solar Power Systems at City Facilities

Solar Power Systems at City Facilities

More than two megawatts of solar power is generating renewable energy and reducing operation costs at 19 City of Boulder facilities.

Solar Thermal Systems

Solar thermal systems at the East and South Boulder recreation centers to help offset the cost of heating the swimming pools. The two systems will save the city $14,657 per year and reduce annual carbon emissions by more than 125 tons. When it was installed in 2002, the solar thermal system at the North Boulder Recreation Center was one of the city’s largest solar power systems.

Solar Electric Systems

Solar electric systems offset a portion of city facilities' electric consumption and reduce the load on the community's electric grid. The collective electric output of the systems is more than 1.4 million kilowatt-hours per year. A combination of decreased electric costs and renewable energy credits will save the city $162,655 per year and reduce annual carbon emissions by more than 1,233 tons.

Donated Solar Electric Systems
The solar electric systems at the George Reynolds Branch Library, Park Central building, and Municipal building were donated to the city in 2008. Bella Energy donated and installed the library's solar electric system, while anonymous donors funded the systems at the Park Central and Municipal buildings through the Center for ReSource Conservation (CRC).

Wastewater Treatment Plant Solar Electric System
During the past four years, the one-megawatt solar photovoltaic system at the city's Wastewater Treatment Facility has generated more than six million kilowatt-hours of electricity, saving utility ratepayers more than $200,000. The system began generating clean, renewable power in August 2010 and has operated efficiently and reliably ever since, producing about 14 percent of the facility’s annual power needs.

Electronic Gauges

Electronic gauges provide real-time measurements of each city facility's electrical consumption and solar production, and are used to regulate the solar power systems, enabling the city to reduce peak loads and achieve even greater energy savings through demand-side management.

Energy Performance Contract (EPC)

Solar Electric Systems
In 2011 and 2012, the Energy Performance Contract with the Colorado Energy Office allowed the city to install solar electric systems at 15 city facilities, including:

  • all three Boulder recreation centers;
  • the Main Boulder Public Library;
  • the Betasso and 63 rd Street water treatment plants;
  • the Facilities and Asset Management buildings and the Fleet garage;
  • the Open Space and Mountain Parks (OSMP) Annex, Cherryvale, and Ute buildings;
  • the Municipal Services Center; and
  • The Dairy Center for the Arts.

The new solar electric systems offset a portion of the city facilities' electric consumption and reduce the load on the community's electric grid.

Solar Thermal Systems
Solar thermal systems were also installed at the East and South Boulder recreation centers to help offset the cost of heating the swimming pools. The two systems will save the city $14,657 per year and reduce annual carbon emissions by more than 125 tons. When it was installed in 2002, the solar thermal system at the North Boulder Recreation Center was one of the city's largest solar power systems.
