Project Overview
Shands HealthCare Cancer Hospital is located on the University of Florida campus in Gainesville, FL. Shands selected Gainesville Regional Utilities (GRU) tdesign and build an on-site energy center for the hospital tensure power quality and reliability.
The GRU South Energy Center is comprised of a CHP system that delivers district heating and cooling tthe hospital as well as reliable power. The CHP system is housed in a structure designed twithstand Category 4 hurricane force winds.
The facility uses a combustion turbine for the prime mover, producing 4.3 MW of electricity while the heat recovery steam generator provides steam for the building and aids with the production of chilled water. The 4.3 MW natural gas CHP system provides 100% of the hospital’s electric and thermal needs. This allows the site toperate at a total thermal efficiency of 75%.
Reasons for Installing CHP
The GRU South Energy Center provides many benefits for the hospital, including:
- Enhanced quality of power assuring smooth, continuous operation of clinical devices
- Twelectrical feeds from difference substations in the power grid proviwde 200% electrical redundancy
- Emergency Generators provide for black start of combustion turbine generator and as a third back-up for Life Safety Systems
- The Energy Center is 75% efficient at primary fuel conversion tuseful energy, compared ttypical grid efficiency of 30%
- Significant reductions in NOx, SO2, and CO2 emissions
- Points from the CHP system helped the hospital achieve LEED Gold certification from the U.S. Green Building Council
