Combined Heat and Power Plant
Projected Boiler Capacity Shortage Threatens University Research and Teaching
- The University's Minneapolis campus encompasses
approximately 18 million square feet throughout
163 buildings with growing heating, cooling, and
- The University's Utility Master Plan anticipates
a shortage in boiler capacity for the Minneapolis
campus beginning in 2015 due to increasing demand
and aging equipment.
- One of the University's boilers currently in use will
need to be decommissioned in 2015, magnifying
supply and demand issues.
- Last year, the University saved $2.6 million
and 29,000 tons of CO2 as a result of energy
conservation initiatives; however, these efforts
cannot remedy the growing demand.
Old Main Steam Plant Is the Preferred Solution
- Old Main was built in 1912 to heat the Minneapolis
campus. The building is currently decommissioned.
- The building's location will allow the University
to meet peak demand at a significantly lower
construction cost than a remote campus site.
- The building is large enough to serve as a multiutility
plant without constructing additional
- Old Main's deficiencies need to be addressed.
Renovate Old Main to Be a Multi-Utility Plant
- Add two seven-megawatt natural gas fired turbines
as a combined heat and power system with heat
recovery steam generators.
- Replace inefficient, WWII-era coal burners.
- Construct systems to support a future chilled water
cluster plant and another natural gas boiler.
- Address the Old Main's deficiencies.
- Protects research currently vulnerable to shortages
by providing a second source of steam production.
- Reduces Risk. The current practice of depending on
one plant for 100% of the campus's heat has been
cited as a top property insurance risk for the campus.
- Provides needed steam peak capacity for at least
the next 15 years.
- Reduces the campus carbon footprint by 10 percent.
- Uses the waste heat from generating electricity
to increase efficiency.
- Reduces University utility costs by a projected $1.9
million annually, assuming projected natural gas and
electric cost for 2014.*
- Saves the University an additional $4.1 million in
debt service with two-thirds state bonding support.
- Provides a financial hedge against future electric
- Creates a cost-effective site for a future chilled water
