Geothermal & You - Economic Benefits - Commercial Savings


Operating Costs

Commercial Winter Diagram While geothermal system may be more expensive to install, they can pay back the difference in energy savings in just a few years. And they can typically pay back the full cost in less than 5 years.

According to the U.S. Environmental Protection Agency, geothermal systems average 40 percent greater efficiency than air-source heat pumps, 48 percent better than natural gas furnaces and 75 percent better than oil furnaces.

Detailed Economic Analysis: Alliant Energy's operating facility in Galena, Illinois

The real-life examples below from the Geothermal Heat Pump Consortium show the significant impact geothermal can have on your bottom line:

Commercial Summer Diagram

  • A Conoco Service Station in Sandstone, Minnesota estimates annual energy cost savings of 25 percent for their 4,300-square-foot facility.
  • The Enterprise Center, a 36,000-square-foot office complex in Philadelphia, estimates annual energy cost savings of $29,279.
  • The Daily Family YMCA in Bixby, Oklahoma, cut monthly energy bills by 45 percent compared to similarly-sized YMCAs. They expect a net savings of nearly $100,000 over a ten-year period.

Louisville, Kentucky's Galt House East Hotel expanded its system in 1993, making the office/hotel/apartment complex the world's largest geothermal installation - 1,200 heat pumps with a capacity of 4,500 tons. The facility saves $300,000 a year in energy costs compared to a sister hotel across town. They also saved 25,000 square feet of space and reduced maintenance costs to 7.5 to 10 cents per square foot per year.
