Largest Geothermal Project in U.S. is Half Complete

The United State’s largest geothermal project at Ball State University in Indiana has reached the half way point.   Ball State University is leading the way in the implementation of geothermal by installing a system that will help heat and cool 47 buildings on its campus.

The project entails the installation of  thousands of 400 to 500 ft boreholes and over 1,000 miles of geothermal loop to heat and cool over 20,000 gallons of water per minute to serve roughly 6 million square feet of space.

With a 650%  increase in efficiency over the previous system (coal-fired boilers), Ball State University estimates to save approximately $2 Million per year in savings over a 30 year period.

Many of the country’s universities are paying close attention to the project as a test case to see if geothermal makes sense for their campuses.
