Our Story

Utility Bill Advocates since 1979.


TriStem audits utility bills for large consumers of electricity. Recoveries and savings that have accrued to TriStem’s clients are in the hundreds of millions of dollars. No other company in the U.S. can match TriStem’s record. Utility bill audits is what we do. 

TriStem is a business which has called Texas home for 40 years. Rather, our experience goes far beyond Texas borders. We have had clients in all 50 states, Canada and Puerto Rico. Our past clients include state agencies in Oregon, Nebraska, Washington, Arizona, Louisiana, Missouri, Texas, and Michigan. Also, our Federal clients include the General Services Administration, United States Postal Service, Coast Guard, and Veterans’ Administration Hospitals.
