About TriStem

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. 

Utility Bill Advocates since 1979.

Our Story

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.

Our Stats

Above all, TriStem’s experience sets us above and beyond our competitors. With over 100 years combined experience auditing utility bills, our staff can identify a wide range of errors that other utility audit companies and software programs miss. Many companies are adding utility bill audits to expand their services. In contrast, utility bill audits have always been and will always be our specialty.

Our Vision

TriStem will create solutions that empower consumers to take control of their utility costs. Investing in relationships and knowledge, we will grow a team dedicated to understanding the unique energy needs of our clients, helping them identify and achieve efficiency and financial goals, while exceeding the expectations of all our stakeholders. 

Our Mission

Our mission is to bring peace of mind to each client – you are entitled to the security of knowing that you have not paid and will not pay more than necessary for your utility services. Deregulation empowers consumers while also leaving them at greater risks. For that reason, TriStem is committed to the highest level of professionalism and integrity while conducting its audits and helping clients understand their utility bills.
