"Tri-Stem has been one of the best things that has happened to the City of Brownwood in a long time. They have helped us to recover over-billings in electricity and communication charges and savings going forward that were very significant.  They have been very professional, diligent and hard-working.  We could not be more pleased with our relationship."
Walter Middleton, Finance Director
City of Brownwood
"During this engagement the City has found TriStem to be a highly reputable company.  TriStem’s staff possesses a broad knowledge of utility operations, rates, pricing and billing practices. . . . Thus far, the City has been issued two large refund checks with other refunds pending.  We now pay less for electricity today than in the past. Of course, the true beneficiaries of TriStem’s work are the citizens of St. Louis."
Joseph K. Kuss, P.E., Deputy City Engineer
City of St. Louis
"Thanks for the excellent communication and follow-up. Bureaucracies have their rules and they usually serve to daunt someone to the point they give up. You haven't and we are so grateful."
Susan Cowley
Talitha Koum Institute
"As a result of TriStem’s audit the Department received refunds from the utility provider of $193,228.00.  In addition, the correction of the billing errors will now save the Department $72,460.00 per year . . . We were pleased to receive the refund with no up-front cost to us . . . We would not have been able to identify these billing errors without TriStem’s help.  I was very pleased with and recommend the service TriStem provides."
Cherie Randall, Construction Manager
Arizona Department of Corrections
“I would highly recommend TriStem as a potential business partner.  We found them to be a professional organization at all levels along with a highly skilled auditing staff. . . . They were successful in obtaining refunds and credits for the Postal Service of approximately $3.8 million. . . . you will not be disappointed in their service nor the results.”
Jeffrey A. Kaufman, Contracting Officer
United States Postal Service

City of New Orleans

This was a very unusual case, to say the least. There were serious billing issues including street light overcharges and maintenance not done on some of the 54,000 street lights in the City.
As a result of TriStem’s work, the City of New Orleans recovered $15 million over a 10 year span, primarily in street lighting and maintenance overcharges.
The City of New Orleans continues to benefit on a monthly basis from TriStem’s work. At the conclusion of the audit, the City was saving over $500,000 annually, and all of it’s accounts were being billed at the proper rate schedules. Faulty meters were replaced, and the City obtained the first detailed inventory of street and highway lighting in more than 20 years. Also as a result of TriStem’s work, the utility company agreed to bring street light maintenance up to an acceptable standard.


Welcome to Fabulous Las Vegas Nevada Signage

City of Las Vegas

TriStem’s work for the City of Las Vegas commenced in November 2007. The audit scope covered approximately 3,000 electric accounts with $255,000 spent monthly on street lights. The review included current and historical billing records, utility providers’ rates and tariffs, Nevada Administrative Code and Nevada Revised Statues’ provisions applicable to utility billing, and various facility records provided by the City.
On site comparisons of the utility provider’s inventory to the lights on the street revealed a 53% error rate on billing for unmetered lights. TriStem also found 41 metered lighting accounts had been overbilled every month for at least 6 years, resulting in a $252,582 refund to the City. Negotiations are on-going for unmetered lighting errors, estimated at $200,000+.
