Why HMT?

Established in 1996, HMT provides a full range of high voltage engineering, testing, maintenance, and repair services. Our primary point of difference is simple; our personnel. We retain some of the most qualified and highly skilled Electrical Technicians and Electrical Project Engineers employed in the industry. The extensive experience that they possess relative to engineering, evaluating, testing, maintaining and repairing electrical power distribution equipment has effectively positioned HMT as an industry leader.

At HMT, we constantly strive to ensure that our Power Engineers and Electrical Technicians are trained to the optimum levels of proficiency within their respective areas of concentration. To that end, HMT has achieved Full Member Certification with the InterNational Electrical Testing Association (NETA). All of our technicians are NETA certified and our senior technicians have achieved Level 3 status.

Our technicians possess the experience necessary to perform the most advanced diagnostic testing, maintenance and repair service available in the industry. The depth and scope of our equipment inventory allows us to react and respond to multiple projects simultaneously while ensuring that each individual project is completed efficiently and accurately using the latest methods and best practices associated with electrical system testing, maintenance and repair.

Here's What Our Customers Say:

"I am writing on behalf of SNC-Lavalin Construtors Inc. and the Astoria Energy II Project. Now that we have reached the Commercial Operation of the Power Plant and the Astoria Annex Substation, I thought it would be appropriate to recognize and thank all of the members of HMT team who helped make this project such a success.

As you know, this was a very challenging project, not only due to the complex logistics, short schedule and interfacing with so many outside state/city/vendor entities. The members of HMT team demonstrated a level of professionalism and skill that enabled the project to be constructed and commissioned within a short schedule and delivered an end product that makes the Astoria Energy II Power Plant and the Astoria Annex Substation one of the finest in New York City.

HMT team members were called upon to work long hours in order for key systems to be ready in time for energization of the Astoria Annex Substation and commissioning of the Astoria Energy II Power Plant, and then provided vital support to our start-up team to bring the plant to COD. We have completed both substation and power plant now, and your members played a critical role in transitioning the power plant to a fully operational power plant selling power to NYPA. This included a large piece of unexpected work rebuilding our 345kV cables, finishing the check-out of the HMI system multiple times, assistance with power plant relaying and reconfirming our relay coordination after the event with the Utilities. We can't say enough how much we appreciate these efforts.

The success of the Astoria Energy II project and the Astoria Annex Substation is due in large part to the fact that HMT team and management worked towards a common goal through cooperation and respect for each other. When these types of relationships are formed, everyone benefits. Each and every HMT team member who worked on this site, or off-site, whether it was for 2 weeks or 1 1/2 years, should be proud of what they helped build here. Our thanks go out to all of you.”

“I would like to take this opportunity to express our appreciation from Brookfield Power’s Carr Street Generating Station, for the exceptional quality of service that has been provided to us by HMT in recent years.  Your commitment to supporting CSGS with your services and products continue to allow CCSGS to meet all of our operational, safety and business goals.

We truly hope that HMT and CSGS can continue to prosper do business for years to come.

Thanks for everything.  We look forward to working with you in the future.”

"I want to thank you and your team for a job well done. On the morning of Oct. 15th, one of our main 480v transformers failed. With your direction and innovative thinking we limited the outage to less than 24 hours. What could easily have been a few days was reduced to 24 hours by your planning and understanding of our facility. If there is a lesson learned here it is this; in the long and short run it pays to secure a firm with technical knowledge and expertise to perform the entire spectrum of work. It is my belief that had we not been working with you for many years the downtime of Oct. 15th would have been vastly extended. I ask you to let all who were here all night know how much I appreciate their efforts. Without your excellent planning, knowledge and work we would have been in a world of hurt. Again, thank you to the entire crew".


— A. Neil Newman, Climax Manufacturing

"I am writing to personally thank you for your efforts in response to our substation crisis of May 28th. Now that our utility has resumed somewhat "normal" operation, I have had time to reflect on the critical role you and your staff played in our crisis recovery and long term substation maintenance planning.

I am sure you recall the day of May 28, when you raced to Sherill in the morning, brought along your technicians and had the persistence (not to mention the physical strength) to work through the night well into May 29th. For the first day (or two) I am sincerely grateful. We accomplished an aggressive goal of restoring service to 100% of our customers. Your personal expertise was valued.

As we worked on permanent fixes to our substation, I was again impressed with your competent staff. Thanks to Jeff, Paul, Pete, and any others I missed. Those men demonstrated a high level of practical substation knowledge and conducted their work in a safe manner. I will not hesitate to utilize your services again for any type of substation work; I look forward to discussing future projects with you. Thanks again."


— Keith Pitman, PE, City of Sherrill

"When it comes to maintaining the electrical system at Cornell University, I've come to rely on HMT, Inc.

"On behalf of the employees of the Village Of Canajoharie Waste Water Treatment Plant, I would like to thank you for your technical assistance after the extensive flooding our plant suffered on June 28, 2006.

No one could have imagined the damage that our plant suffered and we are grateful that you were able to work with the plant staff to safely establish electrical service throughout the facility.  We also respect your ability to communicate with the staff while accessing electrical problems.

The problem within our facility was so enormous, but it did not hinder the fact that safety was your first priority, as it was ours.  This allowed our staff to understand step for step what was being energized electrically versus what was not. 

Again, thank you for helping us through this disaster.  Your efforts were tremendous and greatly appreciated."


— Jerry V. Ward, Assistant Supervisor
