At our Bayou Cove plant with 4× 7EA DLN 1.0 in Peaking Service we had a situation with our Megawatt (MW) transducers. One of the two MW transducers connected to each GE Mark V Turbine Control Panel occasionally froze (always the same brand). Due to the “Hi-select” block, the frozen MW transducer caused the units to runback or trip. We consulted with your Chief Engineer, Mr. Abel Rochwarger, and he offered the following solution:
- Detect the frozen transducer with quite a, it is fair to say, creative solution.
- Replace the “Hi Select” block with a more suitable one that will avoid the unit to runback or trip.
Because of the singularity of the issue, and the trust we developed over the years with GTC’s controls engineering capabilities, we agreed with the plan. The novel solution was implemented and successfully validated. This testimonial is to remark on the continuous support provided by the whole GTC Control Solutions Team with parts, repairs, service, EEPROM backup and care, always with timely responsiveness and a friendly approach. We do not let anybody “touch” our controls because we consider GTC Control Solutions more than a Trusted Advisor: you are part of our team.

“We needed upgraded parts for overnight delivery to avoid any outages. They were able to upgrade the resistors as requested and shipped overnight to us. We were impressed GTC’s prompt attention to request and fulfillment & it was a pleasure working with Bret Stevenson & Laura Connell.”
Sasha G. – Calpine-Bosque Energy Center
“Our GE Mark IV Card was not working and the units we had on shelf for backup did not work when installed. GTC had unit in stock and able to ship within hours so we could receive the next day to get up and running. They were very attentive to the immediate need and gave me fantastic service to help us get back running. William Evans and Laura Connell are great!”
Barb D. – Energy Center Dover
“There is a local lack of knowledge of older GE Speedtronic systems in our territory. We contacted GTC & established a service contract for spare parts and this proved to be so valuable. They have a depth of knowledge in the systems and support for repaired/remanufactured hardware. GTC’s professionalism made business a far simpler process.”
Ken S. – Synergy, Australia
“We were in desperate need for a large contactor for our GE EX2100e excitation system. Lead time through our normal sources was approximately 85 days. We made the call to GTC and spoke with Will. They had the complete refurbished unit in stock and Will personally drove after hours to our location to deliver the unit within a few hours. Needless to say, it’s hard to find customer service like that in today’s world. We are grateful for the service and knowledge that GTC has been able to provide us. We have also used them recently to source some no longer available RTP PLC cards as well. What they are not able to find new or refurbished, they are able to repair. Can’t say thank you enough for your assistance this year.”

“Laura Connell is Fantastic. The customer service she gives me is Top Shelf. She provides fast and accurate answers that allow me to direct my station it’s best results by shortening down time. Finding inventory and speaking with knowledgeable people who know how to deliver customer service, Laura was able to answer all my questions about Mark VI parts. One person can make or break a company. Laura Connell is a big reason I work with GTC!”
Craig F. – IHI Power Service Energy
I want to thank the team at GTC for their response and providing equipment for our LCI. Laura answered the phone, quickly looked up parts needed, and confirmed current quantity of items on the shelf ready to ship – all within the first three minutes. Once I explained the desire for quick delivery, I received a quote promptly, and the GTC technicians performed check outs of the cards ordered on that same day and got them out the door. Parts were delivered on site within approximately 24 hours of ordering them, installed, and worked as expected.

I just wanted to say thanks for the quick help on resolving the unplanned trip of our TG5 turbine generator at our West Monroe mill last month. You really helped minimize the downtime and cost to the mill by taking the time to answer some technical questions and assist our onsite technicians with their troubleshooting. Even though it only took a few minutes to answer the questions, It’s the quick responses to unplanned events that make a difference.
Richard – Graphic Packaging International
I wanted to thank you for the Awesome training that focused on the areas requested. The training and interaction with the team was really good, your knowledge and experience really gave a lot of insight into our system that helped the team a lot. We definitely are in a way better position to go into the run season and future on a plant knowledge and Mark V system than before for sure.
Again it was an absolute pleasure and a treat to meet you and I am very grateful for the plant side items you were able to guide the team thru to make the plant better and provide training along the way.

Gabriel – Martinez Refining Company
We were looking for a DS200TCEAG1A board that was apparently hard and rare to come by.
GTC had one cad in stock that could met our criteria. What impressed me most about GTC is their willingness to assist us with what we needed. Obviously, it being an emergency there was an expediting fee to get us to front of line, but we were made aware of this ahead of time.
Brian – Talen Energy
Thank you for all the support you provided us in getting our unit back available. We received the new TCCA board this morning and installed it. We had a communication issue to the HMI that was resolved by a reboot of the TMOS server.
Unit was tested and ran fine. Thanks again for all the help.
Robert – Lake Worth Beach Electric Utilities
GTC Control Systems was able to quickly provide us the with the parts needed when our Frame 5 GE Turbine went down unexpectedly. They were willing and able to assist us with all of our questions.
Mike – Indianola Municipal Utilities (IMU)
We experienced a power supply fault that damaged 11 Speedtronic cards. Hence, we reached out to GTC to see if they could help.GTC was able to supply us with replacement cards and accommodated us with short lead time for replacements. Being that is was a holiday weekend, GTC did their very best to accommodate us.The response time and availability of replacement parts for the GE Speedtronic control system and the personnel that assisted us once the call was made for assistance. Because of this, it allowed us to quickly request a quote for the item in question and in turn purchase it. GTC’s expedite services allowed us to receive most of the items the very next day.
Leo – E.F. Barrett Gas Turbines
Rushed procurement of a card/module for excitation control panel (151X1207CK02SA01 600/1000v GENAUX Module base) was needed. A replacement of this part was quickly needed. GTC’s team moved quickly to locate card in inventory, testing card, and quick turnaround time on shipping a new card. The team also worked with our procurement/planning department to pay for the card and set us up as a new customer. The fact that the part number showed up on a google search directly connected to GTC’s website was impressive. Because of this, it allowed us to quickly request a quote for the item in question and in turn purchase it. GTC’s expedite services allowed us to receive the item the very next day.
George – BP
We were in need for support for our Bently Nevada Controls Model 3500. With some digging, we came to a conclusion that the issue was faulty probes and proximeters. Therefore, we needed to look for support. GTC was very quick and diligent in providing us options to resolve our current issue. After several conference calls, GTC and our group agreed upon an action plan. The plan consisted of a Technician to be sent to the site to resolve the issue at hand. The whole action plan was organized quite efficiently. The knowledge that the technician had, not only did he help resolve the issues but he had found issues that we didn’t even know we had, then he fixed those issues and made recommendations for future issues, not only are we extremely satisfied with this company and technical support it seems that they will be a fixture at our plant for outages to come!
Stasiu – NAES, Empire Generating
Our unit was down and we needed the necessary boards in order to get it operational. With one phone call, not only did GTC confirm they had the correct boards we needed, but they also ensured me that they would have it to me next day. I had two representatives assisting and following up with me throughout the day to let me know the status of my order. I was impressed with the fast response and follow through. Even after our parts had arrived, the representatives contacted me to make sure we received them and if we needed anything else.
Dominick – Portside Energy LLC (Portside Energy Facility)
I have nothing but High praise for GTC’s services and products. Since we switched to GTC for all our MKIV and MKV needs I have not yet experienced getting a bad card back from the repair vendor. This was not the case with our previous vendor. I have also attended a GTC MKIV training class (taught by Able), which I found very valuable.
Concerning this recent call out. I really appreciated getting work with Able, I find him to be a wealth
of knowledge. He was persistent at methodically drilling down to find the problem and quick to deal
with unexpected complications as they arose in the process.
As for services that could be marketed to TVA? Upgraded or improvements to the 7EA excitation system. MK6 specific training. A presentation on Logic and instrument changes that can be made to improve reliability, performance or ease of operation.
As to who these could be marketed to? I’m not sure. Maybe an engineering manager. In general TVA’s current plant managers and Regional managers are not well versed in how control changes and upgrades impact reliability and operation / man power costs.

Turbine Controls & Excitation Group (TC&E) is often called on to provide control system parts along with our services and troubleshooting. For over 10 years, GTC has been our ideal supplier. GTC’s afterhours or weekend response and personal attention has supported TC&E in returning dozens of forced outages in hours instead of days. We are grateful for GTC’s commitment to quality and excellence.

I always enjoy Abel because (1) the technical depth will be excellent yet easily accessible, (2) I know he’ll say several things to make me laugh. You’ll have one of those within the first minute and then you have to wait for the nerd quiz!! If you are in the energy industry and do not follow him on LinkedIn, well, you should. If you need help on the fence in your backyard, and you like to make scratch pizzas, then you should call him (and I will join) and we’ll have that 3hr task done in less than two shifts. But you’ll laugh all the way through with us. I commend this webinar to you. Enjoy.
Tom – GE
We had a forced outage on one of our four GE 7EA units due to EX2000 issues at our CLECO Bayou Cove Power Station, in Jennings, Louisiana.
GTC, our supplier and trusted advisor for turbine control, excitation control, and HMI interface, provided remote support, before they mobilized to site on very short notice. Arriving on a Friday, they provided excellent troubleshooting support, returning the unit to service before the weekend was over.
GTC’s specialist, Mr. Jim Sessions, closely collaborated with our personnel during his stay.
Mr. Sessions, with GTC’s usual professionalism, goodwill and without a request from us, also installed specialized data acquisition equipment to further analyze the situation for two weeks after his demobilization.
Therefore, and because of the consistent quality of parts and services you provide to our company, we are pleased to extend this testimonial to GTC, authorizing you to distribute this testimonial and our contact information as a reference for your customers.

This month GTC Control Solutions successfully delivered a new Technical Support Service to update the Modbus communications between HMIs and our Foxboro DCS. GTC is our go-to supplier and trusted advisor for the Mark equipment and HMI interface, which we use to operate LM5000 turbines.
Due to the limitations imposed by the COVID-19 pandemic, and the urgency to implement the changes, we accepted the advice offered by GTC based on their experience and ability to carry out the job as a Remote Service.
GTC specialist, Mr. Abel Rochwarger, closely collaborated with our personnel and, in this case, with the Foxboro’s Service Representative. Abel delivered the required files on time and provided online support to install and commission the modifications. He also delivered the report detailing the proceedings with valuable recommendations.
To capture operational parameters of our turbines, these modifications save us time and will prevent transcription errors, ultimately improving the productivity of our Operations personnel.

Appreciation for technical support during trying times, the Martinez refinery performed a GTG major turnaround. The machine is a GE Frame 6B, it is operated/controlled utilizing the GE Mark V control platform (circa 1995).
Due to GE’s inability to support the obsolete Mark V control platform a couple years ago, we reviewed other support options. We chose to purchase Mark V controls components from GTC Control Solutions. They not only provided parts, but also remote technical support during these transactions.
Having experienced very positive knowledgeable support in the past, we decided to utilize GTC to accommodate the controls portion of the 2020 major outage.
Chief engineer, Abel Rochwarger, was scheduled to support the controls set up post TA. He was also commissioned to perform onsite Mark V training to site controls engineers. Due to restrictions and quarantines from COVID-19, we were unable to get Abel to the site. GTC offered full remote support of any and all TA controls needs. The turnaround went well and the controls components SRV, GCV, and IGV’s were all calibrated successfully.
Shortly after startup, the GTG experienced an intermittent failure of an exhaust thermocouple. During the phone consultation with Abel, it was pointed out we had a weakness in the Mark V exhaust spread trip logic. He provided start up technical assistance, expeditiously providing technical solutions minimizing any delays.
We cannot thank Abel and GTC Control Solutions enough for the flawless technical support provided over the last month. The Mark V configuration is complex and always seems to present new challenges.
Having a GTG and Mark V system expert such as Abel makes a huge difference.
Money well spent to minimize start up delay, not to mention a discounted cost for remote support while complying with the worldwide pandemic restrictions.
Thank you Abel and GTC Control Solutions!

Our plant blew a hardware stage on our LCI. Although it was very short notice, we heard back from GTC within 10 minutes and were given a quote for the items we needed. They had everything but one item, but it was quickly sourced from a distribution center in Florida and hand-delivered to us by a GTC representative before the first package had even arrived.
We had major concerns whether our plant would continue to receive the support we need. GTC exceeded our expectations with the responsive, professional and personalized services they demonstrated.
Thank you GTC – TJ, Sam, and Roger!
Kristopher – City of Tallahassee
GTC continues to provide high quality support in terms of spare parts, repairs, and field service for our Speedtronic Mark V systems.
Our relationship with GTC began in 2015 with an emergency request to perform special sequence modifications, which allowed us to successfully complete the Grid Compliance. In one instance, the team at GTC volunteered a significant credit acknowledging an overcharge due to a mismatch between the requested repair scope and the actual work performed, all without needing a formal claim from Proelectrica.
We conduct a yearly supplier review, and, to date, GTC has consistently maintained the level of commitment, flexibility and quality required by our strict vetting processes. The situation was opportunely informed to GTC by our Sourcing Department.
We expect to continue this fruitful relationship with GTC Control Solutions for years to come.

Qatalum has worked with GTC Control Solutions for the past 2 years now, and have entered into a Frame Agreement for the repair of GE Mark VIe, EX2100, LS2100, and Bently Nevada hardware including I/O Packs, Terminal Boards, VME Boards, and TDI Cards.
The service provided by GTC is excellent and has added significant value to our supply chain and maintenance strategy. The quality of work has exceeded our expectations and benefitted our Operational Costs by cutting expenses in control maintenance.
Before entering into the Agreement, Qatalum was invited to GTC’s facility in New York to view the test and repair operations. GTC provided demonstrations of their GE Control Panel setup that was used to fully test packs and cards after repair and before supply.
GTC’s facility is impressive, as well as the technical knowledge of all their technicians and support staff.
We have continued to receive a fast turnaround, while receiving zero discrepancies or faults. In addition
to the repair of hardware, GTC provides technical support and advice for all aspects of the related Control Panels.
Qatalum highly recommends GTC Control Solutions to any plant operators that are seeking a cost effective and efficient alternative to purchasing replacement cards, many of which are obsolete and no longer supported by the OEM.

For example, the Control System Health Check carried out on-site demonstrated the depth and quality of the field services offered. The final report was delivered in a timely manner, meeting our quality expectations in terms of presentation, depth, and accuracy. Regarding spare parts and repairs, GTC always demonstrates a candid and flexible approach, which is key to resolve the situations that arise in the course of doing international business.
We plan on continuing this fruitful relationship with GTC Control Solutions for years to come!

Due to their quality and price, GTC has become the preferred provider for maintaining Perennial Power’s GE Speedtronic Mark V Controls System.
For days we were having issues starting up one of our GE 7FA’s, so I called our GTC Engineer who was located on the other side of the globe. Without his laptop, he was able to walk our I&E Tech through the system, pinpointing the failed card. Once the card was installed, the unit successfully started.
We had asked about the cost and the GTC Engineer had said he was happy to help and there would be no charge.
