Emergency Diesel ATS Path to GT
Your emergency diesels depend on automatic transfer switches that must move load in seconds when the utility drops. You exercise them, log the times and fix the slow ones. When gas turbines join your critical power plan, the transfer and synchronising logic changes, and an ATS scheme built for diesels may not suit turbine start times or sync rules.
If the logic is wrong, you risk a failed transfer, an out-of-phase close that damages equipment, or a dark facility during an outage. For critical loads, that is downtime you cannot explain away.
USP&E Helps You Carry ATS Discipline into Turbine Critical Power
We understand that your reputation rides on the few seconds after the utility fails. USP&E has delivered 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, and our 400+ engineers and project managers design, commission and operate critical power systems where transfer logic and turbine controls must work as one. We work under ISO 9001 and ISO 45001 certified systems with FCPA and OFAC controls. USP&E is a full-service EPC and O&M contractor, not a broker.
Know Exactly How Your ATS Fleet Behaves
Log transfer times, retransfer times, failure modes and exercise results for every ATS. Note which switches are open transition, closed transition or delayed transition, and which loads each one carries. Many sites find switches with settings nobody can explain and test records that stopped years ago.
Look at failure history honestly. A switch that sticks once a year in testing will stick during a real outage sooner or later. Fix or replace it before turbines are added to the picture.
Check how your ATS exercise routine loads the diesels. Many sites exercise switches with little or no load, which proves the switch moves but not that the generator accepts the load. Pair your transfer tests with real load where you can, and record generator response alongside switch timing so you see the whole chain.
Design Turbine Transfer and Sync Paths Separately
Map which transfer and synchronising paths your gas turbine generators will share or replace. Turbines usually take longer to reach rated speed than standby diesels, so they often run continuously or in standby with diesels covering the first seconds. Your logic must reflect that.
Write separate turbine sync-check and load-acceptance scripts beside your diesel ATS settings. Closed-transition transfers and paralleling need proper sync-check relays, correct phase and voltage windows and clear interlocks so nothing closes out of phase.
Test fail-safe behaviour. Ask what happens when a control signal is lost, a breaker fails to close or a turbine trips during transfer. Each answer should be a designed response, not a surprise.
Cover the Upgrade and Plan for Growth
Quarantine any ATS path that fails timing or fail-safe tests before turbines rely on it. During upgrades, plan cover with natural gas engines/stations or a remanufactured GE Frame 6B, and keep verified used/new gas turbines in mind for longer works.
If your facility is moving towards data-centre or compute load, design the transfer scheme for that future. AI gas turbines, hyperscale generators and gas turbines for compute, including the New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA, need transfer and sync logic that one hyperscale EPC/O&M team can test and maintain.
Local Teams Near Your Emergency Power Site
Data-centre schedules are won or lost in permitting, gas supply and interconnection, so USP&E puts its US offices first. Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) give you two US bases for engineering reviews, procurement follow-up and site visits, and both teams work your emergency diesel fleet transition alongside you rather than from a sales desk.
Behind them, London (162-168 Regent Street) handles structuring, bonding and finance; Johannesburg (22 Kildoon Rd, Bryanston) owns engineering and project controls for standby diesel fleets, ATS upgrades and AI gas turbines; Cape Town (31 Brickfield Road, Woodstock) supports design and commissioning; and Wuxi, China (No. 1, Ningzhou Road, Wuxi) manages China manufacturing and supply-chain follow-up.
For ATS and transfer upgrades, Colorado Springs and Knoxville engineers can review your switch settings and test records on site, while Cape Town supports O&M crews for the transition. Regions served: USA | AFRICA | UK | UAE | CHINA. That network stands behind 150+ power projects in 45+ countries and 25,000 MW contracted since 2002, run under ISO 9001 and ISO 45001 certified systems.
Proof from Recent Emergency Power Projects
You want proof that USP&E has delivered critical power where transfer and sync logic had to work first time. These projects show it.
- USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers.
- Kinross Gold, Tasiast, Mauritania: USP&E supplied and installed a Caterpillar backup power station of low-hour Cat 3516B gensets with new switchgear, on time and on budget. Read the case study.
- Zondereinde platinum mine, South Africa: USP&E supplied, packaged and serviced six zero-hour surplus Wabtec GE16V250 gensets, giving the mine 25 MW of base-load power through Eskom load shedding. Read the case study.
HowTo: Carry ATS Discipline into GT
Your 3-step plan: 1. Share ATS settings, test records and your critical power single-line under NDA. 2. Receive transfer and sync scripts, fail-safe tests and a cover plan. 3. Test, commission and run the scheme under accountable O&M.
- Log ATS transfer times, fail modes and exercise results for every emergency diesel.
- Map which transfer and sync paths gas turbine generators will share or replace.
- Write separate GT sync-check and load-accept scripts beside diesel ATS settings.
- Quarantine ATS paths that fail timing or fail-safe tests before turbines rely on them.
- Plan cover with natural gas engines/stations or a remanufactured GE Frame 6B during ATS upgrades.
- Trend transfer evidence after turbines join under one O&M owner.

FAQ: Emergency Diesel ATS Path to GT
Why can turbines not simply replace diesels on an existing ATS?
USP&E finds turbines usually take longer than standby diesels to reach rated speed, and closed transitions need proper sync checks. An ATS scheme built for diesels may not suit those times or rules. Your logic must be redesigned so turbines and diesels each do what they do best.
What should you log about your ATS fleet?
USP&E logs transfer and retransfer times, transition type, failure modes, exercise results and connected loads for every switch. That record shows which switches are slow, sticky or set without reason. You fix those before turbines join the critical power scheme.
How do you prevent an out-of-phase close?
USP&E specifies sync-check relays with correct phase angle, frequency and voltage windows, plus interlocks that block closing outside them. You test the logic with the real breakers. An out-of-phase close can damage generators and switchgear, so this check is never skipped.
What fail-safe tests should you run?
USP&E tests lost control signals, failed breaker closes and a turbine trip during transfer. Each case should lead to a designed, documented response. If your team cannot say what happens in each case, the scheme is not ready for critical load.
Where are USP&E’s offices for critical power transfer projects?
USP&E leads critical power transfer work from Colorado Springs and Knoxville, close to US facilities and switchgear teams. London structures contracts and finance, Johannesburg and Cape Town add field O&M depth, and Wuxi supports China supply chain and manufacturing. Every office works from the same project file.
Has USP&E delivered critical power with turbines before?
USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers. Public case studies also include Kinross and NEOM work with accountable EPC and O&M. You can read each case study and judge the evidence yourself.
Is USP&E a broker for ATS and generator equipment?
USP&E is not a broker. USP&E is a full-service EPC and O&M contractor that engineers, supplies, builds, commissions and operates power plants with its own engineers and project managers, so the team that designs your transfer logic also tests and runs it. You deal with one accountable team from first review to O&M.
How fast can USP&E respond to an ATS path review?
USP&E can start reviewing your ATS settings, test records and single-line as soon as you share them under NDA. Engineers flag failed or unexplained switches first, then issue the transfer and sync scripts and cover plan, with timing set by data quality and site access.
