Emergency Fleet ATS Path to GT
Your emergency diesel fleet already owns the ATS rooms, the exercise schedule and the life-safety transfer paths. Now firm gas turbine capacity is joining the yard, and every automatic transfer switch has to know which source to trust and when.
If transfer logic is not redesigned carefully, an ATS may transfer to a source that is not ready, hunt between sources or delay life-safety loads. That means failed transfers, outages in critical areas and compliance problems that inspectors will find. The risk is highest exactly when everything else has already gone wrong.
USP&E Helps You Keep Transfers Clear and Safe
We know emergency power teams are accountable for life-safety loads that must transfer every time. Since 2002 USP&E has built 150+ power stations and supplied about 25 000 MW across 85+ countries, with 35+ completed utility-scale projects and 18 live projects in 11 countries. Our 400+ engineers and project managers design transfer schemes, standby fleets and turbines together. USP&E is a full-service EPC and O&M contractor, not a broker.
Protect Diesel Start and Transfer Paths First
List every ATS on your site with its loads, priority level, current sources and timing settings. Separate your life-safety, legally required standby and optional standby loads, because codes treat them differently. Your emergency diesels and their transfer paths for life-safety loads should remain independent of the turbine plant wherever codes require it.
Then define your source priority. When the utility fails, which source should each ATS seek first: running gas turbine generators, standby diesels or a combination? How long should it wait, and what happens if the preferred source is overloaded? Write those rules down before anyone touches a setting on your switches.
Check your timing chain end to end. Engine start times, turbine availability, ATS delays and load-step limits must add up to transfer times that meet your code requirements and your own expectations.
Bridge With a Remanufactured GE Frame 6B While ATS Capacity Matures
A remanufactured GE Frame 6B can add firm island capacity while your ATS redesign is completed. Connect it to optional or legally required standby loads first, leaving life-safety transfers on the proven diesel path until the new logic is tested. Check inspection records and controls status before it ships.
Natural gas engines/stations start quickly and can share standby duty. Comparing used/new gas turbines and engines on start time, step load and fuel helps you assign the right source to each load class.
Upgrade your ATS controllers where needed. Older units may not support multiple sources, closed-transition transfers or remote monitoring, and replacing them during the redesign avoids a second round of shutdowns.
Plan for AI Gas Turbines and Hyperscale Generators on the ATS Horizon
As AI gas turbines, hyperscale generators and gas turbines for compute join a site, ATS schemes grow more complex. Plan your source priorities and switchgear for the end state, so each new block fits a clear transfer hierarchy rather than adding exceptions.
The planning reference for later blocks is modular FX-45 OCGT 45MW / CCGT 108MW 2×1, for 50 Hz and 60 Hz, with capacity slots from 2028. USP&E carries transfer logic, standby fleets and turbines into hyperscale EPC/O&M, with your island rules, exercise schedules and mixed-fleet procedures tested and recorded.
Global Offices Behind Your Emergency Power Programme
Your team wants answers in its own time zone. USP&E’s offices in Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) lead your emergency diesel fleet transition conversations in the US, from the first data request to the site visit, so questions about fuel, interconnection and delivery are answered by people who can be on site.
The wider network carries the heavy lifting for standby diesel fleets, ATS upgrades and AI gas turbines: London (162-168 Regent Street) for structuring and finance, Johannesburg (22 Kildoon Rd, Bryanston) for engineering and project controls, Cape Town (31 Brickfield Road, Woodstock) for design and commissioning support, and Wuxi, China (No. 1, Ningzhou Road, Wuxi) for China supply chain and manufacturing.
For an emergency fleet adding turbines, that means Colorado Springs and Knoxville engineers who can review your ATS rooms with your inspectors, with Cape Town supporting transfer testing at commissioning. Regions served: USA | AFRICA | UK | UAE | CHINA. USP&E’s reach covers 85+ countries guided, 35+ completed utility-scale projects and 18 live projects in 11 countries, and the company is ISO 9001 and ISO 45001 certified.

HowTo: Build the equipment and delivery path
Your 3-step plan: 1. Share your ATS list, load classes and turbine plans under NDA. 2. Get a transfer-logic redesign and turbine option set with EPC and O&M scope. 3. Test every transfer, commission and operate with accountable O&M.
- Separate true emergency loads from continuous and compute-adjacent duties that may migrate onto GT capacity behind redesigned ATS logic.
- Compare emergency diesel retention, natural gas engines/stations, a remanufactured GE Frame 6B, and verified used/new gas turbines against that ATS and duty matrix.
- Review candidates at the central inventory hub and request records, inspection findings, controls status, and logistics dimensions.
- Reserve civil and electrical interfaces for modular FX-45 OCGT 45MW / CCGT 108MW 2×1, 50/60 Hz, with capacity slots from 2028.
- Rewrite ATS, black-start, island transfer, exercise, and O&M procedures for the mixed fleet with named leads.
- Complete permits, funding, fuel agreements, and commissioning rehearsals before final equipment selection.

FAQ: Emergency Fleet ATS Path to GT
Why must ATS logic change when gas turbines join an emergency fleet?
USP&E redesigns ATS logic because each switch must know which source to seek first, how long to wait and what to do if that source is not ready. Without clear rules, transfers can fail, hunt between sources or delay life-safety loads.
Should life-safety loads transfer to gas turbines?
USP&E keeps life-safety transfers on paths that meet your code requirements, often the proven emergency diesel path, until any new arrangement is fully tested and approved. Turbines typically serve legally required and optional standby loads first, under a clearly documented source priority.
Where does a remanufactured GE Frame 6B fit in a transfer scheme?
USP&E usually connects a remanufactured GE Frame 6B to optional or legally required standby loads first, leaving life-safety transfers on the diesel path. Once new logic is tested, its role can expand, and inspection records and controls status are verified before shipment.
Which USP&E offices support emergency power projects?
USP&E supports US emergency power projects from Colorado Springs and Knoxville, where engineers work with site teams and inspectors. Johannesburg leads engineering and project controls, Cape Town adds design and commissioning, London covers finance, and Wuxi supports China-made switchgear and ATS hardware.
Has USP&E delivered critical power projects before?
USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers. USP&E also supplied and installed a Caterpillar backup power station with new switchgear for Kinross Gold at Tasiast in Mauritania, on time and on budget.
Is USP&E a broker for emergency generators?
USP&E is not a broker. USP&E is a full-service EPC and O&M contractor that redesigns transfer logic, supplies and installs turbines, standby units and switchgear, commissions every transfer and operates the plant, so one accountable team owns your emergency power.
How fast can USP&E respond to an ATS review request?
USP&E can begin as soon as you share your ATS list, load classes and turbine plans. US-based engineers review source priorities and timing first, then schedule a site walkdown, so timing depends mainly on the quality of your documentation and how soon your site can host us.
How should transfers be tested after the redesign?
USP&E tests every ATS under the new logic at commissioning, covering utility failure, source unavailability and return to normal. Transfer times are recorded against code requirements, and exercises continue on your regular schedule, so each switch is proven rather than assumed.
Keep Every Transfer Clear When It Matters Most
Redesign transfer logic properly and your turbines add firm capacity while life-safety loads still transfer every time. Skip it and one confused ATS could fail on the worst day. USP&E will help you add generation without compromising your emergency paths.
