A poor installation creates risks that stay hidden until an outage: a set that overheats in a cramped room, exhaust that drifts into air intakes, a transfer switch wired to the wrong loads, or a permit refused at the final inspection. Any of these leaves the building without backup, adds cost and pushes the handover back.
Installation Planned by Power Engineers
We know you need the job done safely, on time and right the first time. USP&E has delivered 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, from single emergency sets to complete power stations. Our systems are ISO 9001 and ISO 45001 certified. USP&E is a full-service EPC and O&M contractor, not a broker.
Here is how we approach an emergency generator installation, in the order the decisions need to be made.
Survey the Site and Size the Set
Start with the loads the generator must carry. List them, separate life-safety and critical loads from loads that can wait, and size the set for the starting demands of motors and other heavy equipment. An undersized set trips; an oversized one runs too lightly and suffers for it. If you expect the building to grow, say so now, because it is far cheaper to leave space and cable capacity than to rebuild the installation later.
Then survey the site. Where will the set sit, indoors or outdoors? How will it be delivered and lifted into place? Where will fuel be stored, and where can exhaust and hot air go safely? Check noise limits at the boundary and the distance to windows and air intakes. Your neighbours, your planning authority and your own staff will all notice a set placed in the wrong spot.
Foundations, Fuel, Air and Exhaust
A generator needs a level foundation sized for its weight and vibration, with isolation where noise or structure demands it. Outdoor sets need an enclosure suited to the climate; indoor sets need a room with enough air for combustion and cooling. If your room is tight, ask for a heat calculation before you sign off the layout, because overheating is one of the most common faults we find on site.
Plan fuel storage for the runtime you need and the local fire and environmental rules, including containment. Route exhaust away from people and intakes, with the right silencer for your noise limit. Our emission standards guide explains the rules that may shape the engine and exhaust choice.
Transfer Switch, Controls and Wiring
The automatic transfer switch is the heart of an emergency system. It senses the grid failure, starts the generator and moves the loads across. Size it for your supply, choose the right transition type and make sure it is wired to the correct loads. Our transfer switch specification guide walks through the choices.
Connect alarms and remote monitoring so a fault is seen as soon as it happens. Label everything clearly, so whoever responds during an outage knows what they are looking at. Train your own staff on the basic checks, so you are not waiting on a call-out to confirm the set has started.
Permits, Commissioning and Handover
Apply for building, electrical and air permits early, since they often set the pace of the project. When the installation is complete, commission it properly: a full load bank test, a real transfer test with the building load, alarm checks and a record of the results.
Hand over with drawings, manuals and a maintenance plan. If you need power before the permanent set is ready, temporary units can be arranged, and for larger sites we also deliver natural gas engines/stations, used/new gas turbines, gas turbine generators and a remanufactured GE Frame 6B. Data centres can use our hyperscale EPC/O&M for AI gas turbines, hyperscale generators, gas turbines for compute and New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA.

USP&E Offices Serving Emergency Power Buyers
You should not have to explain your load profile three times. For your emergency diesel fleet transition, USP&E links one accountable team across its offices, starting in the US: Colorado Springs (1755 Telstar Dr, Suite 300) and Knoxville (800 S Gay St, Suite 700) for US-side engineering, site walks and equipment follow-up.
London (162-168 Regent Street) sets up commercial structure and finance, Johannesburg (22 Kildoon Rd, Bryanston) leads design, project controls and quality for standby diesel fleets, ATS upgrades and AI gas turbines, Cape Town (31 Brickfield Road, Woodstock) adds engineering depth, and Wuxi, China (No. 1, Ningzhou Road, Wuxi) expedites switchgear, transformers and balance-of-plant from Chinese manufacturers.
Colorado Springs and Knoxville manage installations in the USA, Johannesburg and Cape Town handle African sites, and London and Wuxi support contracts and equipment supply. Regions served: USA | AFRICA | UK | UAE | CHINA. With 25,000 MW contracted since 2002 across 150+ power projects in 45+ countries, USP&E is ISO 9001 and ISO 45001 certified.
What USP&E Has Delivered for Emergency Power Buyers
Installation quality shows when the grid fails. These projects show the backup and prime power USP&E has installed.
- USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers.
- A giga-project developer in the Middle East: USP&E supplied three zero-hour Siemens SGT-400 gas turbines as the single technical and commercial interface.
- A gold mine in West Africa: USP&E rebuilt more than 80 MW of Caterpillar CM32 engines and added 24 MW of new zero-hour capacity, delivering a 104 MW station with 300% greater reliability and availability than previously recorded at site. Read the case study.
Steps in an Emergency Generator Installation
Your 3-step plan: 1. Share your loads, site plan and timing. 2. Get a sized set, layout and permit plan. 3. Install, commission and hand over with one team.
- Survey the site, loads and access route.
- Choose the location, foundation and exhaust path.
- Size the cables, fuel system and transfer switch.
- Get permits and utility approvals in place.
- Install, connect and inspect every system.
- Commission under load and hand over with training.

FAQ: Emergency Generator Installation, Step by Step
What are the steps in emergency generator installation?
USP&E follows a clear sequence: load assessment and sizing, site survey, foundation and enclosure, fuel storage, air and exhaust routing, transfer switch and wiring, permits, then commissioning with a load bank and a real transfer test. Handover includes drawings, manuals and a maintenance plan.
How do I size an emergency generator?
USP&E sizes emergency generators from a list of the loads they must carry, separating life-safety and critical loads from others. Motor starting demand often drives the size. A set that is too small trips, while a set that is too large runs lightly and wears poorly.
Where should an emergency generator be placed?
USP&E places emergency sets where they can be delivered and serviced, with enough air for cooling and combustion, exhaust routed away from windows and intakes, and noise kept within limits. Fuel storage, flood risk and access for refuelling also shape the location.
What permits does an emergency generator need?
USP&E usually plans for building, electrical and air permits, and sometimes fire and environmental approvals for fuel storage. Requirements vary by location, so check local rules early. Permits often set the pace of an installation more than the equipment does.
Which USP&E offices manage generator installations?
USP&E runs emergency generator installations in the USA from its Colorado Springs and Knoxville offices, and across Africa from Johannesburg and Cape Town. London looks after contracts and finance. Wuxi helps when sets, enclosures or switchgear come from China, so the site team receives the right kit on time.
What installations has USP&E delivered?
USP&E has delivered 150+ power projects in 45+ countries. Examples include a backup station of low-hour Cat 3516B gensets with new switchgear at a gold mine in North-West Africa, installed on time and on budget, alongside larger prime power stations.
Is USP&E a broker for emergency generators?
USP&E is not a broker. As a contractor for EPC and O&M work, USP&E has its own engineers to size the set, prepare the site, fit it and commission it. After handover they can keep servicing it, so the installer and the maintainer are the same accountable company.
How soon can USP&E start an installation?
USP&E can begin with a site survey and load review as soon as you share your plans. Permits and equipment lead times then set the programme, and engineers identify those early so you know when your emergency power will be ready.
Install It Once, Install It Right
Size from real loads, plan the site and commission properly, and your emergency generator will protect your building. Rush the installation, and the fault appears in the outage. USP&E will help you install backup power that works.
