If you do not know your critical path, you manage the wrong things. Effort goes to tasks with plenty of float while a transformer order, a gas connection approval or a switchyard design slips quietly. The result is delay to first power, idle buildings full of servers that cannot run, penalties in your customer contracts and the risk of expensive acceleration late in the job.
USP&E Helps You Focus on What Moves First Power
We know you are judged on the date power reaches the data halls, not on how many tasks are green. USP&E has delivered 150+ power projects in 45+ countries, with 25,000 MW contracted since 2002, and our 400+ engineers and project managers plan, build and commission on-site power plants where the schedule is the main risk. Our systems are ISO 9001 and ISO 45001 certified, and every deal runs under FCPA and OFAC controls. USP&E is a full-service EPC and O&M contractor, not a broker.
You do not need a bigger schedule. You need a clear chain of linked activities from contract to first power, early action on the long-lead items, and a weekly review that keeps the critical path honest.
Map Every Dependency from Contract to First Power
Start by listing every activity needed for first power, and for each one write down what it depends on. A turbine cannot be set until its foundation is cured. The foundation needs the geotechnical report and the final vendor loads. The switchyard needs the grid connection agreement and the protection design. Written this way, the schedule becomes a network rather than a list.
Include the work that sits outside the fence: permits, gas pipeline and metering, grid connection and the network operator’s own works. These are often the longest chains, and they are the ones a campus team controls least. Put them in the same schedule with named people responsible, not in a separate tracker that nobody reads alongside the construction plan.
Mark the long-lead equipment clearly: turbines, generator step-up transformers, medium-voltage switchgear, gas compressors and control systems. Their delivery dates anchor everything downstream. A team that has delivered EPC delivery for on-site power plants before will know which of these items usually drive the date.
Find the Critical Path and Protect the Float
The critical path is the longest chain of linked activities. Any delay on it delays first power by the same amount. Find it with your scheduling tool, then check it by hand: does the logic make sense, are durations realistic, and are there missing links that hide a longer chain? A schedule with missing logic will show a false critical path.
Look at the near-critical paths as well. A chain with little float can become critical after one late delivery. List the top risks on the critical and near-critical paths, give each one a person and an action, and decide where you can buy time: earlier orders, parallel work, pre-assembly off site or a temporary power solution.
Do not spend float you do not own. Float on a contractor’s activity is shared by the whole project. Agree how float is used in your contracts, so no single party consumes it and leaves the rest of the job exposed. Our data centre power programmes page explains how one accountable contractor makes this easier.
Review Weekly and Act on the Few Items That Matter
Review the critical path every week with the people who own the activities on it. Update progress with facts, not percentages guessed in a meeting. When an activity slips, re-run the schedule and see whether the critical path has moved. Act on the items that drive first power and leave the rest to normal site management.
Plan commissioning as part of the critical path, not as a block at the end. Energisation of the switchyard, first fire of the turbines, grid synchronisation and load testing all depend on systems being complete in the right order. A commissioning sequence written early helps the construction teams finish systems in that order.
Think about phasing too. Campuses that need power early may start with temporary units or a remanufactured GE Frame 6B, then add gas turbine generators, used/new gas turbines or natural gas engines/stations in blocks. Under hyperscale EPC/O&M, AI gas turbines, hyperscale generators and gas turbines for compute are scheduled as repeatable blocks, which is how the New USP&E FX-45 45MW Modular Gas Turbine for the Hyperscale Data Center sector in the USA is offered, with an FX-45 package overview for planning. Our sister site covers generator choices for compute campuses.
Local Teams Near Your Data Centre Campus 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 campus gas reception and GT build 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 gas reception skids, gas turbine generators and electrical yards; 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 campus power schedules, Colorado Springs and Knoxville planners work in your time zone on US campuses, and London supports contract terms that govern float and delay. 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.
What USP&E Has Delivered for Data Centre Campus Buyers

- USP&E has refurbished seven GE Frame 6B gas turbines to zero hours in-house for major US hyperscale data-centre developers.
- MAN redeployment, Iraq: USP&E moved a stranded 32 MW MAN plant, plus two surplus MAN generators, across four countries to an industrial buyer facing 12 to 18 month lead times for new engines. Read the case study.
- NEOM, Saudi Arabia: USP&E supplied three zero-hour Siemens SGT-400 gas turbines as the single technical and commercial interface, and the client reported savings of over $10 million. Read the case study.
HowTo: Find and Manage the Critical Path of a Campus GT Build
Your 3-step plan: 1. Share your campus schedule and long-lead equipment list. 2. Receive a critical path review with the top risks and actions. 3. Build, commission and run the plant with one accountable team.
- List every activity from contract to first power, with what each depends on.
- Mark the long-lead items such as turbines, transformers and switchgear.
- Link permits, gas supply and grid works into the same schedule.
- Find the longest chain of linked activities: that is your critical path.
- Act first on the critical items and protect the float on near-critical ones.
- Review the critical path every week and update it when anything changes.

FAQ: Campus Power Plant Critical Path for GT Builds
What is the critical path of a campus power plant build?
USP&E defines it as the longest chain of linked activities from contract to first power. Any delay on that chain delays first power by the same amount. It usually runs through long-lead equipment, permits, gas supply, grid works and commissioning rather than through general building work.
Which items usually drive the date of first power?
USP&E most often sees turbines, generator step-up transformers, medium-voltage switchgear, the gas connection and the grid connection drive the date. Permits and network operator works are frequent drivers too, because the campus team has the least control over them and they start early.
Why can a schedule show the wrong critical path?
USP&E finds that missing logic links, unrealistic durations and activities tracked outside the main schedule hide the real critical path. Checking the logic by hand and putting permits, gas and grid works in the same schedule usually reveals a longer chain.
How should float be managed on a campus power build?
USP&E treats float as shared by the whole project, not owned by one contractor. Contracts should say how it is used, so no party consumes it and leaves the rest exposed. Protecting float on near-critical paths keeps one late delivery from moving first power.
Where are USP&E’s offices for data centre campus builds?
USP&E supports US campus builds from Colorado Springs and Knoxville, with planners and engineers in US time zones. London supports contracts and finance, Johannesburg and Cape Town add engineering depth, and Wuxi follows up switchgear and other equipment made in China for your campus.
Has USP&E delivered power for data centre developers 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 three zero-hour Siemens SGT-400 turbines supplied for NEOM in Saudi Arabia as the single technical and commercial interface.
Is USP&E a broker for campus power projects?
USP&E is not a broker. USP&E plans, builds, commissions and maintains power plants with its own engineers, so the team that reviews your critical path is the same team that delivers the plant and answers for the date of first power.
How fast can USP&E review my campus power schedule?
USP&E can start reviewing your schedule and long-lead list as soon as you share them. Engineers check the logic and flag the critical and near-critical items first, so you know quickly where to act and where time can still be recovered.
Manage the Path, Meet the Date
Know your critical path and you spend effort where it moves first power. Miss it and the date slips while everything looks green. USP&E will help you plan, build and commission your campus power plant with confidence.
