Data center teams are being forced to make medium-voltage (MV) equipment decisions earlier. Switchgear, transformers, MV cable, and related electrical infrastructure can determine whether a project stays on schedule long before a site is ready for installation. If procurement waits for the traditional construction process to catch up, valuable schedule flexibility may already be gone.
That is one reason I see more data center owners evaluating OFCI, or Owner Furnished Contractor Installed. Under an OFCI model, the owner controls the equipment purchase and the contractor installs it. The owner has greater control over what is being purchased, when it is ordered, where it is allocated, what it costs, and when it needs to arrive.
But there is an important distinction: owner control does not have to mean owner managed.
Someone still has to manage manufacturers, submittals, engineering changes, production schedules, inspections, logistics, delivery dates, site readiness, testing, and commissioning. Chateau Energy’s program management is a major part of the work we do for data center clients. The owner retains visibility and control without having to build an internal team to chase every piece of medium voltage equipment from purchase order through energization.
That is where I think the OFCI model becomes much more valuable than simply buying MV equipment directly.
The first advantage of OFCI is the ability to separate critical medium voltage equipment procurement from the contractor’s purchasing schedule. That can allow the equipment process to begin earlier while design and construction continue moving forward.
In a traditional contractor-furnished model, equipment procurement can sit several steps downstream. Specifications have to move through design, contracting, buyout, and other activities before an order reaches the manufacturer. In a long-lead medium voltage equipment market, those months matter.
With OFCI, critical medium voltage equipment such as switchgear, transformers, and medium voltage cable can be identified earlier, technical requirements can be reviewed, and manufacturing capacity can be pursued based on the project’s energization requirements rather than waiting for the normal construction purchasing sequence.
This is also an area where an experienced equipment partner matters. Chateau works directly with medium voltage equipment manufacturers and maintains relationships across the market. Those relationships give us a better understanding of capabilities, production schedules, equipment alternatives, and where manufacturing opportunities may exist.
That does not mean every project jumps to the front of the line. It does mean we are not starting every MV equipment search cold. Relationships, purchasing volume, ongoing manufacturer communication, and visibility across multiple projects can help uncover options that may be difficult to see through a one-project-at-a-time purchasing process.
The objective is not simply to place a purchase order sooner. It is to secure the right MV equipment and protect the energization schedule while there are still options available.
OFCI shifts medium voltage equipment control to the data center owner, but the day-to-day management can be handled by an experienced program management team. For many data center developers, this distinction is critical.
Buying the MV equipment is only one piece of the process.
After the purchase order, there are submittals to manage, technical questions to resolve, manufacturer drawings to review, production milestones to track, factory testing to coordinate, logistics to plan, and delivery dates to match against actual site readiness.
Changes at one point can affect everything downstream.
Our role at Chateau Energy is to keep those pieces connected. We work between the owner, equipment manufacturers, engineering teams, electrical contractors, general contractors, utilities when required, and commissioning teams. We maintain visibility into where equipment stands and identify issues while there is still time to address them.
The owner should have more visibility through OFCI, not another administrative burden.
That means providing useful information to the owner: What has been approved? What is still outstanding? Is manufacturing on schedule? Has the required delivery date changed? Will the site be ready? Are there technical issues that could affect testing or commissioning?
The owner keeps control of the equipment strategy and the important decisions. The program management team handles the work required to keep that strategy moving. These are the initiatives we manage at Chateau Energy.
One of OFCI’s biggest advantages is that data centers have greater visibility into medium voltage equipment throughout its lifecycle, but visibility has to continue well beyond the purchase order.
A PO tells me MV equipment has been ordered. It does not tell me whether the project is protected. Read our blog: Securing MV Equipment Sooner is Only Part of Protecting Data Center Energization.
Submittals can stall, manufacturers can need clarification, and a single component issue can affect the entire production schedule. Meanwhile, the project schedule may keep moving even when the equipment schedule does not. Equipment can also arrive too early, too late, or before the site is ready to receive it.
That is why we manage medium voltage equipment against the energization plan rather than treating procurement as an isolated workstream.
For Chateau Energy, that can include specification verification, manufacturer coordination, submittal and design review, production tracking, factory testing management, quality assurance, logistics, delivery coordination, installation readiness, testing, and commissioning support.
The question throughout the process is not simply, “When does the equipment ship?”
It is, “Is the equipment schedule still aligned with when this data center needs power?”
OFCI becomes more powerful when data center owners can standardize medium voltage equipment across multiple projects, campuses, or regions. Standardization gives the program more options for forecasting, procurement, manufacturing, stocking, reallocation, maintenance, and future replacement.
That does not mean forcing identical MV equipment into every site. Utility requirements, system capacity, topology, fault current, project design, and local conditions still have to drive the technical solution.
The goal is to standardize where it makes sense: manufacturers, equipment families, ratings, interfaces, cable specifications, controls, documentation, and other repeatable elements.
Once that framework exists, we can look farther ahead.
Instead of asking what one project needs six months from now, the conversation becomes what the development program expects to need over the next several years. That allows the owner and Chateau Energy to forecast quantities, engage manufacturers earlier, discuss production capacity, and build procurement strategies around expected demand.
It also makes medium voltage equipment reallocation and stocking programs much more practical.
When medium voltage equipment and schedules are managed across multiple projects, OFCI can give an owner the ability to move medium voltage equipment to the data center project that needs it most.
That can become extremely valuable when construction priorities change.
We saw this on an AI data center project where critical medium voltage switchgear failed late in construction. Ordering replacement MV switchgear through a normal manufacturing cycle would not have supported the commissioning schedule.
Chateau Energy reviewed active switchgear orders across the developer’s other projects, compared production timing and site readiness, and identified equipment that could be reassigned without creating a new problem somewhere else. We then worked through the equipment and schedule implications of replacing that position within the broader program.
The switchgear was delivered, energized, and commissioned in less than one month.
The important lesson is not simply that MV equipment was moved quickly. The option existed because there was visibility across multiple medium voltage equipment orders and project schedules. That is the value of program management.
If every purchase is treated as an isolated transaction tied permanently to one project, the data center owner has fewer options when schedules change.
OFCI can also give data center owners greater visibility into equipment cost and reduce some of the markup layers that can occur when medium voltage equipment passes through multiple parties before reaching the owner.
Depending on the contracting model, MV equipment costs may include distributor, electrical contractor, general contractor, or other markups. Direct equipment procurement can make those costs more visible.
But I would not evaluate OFCI based on purchase price alone.
There are costs associated with managing equipment, storing it if schedules move, coordinating delivery, and handling the additional responsibilities that come with owner-furnished equipment. Those responsibilities need to be planned for rather than ignored.
There is also a financial value to schedule flexibility.
A medium voltage transformer that costs slightly less but delays energization is not necessarily the lower-cost option. The evaluation should consider equipment cost, procurement timing, management requirements, manufacturing risk, storage, logistics, and the impact of the equipment schedule on the overall project.
OFCI can also create opportunities to rethink how medium voltage infrastructure is assembled, tested, delivered, and installed. For the right project, a skidded medium voltage solution can move significant work away from the construction site and into a controlled factory environment.
Chateau Energy used this approach for a national colocation provider developing a remote campus with an aggressive go-live schedule. Medium voltage switchgear, transformers, and advanced controls were integrated into a pre-assembled, factory-tested solution. Standardized interfaces reduced field wiring and commissioning requirements, and components could be fabricated in parallel.
Installation was completed in weeks rather than months, with less onsite labor required.
A skid is not the right solution for every project. But it illustrates a larger point.
When the data center owner has more control of the equipment strategy and Chateau Energy is involved early enough, we can evaluate more than which manufacturer can ship a particular component fastest. We can look at how the overall MV package should be designed, manufactured, tested, delivered, and installed to support the energization schedule.
OFCI does not remove medium voltage equipment schedule risk. It gives the data center project team more control over that risk, particularly when MV equipment procurement and program management remain connected through energization.
This is the part I would not underestimate.
A data center owner can secure a transformer two years early and still have a problem if no one manages the submittals. A switchgear lineup can be completed on time and still miss the project if logistics are not coordinated. Equipment can reach the data center site and still delay commissioning because a technical issue was not identified earlier.
The value comes from managing the complete path.
Chateau Energy stays involved from equipment strategy and procurement through manufacturing, delivery, testing, and commissioning. When an issue occurs, we already know the manufacturers, equipment, project requirements, and schedule rather than entering the conversation after something has gone wrong.
We saw the importance of that ongoing visibility when protection relay issues appeared on a small number of data center sites. Our investigation identified a firmware pattern that potentially affected a much larger installed equipment base. Chateau Energy helped review approximately 200 pieces of switchgear and coordinate remediation across the program rather than allowing the problem to be rediscovered project by project.
That is the difference between buying equipment and managing an equipment program.
A well-managed OFCI program gives data center owners greater control over what they are buying, when they are buying it, what it costs, where it is allocated, and when it will arrive.
It should not require the owner to manage every manufacturer, submittal, production update, delivery, or commissioning issue to get that control.
That work can be managed as a coordinated program.
Early procurement can improve access to manufacturing capacity. Manufacturer relationships can create better visibility into available options. Standardization can make medium voltage equipment more flexible across projects. Program-level tracking can support reallocation. Skidded solutions can reduce onsite work. Continued management can keep equipment moving toward the actual objective: energization.
For data center developers with multiple projects and aggressive schedules, that is where I see the biggest advantage of OFCI. It gives the team more options early enough to use them.
If your data center program is facing long lead times for switchgear, transformers, medium voltage cable, or other critical electrical infrastructure, multiple upcoming projects, or aggressive energization dates, the equipment strategy should be evaluated well before the construction purchasing cycle begins.
Chateau Energy can manage that path from early equipment strategy and manufacturer engagement through procurement, production, logistics, testing, commissioning, and energization. The data center owner retains the visibility and control that makes OFCI valuable without having to take on the entire management workload internally.
The earlier that process begins, the more options there are to protect the equipment schedule and the energization date.

No. OFCI gives the data center owner greater control over the equipment purchase, but the day-to-day work can be managed by an experienced program management partner. Chateau Energy can manage manufacturer coordination, submittals, production tracking, logistics, delivery, testing, commissioning, and other medium-voltage equipment activities while keeping the owner informed through energization.
OFCI means Owner Furnished Contractor Installed. The owner furnishes specified equipment, such as switchgear, transformers, or medium voltage cable, and the contractor installs it. For long-lead MV infrastructure, this structure can allow equipment procurement to begin earlier than it would under a traditional contractor-led purchasing model. Chateau Energy helps data center owners manage the OFCI process by coordinating manufacturer relationships, equipment procurement, production tracking, logistics, delivery, testing, and commissioning.
Established manufacturer relationships can provide better visibility into production capacity, equipment configurations, manufacturing schedules, technical alternatives, and potential openings. Chateau Energy works directly with medium-voltage equipment manufacturers, which can help data center teams identify options earlier and develop procurement strategies around project and energization requirements.
Switchgear, transformers, medium voltage cable, and other critical electrical infrastructure can have procurement timelines that do not align well with traditional data center construction purchasing. OFCI allows owners to address those long-lead items earlier while creating more flexibility around equipment allocation, standardization, cost, and future project needs. Chateau Energy can support this process through its OFCI program management by helping data center owners coordinate manufacturer relationships, equipment specifications, procurement schedules, logistics, and delivery requirements.
No. OFCI gives data center teams more control over the equipment schedule, but submittals, manufacturing, delivery, installation, testing, and commissioning still have to be actively managed. Chateau Energy’s program management helps connect those steps so earlier procurement supports a more predictable path to energization.
Standardization is especially useful for data center owners developing multiple sites, campuses, or repeatable designs. Common equipment families, specifications, interfaces, and documentation can make forecasting, procurement, reallocation, stocking, maintenance, and replacement easier across the broader data center program. Chateau Energy can help data center teams develop and manage standardized medium voltage equipment strategies across projects, supporting more consistent procurement, documentation, and long-term program execution.
