Ever wondered what actually stops a growing tech company in its tracks?
It isn’t chips. It isn’t funding. It isn’t even hiring.
It’s electricity.
For years startup growth plans have followed the same recipe: raise capital, buy servers, rent a building and scale. But today there’s a new addition to that plan. It’s also the slowest part of the process – securing enough juice to power the place.
The numbers are staggering. Data centres’ demand for electricity jumped 17% in 2025. Meanwhile, the grid they rely on only grew a fraction of that rate.
Here’s the good news:
Delays are well understood. Once you pinpoint precisely why they occur, you can schedule around them instead of waiting behind them for three years.
What you’ll uncover:
Why Power Became The Growth Ceiling
Electricity was the dull part of every build. Someone signed a utility contract, an electrician came out and wired everything up, then everyone moved on.
Not anymore.
Compute has never been so dense. What used to be a 5 kW rack pulls 50 kW or more these days. All that power has to flow through switchboards, breakers and busbars before it ever reaches a server. When that equipment is bulky or subjected to dust and humidity, you lose valuable floor space and invite downtime.
Which is why so many operators specify gas-insulated switchgear, which contains busbars, breakers and live connections within encapsulated primary compartments filled with insulation gas. Enclosed primary spaces prevent moisture, dust and salt air from contaminating energized parts, reduce the electrical room footprint and reduce the maintenance your facilities team needs to manage.
More power, in less space, with fewer things that can fail.
Think about it:
If your building can only accommodate one electrical enclosure, then whatever technology is in that enclosure determines how much load your business can handle. That’s not an engineering fact. That’s your growth limit.
Where The Real Delays Come From
Most assume power delay means “power company dragging their feet.” Nothing could be farther from the truth. Two completely separate queues exist to delay everyone. They operate simultaneously.
The Grid Queue
Want to connect a large new load to the grid? Get in line.
Approximately 2,061 GW of capacity is awaiting approval in U.S. interconnection queues today. That’s greater than current installed capacity. In some of the most congested markets, it takes between four and seven years to get from application to switch-on.
Read that again. Four to seven years.
That exceeds the time it takes to design, construct and furnish the building. Therefore the power application, not the construction timetable, now dictates your opening date.
Plus the line just keeps growing longer as everyone rushes to apply. Hyperscalers, manufacturers, battery projects – everyone’s after the same connection points, so every new application just moves the finish line further back.
The Equipment Queue
Here’s the part almost nobody plans for…
Of course, just because the utility approves doesn’t mean you actually have the hardware to accept that power. The plants making that equipment are massively backed up. Lead times for power transformers are hovering around 128 weeks from order to delivery. High voltage circuit breakers have seen lead times grow to about 125 weeks.
Medium-voltage switchgear isn’t too far behind either. Lead times of a year or more are not unusual for stock equipment specifications.
Meaning a PO that was once standard now has a two year commitment behind it. And that’s just the beginning, global data centre demand is expected to consume 950 TWh by 2030. Demand for equipment will continue to increase only.
What Sealed Primary Compartments Change
Now for the practical bit.
You cannot schedule around the grid queue. However, you can DEFINITELY increase how much usable energy fits into your allocated space. That’s what sealed primaries are for.
Old style air-insulated equipment relies on air to do the insulating. Air requires spacing. Lots of spacing. By sealing primary compartments and replacing that air space with insulating gas in a welded metal container, the same voltage can be accommodated in a much smaller box.
What that gives a growing business:
Speaking of saving space, there’s a positive side effect to this. Less room dedicated to your electrical room means that square metre goes back to equipment that generates revenue. If you’re paying top dollar for urban square metres, that math will work out quickly.
How Smart Teams Beat The Power Crunch
Waiting isn’t a strategy. These three moves are.
Treat Power As A Day-One Decision
Traditionally, teams have sized their power needs after identifying their site. Those days are over.
Begin with the five year not current load. Second look at the interconnect queue. Substation headroom and equipment lead times BEFORE you sign a lease. A marginal site with capacity today is better than an ideal site with a six year wait every time.
Order The Long-Lead Gear Early
Switchgear and transformers that take 24 months to deliver should not be an afterthought. Book your production window early on in the design process, even if some details are still floating.
Teams that place orders late aren’t saving money. They’re just moving their launch date.
Build In Headroom You Don’t Need Yet
Adding capacity later means a new application, a new queue and a new order.
Choose switchgear capable of accepting additional feeders. Oversize conduit and pads, and allow space for future equipment when planning phase one. Smaller footprints allow for this much easier, as primary seal off’s allows space you would normally need for expansion.
The Bottom Line On Power And Growth
Power capacity is sneaking up as the new hard limit on technology development. Not disk space. Not funds. Watts.
The companies that scale comfortably these days aren’t those with the biggest budgets. Those that realized early on that a four year grid queue and two year equipment queue needed to be put into place TODAY, and run concurrently.
Plan ahead. Place your order as soon as possible. Use small, closed-top containers to maximize storage space.
Go do that and suddenly power stops being the limiting factor in your growth. It becomes the enabling factor.
