Data Centers Are Waiting Years for Power. Substation Builders Are the Answer

The scale of the wait

According to a 2026 market-by-market review from Construction Owners, JLL's 2026 outlook puts a 100 MW grid connection in Northern Virginia at about seven years, against a national average of around four. The same piece notes that Dominion Energy's queue for new substation service stretches beyond 36 months, and that utilities could typically accommodate large commercial loads in 12 to 18 months before 2022.

Texas shows the same pressure. The article reports ERCOT's large-load queue at about 410 GW as of April 2026, roughly five times current generating capacity, with data centers making up around 73% of it. Not all of that will be built, but it shows how much demand is competing for the same grid upgrades.

Equipment is part of the story. The article notes that a substation approved today may not be built until 2027 or 2028 because of equipment constraints, and cites iMasons for large power transformer lead times of two to four years.

Why this lands on substation and civil teams

Every large load needs a connection point. In practice that means new or expanded substations, new transmission or distribution feeders, and a lot of site preparation. The work is not glamorous, but it is the critical path.

Siteworks and earthworks. Substation yards need grading, drainage, grounding grids, conduit banks and foundations for equipment and control buildings. This work often starts years before the equipment arrives, and it needs experienced civil superintendents who can deliver it to tolerance.

Substation project management. Coordinating an OEM supply chain with a utility outage schedule and an owner's energisation date is a specialist skill. A project manager who has run substation builds can protect weeks of float that a generalist might lose.

Design and protection engineering. Utilities and developers need engineers who understand protection, control and interconnection requirements, and who can work with utility standards rather than against them.

Commissioning and testing. When the equipment finally arrives, testing and commissioning is what stands between delivery and energisation. Our field services and testing work shows how often this is the tightest part of a schedule.

Why speed to hire matters more than usual

Developers are now chasing sites where power can be delivered in 12 to 24 months, as the Construction Owners piece describes. That target puts pressure on every step before energisation. If a site is ready and the substation team is not, the lead time on equipment is no longer the only delay.

Three things we hear from clients are worth passing on.

First, the best substation and civil candidates are rarely unemployed. Plan for a search measured in weeks, not days, and give candidates clear information about scope and voltage class.

Second, location is a real barrier. Many of the fastest-growing data center markets are not where experienced substation crews live. Relocation support, rotational patterns or contract roles can make a hard-to-fill site workable.

Third, hiring models can be mixed. A permanent project lead, supported by temporary civil and commissioning cover for peaks, often fits a connection programme better than a single approach.

What to do now

If you are developing, building or supplying a data center connection, start with the long-lead items and treat the people as part of the same plan. Map the roles you need against the equipment delivery dates, work backwards, and open the searches earlier than feels necessary.

Our transmission and distribution team works with contractors, utilities and developers on exactly this kind of build. If you have a connection programme to staff, talk to us about a multi-hire approach, or browse our open roles if you are looking for your next substation or civil move.
