Grid Interconnection Delays and What to Do About Them

If your facility has an expansion, a new production line, or a new building on the horizon, there's a good chance the electrical side of that project is about to take longer than it used to. Not because of anything wrong with the design or the equipment, but because the utility interconnection process itself has gotten backed up nationwide, and industrial facilities are increasingly getting caught in the same queue as an entirely different kind of customer.

Why Interconnection Queues Have Gotten So Long

The surge in AI and data center construction over the past two years has driven an unprecedented wave of requests for new grid capacity. Utilities and grid operators across the country are now managing interconnection queues that, according to industry tracking, add up to well over 2,000 gigawatts of pending generation, storage, and large-load requests nationally. Wait times in many regions now commonly stretch three to five years, and in some heavily congested markets, considerably longer.

Texas offers a clear, recent example. In August 2026, the state's grid operator paused review of new large-load interconnection requests after the queue swelled to roughly 470 gigawatts, with the vast majority of that demand coming from data center projects. That pause affects every type of large electrical load waiting in that same queue, not just data centers.

At the federal level, the Department of Energy directed FERC to act on new rules for large-load interconnection by mid-2026, specifically because the existing process wasn't built to handle this volume or pace of requests. That regulatory response is a signal of how structurally strained the system has become, not a sign that relief is imminent.

Why This Matters for Industrial Facilities, Not Just Data Centers

It's easy to read headlines about AI infrastructure and assume this is someone else's problem. It isn't. Utility interconnection queues and large-load review processes generally aren't segmented by industry. A new or expanded electrical service for a manufacturing facility, a new substation tap, or a significant increase in a site's connected load can land in the same review process as a data center campus, and get stuck behind it. Industrial facilities planning expansions are increasingly reporting multi-year timelines for utility interconnection approval, or being told a request can't be accommodated on the original schedule at all.

This is a planning problem as much as an electrical one. A project timeline that assumed a straightforward utility upgrade six months to a year out can suddenly be looking at a multi-year wait, with real consequences for production schedules, financing, and lease or construction commitments tied to that timeline.

What Facilities Are Doing About It

There isn't a single fix, but a few approaches are gaining real traction as facilities adapt to a slower grid.

Behind-the-meter generation. Installing on-site generation, whether that's natural gas generators, on-site solar paired with storage, or a combination, gives a facility power that doesn't depend on the utility's interconnection timeline at all. This is increasingly common for facilities that can't wait years for a grid connection to catch up with their project schedule.

Flexible interconnection agreements. Some utilities are now offering interconnection paths that trade full, unconstrained capacity for a faster connection, in exchange for the facility accepting some operational limits, such as curtailing load during specific grid conditions. It's not the right fit for every operation, but for facilities with some flexibility in when they run their heaviest loads, it can mean getting connected years sooner.

Reducing the size of the ask. A facility that can lower its peak demand through power quality improvements, load management, or on-site energy storage may be able to request a smaller service upgrade than originally planned, which can move through review faster and cost less in system upgrade charges than a larger request would.

Starting the utility conversation earlier. Given how long studies and queue positions are taking, the facilities managing this best are the ones bringing utilities into expansion planning far earlier than they used to, before equipment is ordered or a production timeline is finalized around an assumption that may no longer hold.

How HRE Can Help

Electrical capacity planning has always mattered for industrial expansions, but it now has to account for a utility interconnection timeline that can no longer be assumed to be quick. HRE Construction works with facilities early in the planning process to right-size electrical service requests, evaluate where on-site generation or standby power can offset interconnection delays, and design the switchgear, distribution, and controls that make those options workable rather than just theoretical. Getting these decisions right at the design stage is far cheaper than retrofitting around a delay you didn't see coming.

If an upcoming project depends on new or expanded utility service, contact HRE Construction early to talk through what your timeline actually looks like.

Frequently Asked Questions

Are grid interconnection delays only affecting data centers?

No. While data center and AI infrastructure demand is driving most of the growth in interconnection queues, industrial facilities requesting new or expanded utility service often go through the same review process and can face similar multi-year delays, particularly in regions where queues are already congested.

How can a facility avoid getting stuck in an interconnection delay?

Starting the utility conversation as early as possible in the planning process is the single biggest factor. Beyond that, options like reducing peak demand through power quality improvements, considering behind-the-meter generation, or exploring flexible interconnection agreements can all shorten the effective timeline or reduce dependence on the utility's queue position.

Does on-site generation replace the need for a utility connection?

Not usually. Most facilities that install behind-the-meter generation still maintain a utility connection for baseline power and reliability, but the on-site generation reduces how much new capacity they need from the grid, or lets them operate on a project timeline that isn't dependent on interconnection approval.
