The Power Problem: Why Utilities Are the Real Data Center Bottleneck

Published: · Updated:

Interconnection queues are growing faster than capacity. The data shows a critical gap between planned data center capacity and available power infrastructure.

In the ERCOT queue
453.3 GW, 1,833 active requests
In the PJM queue
171.9 GW, 968 active requests
Power transformer wait
130 wks, 30-month average, H1 2025
Request to operation
5.1 yrs, up from 3.0 in 2015

Power Is the Constraint

Every data center needs power. A lot of it. And the grid wasn't built for this.

The tracker follows 708 data centers totaling 264.0 GW of capacity. The interconnection queues we mirror are bigger still: 453.3 GW across 1,833 active ERCOT requests and 171.9 GW across 968 in PJM. Most of that is generation waiting to serve load that doesn't exist yet, and a growing share of the load is data centers.

The Queue Is Growing Faster Than Approvals

The median project built in 2025 took 61 months, about 5.1 years, from interconnection request to commercial operation, up from 36 months in 2015, per Berkeley Lab. This is the single biggest constraint on the data center buildout.

The queues are being reformed while they grow. PJM's Transition Cycle 2, the last batch of its old backlog, started with 55 GW and had lost 25 GW to withdrawals by June. What's left entered its third study phase on July 8, and the first cycle of the reformed process began its Phase I studies on September 28. In ERCOT, the tell is where the speculative capacity lands: two thermal generation requests in Hill County, Texas, Bullock Gas and Liberty Thermal Energy Center, have 1.4 GW each filed with system studies complete, no interconnection agreement, and an expected in-service date of July 2032. Two adjacent 1.4 GW requests in one rural county, six years out, is a specific bet on where Texas capacity gets built.

Who Benefits?

Companies positioned in the power infrastructure supply chain:

The Investment Implication

The power constraint creates a natural moat for existing data center operators with secured power agreements. New entrants face 3-5 year delays just to get grid access.

That's why the power suppliers matter as much as the data center REITs: the bottleneck is where the pricing power lives.

What we're watching

Phase III, 2026 to 2027
Whether what's left of PJM's Transition Cycle 2 reaches signed agreements, or the reformed process inherits the same pile.
Ongoing
Power transformer lead times, a [30-month average for large units](https://docs.nlr.gov/docs/fy26osti/96742.pdf) in the first half of 2025. A sustained move below 100 weeks re-times every project in the tracker.
2032
The two 1.4 GW Hill County, Texas requests. Filed six years out, they mark where ERCOT capacity is actually headed.
