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
440 GW — 1,797 active requests
In the PJM queue
171.5 GW — 968 active requests
Power transformer wait
128 wks — large units, 80 to 156 range
Queue to energization
5.1 yrs — up from 3.2 in 2022

Power Is the Constraint

Every data center needs power. A lot of it. And the grid was not built for this.

The tracker follows 366 data centers totaling 183.7 GW of capacity. The interconnection queues we mirror are bigger still: 440 GW across 1,797 active ERCOT requests and 171.5 GW across 968 in PJM. Most of that is generation waiting to serve load that does not exist yet, and a growing share of the load is data centers.

The Queue Is Growing Faster Than Approvals

The average time from interconnection request to energization has increased from 3.2 years in 2022 to 5.1 years in 2025. This is the single biggest constraint on the data center buildout.

The queues are being reformed while they grow. PJM is clearing the last ~46 GW of its old backlog in Transition Cycle 2, due to finish by the end of 2026, with the first cycle of its reformed process queued behind it. 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 1,400 MW 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.

This is why the DC Index weights power infrastructure companies alongside traditional data center REITs — the bottleneck is where the pricing power lives.

What we're watching

Q4 2026
Whether PJM clears the last ~46 GW of its old backlog in Transition Cycle 2 by year end, or the reformed process inherits the same pile.
Ongoing
Power transformer lead times, 80 to 156 weeks for large units. 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.
