Time to Power in ERCOT: What Drives It

By Batu Yetki, founder of Voltane.

What time to power measures

Time to power can be measured to two milestones:

From the interconnection request to a signed interconnection agreement.
From the interconnection request to energization, the day the connection is switched on.

Be clear which one a number refers to. Also note that many requests never finish. The share of past projects that reached operation is part of the picture.

Driver 1: Where the site is

Different parts of the ERCOT grid have different amounts of existing infrastructure and different levels of demand for new connections. The same project can face a short wait in one zone and a long one in another.

Driver 2: Voltage class

The voltage of the line or substation a project connects to shapes the equipment needed and the scale of the work. Voltane groups its estimates by voltage class for this reason.

Driver 3: How crowded the queue is

When many projects ask to connect in the same area, studies get more complex and upgrades are shared across more parties. Queue crowding is a competition signal. It does not measure how much room the grid has.

See the glossary entry on the interconnection queue.

Driver 4: Upgrades, equipment and readiness

Grid upgrades. If the study finds that new lines or substation work are needed, the project waits for them.
Equipment. Large electrical equipment can take a long time to arrive. Ask suppliers and your utility for current lead times.
Your own readiness. Site control, funding and permits affect how fast you can move through each step. For large loads in Texas, SB 6 requires site control and security before the study starts.
Planned transmission. A planned project nearby can help later. It is a dated fact, not capacity.

How Voltane estimates it

Voltane does not model a single site's connection. It places a site in a group by its ERCOT zone, its voltage class and how crowded the queue is nearby. It then reports what happened to past projects in that group, as a range: a low, a middle and a high value taken from the lower quartile, the median and the upper quartile.

Every estimate names its group and the number of past projects behind it. A group with few projects gives a weak estimate, and the count is shown. Estimates are kept apart from sourced facts. The full method and its backtest are in How Voltane estimates time to power.

What the estimate does not tell you

It is generation queue history, not large-load history. The public record covers power plants and storage. A data center goes through a different process, and its timeline can differ.
A group is not a site. The estimate does not study your substation, your line or your request.
An estimate is not a promise. It is not available capacity, a queue position or a date a utility has agreed to.

Questions people ask

How long does it take to get power in ERCOT?

It depends on the zone, the voltage, queue crowding and the upgrades needed. Voltane publishes ranges by group in its research, based on generation queue history. Ask your utility for a site-specific answer.

Is time to power the same for a data center and a power plant?

No. Large loads and generators follow different processes. Voltane's estimates come from generation queue history and are labelled that way.

Is a time to power estimate a guarantee?

No. It is a range drawn from past projects in a similar group. It is not a date a utility has agreed to.
