Gas-to-Power and BTM Generation Siting

By Batu Yetki, founder of Voltane.

What the terms mean

Behind-the-meter generation is a power plant on the customer's side of the utility meter. It serves the site directly. Gas-to-power, as used here, means building gas-fired generation to supply a large load such as a data center, either as the main supply, as a bridge until grid power arrives, or alongside a grid connection.

Why projects consider it

Timing. On-site generation may be available before a full grid connection.
Control. The project relies less on grid upgrades it does not manage.
Phasing. A site can start on its own power and add grid service later.

It also adds cost, permits and operating work. Whether it is faster or cheaper depends on the site.

Fuel: the first siting question

A gas plant needs gas. Start with where pipelines run, then ask the questions a map cannot answer:

Does the pipeline have capacity for your volume?
Can you get firm transport, or only interruptible service?
Will the operator allow a tap, and what will the lateral cost?
What pressure is available at the site?

A mapped pipeline near a site is proximity only. It is not deliverable fuel, firm transport or a tap right. Voltane's pipeline layer comes from a public federal data set that covers major lines only and is several years old, so treat it as a starting point.

Land, air, water and neighbors

Land. On-site generation needs room for the plant, fuel handling, a switchyard and setbacks, on top of the data center itself.
Air permits. Gas-fired generation needs air permits. Local air quality status can make permits harder in some areas. Check with the state environmental agency early.
Water. Some generation and cooling designs use a lot of water. Others use little. Match the design to what the site can supply.
Noise and neighbors. A power plant changes how a project is seen locally. Distance from homes helps.

The grid still matters

Most projects with on-site generation still want a grid connection, for backup, for growth or to sell surplus power. So the usual power checks still apply: the serving utility, distance to transmission and substations, queue activity and the point of interconnection.

Rules for how on-site generation and grid service work together are set by the regulator and the grid operator. In Texas, check the current PUCT rules and ERCOT requirements, including how Texas SB 6 applies to your setup. This guide does not cover those details.

A first-pass screen

Set the load, the energization year and how much on-site generation you plan.
Find land of the right size near both a mapped gas pipeline and transmission.
Remove flood zones, wetlands and protected land.
Check the serving utility and grid.
Take the shortlist to pipeline operators, the utility and the air permitting agency.

Voltane runs steps 2 to 4 for Texas as part of Find me a site. Gas-to-power is one of its lead use cases. The output is a screening, not a site suitability determination.

Questions people ask

What is behind-the-meter generation?

It is generation on the customer's side of the utility meter that serves the site directly, such as a gas plant built next to a data center.

Does a nearby gas pipeline mean I can get gas?

No. A mapped pipeline is proximity only. Capacity, pressure, firm transport and the right to tap are questions for the pipeline operator.

Do I still need a grid connection with on-site generation?

Most projects still want one for backup or growth. The rules for combining the two are set by the regulator and grid operator, so check the current requirements.

Need a site, or have one?

Tell us what you need and Voltane finds, reports on and prices candidate sites in ERCOT. Or bring a site you already have for a path-to-power report (by request for now).
