Somewhere on your facility sits a utility meter. Easy to walk past, but that unassuming box marks the front line of the biggest shift underway in energy: who makes your power, and where. Everything on the utility’s side is “in front of the meter.” Everything on yours is behind it, and behind the meter is suddenly where the action is.
For decades, behind-the-meter power meant a backup generator that coughed to life a few hours a year. No longer. Manufacturers, hospitals, campuses, mining and midstream operations, and, most visibly, data centers are designing on-site generation as primary or supplemental power. Why? Interconnection queues that stretch years. Demand charges that keep climbing. Grid congestion at the worst moments. Uptime the grid can’t promise. On-site generation puts the schedule, reliability, and cost structure back in the owner’s hands, and keeps the facility’s demand off the shared grid, where it would compete with the surrounding community. It’s no longer a workaround. It’s an energy strategy.
Ask anyone building an AI data center what keeps them up at night. It isn’t land. It isn’t chips. It’s electrons. The race to build AI infrastructure has become a race to secure electricity: one campus can demand as much power as a small city, on a timeline of months, while a grid connection takes years, and in more and more markets, regulators are re-examining how much large-load growth the grid can absorb at all. So, the industry scores projects on “time to power” and simply brings its own: gas-fired plants built at the site, with the grid demoted to supplemental or backup duty.
Generating the electricity, though, is only part of the equation.
An on-site power plant, whether 100 MW or far larger, consumes an enormous amount of fuel, and needs it with the same reliability the facility expects from its power. Natural gas will likely remain the primary fuel for most projects. But before the first generator fires, every developer has to answer a harder set of questions:
Those questions move the conversation beyond power generation and into energy resiliency, and that’s where LPG, LNG, CNG, and synthetic natural gas (SNG) come in. Depending on the plant’s size, location, and operating profile, LPG, LNG, and CNG can serve as the bridge fuel that lets a facility start up before the pipeline arrives, the backup that keeps generators running through a curtailment, or the peak-shaving supply that covers demand the pipeline can’t. SNG, a proven technology that utilities and industrial facilities have used for decades to supplement pipeline gas, is now being explored as a potential bridge and standby fuel for power generation applications as well. For mission-critical facilities, the answer is often a multi-fuel strategy: a plant designed to keep operating even if its primary fuel is interrupted.
The resiliency of behind-the-meter power, in other words, ultimately depends on the resiliency of its fuel supply.
This is where TransTech brings a different capability to the conversation. For more than 60 years, our teams have engineered, fabricated, installed, and supported fuel storage and delivery infrastructure for LPG, LNG, CNG, and NGL applications, the same systems behind-the-meter generation depends on: bulk storage, truck unloading and transfer, pumping and compression, vaporization, pressure regulation and control, SNG systems, fuel-switching and backup-fuel infrastructure, and modular, prefabricated fuel systems, with in-house engineering, ASME fabrication, installation, commissioning, and field services under one roof.
Our SNG and propane-air peak-shaving experience is especially relevant. Utilities and industrial facilities have relied on these systems for decades to maintain gas service when pipeline supply can’t meet demand, and that proven track record is why SNG is now being explored as a potential bridge and standby fuel for on-site power generation. Data center development faces the same fundamental challenge these systems were built to solve: how do you make sure a facility has reliable fuel, when and where it’s needed? We’ve been answering that question since long before anyone measured projects in “time to power.”
Behind-the-meter power provides the path. A resilient fuel strategy makes the path reliable.
If your organization is evaluating on-site generation, bridge fuel, or backup fuel, for a data center or any power-hungry facility, TransTech Energy can develop the storage, transfer, vaporization, and fuel-delivery infrastructure the generation plant requires.

What does “behind the meter” mean?
Behind-the-meter (BTM) power is electricity generated on the customer’s side of the utility meter, produced and consumed on-site rather than drawn from the grid. Everything on the utility’s side (power plants, transmission lines, substations) is “in front of the meter.”
Why are data centers turning to behind-the-meter power?
Grid interconnection can take years, while data centers need hundreds of megawatts on construction timelines measured in months. On-site generation puts the schedule, reliability, and cost structure in the facility owner’s hands, which is why the industry now measures projects in “time to power.”
What is a bridge fuel?
A bridge fuel is a temporary fuel supply, typically LPG, LNG, or CNG delivered and stored on-site, that allows a facility to begin operating before permanent pipeline infrastructure is in place. Once pipeline gas arrives, the same systems can often transition to a backup or peak-shaving role.
What fuels power behind-the-meter generation?
Natural gas is expected to remain the primary fuel for most projects. LPG, LNG, and CNG serve as bridge, backup, and peak-shaving fuels. Mission-critical facilities often adopt a multi-fuel strategy so the plant keeps operating even if its primary supply is interrupted.
What is SNG, and can it fuel power generation?
Synthetic natural gas (SNG), produced by blending vaporized propane with air, is a proven technology that utilities and industrial facilities have used for decades to supplement pipeline gas during peak demand. It is now being explored as a potential bridge and standby fuel for power generation applications.
Does TransTech build power plants?
No. TransTech designs, fabricates, and installs the fuel infrastructure that on-site generation depends on: bulk storage, transfer, vaporization, pressure regulation, SNG systems, and backup-fuel infrastructure. We supply the fuel layer, whoever builds and owns the generation.
