The utility can't get you power fast enough. Here's what can.
Plain-English explanations of behind-the-meter power for data centers — gas turbines, BESS, interconnection queues, and the switchgear in between. Written by someone who's spent a career on the equipment, not the sales deck.
What “behind-the-meter” actually means
// 01 — FUNDAMENTALSUTILITY INTERCONNECTION
IN CONSTRAINED MARKETS
Behind-the-meter (BTM) power is generation that sits on the customer's side of the utility meter — a gas turbine, a fleet of reciprocating engines, or a battery system installed on-site, feeding the load directly instead of routing power through the utility's wires.
For data centers, the driver isn't cost. It's time. Interconnection queues in the hottest markets now run years long, and hyperscale campuses can't wait that long to turn on. BTM generation gets a facility to first power on a schedule the grid can't match, and can run in parallel with the utility, in island mode, or as a bridge until permanent interconnection arrives.
The tradeoff is real: BTM assets have to be sized, permitted, fueled, and maintained by someone. That's where the engineering gets specific — and where most of the confusion in this market comes from.

// 02 — TOPICS COVERED HEREGas Turbines & Reciprocating Engines
How aeroderivative turbines, heavy-duty frames, and recip engine fleets actually compare on ramp rate, footprint, fuel flexibility, and lead time — not just nameplate MW.
Battery Energy Storage (BESS)
Where storage earns its place in a BTM stack — ride-through, peak shaving, black start support — and where it's oversold.
Interconnection Queues
Why queue times vary so widely by ISO and utility territory, and how that timeline should actually shape a site selection decision.
Switchgear & Distribution
The unglamorous equipment that makes or breaks a BTM install — switchboards, zone-selective interlocking, and the standards that govern them.
Permitting & Siting
Air permits, county moratoria, and the regulatory terrain that decides whether a BTM project ships on time or stalls for a year.
Utility Power vs. BTM Generation
A level-headed look at when grid power still wins, when BTM is the only realistic path, and when the right answer is both.
About
// 03 — WHO'S WRITING THISI've spent nearly four decades selling and specifying industrial electrical equipment — switchgear, motor control, VFDs, transformers — across the western U.S. For the last stretch of that career, the center of gravity has shifted hard toward one problem: getting AI data centers enough power, fast enough.
This site is a place to write down what that actually involves, in plain language, without a sales pitch attached. No lead forms, no gated content. Just the same explanations I'd give a colleague over coffee.
A brokerage offering built on this same focus is in the works — a link will land here when it's ready.
