What is behind-the-meter generation for a data center?
It is generation electrically connected on the customer side of the utility revenue meter. The plant may support the campus alone, parallel with the grid, export under an approved arrangement, or transition between modes. “Behind the meter” does not automatically mean off-grid or exempt from utility, air, fuel, AHJ, or market requirements.
Which generation technologies can serve an AI campus?
Candidates include natural-gas or diesel reciprocating generators, aeroderivative or industrial-frame gas turbines, steam turbines when a suitable steam cycle exists, and hybrid systems. Compare net site output, unit size, redundancy, load following, efficiency, starts, fuel, emissions, maintenance, footprint, black start, schedule and lifecycle cost.
| Technology | Potential fit | Verify |
|---|---|---|
| Modular reciprocating engines | Phased capacity and multiple-unit redundancy | Duty, fuel, emissions, transient performance, maintenance and controls |
| Aeroderivative gas turbines | Packaged turbine blocks and cycling capability by model | Net site output, fuel, emissions, auxiliaries, maintenance and generator scope |
| Industrial-frame turbines | Consolidated larger generation blocks by model | Construction/BOP, duty, maintenance, emissions, black start and outage strategy |
| Steam turbines | Power from an available steam process or combined cycle | Steam conditions, condenser/cooling, generator, auxiliaries and source reliability |
What electrical equipment belongs in a behind-the-meter plant?
The package may include prime movers, electrical generators, generator breakers, GSUs, unit auxiliary and startup transformers, MV/LV switchgear, protection, grounding, paralleling and microgrid controls, black-start sources, SCADA, metering, plant distribution, and campus interconnection. Every battery limit should be explicit.
What fuel and emissions data is needed before equipment selection?
Provide fuel type, composition, pressure, temperature, volume, curtailment/backup plan, pipeline or storage status, site jurisdiction, intended emergency or non-emergency duty, annual hours, load profile, permit limits, and required emissions controls. Equipment availability is irrelevant if the package cannot support the permit or fuel basis.
What should a Texas or ERCOT data-center project submit?
Submit site/county, utility or ERCOT context, desired operating mode, campus MW and ramp, fuel/gas data, generator and campus voltages, emissions assumptions, redundancy, black-start target, export intent, first-power date, permanent-power plan, one-line, and responsible engineering/interconnection contacts. J&J does not represent that behind-the-meter status removes regulatory review.
Can used or surplus generation equipment shorten the schedule?
It may shorten the factory-supply portion only when identity, title, condition, preservation, documents, completeness, inspection, refurbishment, testing, controls, emissions, dismantlement, transport, foundations, reassembly, auxiliaries, and commissioning fit the critical path. A ready-to-ship label is not a ready-to-operate plant.
Availability is subject to prior sale, technical review, and written confirmation by J&J Transformers LLC.
What belongs in a behind-the-meter package RFQ?
Provide total campus MW, initial/future phases, load profile, redundancy, preferred or open technology, fuel, generator voltage, interconnection voltage, campus MV, island/grid-parallel modes, black start, emissions jurisdiction, location, first-power date, package scope, condition acceptance, one-line, and known studies. Unknown fields can be marked for development.
Frequently asked questions
These answers explain the procurement and application questions buyers ask most often. Unit-specific ratings, availability, conformity, condition, price, and delivery are controlled by the written quotation and supporting documents.
What is behind-the-meter generation?
Generation connected on the customer side of the utility revenue meter, under an approved islanded, parallel or other operating arrangement.
Can behind-the-meter power serve an AI data center?
Yes when reliability, fuel, emissions, permitting, electrical, operating, maintenance and owner requirements are satisfied.
Does behind the meter mean off-grid?
No. It can be islanded, grid-parallel or transitional depending on the approved design.
What generation technologies can be used?
Gas or diesel engines, gas turbines, steam turbines in suitable cycles, and hybrids are possible project-specific candidates.
When is a GSU needed?
When generator terminal voltage must be raised to the plant or interconnection bus voltage.
What must be studied before procurement?
Load flow, short circuit, protection, grounding, harmonics, transients, reliability, fuel, emissions, site and operating modes.
Can a project export power to the grid?
Only under applicable utility, market, interconnection and regulatory arrangements.
What information is needed for a Texas project?
Site, utility/ERCOT context, MW/ramp, fuel, voltage, emissions assumptions, mode, redundancy, one-line and required date.
Can used equipment shorten the schedule?
Potentially, but inspection, missing scope, refurbishment, emissions, controls, transport and integration can offset factory-time savings.
Can J&J guarantee an energization date?
Only obligations expressly stated in an accepted written agreement control; general web copy is not a schedule guarantee.
