Part 1 Technical Blog: When the Load Becomes the Largest Machine on the Grid

1. A New Class of Grid Citizen

For a century, power system planning treated load as the predictable side of the ledger. Generators were the complex machines that needed models, studies, and performance requirements; load was an aggregate — millions of motors, lights, and appliances whose statistical behavior smoothed itself out. That assumption has now been broken, decisively, by a new class of facility: single-site loads of 500 MW to 1.5 GW built around power electronics rather than iron and copper.

The July 2026 ESIG Large Loads Task Force report on large-load behaviors, capabilities, and limitations — one of eleven reports produced by that task force — confirms what interconnection engineers have been seeing in study queues for the past two years: the majority of forecast load growth over the next five years comes from hyperscale data centers, AI training campuses, cryptocurrency mining facilities, hydrogen electrolysis plants, and large manufacturing. These facilities do not behave like the loads embedded in legacy planning models. They ramp in seconds. They trip in milliseconds. They respond to token prices, electricity prices, and training-job schedulers rather than to weather and time of day. And because they interface with the grid through rectifiers, uninterruptible power supplies, and DC/DC converters, they bring converter dynamics — the same class of dynamics that reshaped generation interconnection over the past decade — to the demand side of the meter.

At Keentel Engineering, we have long argued that grid interconnection is a first-order engineering input, not a downstream administrative step. Nowhere is that more true than for gigawatt-class loads. A facility's internal power distribution architecture, UPS topology, cooling drive selection, and protection philosophy are made years before energization — and every one of those decisions determines how the facility will behave during the grid fault it will inevitably experience. This article walks through the behaviors, capabilities, and limitations of the three load classes reshaping interconnection queues — data centers (including AI campuses), cryptocurrency mining, and hydrogen electrolysis — and translates them into the study, modeling, and compliance work that developers and utilities must now perform.

2. Four Ways Large Electronic Loads Threaten Operational Security

Industry analysis converges on four distinct problem classes that large power-electronic loads introduce to bulk power system operation. Understanding which of the four applies to a given facility is the first step in scoping an interconnection study correctly.

The first is speed. Modern electronic loads can move hundreds of megawatts in seconds, and the power-electronics interface between the load and the grid introduces control-loop dynamics that legacy load models never contemplated. Highly variable AI training workloads, aggregated across a fleet of campuses, can consume balancing reserves that were procured against far slower load behavior.

The second is trip sensitivity. Electronic loads are protective by design — their protection settings exist to save servers, not to support the grid. When a transmission fault depresses voltage across a wide area, many large loads can reduce demand or disconnect simultaneously. Losing gigawatts of load in an instant produces the mirror image of a generation trip: over-frequency and over-voltage conditions with genuine cascading potential.

The third is forecastability. Cryptocurrency miners chase real-time energy prices. AI training facilities start and stop billion-parameter jobs at a scheduler's discretion. Neither behavior maps onto the weather-and-calendar regressions that underpin conventional short-term load forecasting, which complicates everything from reserve procurement to day-ahead unit commitment.

The fourth is power quality — harmonics and oscillations. Rectifier front ends, power factor correction stages, and variable frequency drives all emit harmonics and, under the wrong impedance conditions, can become the source of forced or converter-driven oscillations that interact with nearby synchronous generators. As we discuss below, these are no longer theoretical: they have been measured, replicated, and corrected at operating facilities.

Keentel Insight

These four problem classes map directly onto four study products: dynamic and EMT modeling for speed, ride-through and protection coordination review for trip sensitivity, operational load characterization for forecastability, and harmonic/oscillation screening for power quality. An interconnection scope that omits any of the four is incomplete for a facility above roughly 100 MW.

3. Inside the Modern Data Center Power Chain

A large data center connects to the transmission system and steps utility voltage down through a familiar chain: a main power transformer to a medium-voltage network around 11 kV to 15 kV, medium-voltage distribution throughout the building with backup generators paralleled to those buses, and a final transformation to roughly 400 V AC at the server rack level. What makes the facility electrically interesting is not the transformers — it is everything between the medium-voltage bus and the silicon.

Nearly all compute and power equipment inside the facility is designed to the ITIC (formerly CBEMA) voltage tolerance curve, which defines the envelope of voltage magnitude and duration that IT equipment must withstand without damage or shutdown. When grid voltage exits that envelope, the facility transfers to its UPS or battery backup, and if the disturbance persists, to on-site generation. A facility with no backup will simply disconnect along the ITIC boundary.

Here is the problem, and it is the single most important concept in large-load interconnection today: the ITIC curve was written to protect computers, not the grid. Its voltage tolerances are misaligned with the disturbance profiles the bulk power system actually produces. A normally cleared transmission fault — well within the planning criteria every utility studies — can push voltage outside the ITIC envelope long enough to shed an entire campus. The load "worked as designed," and the grid inherited a gigawatt-scale contingency it never studied. This is precisely why dedicated large-load voltage ride-through requirements, written from the grid's reliability perspective rather than the server's, are emerging across the industry — and why ERCOT's NOGRR282 and NERC's developing large-load work matter so much to project schedules.

Compounding the misalignment is opacity. Data center operators and their vendors treat IT equipment specifications as confidential, so the interconnecting utility frequently cannot determine the voltage level at which the facility will actually disconnect. In our study practice, the ITIC curve serves as a reasonable default proxy for fault response modeling — but the modeler should always request the facility's actual ride-through characterization, and interconnection agreements should compel its disclosure.

3.1 The UPS: A Small Converter Plant Hiding Inside the Load

The double-conversion UPS is the workhorse of enterprise, colocation, and hyperscale facilities. Its front-end rectifier regulates a DC bus and manages grid-side power factor; its back-end inverter feeds the data center bus, buffering the load from grid-side distortion; a battery hangs on the DC bus, always ready. Three operating modes — normal, eco/bypass, and battery — are transferred between seamlessly. UPS runtimes vary with the business served: on the order of one to two minutes at hyperscale facilities, around five minutes for cloud and colocation, and ten to fifteen minutes where financial customers demand it.

Under a grid voltage sag, the DC bus sags with it. Because the IT load is constant-power, current rises as voltage falls — and if the rectifier hits its current limit, it blocks and shuts down, transferring the facility to UPS power. Recovery is asymmetric: a facility riding on its UPS can return to the grid within seconds, but a facility that has transferred to backup generation cannot. Backup generators carry minimum run times, typically twenty to thirty minutes, which means the load does not come back when the fault clears. Operators and balancing authorities must plan restoration around that constraint.

AI training campuses increasingly skip the UPS altogether for IT load. Training jobs checkpoint their state to protected storage; if power fails, the run restores from the last snapshot, and the economics of a campus-scale UPS simply do not justify the training progress it would save. The grid-facing consequence is a facility with even less inherent ride-through than its enterprise cousins — a fact that must be represented honestly in study models.

3.2 Documented Oscillations: The Load as a Source, Not a Victim

The most consequential field evidence in the recent industry literature concerns oscillations that originate inside data centers. In one documented test program, an operator brought a full complement of servers to load and then idled them synchronously. At high load, a fleet of forty UPS units arranged in twenty pairs began to oscillate, with the onset point governed by feed inductance and unit loading. Removing one UPS pair from the utility feed — reducing the effective impedance seen by the remaining pairs — stopped the oscillation. The behavior was replicated in simulation and in factory testing with the manufacturer by representing the utility-side inductance, and the permanent fix was a reduction in the loop gain of the rectifier's power factor correction circuit to restore adequate phase margin.

The same operator later encountered a second, distinct instability in a power supply PFC stage — this one appearing at sites both with and without UPS units, at much higher frequency, in the ninth-to-eleventh harmonic range, and resolved through a vendor firmware change to the rectifier control. In a separate case, oscillations were triggered not by anything inside the facility but by the utility removing one of two parallel transformers, raising the source inductance feeding the UPS fleet.

Three lessons follow. First, converter-driven instability on the demand side is real, measured, and sensitive to grid impedance — meaning it is a function of the interconnection, not just the equipment. Second, models that omit the UPS PFC stage cannot screen for the phenomenon; positive-sequence phasor-domain models alone are structurally blind to it, which is why EMT representation of the power conversion chain is becoming a study requirement for large facilities in low short-circuit-ratio areas. Third, high-resolution monitoring — phasor measurement units and digital fault recorders at the point of interconnection and within the facility — is the only way operators gain situational awareness of these interactions before they propagate.

Keentel Insight

Every one of these documented events was diagnosed, replicated, and corrected through the combination of field measurement and validated EMT modeling — the same discipline the industry spent a decade building for inverter-based generation. Developers who invest in facility-level EMT models during design, rather than after an event, protect both their energization schedule and their neighbors on the grid.

3.3 Architectures in Motion: From 415 V AC to 800 V DC

Rack power density is forcing a redesign of the entire internal distribution chain, and each architecture generation changes the facility's dynamic signature at the point of interconnection. The conventional design delivers medium voltage to a step-down transformer, through a double-conversion UPS, to in-rack power supplies converting roughly 415/480 V AC to 54 V DC. The Open Compute Project's ORV3 generation moves the battery backup function into the rack alongside the power supply. As machine-learning racks head toward 500 kW and beyond, the industry is standardizing on 400 V DC distribution: a "sidecar" power rack takes in low-voltage AC, converts it to 400 V DC, and distributes it to adjacent compute racks, where DC/DC converters step down to 54 V. Full-bridge LLC resonant conversion inside 18 kW power supply modules, combined six to a shelf, enables roughly 400 kW per rack.

The next step is building-level DC. In the "Northstar"-class architecture, a solid state transformer — or a large rectifier — converts medium voltage AC (11 kV to 35 kV) directly to 400 V DC at the facility level, eliminating conversion stages. Nvidia has proposed an 800 V DC ecosystem for AI factories supporting megawatt-class racks: 13.8 kV AC is converted to 800 V DC at the data center perimeter, transmitted via busway through the halls, and stepped down to 54 V/12 V inside the rack, carrying substantially more power through the same conductor cross-section and shedding multiple AC/DC stages along the way.

For the power system engineer, each of these designs changes what must be modeled. The sidecar converter, the solid state transformer, the facility-level rectifier, and even the final DC/DC stage each contribute to the facility's fault response and its harmonic and oscillatory potential. Solid state transformers in particular are active power-electronic devices with their own control loops — coupled with storage, they can be engineered to deliver ride-through, which makes them both a modeling obligation and a compliance opportunity. Study models built for the conventional architecture cannot simply be reused for a 400 V DC or 800 V DC facility.

3.4 Cooling: The Quiet Ride-Through Liability

Cooling can consume 30 to 40 percent of a data center's electricity at the top of the range, and nearly every fan and pump in a modern facility is driven by a variable frequency drive or electronically commutated motor. VFDs carry their own ride-through settings, programmed independently of the IT equipment — and a cooling system that trips during a fault will force the compute floor down minutes later regardless of how well the servers rode through. Facility ride-through is therefore a chain with two links, and the weaker one governs. VFD parameters at large facilities should be reviewed and set so that normally cleared faults do not remove cooling, and facility-level models must represent the cooling drives, not just the IT power chain. Cooling design also drives PUE and therefore the total energy forecast the interconnecting utility must plan around.

4. AI Workloads: The Most Dynamic Load Ever Connected

AI campuses share the physical building blocks of conventional data centers, but their workloads produce electrical behavior with no precedent at this scale. The distinction begins with the silicon: GPU clusters optimized for matrix mathematics operate in large, synchronized groups, and that synchronization stamps itself onto the facility's power draw.

Training is the extreme case. The backpropagation cycle that dominates model training alternates between phases — a forward pass that spikes compute demand, a loss calculation that relaxes it, a backward pass that spikes it again, and a weight update that relaxes it — and the facility's aggregate load follows this rhythm in a repetitive sawtooth. Training campuses idle at roughly 60 to 70 percent of peak simply to maintain readiness, then swing between partial idle and full load as jobs progress. Because a synchronized training job requires every node, a single machine failure halts the entire run: 30 to 50 percent of active facility load can vanish within microseconds, then return as the job auto-reconfigures and restarts — a cycle that can repeat tens of times per day. At the individual GPU the power step is nearly instantaneous, though the supporting power supply's capacitance and control loops stretch the facility-level ramp to roughly fifty milliseconds.

Inference is gentler but far from benign. Its baseline is low, punctuated by request bursts that swing the load between idle and near-peak; aggregate inference fleets have exhibited power reductions of 80 to 90 percent in under a second. Fine-tuning sits between the two. And the trend line is adverse: rack-level measurements comparing prior-generation and current-generation GPUs show that power-swing potential is growing with each hardware generation, driven in part by liquid-cooled GPU architectures. Aggregation across racks and modules reshapes but does not eliminate the variability seen at the point of interconnection.

Distributed deep learning adds a systemic dimension. Training jobs now span multiple campuses — sometimes in different balancing areas. When one participating site experiences a grid fault and trips, it signals its partners to pause, and multiple multi-hundred-megawatt facilities may reduce demand together. A coordinated, effectively instantaneous loss of several gigawatts of load is an over-frequency event of the first order: it can force generators to run back or trip, and in the extreme, cascade. Planning coordinators need to treat correlated multi-site load loss as a studied contingency, not a hypothetical — and the size of that contingency is a moving target as training fleets grow.

The variability question ultimately becomes an oscillation question. Repetitive training cycles at the wrong frequency, at gigawatt scale, constitute a forced oscillation source that can excite inter-area modes or torsional modes at nearby synchronous machines. Frequency-domain screening of the facility's expected load spectrum against known system modes belongs in the interconnection study scope for any large AI campus.

4.1 The Flexibility Toolbox

The same characteristics that make AI training disruptive also make it the most promising flexibility resource among large loads. Training is an offline process without enterprise latency commitments: it can pause, throttle, and resume. A 2025 field demonstration in Phoenix by Emerald AI, Nvidia, the Salt River Project, and EPRI showed software-based load shaping using job pausing and dynamic frequency scaling of GPU clocks and voltage. Google has published compiler-level techniques that schedule and balance training jobs across time to smooth power flow, and non-critical jobs can be shifted to data centers on entirely different power systems as a form of demand response.

Hardware complements software. Supercapacitor systems — rack-mounted or facility-level — absorb and inject power over millions of cycles with response speeds that bridge the gap between server power supplies and the UPS, smoothing transients before they reach the grid; commercial offerings now span rack-mounted supercapacitor shelves to transmission-class E-STATCOM solutions. Battery systems, including containerized megapack-class units, add energy depth for longer smoothing horizons and steeper swings. In our assessment, code-level and scheduler-level mitigation is the least capital-intensive first line, with capacitive and battery hardware sized against whatever residual variability the software cannot remove — and the interconnection agreement should specify the performance the combination must achieve at the POI.

Flexibility has limits, and contracts define them. Colocation facilities carry customer uptime obligations, and in multi-tenant buildings the tenant, not the operator, controls the compute — and therefore the megawatts. Grid programs that assume the facility operator can curtail on request will fail at exactly the facilities where contracts say otherwise. Flexibility must be engineered and contracted at interconnection, not assumed afterward.

5. Cryptocurrency Mining: The Price-Following Gigawatt

Cryptocurrency mining is the purest economic load on the grid: an arbitrage that converts energy into currency. That single fact explains nearly all of its electrical behavior. Facilities are built lean — thousands of single-phase ASIC rigs fed through step-down transformers from a 34.5 kV-class distribution intertie, with no UPS and no backup generation, because every dollar of resilience equipment erodes a business that typically returns 20 to 40 percent on investment. Auxiliary load for safety, security, and environmental control runs only 1 to 5 percent of the facility.

Under normal conditions miners run flat out, targeting fleet PUEs as low as roughly 1.04, with load shaped mainly by ambient temperature's effect on cooling. But when energy prices rise above the value of the coin being mined, the load simply leaves. Most large miners in ERCOT participate in Load Acting as a Resource, others clear demand response day-ahead, and essentially all self-curtail on price. Facilities can typically shed to 20 percent of load on request — 5 percent if pressed — and can traverse from near-zero to full load in anywhere from 20 seconds to 20 minutes. Restoration after a trip or curtailment is similarly fast, usually within about 20 minutes as cooling systems re-establish. For the balancing authority, this is a load whose short-term forecast error is driven by commodity prices and whose ramps rival utility-scale batteries — which, not coincidentally, are the resource best suited to buffering them.

Ride-through behavior tracks the ITIC curve, with real hardware measured close to — and in places short of — its boundaries. Experimental testing of a widely deployed ASIC model demonstrated continuous operation from 66 to 130 percent of rated voltage, but a zero-voltage withstand of only 9.5 milliseconds against the 20 milliseconds contemplated by ITIC. Ride-through capability is set by on-board capacitor sizing, and retrofitting deeper capability is economically unattractive; ERCOT has already logged multiple events in which fleets of miners failed to ride through disturbances and dropped in unison, perturbing system frequency.

Simulation work has also shown that harmonic interaction with nearby inverter-based resources — a solar plant, in the published case — can trip mining power supplies in low short-circuit-ratio areas. VFD-driven cooling adds a second trip path: a documented facility tripped three times on single-phase voltage sags before its VFD ride-through parameters were corrected.

Power quality closes the picture. ASIC fleets present a leading power factor near 0.99 and emit characteristic triplen harmonics. With a delta-grounded-wye interconnection transformer, the delta winding traps triplen currents and the transmission system sees compliant distortion — measured facilities have recorded voltage THD near 4.3 percent and current THD near 9.2 percent, inside IEEE 519 limits. Without the delta winding, third and fifth harmonic injection can exceed IEEE 519 and demand filtering. Transformer vector group selection, harmonic screening against IEEE 519, and permanent power quality monitoring at the POI are therefore baseline interconnection requirements for mining facilities, not optional extras.

Keentel Insight

Mining interconnections succeed or fail on three studies: a harmonic assessment that reflects the actual substation transformer vector group, a ride-through review that treats the ITIC curve as a proxy pending vendor data, and an operational characterization that gives the balancing authority honest ramp and restoration parameters. All three are inexpensive relative to the cost of a post-energization mitigation retrofit.

6. Hydrogen Electrolysis: The Electrochemical Large Load

Electrolytic hydrogen remains a small fraction of global production today, but electrolyzer capacity is compounding — global installed capacity reached 1.4 GW in 2023, doubling in a single year, with several times that reaching final investment decision since. Individual projects now enter interconnection queues at 100 MW-plus, built up from modular stacks, and their electrical character differs fundamentally from the compute loads above: the constraint is electrochemistry, not silicon.



The facility's load anatomy is dominated by the stack itself, with the balance spread across conversion, compression, water treatment, and cooling. The rectifier plant is the grid interface and the design decision that matters most for power quality: large facilities have historically used thyristor-based silicon-controlled rectifiers in 6-, 12-, or 24-pulse configurations — robust and cost-effective at high power, but heavy consumers of reactive power, exposed to commutation failure, and reliant on pulse multiplication or DSTATCOM-class mitigation to control characteristic fifth and seventh harmonics. IGBT-based rectifiers deliver better harmonic performance, power factor, and weak-grid behavior, and are gaining share, though with current limits that constrain them at the largest stack ratings, higher switching losses, and higher cost. Paired rectifier transformers with staggered vector groups are the standard tool for canceling low-order harmonics and smoothing DC ripple to the stacks.

Four electrolyzer technologies define the design space. Alkaline units are the mature workhorse, preferred at stable baseload, with liquid electrolytes that slow their response. PEM units use solid polymer membranes and respond fast enough to track renewables and provide frequency service. Solid oxide cells run hot on steam with strict thermal management, and anion exchange membrane technology aims to combine PEM-class response with alkaline-class capital cost. The operating envelope follows the chemistry: PEM ramps on the order of 1 to 20 percent of DC current per second, alkaline more like 0.5 to 2 percent per minute; warm starts recover full load in roughly 5 to 30 minutes while cold starts run from a few minutes for PEM to an hour or two for alkaline; and alkaline plants carry a hard minimum turndown — typically 5 to 25 percent — below which hydrogen-oxygen crossover creates an explosive safety limit, not merely an efficiency preference.

Demonstrations have established that electrolyzers can deliver real grid services: sub-second setpoint following, primary frequency response in both directions, synthetic inertial response, and reactive power support have all been shown in laboratory hardware-in-the-loop environments and at operating megawatt-scale plants. Whether those capabilities are compensated as ancillary services or mandated through interconnection requirements is a jurisdictional question — but the technical capability exists, and facility control hierarchies can be architected for it from day one.

Ride-through is the open frontier. Unlike computer loads with their de facto ITIC basis, electrolyzer facilities have no unified ride-through standard; capability is limited by the electrochemical process behind the stack rather than by the converters, jurisdictional requirements vary, and published example envelopes — riding through deep sags for tenths of a second and wide frequency bands for defined durations, with post-fault recovery ramps around 10 to 15 percent per second — are illustrative rather than prescriptive. Supplementary storage can extend capability at a project-specific cost. Interconnection agreements for hydrogen must therefore negotiate ride-through explicitly, informed by the specific stack technology, rectifier design, and safety chain — a genuinely bespoke engineering exercise on every project.

7. What This Means for Interconnection Engineering

Pull the threads together and a clear engineering agenda emerges for any party interconnecting — or hosting — a large load.

Modeling must reach inside the fence. Positive-sequence dynamic models remain necessary for planning studies, but they cannot capture rectifier PFC instability, harmonic interaction with nearby inverter-based resources, or sub-cycle trip behavior. For large facilities, especially in low short-circuit-ratio regions, validated EMT models representing the actual power conversion chain — UPS stages, sidecar converters, solid state transformers, VFD-driven cooling, rectifier plants — are becoming the standard of care, exactly as they did for inverter-based generation. Where the facility transfers to backup generation, minimum run times belong in restoration modeling.

Performance requirements must be written from the grid's perspective. The ITIC curve is a design convention, not a reliability standard. Utilities and ISOs are moving to dedicated large-load ride-through requirements, harmonic limits enforced at the POI under IEEE 519, oscillation screening, and telemetry obligations including PMU-class monitoring. Developers who engage these requirements at design — selecting transformer vector groups, specifying VFD ride-through parameters, sizing supplementary storage, architecting control hierarchies — interconnect faster and cheaper than those who retrofit.

Flexibility should be engineered, not assumed. AI training, crypto mining, and electrolysis each offer genuine flexibility, but bounded by contracts, chemistry, and economics respectively. The honest path is to characterize what the facility can actually deliver — ramp rates, notice requirements, minimum loads, restoration times — and embed it in the interconnection agreement and market registration.

Keentel Engineering works both sides of this problem: for developers, we prepare interconnection applications, facility one-lines, PSS/E and PSCAD/EMTDC models, ride-through assessments, harmonic and oscillation studies, and NERC compliance programs; for utilities and owners, we serve as owner's engineer reviewing large-load interconnection requests, drafting performance requirements, and validating the models submitted to us. Gigawatt-class loads are the defining interconnection challenge of this decade. The engineering to integrate them reliably exists — it simply has to be applied early, and applied well.
