/ 01 · Who this is for

For the teams who need defensible numbers.

Power system studies are the work behind every confident engineering decision in a power plant or interconnection — the protection settings that have to be selective, the short-circuit currents the switchgear has to interrupt, the models the grid operator will use to dispatch the asset for the next twenty years.

Our clients fall into five archetypes. Each one needs the same thing in the end: a study that survives review and produces correct decisions.

/ A

IPPs & Developers

Interconnection studies and regulator-mandated model submissions. Protection coordination for new installations. Arc flash for safety compliance.

/ B

Utilities & ISOs

System-planning models, dispatch tools, transient stability studies. Protection retrofit programs across fleets. The models utilities use to plan must reflect what the fleet actually does.

/ C

EPC Contractors

Design verification — short circuit, load flow, arc flash, protection coordination — for handover to the owner. Independent third-party studies preserve the acceptance gate.

/ D

OEMs

Third-party validation of equipment models and design assumptions when regulators or lenders require independence from the supplier.

/ E

Lenders & DFIs

Independent verification of the studies underwriting non-recourse project finance — interconnection feasibility, protection design, dynamic model bankability.

/ 02 · Six study disciplines

One practice. Six disciplines. One regulator-ready package.

Power system studies cover six related but distinct disciplines. Most engagements combine three or four — for example, a new interconnection might bundle short-circuit, load flow, protection coordination and dynamic model validation in a single mobilization.

Each study is authored against the international standard the regulator and the lender will be reading. Native simulator files are delivered alongside the narrative report.

Where the work livesSubstation & plant interconnection · Studies that survive regulator review
/ 01

Dynamic model validation

PSS®E, DIgSILENT and EMTP models tuned against measured field data. AVR, governor, synchronous machine and IBR control models. Delivered in the regulator's accepted format.

IEEE 421.5 · IEEE 1110 · IEC 61400-27 · NERC MOD-026/027

Protection coordination

Relay setting calculations, selectivity verification, time-current curves, primary & backup logic. From medium-voltage plant networks to transmission-tie protection.

ANSI/IEEE C37 · IEEE 242 · IEC 60255

Short circuit & load flow

Three-phase and unbalanced fault levels, equipment rating verification, contribution analysis from all sources including IBRs. Load flow under normal and contingency conditions.

IEC 60909 · ANSI/IEEE C37 · IEC 60865
/ 04

Arc flash & hazard

Incident energy calculation, PPE category assignment, labeling per code. The deliverable that drives operator safety procedures and labeling — and that auditors read first.

IEEE 1584-2018 · NFPA 70E · CSA Z462
/ 05

Transient stability

Large-disturbance behavior under faults, generation trips and grid contingencies. Ride-through assessment, frequency excursion analysis, first-swing and oscillatory stability.

EMT studies

Electromagnetic transient analysis — switching surges, lightning, sub-synchronous interactions, IBR control interaction. EMTP-native work for the studies that frequency-domain tools cannot answer.

/ 03 · How we deliver it

Five phases. Auditable at every step.

Every engagement follows the same disciplined methodology, scaled to the study scope. Each phase produces specific deliverables that gate the next. The findings that ship at the end are traceable back through data, model, and assumption — line by line.

This is the methodology that survives regulator planning-team review, EPC scope debate and lender due diligence.

/ 04 · Tools & standards

Four simulator platforms. One discipline.

Power system studies live in the simulator. The cross-platform competence is the rare part — most firms know one tool deeply and the others by reference. We work natively in PSS®E, DIgSILENT PowerFactory, EMTP and ETAP, and we move parameters between them when the engagement calls for it.

Model validation engagements also require calibrated field instrumentation — the tuning data that anchors the simulator parameters has to come from measured plant response, not OEM defaults.

Field measurement (validation work)

  • High-speed digital recorders (synchronous capture)
  • AVR / governor control-signal taps
  • Voltage & current probes (calibrated)
  • GPS-synchronized timing
  • Power & energy quality analyzers
  • Field-tested connection accessories

Simulation platforms

  • Siemens PSS®E (.dyr / .idv)
  • DIgSILENT PowerFactory (.dz / .pfd)
  • EMTP — electromagnetic transients
  • ETAP — protection, arc flash, load flow
  • OEM user-defined models (CIM / IBR)
  • Cross-platform parameter porting

Standards we work to

  • IEEE 421.5 · 1110 · 1584 · 2030
  • IEC 60909 · 60865 · 60071 · 61400-27
  • ANSI/IEEE C37 · IEEE 242 · IEC 60255
  • NERC MOD-026 / 027 · TPL-001
  • NFPA 70E · CSA Z462 (arc flash)
  • Local grid codes (CENACE, ONS, CEN, CAMMESA, XM, COES)
/ 05 · Accreditation & standards

Credentialed for regulator, EPC and lender review.

ISO/IEC 17020 accreditation as a Type A inspection body is in progress, expected to complete in 2026. The methodology and the cross-platform competence already meet the technical requirements — accreditation formalizes what is already in place.

Studies are tested against international engineering standards in every jurisdiction we operate. Local grid codes are overlaid as required — never substituted for the engineering baseline.

Services that complete the picture.

Power system studies rarely arrive alone. Most engagements combine studies with adjacent disciplines — grid code testing that provides tuning data for model validation, BESS compliance that requires interconnection studies, regulator filings authored alongside the studies that feed them.
