Dynamic model validation, protection coordination, short circuit, arc flash, transient stability and EMT studies — bankable, regulator-accepted, simulator-ready.
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.
Interconnection studies and regulator-mandated model submissions. Protection coordination for new installations. Arc flash for safety compliance.
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.
Design verification — short circuit, load flow, arc flash, protection coordination — for handover to the owner. Independent third-party studies preserve the acceptance gate.
Third-party validation of equipment models and design assumptions when regulators or lenders require independence from the supplier.
Independent verification of the studies underwriting non-recourse project finance — interconnection feasibility, protection design, dynamic model bankability.
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.
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.
Relay setting calculations, selectivity verification, time-current curves, primary & backup logic. From medium-voltage plant networks to transmission-tie protection.
Three-phase and unbalanced fault levels, equipment rating verification, contribution analysis from all sources including IBRs. Load flow under normal and contingency conditions.
Incident energy calculation, PPE category assignment, labeling per code. The deliverable that drives operator safety procedures and labeling — and that auditors read first.
Large-disturbance behavior under faults, generation trips and grid contingencies. Ride-through assessment, frequency excursion analysis, first-swing and oscillatory stability.
Electromagnetic transient analysis — switching surges, lightning, sub-synchronous interactions, IBR control interaction. EMTP-native work for the studies that frequency-domain tools cannot answer.
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.
Study type confirmation. Standards selection. Regulator format. Simulator platform decision.
Single-line diagram. Equipment parameters. Control models. Field data acquisition for model validation work.
Simulation runs across the contingency set. Sensitivity analysis. Iterative tuning for model validation engagements.
Findings, recommendations, narrative report plus native simulator files. Regulator-submission format when applicable.
Stand behind findings through regulator, EPC and lender review. Setting implementation support for protection work.
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.
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.
International accreditation for inspection bodies. The credential international lenders and DFIs recognize for independent third-party verification.
Native fluency across the four simulators regulators, planners, EPCs and protection engineers actually use. Studies delivered in the format your downstream consumer can drop in and run.
Active engagement at CCC Dulces Nombres, operated by Energía Quantum in Mexico. A complete grid code campaign on the newly installed AVR and the speed governor has just closed; the dynamic models are now being updated to reflect the retrofit configuration.
EMTP and PSS®E model updates in progress — parameter identification driven directly off the measured AVR and governor response from the just-closed test campaign. Targeting regulator submission on completion.
Grid code testing on the new AVR and the speed governor closed in advance. The model update follows directly off the measured response — the EMTP and PSS®E parameters being identified against real field data, not OEM defaults. Regulator submission package authored end-to-end in-house.
