What We Offer
Engineering services built for the energy transition.
EcoVoltec provides specialist engineering design across the full project lifecycle — from initial feasibility and concept design through to detailed engineering, construction support, and commissioning. Our team works with utilities, developers, EPCs, system integrators, and equipment manufacturers across the US, Caribbean, and Europe.
13 Services
Power System Studies
Network modelling and compliance studies in ETAP, PSS®E, PSCAD/EMTDC and DIgSILENT PowerFactory — scoped to the grid code and standards that govern your connection, from distribution through to transmission.
Load Flow & Voltage Regulation
Steady-state power flow across all operating scenarios — thermal loading, voltage profile, tap and reactive plant settings, and contingency (N-1) performance.
Short Circuit & Fault Level
Three-phase and unbalanced fault duties to IEC 60909 and IEEE 551 / ANSI C37, with equipment make and break rating checks and fault level headroom for new connections.
Protection Coordination & Grid Decoupling
Time-current grading across the full protection chain, relay setting schedules, and interface protection to VDE-AR-N 4110 / 4120 and EN 50549, with reach, sensitivity and discrimination verified from LV to transmission.
Arc Flash & Incident Energy
Incident energy and boundary calculations to IEEE 1584-2018, reported against NFPA 70E or CSA Z462, with PPE categories and equipment labelling.
Harmonics, Flicker & Power Quality
Harmonic penetration, resonance screening and filter design to IEEE 519, IEC 61000-3-6 and AS/NZS 61000.3.6, with flicker to IEC 61000-3-7 and supply quality assessed against EN 50160.

Plant & Unit Certification Support
Certification evidence packages to FGW TR3, TR4 and TR8 — Type A and Type B plant certificates, unit and component certificate review, and the modelling and documentation certifiers ask for.
Fault Ride-Through & Reactive Capability
LVRT and HVRT withstand, reactive power capability at the connection point, and Q(U), cos φ(P) and voltage control mode tuning verified against the applicable connection standard.
Frequency Response & System Strength
LFSM-O/U and FSM frequency response, inertia and fast frequency response contribution, plus short-circuit ratio and system strength impact assessment for inverter-based plant.
Dynamic Stability & EMT Studies
Transient and small-signal stability and control interaction screening, with validated PSS®E (RMS) and PSCAD/EMTDC models prepared for R1 and R2 model submissions.
Motor Starting & Load Shedding
Starting voltage dip and acceleration checks for large motors, plus under-frequency and under-voltage load shedding schemes for islanded and weak-grid operation.
Insulation Coordination & Switching Transients
Lightning and switching overvoltage studies to IEC 60071 and IEEE 1313, surge arrester selection, and transformer energisation and capacitor switching assessment.
Earthing & Ground Grid Studies
Grid resistance, earth potential rise, and touch and step voltage verification to IEEE Std 80 and EN 50522, including soil resistivity interpretation and transferred potential review.
