01
Diagnostics, efficiency optimization and reliability improvement of the existing installations of a cogeneration plant.
02
Diagnostics, routine testing and condition monitoring of three-phase power transformers: dielectric measurements, oil analyses and preventive maintenance plans.
03
Design and installation of a photovoltaic system with lithium storage keeping a residential building powered during grid outages: load assessment, sizing, installation and commissioning.
04
On-site inspection of electrical installations and equipment: compliance check against applicable standards, insulation and continuity testing, followed by a conformity report with corrective recommendations.
05
Integration studies of a containerized battery energy storage system (BESS): auxiliary power and communication diagrams, SCADA/Ethernet architecture and supervisory interfaces.
06
Interface diagrams and functional testing of a battery storage system's safety chains: fire detection, combustible gas alarms, emergency stop and protection interlock logic.
07
Protection coordination and arc-flash study of an industrial grid: short-circuit calculations, selectivity and coordinated settings of digital relays on MV and LV feeders.
08
Transient recovery voltage (TRV) study of a generator circuit breaker: modelling of the generator–transformer section, fault-current calculations and verification of the breaker's capability.
09
Selectivity verification and coordination of digital relays on an MV grid: plotting and analysis of time-current curves (TCC), protection settings and validation of coordination margins.
The same standard applies to every assignment, from on-site survey to skills transfer: reproducible, auditable and quantified engineering.
Single-line diagrams, field surveys, operating conditions, short-circuit levels and client-specific constraints.
Power flow, IEC 60909/61363 short-circuit, transient stability, N-1 contingencies and protection coordination.
Normal and degraded modes, load growth, EnR/storage/EV, technical trade-offs and economic analysis of the variants.
FAT/SAT testing, relay settings, operating procedures and capacity building for local teams.
A glimpse of our assignments carried out in the field, from Québec to Africa.




























Every assignment mobilizes a complete technical chain, from feasibility study to skills transfer.
Protection sizing and verification according to IEC 60909 and 61363.
Circuit breaker and relay settings, protection schemes with no cascading tripping.
DIgSILENT, ETAP, PSS/E: power flow, transients and N-1 contingencies.
Hybrid architecture, energy management, black-start and islanded mode (IEEE 1547).
