Power System Studies & Simulation.
Power system studies for new projects and operating assets. We assess load flow, short circuit, protection coordination, arc flash, power quality and grid integration against the agreed project basis, helping your team make decisions during planning, design, commissioning and operation.
Project location, local requirements and any site support are confirmed for the agreed scope.
Explore Global DeliveryEngineering Scope.
Twelve studies. Each one answers a single question, before equipment is bought.
Load Flow
Can the network carry the load in every operating case?
Short Circuit
Is every piece of equipment rated for the worst fault?
Relay Coordination
Will protection isolate a fault fast, and only where it should?
Arc Flash
What is the hazard at each switchboard, and the PPE it needs?
Earthing
Is the site safe for people during an earth fault?
Harmonics & Power Quality
Will distortion overheat equipment or breach utility limits?
Transient Studies
What happens in the milliseconds after a switch, fault or strike?
Insulation Coordination
Are insulation levels and arresters right for the overvoltages?
Motor Starting
Will large motors start without pulling the voltage down?
Grid Code Compliance
Will the utility approve the connection first time?
Battery Sizing
How much storage, at what power and for how long?
Microgrid Simulation
Does the system stay stable once it separates from the grid?
Also available: contingency and reliability, dynamic RMS simulation, stray current, traction harmonics, EV charging load impact, and N+1 / 2N redundancy for critical facilities.
At Each Project Stage.
Where you are in the Project decides what you need from us.
Feasibility & Concept
Validate viability and size the system before capital is committed.
- Load flow and network performance
- Renewable and BESS grid integration feasibility
- Techno-economic sizing basis
Detailed Design
Set the ratings and settings the whole design depends on.
- Short circuit and protection coordination
- Arc flash hazard analysis
- Insulation coordination and transients
- Harmonic and grid code compliance
Tender & Procurement
Confirm equipment ratings match the studies before you order.
- Equipment rating verification against study results
- Technical bid review
Construction
Studies are frozen; site queries reference them, not repeat them.
- Design-basis clarifications
- Settings confirmed for panel and relay ordering
Pre-Commissioning & Commissioning
Prove the settings on the real network before energisation.
- Relay setting verification support
- As-built model reconciliation
Operation & Maintenance
Re-study as the network, load or standard changes.
- Arc flash re-study, typically every 5 years
- Studies for retrofits, expansions or new loads
- Harmonics and power quality troubleshooting

How We Assure the Work
Questions Clients Ask.
Which studies do you carry out?
Load flow including time-series load flow, short circuit, relay coordination, arc flash, harmonics, transient stability and electromagnetic transients, insulation coordination, grid code compliance, battery sizing, microgrid simulation, earthing and motor starting.
Can you prepare grid connection studies?
Yes, renewable and BESS integration and grid code compliance studies for the connecting utility.
Can you study an existing plant?
Yes. Arc flash, protection and harmonic studies are often the first step to a safer plant.
