Design & Consultancy
The most expensive problems in a power project are the ones designed in at the start. PES provides the engineering studies and design work that settle those questions on paper before equipment is ordered and before anything is installed. Our consultancy services cover load flow and fault level studies, PV/generator/grid interface scheme design, transformer and cable sizing, and power factor improvement (PFI) bank sizing. Together these underpin sound, standards-compliant designs for solar and hybrid renewable energy projects, carrying a scheme from initial feasibility right through to detailed engineering.
What we deliver
Load Flow Studies
Modelling how power actually moves through your network under real operating conditions. Load flow analysis reveals voltage profiles, loading levels, and losses across the system confirming the design holds up before it’s built, and identifying constraints while they’re still inexpensive to resolve.
Fault Level Studies
Calculating prospective fault currents at every point in the network so equipment is correctly rated and protection is properly coordinated. Fault level analysis is what ensures switchgear can safely interrupt what it may one day be asked to interrupt.
PV / Generator / Grid Interface Scheme Design
Scheme design for the points where sources meet solar, generation, and the utility grid. We engineer the interface architecture, control philosophy, and protection scheme that let these sources operate together safely and predictably, supported where required by grid impact studies.
Transformer & Cable Sizing
Correct sizing of transformers and cabling based on calculated loads, fault levels, voltage drop, and thermal limits. Getting this right avoids both the cost of over-specification and the far greater cost of equipment operating beyond its capability.
Power Factor Improvement (PFI) Bank Sizing
Sizing PFI banks to correct power factor and reduce reactive demand cutting utility penalties, freeing up network capacity, and improving voltage stability across the installation.
From Feasibility to Detailed Engineering
A continuous design thread from first feasibility assessment through to full detailed engineering, including electrical balance of plant. Every deliverable is standards-compliant and produced under our ISO 9001-certified quality management system so the engineering intent that starts the project is the same intent that reaches commissioning.
