ASSESS BEFORE SELECTING
Build the decision on representative site evidence
A site assessment determines whether voltage optimisation is technically credible, operationally acceptable and commercially material. It should also identify when not to proceed.
What we review
- Single-line diagrams, transformer and switchboard data, protection settings and earthing arrangements
- Voltage at representative points, by phase and time
- Energy, power, demand, operating schedules and material drivers
- Load inventory and voltage-response categories
- Remote, sensitive and critical loads
- Solar PV, batteries, UPS, VSDs, power-factor equipment and existing regulators
- Planned expansions, EV charging and portfolio constraints
Typical monitoring period
The duration is selected to capture representative operating states. A short survey may screen a stable site; a facility with seasonal, production or weather effects may require a longer interval model and additional operational data.
Assessment outputs
- Voltage and load profile
- Suitability and risk findings
- Recommended control strategy and electrical boundary
- Minimum-voltage and rating basis
- Conservative net-savings estimate with assumptions and sensitivity
- Outline business case and delivery constraints
- Proposed M&V and commissioning approach
- Proceed, investigate further or do-not-proceed recommendation
- Information to prepare
Recent electricity data, site operating hours, major-load information, single-line diagrams, known power-quality issues, generation/storage details and planned load changes help accelerate the assessment.
