5. 253V 242V 207V 220V What is Voltage Optimisation?
Voltage Optimisation is the concept of reducing the incoming voltage from the grid to achieve the optimum voltage for your equipment.
253V
Maximum level supplied by the grid
242V
The average level supplied by the grid in UK
220V
The optimum voltage for equipment efficiency
207V
Minimum level supplied by the grid

6. Why Voltage Optimisation?
Improve Energy Efficiency
Reduce kWh Consumption
Reduce Electricity Costs
Reduce Capital Expenditure
Reduce Carbon Emissions

7. The Technology
To evaluate the potential of installing VO, we identify the types of load on site and categorise:
VOLTAGE DEPENDENT: An electrical device whose power consumption varies with the voltage being supplied to it
VOLTAGE INDEPENDENT: An electrical device whose power demand, within it’s designed operating range, is independent of supply voltage

8. Voltage Dependent Loads
Discharge Lighting
240V Halogen Lighting
Fluorescent Lighting Magnetic Ballasts
Refrigeration Loads
Chillers
AHU’s
Ventilation Systems (without invertors or VSD’s)
Motors/Pumps (without invertors or VSD’S)
Lifts/Escalators (without invertors or VSD’s)
Savings will vary on these types of loads. Lighting will offer 2% reduction in kWh per 1% reduction in voltage, whereas motors may only offer somewhere between 0.8% - 2% per 1% reduction, depending on motor size, how heavily it is loaded. Basically smaller lightly loaded motors offer higher savings than larger motors.
Manufacturing Machinery (without invertors or VSD’s)

9. Voltage Independent Loads
LV Lighting
Electronically Controlled Lighting
Any motor load with invertors or VSD’s
Electric Heating
IT Equipment
Other electrical equipment

10. The Evaluation Process
To evaluate the effectiveness of VO, we require:
Energy usage HHD or Electricity Bills
Maximum Demand
Kwh Rate, (pence per unit)
From this, we can do a quick desk-top survey and to provide indicative quote.

11. Indicative Quote - Example

12. The Evaluation Process
If this is of interest, we will do a full site survey to:
Log the Voltage over 7 days
Survey the site for the load profile and installation
From the information gathered, we would then provide a firm proposal detailing the size and type of equipment, together with relevant warranties, actual savings and guarantees.
