What is voltage optimisation?

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.

Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.

These systems have recently been installed in MK Building, MA Building and Randall Lines student accommodation, the estimated annual savings are 456,725kWh, equivalent to £45,672 and a carbon reduction of 312 tCO2 p.a. The calculated payback period is 4.46 years.

What are variable speed drives?

Location SA, Telford

MX Building We have installed a variable speed drive on the cooling system with flow and return temperature monitoring to match the load requirements of the building rather than exceed it

Cost: £4,000

Payback (in energy savings) 1.8 years

Carbon saving 12.9 tCO2
