Voltage Optimisation & Regulation

Environment & Energy Management

Voltage Optimisation & Regulation

The average voltage across the UK is 242V. Reducing the voltage supplied to electrical equipment to its optimum level saves energy, reduces maintenance costs and increases equipment lifespan. Fixed reduction units typically provide an 8% reduction.

New legislation such as the Climate Change Levy and Energy Efficiency Carbon Reduction Commitment (EECRC) has resulted in pressure for organisations to reduce their energy consumption and Carbon Emissions. With increasing emphasis on this many businesses are turning to Voltage Optimisation & Regulation as a way to achieve this. Voltage Optimisation & Regulation can result in the following benefits:

  • kWh & CO2 reduction
  • Harmonic filtration
  • Reduced kVA & Agreed Service Capacity charges (ASC)
  • Intelligent voltage optimisation & regulation
  • Efficient, clean & protected power supply
  • Automatic & manual by-pass switch
