Domestic Voltage Optimisation (DVO) is an energy-saving technology used to reduce the voltage supplied to electrical equipment to the optimal level for efficient operation. often with the aim of saving energy, extending appliance life, and lowering electricity bills. Here's a breakdown of what it involves:

How It Works...

Most electrical grids supply voltage at levels higher than needed—typically 230V to 250V, while most equipment in the UK is designed to operate optimally at 220V. VO systems reduce this voltage to a more efficient level, usually through a transformer-based device.

Benefits of Domestic Voltage Optimisation

Energy Savings: Typically, 5%–15% reduction in electricity use.
Cost Reduction: Lower energy bills.
Extended Equipment Life: Reduces wear and tear on devices.
Lower Carbon Emissions: By using less electricity.

Limitations of Domestic Voltage Optimisation

Not effective for all loads: Especially resistive loads like heaters or incandescent lighting.
Upfront cost: May take a few years to pay back through energy savings.
Not a substitute for energy efficiency measures like LED lighting.
