Renewable Consultancy

Voltage optimisation feasibility for your site.

One of the fastest-payback technologies available. We assess your incoming supply voltage and load profile to tell you exactly how much you can save — without supplier bias.

What's included in your study

UK grid voltage typically runs above the 230V nominal standard. Voltage optimisation equipment reduces this to the optimal level for your equipment, cutting electricity consumption and protecting motors and equipment from over-voltage stress. We analyse your half-hourly data to calculate your specific saving potential.

  • Full cost-versus-savings modelling
  • Payback period and ROI calculations
  • Technology sizing and specification
  • Grid connection and planning assessment
  • Available grants and incentives review
  • Written report with clear recommendations

What we assess

Every feasibility study covers the full picture — we don't cherry-pick the technology, we find what genuinely works for your site.

Site voltage profiling
Measure your actual incoming voltage across the day and week to quantify over-voltage waste.
Load profile analysis
Review half-hourly consumption data to identify the loads that benefit most from optimisation.
Saving calculation
Model the specific kWh and cost saving for your site — not industry averages.
Equipment protection assessment
Identify motors, HVAC and other equipment that benefits from regulated supply voltage.
Equipment specification
Specify the correct unit size and configuration for your site's supply and load.
Payback modelling
Full capital cost, annual saving and payback period calculation — typically 1.5–3 years.

Why businesses choose this

Fast payback

Voltage optimisation typically pays back in under 3 years — one of the fastest returns of any energy technology.

No operational disruption

Installed at the incoming supply — completely transparent to your operations with no changes to equipment or processes.

Equipment longevity

Regulated voltage reduces stress on motors, compressors and other inductive loads, extending equipment life and reducing maintenance costs.
