kVA Analysis and Planning

Lower bills without sacrificing energy usage.

If your kVA level is set too high, you’re overpaying for unused capacity; if it’s too low, you risk exceeding your limit, triggering penalty charges and potentially damaging your equipment. A kVA analysis with Renew & Sustain helps you accurately assess your business’s electrical demands, ensuring your system operates efficiently without overloads or costly surprises. Want to lower operational costs and improve your energy efficiency? Contact us today so we can conduct an energy audit for your business.

kVA Analysis Helps Businesses

Why Our kVA Analysis Helps Businesses

A kVA analysis examines a business’s apparent power demand — measured in kilovolt-amperes (kVA) — to understand how efficiently electrical energy is being used. Unlike kilowatts (kW), which measure actual power consumed, kVA includes both real power and reactive power (which supports voltage stability but doesn’t perform useful work).

For businesses, kVA analysis helps to:

  • Identify peak demand periods that trigger higher energy charges.
  • Assess power factor (the ratio of kW to kVA) to uncover inefficiencies.
  • Avoid unnecessary maximum demand or capacity charges on electricity bills.
  • Optimise electrical load profiles for cost-effective energy procurement.
  • Ensure compliance with utility supply agreements and reduce penalties.

Ray Richardson

The Renew and Sustain team, particularly Joe Edwards, took the time to get to know our business energy needs. He and Dani even took the time to visit our factory even though it’s 150 miles from their base.

Jo Graydon – MCF Recruitment

I would 100% recommend Renew and Sustain.
From a professional point of view as a Recruitment Consultant, Renew and Sustain are an absolute pleasure to work with and a very valuable Client.

A Littlejohn

I spoke to Martin Perry when looking to renew my Electricity supplier. Martin was incredibly helpful and knowledgeable. He was not at all pushy (which is often the case with utility brokers) and was happy that I do things at my pace.

Gillian Hilton

Martin Perry was very helpful and made our transition very smooth and easy. He explained everything in full detail and there were no hidden charges and he got us the best deal on the market.

Paula Kelly

Joe Edwards obtained for us some excellent gas, electricity & water deals. He was extremely quick in his responses to our questions.

kVA Analysis FAQs

kVA Analysis FAQs

kVA stands for kilovolt-amperes and is a measure of apparent power in an electrical system. It represents the total power supplied, including the power that does actual work (kW: kilowatts) and the reactive power (kVAR) needed to maintain voltage levels.

In simple terms, your electricity provider supplies kVA, and you’re often charged based on your maximum demand — the peak amount of kVA your site draws over a given period. This is commonly referred to as a kVA demand charge on commercial electricity bills.

To reduce or avoid excessive kVA demand charges, you can:

  • Monitor and manage peak loads using energy management systems
  • Stagger the start-up of large equipment to prevent demand spikes
  • Improve power factor by installing capacitor banks or power factor correction equipment
  • Conduct load balancing across phases to reduce demand inefficiencies
  • Schedule operations during off-peak periods when possible.

By keeping your kVA demand within your agreed limits, you can avoid costly surcharges and optimise your energy contract.

  • kW (kilowatts) measures real power — the power used to perform work (e.g., lighting, heating, running motors).
  • kVA (kilovolt-amperes) measures apparent power, which is a combination of real power and reactive power (needed to maintain voltage in the system).

The ratio between kW and kVA is called the power factor (kW ÷ kVA). A higher power factor indicates more efficient energy use. Businesses with poor power factors tend to have higher kVA demand and may face additional charges.

A detailed kVA review can help align your procurement with your actual usage profile, reducing both contracted and actual costs. kVA analysis plays a key role in smart energy procurement by:

  • Identifying excess demand that inflates your energy bills
  • Highlighting inefficiencies in load profiles and power factor
  • Helping negotiate better supply contracts by setting realistic maximum demand thresholds
  • Supporting load-shifting strategies to avoid peak time penalties
  • Ensuring right-size supply agreements (avoiding over- or under-capacity).
