An electrical energy audit measures kW, kVA, power factor and harmonics at your incomer and major loads to find wasted units and avoidable charges.
India’s first Perform, Achieve and Trade (PAT) cycle, which depends on audited energy baselines, delivered 8.67 million tonnes of oil equivalent in savings against a 6.686 MTOE target, according to the Bureau of Energy Efficiency (BEE). For power quality, IEEE Std 519 recommends keeping voltage harmonic distortion at or below 8% for systems up to 1 kV.
For example, a Pune engineering plant spending ₹6 crore a year on electricity corrects power factor from 0.88 to 0.98, rebalances transformer loading and fits VFDs on cooling-water pumps. Together these cut consumption and demand charges by about 9%, or ₹54 lakh a year. Against ₹60 lakh of capital spend, payback is about 13 months.
Electrical energy audits differ from electrical safety audits. The first targets losses in kilowatt-hours and rupees, while the second tests installations for shock and fire risk against IS 732 and statutory safety rules. Both start with the single line diagram and 12 months of bills, followed by a walk-through of motors, transformers, capacitor banks and UPS units. Calibrated power analysers then log load over a full production cycle, and the report ranks measures.
An electrical energy audit tests how efficiently your electrical system turns supply into useful work. Auditors log load, power factor, harmonics, transformer loading and motor efficiency, then recommend fixes such as capacitor banks, VFDs and LED retrofits. Fees start near ₹50,000, and most measures pay back within three years.

FAQs
How much does an electrical energy audit cost in India?
Fees range from about ₹50,000 for a walkthrough to ₹15 lakh for an investment-grade audit, depending on connected load, number of feeders and measurement duration. If the audit finds a 9% saving on a ₹6 crore bill, the ₹54 lakh annual saving typically recovers the fee within months.
What does an electrical energy audit include?
Auditors review bills and the single line diagram, then measure load profile, power factor, voltage unbalance, harmonics and transformer loading with calibrated analysers. They test motors, pumps, fans and lighting, scan panels with a thermal camera, and report each measure with investment, saving and payback.
How often should an electrical energy audit be done?
BEE-notified designated consumers must audit through an accredited energy auditor, typically every three years, and file Form 1 and Form 2 with the State Designated Agency within three months of the report. Other facilities should audit every two to three years or after major load changes. Non-compliance can cost up to ₹10 lakh plus ₹10,000 per day.
What is the difference between an electrical energy audit and an electrical safety audit?
An energy audit looks for waste in kWh, kVA and rupees. A safety audit checks wiring, earthing, protection and clearances against IS 732 and CEA safety regulations to prevent shock and fire. They share data such as the single line diagram, so doing both together reduces site disruption and cost.
What are common problems found in an electrical energy audit?
Frequent findings include low power factor, lightly loaded transformers and motors, voltage unbalance, harmonic distortion from VFDs and UPS units, undersized cables, loose joints and lighting left on. Fixes include automatic capacitor banks, right-sizing, harmonic filters, cable upgrades, torque checks and occupancy-based lighting controls.
