What is the objective of energy audit?

The objective of an energy audit is to find where energy is used and wasted, then recommend cost-effective measures that reduce consumption and cost.

Section 2(i) of the Energy Conservation Act, 2001 defines an energy audit as verification, monitoring and analysis of energy use, with a technical report containing recommendations, a cost-benefit analysis and an action plan. The Bureau of Energy Efficiency reports PAT Cycle I industries saved 8.67 MTOE against a 6.686 MTOE target.

Consider a 300-bed hospital in Chennai paying ₹6 crore a year for electricity and fuel. A ₹3.5 lakh audit finds 12% savings in chillers, boilers, lighting and pumps, worth ₹72 lakh a year, with ₹95 lakh of measures repaying in about 16 months.

The objective breaks into five goals: establish an energy baseline, identify losses, quantify savings in kWh and rupees, rank measures by payback, and support compliance. Audits come in three levels. A preliminary or walk-through audit uses bills and a site visit. A detailed audit adds instrument measurements and equipment testing. An investment-grade audit adds the financial analysis lenders need. Designated consumers must audit every three years through an accredited energy auditor, while other organisations choose the level that fits their size and budget.
