Energy audit recommendations deliver savings only when ranked by payback: no-cost fixes first, then LED, VFD and controls retrofits, then major equipment. LED retrofits typically cut lighting energy by 50–60%, with payback often within one to two years, according to BEE and EESL programme data. Variable frequency drives on variable-load pumps and fans commonly save 20–50% of motor energy, per BEE energy auditor guidebooks. A Chennai manufacturing unit replacing 600 fittings of 72 W with 36 W LEDs saves about 21.6 kW; at 4,000 hours a year and ₹8 per kWh that is roughly ₹6.9 lakh annually. Adding VFDs to two 30 kW pumps at a 30% saving over 6,000 hours adds around ₹8.6 lakh.
Recommendations should arrive as a costed list: measure, investment in ₹, annual kWh and ₹ saved, payback and CO₂ avoided. Group them into no-cost operational changes, low-cost retrofits and capital projects, and assign owners and dates. Without that structure, audit reports sit on shelves. The sections below show how to turn findings into an implementation plan, how to verify savings with measurement and verification (M&V) and how to stop results from eroding. Owners, dates and review meetings are what turn a report into results.
Rank energy audit recommendations by simple payback and risk: no-cost operational changes first, then LED, VFD and controls retrofits with one to two year payback, then equipment replacement. Assign owners, budgets and dates, and verify savings against a normalised baseline for at least 12 months.
