Introduction
Elion Technologies and Consulting Pvt. Ltd recently executed a significant project involving a comprehensive Energy Audit for a distinguished Electrical Equipment Manufacturer based in Kolkata, West Bengal. The client engaged our services to optimize energy consumption, enhance operational efficiency, and align with sustainable practices within their manufacturing facility.
A comprehensive energy audit for an electrical equipment manufacturer in Kolkata, West Bengal identified ₹19.3 lakh in annual energy savings — led by transformer load balancing, cooling load optimisation, and elimination of idle motor running — delivering a project payback of 18 months against an audit and implementation investment of ₹2.9 lakh.
Bureau of Energy Efficiency (BEE) benchmark data for electrical equipment manufacturing shows specific energy consumption of 120–180 kWh per tonne of finished product, with transformer winding shops, paint curing ovens, and compressed air systems consistently identified as the top three energy waste points. WBSEDCL (West Bengal State Electricity Distribution Company) HT tariff structure (applicable above 11 kV connections) includes demand charges of ₹350–420 per kVA per month — charges that an energy audit can reduce by 15–25% through demand-side management and tariff rationalisation.
A Kolkata manufacturer of distribution transformers and switchgear panels with 22,000 sq.ft of production area was operating two 630 kVA main transformers at 34% and 72% loading respectively (ideal loading: 60–70% each), maintaining 0.84 power factor (WBSEDCL surcharge zone), running 18 motors continuously without load scheduling, and using T8 fluorescent lighting throughout the facility. The audit identified opportunity to consolidate to one 630 kVA and one 400 kVA transformer (saving ₹1.8L/year in no-load losses), power factor correction to 0.98 (saving ₹2.7L/year), load scheduling programme (₹4.2L/year), and LED retrofit (₹1.9L/year).
The manufacturer’s products — distribution transformers and switchgear — are tested under IS 1180 and IS 13947 respectively, requiring precise laboratory environments; the energy audit integrated production scheduling flexibility constraints to ensure recommended demand-side management did not compromise test cell environmental controls.
“WBSEDCL’s HT tariff order (2024) imposes a power factor surcharge of 1.5% per 0.01 unit below 0.90, meaning a plant with 0.84 PF on a ₹30L annual bill pays ₹2.7L in unnecessary surcharges — fully recoverable by a ₹1.2L capacitor bank installation.”
