PRIMARY — KSERC Order No. 427/D(T)/2023/KSERC dated 05.12.2024 (Kerala Gazette Extraordinary Vol.XIII No.3939, 09.12.2024), rates column 'w.e.f 01.04.2025 to 31.03.2027'. Category LT-VII Commercial (A) — shops, hotels, lodges, cold storages etc. IMPORTANT: KSEB bills this NON-TELESCOPIC (the entire month's consumption is charged at the single rate for the slab it falls in, not incrementally block-by-block) — same limitation already flagged for this file's residential LT-I telescopic-only modelling above 250 units. Using these slab boundaries telescopically will understate bills for consumption above 100 units/month. Monthly billing cycle also mismatches this file's declared bimonthly cycle (rates shown are per KSEB's native monthly basis, not doubled).

Detailed Charges
PRIMARY — KSERC Order No. 427/D(T)/2023/KSERC dated 05.12.2024, same source as commercial, rates w.e.f 01.04.2025. Category LT-IV(A) Industry, connected-load-below-10kW tier (Rs.140/month flat + Rs.5.90/unit). For connected load 10-20kW the rate is Rs.5.95/unit with Rs.95/kW/month fixed charge, and above 20kW it is Rs.6.00/unit with Rs.215/kVA/month — neither higher tier is modelled here. A 20% surcharge applies if capacitors are not installed (not modelled).
