KESCO pre-use inspection fee calculator

Budget for the Korean private receiving-installation inspection that applies to your confirmed classification. The official 2026 table separates base fees, capacity fees and extra line items; the calculator also handles the distribution multiplier and customer-requested night/holiday surcharge. Ordinary pre-use checking is a different service and has no inspection fee.

MAKE IT SIMPLE

KESCO · 2026 private receiving-installation construction inspection table. Inspection and pre-use checking are different services; choose your confirmed classification.

Inspection / checking class

Confirmed inspection capacity (whole kW)Include premises distribution inspection (double capacity fee)Customer-requested night / public holiday / Saturday (+30%)

Additional receiving-installation line items

Wood / steel / concrete poles (total count)Steel towers (total count)Underground cable circuits (total count)

Capacity charge caps at 200,000 kW. For high voltage at 1,000+ kW, capacity rates accumulate: first 1,000 × 268, next 99,000 × 152, remaining × 32. Extra pole/tower/circuit charges do not receive the 30% timing surcharge. VAT 10% is separate; VAT/surcharge round to whole won for this estimate.

Receiving-installation construction only. Reinspection, partial/simultaneous inspections, equipment-only changes, generation/PV/ESS installations and special discounts need a separate calculation. Low-voltage status and inspection eligibility are not determined by this calculator.

How to use

Choose confirmed low/high-voltage receiving-installation construction inspection, or ordinary pre-use checking with no fee. This does not decide legal inspection eligibility.
Enter whole-kW inspection capacity. High-voltage capacity bands are ≤300, >300 and <1,000, then ≥1,000. At ≥1,000 the capacity fee accumulates 268 per first 1,000, 152 per next 99,000 and 32 per remaining kW, capped at 200,000 kW.
Premises distribution doubles the capacity component. Additional poles above 5 cost 10,300 each; towers above 1 cost 45,400; underground circuits above 1 cost 50,500. Enter total counts, not excess counts.
Customer-requested night/holiday/Saturday adds 30% to base plus capacity fee, excluding extra line items. Add 10% VAT and round surcharge/VAT to whole won for the estimate. Partial/simultaneous inspections, reinspections, equipment changes and generation/PV/ESS are outside this tool.

Worked examples

Low-voltage inspection; 100 kW; no extras, distribution or timing surcharge

KRW 133,100 + VAT 13,310 = 146,410

Base 94,000 plus 100 × 391 = 133,100 before VAT.
