SYSTEM LOSS defined as an energy losses of an electric distribution system that are unaccounted for or the difference in the energy purchased and/or generated and the energy sold.

A. FACTORS OF SYSTEM LOSS

1. Technical Loss

  • Inherent losses from electrical materials such as conductors, connectors and splices.
  • Defective/broken insulators.
  • Equipments such as substation and distribution transformers
  • Power lines (primary and secondary distribution lines)
  • Over extended power line that will cause low voltage
  • Other

2. Non-Technical Loss
(is caused primarily by human errors)

  • Inaccurate meter reading and/or billing
  • Unread KWH meters
  • Unbilled new connections
  • Insufficient Right-Of-Way/Non-clearing of Power Lines
  • KWH meter tampering
  • Defective/In-accurate kwh meters
  • Pilferage (RA 7832)
  • 24-hours service of streetlights (only 12-hours billing)
  • Etc.

3. Administrative Loss

  • Electric energy used by distribution utility in the proper operation of the distribution system and;
  • Unbilled electric energy that is used for community related activities such as:

a. Distribution substation
b. Offices of the DU
c. Warehouse and workshops of the DU
d. Community activities
e. Other essential loads of the DU

B. IMPACT ON HIGH SYSTEM LOSS

  • High Billing Rates
  • Revenue Loss
  • Coop decategorization
  • More customer’s complaints

Note: Please report any illegal connection to avoid system loss

C. SYSTEM LOSS REDUCTION MEASURES

    • Clearing of Lines/Hataw Linis Linya
    • Power system sanity check
    • Rehabilitation and correction of lines
    • Replacement of defective kwh meters and Broken Insulators
    • Checks at hotspots area
    • Strengthen KWH meter reading/billing monitoring system
    • Massive Inspection – Sugpo Electricity Pilferage
    • Massive Pole Metering
    • Primary Metering of Big Load Connections
    • Kislap Koryente
    • Massive Disconnection of Illegal Street Light Connections
