Causes of Power Interruption

Causes of Power Interruptions



While ZAMSURECO-I is dedicated to providing efficient,  effective and continuous power delivery service, sometimes, unscheduled power interruptions are inevitable. Knowing what causes these interruptions may help prevent the unnecessary inconvenience of losing electricity. Here are just some of the reasons why these may happen.








Vehicular accidents that topple or break electric posts cause wire down and other damage to electric facilities.

Fires & Floods

During such emergencies, ZAMSURECO-I cuts off power in the affected circuit area until it is safe for residents.

 Trees & Kites

Tree branches that touch bare high-tension wires and kites and strings that get entangled with these wires also cause power interruption. Trim trees before they touch the wires. If branches are beyond normal reach, we will be glad to assist you in trimming them. Call us at 1621.

Illegal Connection

Rampant theft of electricity in an area often overloads electrical facilities. Under Republic Act 7832, electricity or line material pilferage is a serious crime which metes a penalty of up to 20 years of imprisonment. The law also makes the offender liable to pay the value of electricity pilfered plus surcharge.


Falling debris and equipment that touch electric wires in construction work near existing ZAMSURECO-I facilities is another reason. Parties responsible for such outages may be penalized.

Typhoon Winds & Lightning

Electric wires, transformers and substations hit by lightning during  thunderstorms also cause power interruption. Typhoons can cause serious and widespread damage to these distribution facilities.

Maintenance Work

Maintenance and upgrading work on distribution facilities (poles, wires, and transformers) is done regularly. During these times, power  interruption is  scheduled. The schedules are published on before Friday and at the Maintenance Schedule page of this website.
