1. PRE-ARRANGE INTERRUPTIONS Electric service is cut off at designated areas for a definite period of time so that repair crews can do maintenance work and upgrade distribution facilities like high-tension wire, poles, transformer, etc. This is necessary to improve service reliabilility in the distribution system.

2.LACK OF POWER SUPPLY Generating stations of the National Power Corporation (NAPOCOR), which supply electricity to the Luzon Grid and other island grids, have to stop occasionally for repairs, adjustments or annual maintenance. When ever the available supply is less than the combined customer demand, the electric cooperative has to resort to rotating service interruptions or brownouts to prevent the remaining units from getting overloaded, a situation that could develop into total system shutdown.

3. MAN-MADE ACCIDENTS Brownouts occur when an electric post and other electric facilities are hit by a motor vehicle or other mechanized equipment, when construction materials fall on power lines, or when kite strings get entangled with power lines. These incidents will cut distribution wires and cause power interruption.

4. FIRES AND FLOODS Fires and floods are emergency situations which make it necessary for the electric cooperative to shut off power temporarily in the affected areas for public safety.

5. THUNDERSTORMS AND TYPHOONS When lightning hits electric wires, transformer or substations,widespread power interruptions will ensue. Thunderstorms and typhoons can cause substantial damage to distributions facilities resulting in extensive and prolonged service interruptions.

6. TREES AND VEGETATION During strong winds, intermittent interruptions are often caused by branches of trees, vines,coconut fronds or bamboo plants momentarily touching bare high-tension wires. At worst, the power lines may burn and fall to the ground.

7. SABOTAGE AND PILFERAGES There are band elements of society who are out to sabotage the country’s economy thru pernicious means. One such practice is sabotage and pilferages of NAPOCOR’s transmission lines particularly those traversing mountain ranges in the countryside. What the saboteurs and pilferers are doing is they damage the transmission towers by blasting, sewing off and stealing the tower parts or causing the whole tower to fall and stealing the aluminum cables. A brownout or black out is triggered once the lines are damaged.

8. Sometimes, short-duration power cuts are caused by (ALD) Automatic load dropping/NAPOCOR’s transmission outages. ALDs occur when a large chunk of power generation is instantaneously removed from the grid causing the system frequency (normally at 60 hertz) to dangerously drop, unless an equivalent amount of power loads are removed from the system.
