Ladies & gentlemen, our beloved power supplier, Tenaga Nasional Berhad (TNB) will be doing a major maintenance to its power distribution system in July till early August, for almost the whole of Peninsular Malaysia. But somehow, they did not feel the need to inform millions of their customers except for this brief news article on NST:
It is advisable to be prepared as some areas might experience power interruption as long as 6 hours, and some even up to 11 hours. For residential areas, the power cut will mostly occur in the morning, while for commercial area it will be done after working hours.
You can check the schedule and see if/when your area will be affected here:
Stay safe and stay entertained people!
