NATIONAL power company Tenaga Nasional Bhd (TNB) said the recent issue which saw many people complaining of excessive high electricity bills was due to a system glitch which occurred from May 15 to May 20. 

Its CEO Amir Hamzah Azizan said that customers who can indicate that the bills were extraordinarily high by producing their past bills would be recompensed by the company. 

He said that the glitch was the main reason of high electricity bills and, as a consequence, the billing period for the month will be longer than the usual 30-day cycle. 

He added that the glitch had already been resolved. 

Amir Hamzah explained that during the five-day downtime, they could not conduct any billings, which led to some homes being overcharged, as the system lumped some unbilled days together once it became operational again.

Thus, instead of charging as per TNB’s usual 30-day billing cycle, the system extended to more than 30 days for some bills, leading to an overcharge.

At the same time, Amir Hamzah advised TNB customers to lodge a complaint if they have been overcharged at any point in time, including incidents prior to May 15, so that the power company can conduct an investigation. 

“We give our commitment that for every report lodged with us, we will do our best to investigate and give the necessary support,” he said at a press conference at TNB’s headquarters today. 

He said that throughout April and May, the company had received 14,469 reports of unusually high electricity bills and they had already solved 11,331 of the cases. – May 31, 2019.
