PUTRAJAYA: The Energy Commission is unsatisfied with Tenaga Nasional Berhad's (TNB) response over complaints from consumers who say they have been slapped with higher-than-normal electricity bills.

Energy, Science, Technology, Environment and Climate Change Minister Yeo Bee Yin said the meeting was held on Tuesday (May 28) morning.

She said that TNB's explanation was that the issue was due to technical error, among others.

"Although TNB acknowledged this, it must be accountable for it. They must resolve the matter with consumers. If they fail to do so, they will face legal action," she said at a press conference here on Tuesday (May 28).

Consumers have reportedly been slapped with electricity bills much higher than before, with many venting their grievances on social media.

For the month of May alone, more than 300 complaints were lodged with the Energy Commission, which is 10 times more than the same month last year.

Yeo said the complaints were from consumers nationwide and not just those in Melaka, who were part of TNB's smart meter pilot project.

Yeo said the Commission would do its part by investigating the complaints and report the outcome later.

On the smart meter issue, she said the Commission was also investigating what had gone wrong.
