Electricity consumers face potential supply disruptions if Hong Kong imports power from mainland China, Canning Fok, chairman of Power Assets Holdings Ltd. (00006.HK), said Thursday.
Power Assets owns HK Electric Investments Ltd. (02638.HK) which operates power plants that supply electricity to Hong Kong Island and Lamma Island.
Fok said Hong Kong Electric has a reliability rating of 99.9998 percent compared with 99.96 percent for mainland power.
That means Hong Kong could experience 3.2 hours of blackout each year, or 16 minutes per month, he said.
“That would be a major backslash in power supply reliability.”
Fok was reacting to a government proposal to import one-third of Hong Kong’s electricity needs from the mainland.
He said the cost of installing grid infrastructure for imported power would be about HK$20 billion to HK$30 billion.
Also, Hong Kong would lose pricing power and any decision to buy electricity from the mainland is not environmentally sound given that most Chinese power plants are coal-fired, he said.
The government is considering importing 15 billion kilowatt-hours annually from Southern China Power Grid from 2023, media reports said.
