HÀ NỘI — Power has been restored to over 6.03 million of Vietnam Electricity (EVN)’s 6.1 million customers affected by Typhoon Yagi and subsequent flooding, equating to nearly 99 per cent.

According to the group’s fresh announcement, 1,640 out of the 1,678 medium-voltage power lines that experienced outages due to the storm had been resumed by the afternoon of September 17.

Overall power restoration efforts in the affected areas are nearly complete. In the northern province of Quảng Ninh, directly hit by the storm on September 7, electricity has been re-supplied for over 85 per cent of the customers.

EVN units in northern Việt Nam are continuing to mobilise personnel, vehicles, and equipment to repair the damage caused by the storm and ensure full power restoration to the remainders as soon as possible.

The Central Power Corporation (EVNCPC) and the Hà Nội Power Corporation (EVNHanoi) have respectively deployed 273 and 200 workers to Quảng Ninh to assist in restoring the power grid.

Due to heavy rainfall following the typhoon, a large volume of water flowed into hydropower reservoirs in the North, prompting the controlled release of water as directed by the National Steering Committee for Natural Disaster Prevention and Control. Water levels in these reservoirs are declining gradually.

Consequently, from 10am on September 17, the hydropower plants of Tuyên Quang, Lai Châu, Bản Chắt, Huổi Quang, Sơn La, and Hòa Bình have closed all spillway gates as instructed by the Ministry of Agriculture and Rural Development, EVN said.

The group noted that the 500kV power grid has fully recovered, with all 14 incidents resolved. The recently inaugurated Circuit-3 500kV line from Quảng Trạch (central Quảng Bình Province) to Phố Nối (northern Hưng Yên Province), which officially went into operation on August 29, suffered no significant damage.

The 220kV power grid has had all 10 transformer station incidents and 38 out of 40 power line incidents fixed. Meanwhile, the 110kV grid has seen 101 out of 104 transformer station failures and 186 out of 190 line outages addressed.

Earlier, Yagi-induced strong winds, heavy rainfall, and flooding across 17 northern provinces caused widespread power outages. In addition to grid damage, severe flooding in certain areas forced the temporary shutdown of operations to ensure electrical safety. — VNS
