HÀ NỘI — Việt Nam Electricity (EVN) on Wednesday announced that it has resumed electricity supply to more than 4.8 million customers out of over 5.9 million customers who have suffered from power outage due to Typhoon Yagi.

According to EVN, the typhoon and its circulation have caused problems to many power lines and distribution transformer stations in northern provinces and cities.

Units under the Northern Power Corporation have been making efforts to promptly fix the problems. By the morning of September 11, a total of 1,376 out of 1,604 medium-voltage power lines with incidents were resumed operation.

Meanwhile, 11 out of 13 incidents that occur on the 500kV high-voltage grid has been fixed; 40 out of 44 incidents on the 220kV grid were repaired; and all ten incidents at 220kV transformer stations were mended.

As many as 158 out of 187 incidents on the 110kV grid were fixed and 94 out of 120 110kV transformer stations resumed operation.

According to EVN, due to the impact of the circulation of Typhoon Yagi, a large amount of water has flown into reservoirs at hydropower plants in the northern region. Hydropower plants are releasing water to regulate water according to the direction of the National Steering Committee for Natural Disaster Prevention and Control and the Steering Committees for Natural Disaster Prevention of provinces and cities.

Specifically, Tuyên Quang hydropower plant is opening five gates to release water, Lai Châu (one gate), Bản Chát (one gate), Huội Quảng (one gate), Thác Bà (three gates), Trung Sơn (six gates), and Bản Vẽ (six gates).

Heavy rains after the typhoon and water discharge from hydropower plants have made water levels in rivers in the North keep increasing in the last few days, posing a high risk of flooding, flash floods and landslides in localities including Lạng Sơn, Cao Bằng, Lào Cai, Yên Bái, Phú Thọ, Bắc Giang, Bắc Kạn, Thái Nguyên and Hoà Bình. — VNS
