The 230-kilovolt Shwegyin-Thayagon power transmission line, which was damaged in an attack in September 2023, has been restored, allowing electricity from the Shwegyin Hydropower Plant to reconnect to Myanmar’s national grid. The line sustained severe damage on September 26, 2023, resulting in the collapse of 11 transmission towers in Nyaunglebin Township. This disruption halted the transmission of the hydropower plant’s 75-megawatt output, leading to scheduled power cuts in Yangon, Ayeyawady, and other regions.

Following the incident, approximately 300 workers from the Ministry of Electricity and Energy, supported by local residents and operating under the protection of security personnel, undertook the repairs. By August 30, 2026, the damaged infrastructure had been restored and reconnected, enabling an electricity supply of about 80 megawatts—equivalent to roughly 3.2 million units of electricity daily—to be fed back into the national grid. This restored capacity is sufficient to deliver power to nearly 3.5 million people each day.

Since September 9, Yangon has benefited from a continuous 24-hour electricity supply, except during occasional line faults, eliminating the previous requirement for an eight-hour daily load-shedding schedule. The Ministry of Electricity and Energy continues to work on repairing other affected transmission lines and aims to reinforce the national power grid, coordinating efforts with security forces and local communities to enhance overall stability.
