Ensuring energy security, improving the quality of power grid operations

NDO - On May 9, Lao Cai Power Company (PC Lao Cai) held a conference to review the operational coordination between PC Lao Cai and hydropower plant investors in Lao Cai province. The conference had representatives from the Northern Power Corporation and 40 hydropower plant investors.

Currently, Lao Cai province has 71 hydropower plants with a total capacity of more than 1,165MW generating electricity on the 110kV and medium voltage grids managed by PC Lao Cai. The total hydropower output to the Lao Cai grid in 2024 will reach more than 3.53 billion kWh, of which the 110kV grid accounts for more than 3.1 billion kWh. In the first 4 months of 2025, the output will reach more than 426 million kWh.

However, the challenge is not small when in 2024, 22 incidents of 110kV power grids under customer management were recorded, an increase of 9 incidents compared to 2023. The main causes were atmospheric overvoltage (accounting for 73%), equipment operating for a long time and deteriorating in quality, and violations of the line corridor.

At the conference, Mr. Nguyen Anh Tuan, Director of PC Lao Cai emphasized the spirit of learning and wished that factories would review and improve the coordination of operations: Equipment maintenance and repair is not only to ensure system safety but also a practical benefit of factories, helping to ensure revenue and income of workers.

Overview of the conference on May 9.

Many key solutions have been proposed, including developing regulations for coordinating management and operations, establishing technical inspection teams, supporting defect handling, sharing materials to fix emergency incidents, and organizing annual summaries to draw experience and improve coordination.

Investors such as Suoi Chan 2 Hydropower Plant and Nam Pang Hydropower Plant expressed high consensus, committed to receiving opinions and improving operations. In particular, the proposal to add lightning protection wires on lines sharing the same poles was unanimously implemented, demonstrating a spirit of responsible cooperation.

Speaking at the conference, Mr. Vu Anh Phuong, Deputy General Director of the Northern Power Corporation, acknowledged and highly appreciated the efforts of PC Lao Cai as well as many investors, and frankly pointed out some limitations in the coordination of operations of some factories. He requested investors to seriously carry out maintenance and repair work, proactively invest in upgrading the power grid to minimize incidents, not only for national energy security but also for the direct benefit of enterprises.
