Chairman of EVN Trade Union Mr. Do Duc Hung launched the emulation movement in 2024
|
The project has completed all the emulation goals of "Construction and installation of the Ialy Extension Hydropower Plant project" in 2023 according to Joint Directive No. 689/CTLT-EVN-CDĐVN dated February 16, 2023 of the General Director of EVN and the Standing Committee of EVN Trade Union. Such items as intake; headrace tunnel; penstock, main powerhouse, etc., all met and exceeded the emulation schedule milestones. In addition to the goals according to the emulation commitment, Power Project Management Board 2 has coordinated with relevant contractors to organize the implementation of a number of bidding packages and other work to meet the general project schedule.
The goal is to put the powerhouse into operation in 2024
On behalf of the leaders of Vietnam Electricity, EVN General Director Nguyen Anh Tuan praised the enthusiastic working spirit and efforts of the collectives and individuals participating in the project construction who have overcome many difficulties, and challenges with lots of initiatives and solutions to complete the set goals and tasks.
EVN leaders also sent their deep thanks to the leaders of the units, all officers and workers on the construction site, to the leaders of the authorities and local people of Gia Lai and Kon Tum provinces for the good results achieved by the project.

With the goal of creating a vibrant competitive atmosphere and striving to successfully complete the task, EVN, EVN Trade Union, and Power Project Management Board 2 coordinated with the contractor consortium to launch emulation movement "Generating two units of the Ialy Extension Hydropower Plant in 2024". According to Mr. Do Duc Hung - Chairman of EVN Trade Union, the emulation movement will be implemented from January 19, 2024 to December 31, 2024, with the main emulation categories including Headrace channel and intake; underground items; powerhouse and connection system.
General Director of EVN and Chairman of EVN Trade Union call on contractors, consulting units, organizations and all EVN employees to unite together, raise their sense of responsibility, and the will to overcome difficulties, emulating creative labor to achieve high achievements, contributing to successful completion of the set goals, putting the project into use as soon as possible, contributing to ensure the national energy security.
Some main goals of the emulation "Generating two units of the Ialy Extension Hydropower Plant in 2024":
- Completion of the controlling house to install the equipment: March 2023;
- Completion of excavation and reinforcement of the headrace channel to the intake: July 30, 2024;
- Completion of the concrete construction of headrace tunnel structures, penstock, construction niches and adits: October 10, 2024;
- Completion of powerhouse roofing: March 2024:
- Completion of excavation and reinforcement of the tailrace channel: July 30, 2024;
- Completion of expanded construction of the existing switchyard and connected 500kV TL: September 30, 2024;
- Connection, power generation of unit 1: November 20, 2024;
- Connection, power generation of unit 2: December 31, 2024;

PECC1's assignments at the project:
- PECC1 provided the Consulting services with preparation of construction drawing design (excluding project landscape design); designed the hydro-mechanical equipment manufacture; described the geological features of the foundation pit during the project construction process; advised the instrumentation and prepared the report evaluating instrumentation results and project status.
Outstanding PECC1’s achievements at the project:
- 2023 is a pivotal year for the construction of concrete works to serve the installation of hydro-mechanical equipment of the powerhouse in 2024 and serve the power generation target in 2024. With much experience, the Company's engineers have selected, arranged and designed items in accordance with the construction sequence to ensure safety, meet the construction schedule and future operations;
- PECC1 has applied such new design technology as BIM for all phases from the investigation to the design to push up the schedule and restrict the shortcomings which may happen. Accordingly, the geological investigation was 3D modeled with the joint sets, faults sets based on which more appropriate solution will be provided. The design works are simulated according to the model using BIM technology to avoid the conflict may happen during the design process to minimize the repairs works at the site and push up the construction schedule at the site.
- The work of describing the foundation pit is always on site. Together with the author supervisor, the Supervision Consultant provided a solution to reinforce the surface excavated slope as well as nearly 4km underground tunnels and surge tank with an underground compartment with its width of 15.5m, the height of the excavation compartment is 15.6m. The vertical shaft of the surge tank has an outer diameter of 14.0m, the upper chamber on the surge tank has an excavation width of 13.0m, an excavation height of 14.6m and is designed without a lining.
- Ialy Extension HPP is the 3rd project in Vietnam with the most complex underground compartment volume and underground items in Vietnam (after Ialy HPP, Huoi Quang HPP, Hoa Binh HPP). To date, PECC1 is the only consultant in Vietnam to complete the design of an underground hydropower house (already put into operation). Particularly, Hoa Binh underground powerhouse was designed by the Russian consultant.
- With the determination to design the project items of the Ialy Extension HPP, PECC1 has met the design documents to ensure the concrete construction schedule in 2023 to serve the power equipment installation in. 2024 and serving the power generation target in 2024. With the achievements, EVN awarded Certificates of Merit to PECC1 and Mr. Nguyen Huu Chinh – Project Manager of the Project.
