20:39, 06/07/2025

At 11:20 AM on July 6, 2025, at the construction site of the Hoa Binh Hydropower Plant Expansion (Hoa Binh Ward, Phu Tho Province), Vietnam Electricity (EVN) and Power Project Management Board No.1 (PMB1), in coordination with contractors, successfully installed the rotor of Unit No. 1 of Hoa Binh Hydropower Plant Expansion Project. This marks a critical milestone in the equipment installation and unit completion process.

Overseeing the on-site rotor installation process, on behalf of EVN’s leadership were: Mr. Dang Hoang An - Chairman of the EVN Board of Directors; Mr. Nguyen Anh Tuan - Member of the EVN Board of Directors, and EVN President and CEO; Mr. Nguyen Huu Tuan - Standing Deputy Secretary of the EVN Party Committee; Mr. Dang Huy Cuong - Member of the EVN Board of Directors; Mr. Cao Quang Quynh - Member of the EVN Board of Directors; Mr. Vo Hong Linh - Member of the EVN Board of Directors; Mr. Do Duc Hung - Chairman of the EVN Trade Union; Mr. Pham Hong Phuong - EVN Vice President, along with representatives from various EVN departments, Mr. Bui Phuong Nam - PMB1 Director, PMB1 staff, and numerous engineers, technicians, and workers from the on-site construction and installation units.

The rotor of Unit No. 1 of the Hoa Binh Hydropower Plant Expansion Project weighs approximately 585 tons and is the rotating component of the generator. The successful placement of the rotor into the unit's stator must meet strict technical requirements with a high level of precision. The rotor installation is a pivotal step in the sequence of turbine-generator assembly procedures, requiring synchronized and precise coordination among construction, supervision, and electromechanical installation units. The success of this component underscores the determination and concerted efforts of EVN, PMB1, and the contractors, despite the challenging and complex working conditions.

Completing the rotor installation for Unit No. 1 of Hoa Binh Hydropower Plant Expansion Project is of great significance, laying the groundwork for subsequent electromechanical installations, testing, and commissioning to generate electricity from Unit No. 1 by the occasion of the 80th anniversary of the August Revolution (August 19, 1945 - August 19, 2025) and National Day (September 2), in line with the progress targets set forth by the Prime Minister.

Overview of Hoa Binh Hydropower Plant Expansion Project

The Hoa Binh Hydropower Plant Expansion Project is classified as a nationally significant project, approved by the Prime Minister under Decision No. 389/QD-TTg dated April 10, 2018. EVN is the project owner, with PPMB1 serving as the authorized representative.

Project scale: Expansion of the Hoa Binh hydropower plant with 2 generating units, total installed capacity of 480MW (2 x 240MW).
Annual average electricity output: Approximately 490 million kWh.
Total investment: Over VND 9,220 billion.
Construction location: Main works are positioned on the right bank of the existing Hoa Binh Hydropower Dam. The plant is located in Phuong Lam Ward, with the intake and approach canal in Thai Binh, Phuong Lam, and Thai Thinh Wards, Hoa Binh City, Hoa Bình Province (currently Hoa Binh Ward, Phu Tho Province).
Construction contractors: Consortium of Truong Son Construction Corporation - Construction JSC No. 47 - Lilama 10 JSC.

The project is implemented with the following objectives:

Enhance peak load coverage for the national power system and improve the economic operation of the existing Hoa Binh Hydropower Plant within the system.
Enhance the frequency regulation capability and frequency stability of the national power system, contributing to reduced operating costs of the national power system.
Reduce the operational intensity of existing generating units, thereby extending equipment lifespan and lowering maintenance and repair costs.
