Customer Service:

After the Ministry of Industry and Trade issued Decision No. 963/QD-BCT on changing the peak, off-peak and normal hours of the national power system expected to be applied in the dry season of 2026, to optimize the system, especially during peak hot weather periods, EVN directed the Power Corporations and Power Companies to: (1) Organize propaganda, dissemination and widely inform electricity users, especially those using electricity based on the time of day (three-price system) to plan electricity use proactively. (2) Proactively train personnel, and at the same time prepare materials and equipment to serve the work of updating and resetting meters for electricity users to promptly implement the requirements set out in Decision No. 963/QD-BCT.

Construction investment: In May 2026, EVN continued to direct and urge its units to implement key works, especially those scheduled for Commencement Date/Completion Date in the second quarter of 2026. Specifically, Unit 1 of the Quang Trach I Thermal Power Project successfully completed its first coal firing, while 11 projects were commenced, and 9 power grid projects from 110kV to 500kV were completed and put into operation.  Cumulative results for the first five months of 2026 indicate that 65 projects were commenced and 80 power grid projects were completed and energized, including 2 projects at the 500kV level, 9 at 220kV, and 69 at 110kV.

To ensure power supply for APEC 2027, the Phu Quoc 220kV Substation project and the Phu Quoc – North Phu Quoc and Phu Quoc – South Phu Quoc 110kV transmission line projects are scheduled for completion in September 2026.

BESS installation projects: Hanoi Power Corporation is expected to complete 50MW in July 2026; Northern Power Corporation is expected to complete 305MW in September 2026.

Some key tasks of EVN in June 2026

Forecasts indicate that temperatures will continue to rise in June 2026, with extreme heat waves continuing across all three regions, thus increasing electricity demand. According to the June 2026 national power system operation plan published by the NSMO, total electricity generation and imports across the entire power system are projected to reach around 31.4 billion kWh.

To ensure a reliable power supply in all situations, EVN has instructed its units to continue prioritizing the implementation of measures and plans to secure electricity supply during the peak-demand period of 2026. Specifically:

- Hydropower companies: Regularly monitor and update weather and hydrological conditions, closely coordinate and exchange information with local authorities and relevant state management agencies, and proactively develop plans to ensure the safety of power works during the rainy season and floods. Closely coordinate with NSMO to ensure harmonious and efficient water resource utilization.

- Thermal power companies:

+ Strictly implement directives from the Prime Minister, the Ministry of Industry and Trade, and EVN regarding fuel preparation to ensure electricity production.

+ Strengthen inspection and supervision of equipment and production lines; proactively replace equipment at risk of abnormal failure; absolutely prevent incidents or reductions in capacity due to subjective errors.

+ Prepare well the conditions to ensure safe and stable power production according to the national power system's operating plan; closely coordinate and strictly comply with NSMO's operational dispatching orders.

+ Be ready with plans, personnel, materials, and equipment at the plant to ensure the fastest possible on-site incident response capability and minimize unplanned downtime in the event of an incident.

+ Operate exhaust gas treatment systems (FGD, SCR, ESP...), strictly control emission parameters (exhaust gases, wastewater, ash) to ensure they always remain within the permissible limits as stipulated by law.

+ Proactively coordinate with fuel suppliers (coal, oil, gas) to plan for sufficient fuel for operation and inventory according to established standards. The objective is to ensure an adequate fuel supply to meet current requirements while formulating a plan to secure a stable and reliable long-term fuel supply.

- National Power Transmission Corporation: Ensure the highest possible availability of power lines, equipment, and protective relays, including shunt reactors to support voltage regulation; continue to strengthen the review and effective implementation of solutions to minimize incidents.

- Power Corporations/Companies:

+ Develop specific response plans and work with large electricity consumers to create load shifting/adjustment plans to cope with extreme situations and peak power shortages during the peak dry season.

+ Closely coordinate with the NSMO in managing and forecasting electricity load demand, assessing the impact of the development of distributed power sources (especially self-produced and self-consumed rooftop solar power sources), the development of electric vehicles, promoting electricity saving solutions, efficient energy use, load shifting, and preparing load balancing/regulation plans, mobilizing customer diesel to respond when necessary;

+ Urgently implement investment and installation of battery storage systems (BESS) on the distribution grid to ensure power supply capacity for 2026 and subsequent years, especially in the Northern region;

+ Maintain close coordination with the People's Committees of provinces and cities to promote the strict and effective implementation of electricity-saving programs and solutions by government agencies, public offices, and local authorities, as well as the development of rooftop solar power in line with Directive No. 10/CT-TTg dated March 30, 2026, of the Prime Minister.

Regarding investment in power source construction: Ensure the progress of key power source projects: (i) Quang Trach I Thermal Power Project: commercial operation of unit 1 in August 2026; (ii) Quang Trach II LNG Project: implementation according to the signed contract schedule; (iii) Quang Trach III LNG Project: striving to start construction in the fourth quarter of 2026; Continue focusing on the construction of the Tri An Hydropower Expansion Project and the Bac Ai Pumped Storage Hydropower Project according to the planned schedule for 2026...

Regarding power grid investment and construction:

Expedite the progress of projects targeted for energization in June 2026, such as the Nhon Trach 3 – Long Thanh 220kV transmission line and the Dai Mo 220kV Substation in Hanoi, while accelerating the implementation of BESS installation projects.

To alleviate difficulties in operating the power system during the dry season and prolonged hot weather, and to minimize the risk of power outages due to increased electricity demand – especially in the North – EVN hopes to continue receiving the cooperation and active support of the people and electricity customers through the thorough use of electricity for energy saving, paying attention to avoiding the simultaneous use of many high-power electrical appliances during peak hours. The thorough implementation of electricity-saving measures will help minimize the risk of power outages and curb increases in electricity expenses.
