Some key tasks of EVN in last six months of 2026

Following the directives of the Government and the Prime Minister in Resolutions No. 168/NQ-CP and 169/NQ-CP dated 27 June 2026, the target for 2026 is to strive for double-digit growth while maintaining macroeconomic stability.

Power generation and supply:

According to updated calculations by NSMO, total electricity generation and imports for the entire system in the last six months of 2026 could reach 187.5 billion kWh (a 12.3% increase compared to the same period in 2025), and the projected total for 2026 is 358.6 billion kWh, an 11.1% increase compared to 2025. For the Northern region, according to the Center for Hydro-Meteorological Forecasting and annual patterns, prolonged heatwaves may continue, leading to increased load demand peaking in July and August 2026. The projected peak load is expected to reach 30,550–31,550MW, representing an increase of approximately 16.8% compared with the same period in 2025 and 1,500–2,500MW higher than the peak load recorded during the first months of 2026. At the same time, from July 2026, the main flood season will begin in the North and the flood season will start in the Central and Southern regions.

To ensure power supply in all situations and meet growth targets as directed by the Party, Government, and Ministries, EVN requires its member units to continue focusing on implementing solutions and plans to ensure power supply until the end of 2026, preparing contingency plans in case of higher electricity demand growth; while ensuring safety during the rainy and stormy season and actively preparing for the 2027 dry season.
