Vietnam Electricity Group convened its mid-year review conference on July 6, directing units to secure fuel supplies and prepare hydropower reservoir operations for the 2027 dry season after the national grid recorded a new peak demand of 57,537 MW on June 24. The move comes as EVN’s southern distribution arm confirmed a multi-day scheduled power cut in Tay Ninh province from July 7 to 12, underscoring continued strain on local networks even as system-wide output posted double-digit growth.
Key Facts At A Glance
- EVN held its first-half 2026 review conference on July 6, 2026, chaired by EVN Chairman Dang Hoang An and CEO Nguyen Anh Tuan
- National system output and imports reached 171.54 billion kWh in H1 2026, up 9.85% year-on-year
- June 2026 output alone totaled 32.6 billion kWh, up 14.25% year-on-year
- A record daily output of 1,215.4 million kWh was set on June 25, with peak capacity of 57,537 MW recorded on June 24
- EVN started 89 grid construction projects and energized 94 to 95 transmission works between 110kV and 500kV in H1
- The Quang Trach I thermal plant reached roughly 99% overall progress, with its first unit already connected to the grid
- EVNSPC scheduled outages across residential and commercial areas of Tay Ninh province from July 7 to 12
- NSMO projects full-year 2026 system output at 358.6 billion kWh, an 11.1% increase over 2025
Mid-Year Review Sets Tone For Second Half
Vietnam Electricity Group, the state utility known as EVN, held its first-half production review conference on July 6, reporting that combined system output and imports reached 171.54 billion kWh over the period, a 9.85% increase from the same span in 2025. June alone contributed 32.6 billion kWh, up 14.25% year-on-year, as sustained heat drove demand higher across the country. During a heatwave spanning June 22 to 25, the national grid set fresh records, with daily output peaking at 1,215.4 million kWh on June 25 and maximum capacity reaching 57,537 MW the day before. Northern Vietnam separately posted its highest-ever recorded peak load and output during the same stretch.
EVN Chairman Dang Hoang An and General Director Nguyen Anh Tuan co-chaired the conference, where Pham Quynh, deputy general director of the National Power System and Market Operator, credited close coordination between EVN and the operator for keeping the grid stable through the extreme heat. Quynh also flagged a forecast El Nino pattern expected to affect the system from September 2026 through April 2027, alongside continued load growth, and asked EVN to secure adequate generation fuel, maintain unit availability, and prepare flexible hydropower reservoir operations ahead of the next dry season.
Coal Supply And Grid Investment In Focus
General Director Nguyen Anh Tuan instructed relevant units to work urgently with coal suppliers to review import coal standards and build a fuel supply plan capable of meeting operating requirements for the rest of 2026 and the 2027 dry season. Coal-fired generation remained the dominant source in the first half, supplying 93.44 billion kWh, or 54.5% of total system output.
On the infrastructure side, EVN disbursed 47,561 billion Vietnamese dong of a planned 55,050 billion dong in first-half investment, and started 89 new construction projects while energizing 94 to 95 grid works spanning 110kV to 500kV, including two 500kV and twelve 220kV projects. The Quang Trach I thermal power project reached roughly 99% overall progress, with its first generating unit already connected to the grid and the second unit expected to begin boiler firing in July ahead of a targeted commercial operation date later in 2026.
Reliability indicators also improved. EVN reported that its System Average Interruption Duration Index improved compared with the same period last year, while transmission and distribution losses came in below planned targets.
Local Outages Continue Despite System Gains
Even as national-level output posted strong growth, distribution-level supply interruptions persisted in parts of the country. EVN’s Southern Power Corporation confirmed a scheduled power cut affecting residential areas and businesses in Tay Ninh province, in the area formerly administered as Long An, running from July 7 to 12. Publicly available reporting on the outage schedule did not specify the underlying cause or the number of customers affected.
Looking to the second half of 2026, the system operator projects national output and imports will reach 187.5 billion kWh, a 12.3% increase over the same period in 2025, bringing full-year output to a projected 358.6 billion kWh, up 11.1% from 2025.
