Overview
Vietnam’s national power system operator (NSMO) has issued a warning about severe power supply strain due to extreme heat, with record demand and potential reliance on costly LNG and oil-fired generation. The situation underscores energy security risks and could impact GAS (PV Gas) as a key LNG supplier.
Key Facts
- On May 15, 2026, national peak load reached a record 54,654 MW, up 8.6% year-on-year.
- Power output on May 15 hit 1.152 billion kWh, up 9.9% year-on-year.
- NSMO forecasts northern system load at ~29,000 MW for the week of May 23-27, 9.8% above the May 15 record.
- Hanoi temperatures may reach 40°C on May 25-26.
- NSMO proposes new peak/off-peak hours (17:30-22:30) starting June 2026 to shift demand.
- NSMO plans to mobilize LNG and oil-fired units (e.g., O Mon, Thu Duc, Can Tho) to meet demand.
- NSMO has notified PV Gas (GAS) of LNG mobilization needs.
What Happened
According to a statement from the National Power System and Electricity Market Operation Company (NSMO), widespread intense heatwaves have driven electricity consumption to record levels, placing significant pressure on grid operations. On May 15, 2026, national peak load reached 54,654 MW, an 8.6% increase from the same period in 2025, while total consumption hit 1.152 billion kWh, up 9.9%.
NSMO warned that the peak load is shifting to evening hours (20:00-23:00), when solar power is unavailable and many small hydropower plants lack water. The system also faces risks from reduced coal-fired capacity due to prolonged high operation and potential fuel supply disruptions (LNG, oil, imported coal) from geopolitical instability. To address the upcoming heatwave from May 23-27, NSMO plans to mobilize LNG and oil-fired units, including O Mon (using FO) and Thu Duc/Can Tho gas turbines (using DO). NSMO has coordinated with PV Gas (GAS) for LNG supply and notified power generators to prepare fuel.
Market Context
GAS closed at VND 84,900 on May 22, 2026, down 2.75% on volume of 1.64 million shares. The stock trades on HOSE. The power supply strain and potential LNG mobilization could support GAS’s near-term revenue, but the broader energy sector faces margin pressure from high-cost fuel imports. The warning comes amid Vietnam’s ongoing energy transition and concerns about grid reliability.
Strategic Significance
For GAS, the NSMO warning highlights its critical role as the primary LNG supplier for power generation. Increased LNG mobilization during peak demand periods could boost GAS’s sales volumes and revenue, but also exposes the company to volatile global LNG prices and import costs. The proposal to adjust peak/off-peak hours may shift demand patterns, potentially affecting long-term gas procurement contracts. The situation underscores Vietnam’s need for diversified energy sources and grid investments, which could influence policy support for gas-to-power projects.
What to Watch
- Actual LNG and oil mobilization volumes during the May 23-27 heatwave.
- GAS’s Q2 2026 earnings report for LNG sales and margin impact.
- NSMO’s final decision on new peak/off-peak hours and implementation timeline.
- Any government announcements on energy security measures or fuel import policies.
- Updates on coal-fired plant availability and hydropower reservoir levels.
