EVNHANOI issues important notice to electricity customers ahead of peak summer demand

As Vietnam’s northern region moves closer to the peak summer period—when electricity demand typically rises sharply—Hanoi Electricity Company (EVNHANOI) has issued a warning urging residents and businesses to save electricity and use it efficiently to reduce pressure on the power system.

Rising summer demand and need for conservation

With forecasts indicating higher electricity consumption during the hot season this year, EVNHANOI called on customers to improve awareness of electricity-saving measures. The company said maintaining rational electricity use can help reduce costs while also limiting the risk of overloading, particularly during peak hours.

EVNHANOI highlighted that conservation should start with small changes in daily habits. It cited practical steps such as turning off devices when not in use, limiting electricity use during peak hours, and proactively scheduling the operation of high-power equipment. The company said consistent implementation of these measures can deliver long-term benefits and support a more sustainable energy future.

Monitoring usage and demand-response measures

EVNHANOI also recommended that customers monitor their electricity consumption through customer-care applications to proactively adjust usage.

For large electricity-consuming customers, the demand-response (DR) program will continue to be implemented to reduce load during peak hours, thereby easing pressure on the grid. EVNHANOI said it will coordinate with businesses and industrial zones to develop production-adjustment plans aligned with operating conditions.

Rooftop solar as a supplementary option

In addition, residents and businesses were encouraged to consider installing rooftop solar to supplement local electricity supply and reduce dependence on the national grid during peak periods.

Heat outlook for 2026 and warming trend

Experts said the heat in 2026 in Vietnam is expected to appear earlier, last longer, and be more intense than the long-term average, with potential for extreme conditions.

Data from the National Center for Hydro-Meteorological Forecasting shows that from the start of winter through February, the North recorded about 13 cold spells, most of which were weak in intensity and short in duration. This contributed to higher average temperatures compared with many previous years.

Statistics for the three main winter months (Dec 2025–Feb 2026) also indicate that average temperatures in many areas were higher than the long-term average by about 0.1–2°C, reflecting a clear warming trend.
