Electricity Consumption: Sonelgaz Anticipates Summer Peak

Sonelgaz is preparing for a significant increase in electricity demand this summer, anticipating a 3.5% rise in consumption under normal seasonal conditions, with the potential to surge to 7% during exceptional heatwaves. Fatima Zohra Merzougui, Sonelgaz's communication director, explained that this heightened demand is linked to Algeria's strong economic activity and a growing number of industrial, agricultural, and domestic customers. The company's projections are based on recent historical data, including a record peak consumption of 26,628 MW recorded on July 23, 2025.

We count on a progression of consumption of 3.5% in seasonal climatic conditions, which could climb to 7% in the event of exceptional heatwaves.

The nature of electricity consumption has evolved dramatically. While winter heating once dictated peak demand until 2009, changing lifestyles and widespread air conditioning use have shifted this pattern. Merzougui noted that since 2014, the primary peak now occurs during the day, driven by air conditioner usage. Currently, air conditioning alone represents approximately 40% of a household's energy consumption during the summer months. The most critical consumption periods are between 1 PM and 4 PM, followed by a secondary peak in the evening from 8 PM to 10:30 PM.

From 2014 onwards, we moved to a daytime peak related to the use of air conditioners.

To manage this escalating demand, Sonelgaz initiated a broad rationalization campaign on June 18. The objective is not to diminish comfort but to foster more mindful and efficient consumption habits. Merzougui stated that the campaign will extend throughout the year, targeting various societal segments to encourage a change in consumption patterns. "We cannot continue to consume in this manner," she emphasized.

“

What we ask citizens is just to set the air conditioner to an ambient temperature between 24 and 25 degrees.

Sonelgaz highlights that controlling the energy bill involves simple yet crucial actions. Efficiency begins with purchasing decisions, recommending appliances with energy labels A or B. Proper installation in well-ventilated areas is also advised. Merzougui urged citizens to set air conditioners between 24 and 25 degrees Celsius, explaining that setting them lower during hot weather is unnecessary and leads to significant overconsumption as the unit works harder without reaching the target temperature, impacting family budgets. The company also advises against the simultaneous use of multiple high-consumption appliances.

“

We intend to spread the campaign throughout the year to reach different segments of society and to contribute to a change in consumption habits, because we cannot continue to consume in this manner.
