Summer Heat Drives Soaring Electricity Consumption
As temperatures climb, air conditioning usage is surging, placing increased demands on power grids. This summer spike presents both challenges and opportunities for utilities and consumers, with significant implications for energy consumption patterns and costs.
Cooling’s Growing Demand
With the mercury rising, more people are switching on air conditioners. Since the start of the millennium, cooling has seen an average yearly consumption increase of four percent, according to the International Energy Agency (IEA).
Martin Schreier, a CEZ Group spokesman, affirms this trend, expecting continued growth in summer energy use due to rising air conditioning and cooling needs. Although summer consumption rises, it remains lower than winter heating demands.

“The trend is and will be the continuation of the growth of energy consumption in the summer months by a percentage of percent annually, mainly because of the increasing number of air conditioning and cooling,”
—Martin Schreier, CEZ Group spokesman
Recent data shows that air conditioning use in homes and businesses has increased by nearly 20% in the last decade, indicating a growing reliance on these systems for comfort and productivity (U.S. Energy Information Administration, 2024).
Network Capacity and Urban Impact
Distribution networks easily handle increased cooling needs without issues, confirmed by Roman Šperňák, an electricity spokesman. He states that no network overloads or outages have been recorded due to excessive loads.
The rise in electricity use is more notable in cities due to the urban heat island effect. For example, peak weekday consumption in Prague is currently less than 900 MW. Hanzelka noted that the current high temperatures and air conditioning do not drastically affect the network load.
The most significant summer consumption comes from operational and administrative buildings. Schreier added that supermarkets and data centers show the highest consumption by type, while household consumption remains relatively low.
