Central Asia Electricity Demand Surges in Summer Power Reckoning
At 5:22 p.m. on July 20, after days of extreme heat, Uzbekistan's electricity system hit its highest load on record. Air conditioners were running on overdrive across the country as demand reached 14.2 gigawatts. Over the full day, consumers used 301.9 million kWh, almost 11% more than the previous year's summer peak. The pressure was visible elsewhere. In Kyrgyzstan, electricity consumption jumped 18% year-on-year on July 19. Parts of Bishkek and the Chui Region lost power for periods of up to two hours as operators tried to stop overloaded equipment from failing. In Almaty, where temperatures reached 40°C, 35 repair crews were deployed as record demand triggered faults across parts of the city's electricity network. Central Asia has spent years preparing for power shortages during freezing winters. July demonstrated that 40°C-plus summer days can now pose a different version of the same problem. The Demand Problem Governments across Central Asia have largely approached energy shortages from the supply side: more generation, new plants, stronger transmission, and greater investment. The summer peak exposed another weakness, however: demand is rising faster than many networks can comfortably absorb it. The pressure comes from new apartment blocks, shopping centers, construction sites, cooling systems, and the rapid spread of air conditioning. In Tashkent, Almaty, Bishkek, and other expanding cities, hotter summers also intensify the urban heat-island effect as concrete and glass retain heat and increase cooling demand. Much of the region's electricity infrastructure was built for a different pattern of consumption. That makes demand-side management increasingly important alongside new generation. Building another plant increases the amount of electricity available, but does little by itself to control when households and businesses consume it. Efficiency standards, more responsive tariffs, modern metering, and investment in distribution networks will become more important as peak demand rises. Four Systems, Shared Pressure Kazakhstan, Uzbekistan, Kyrgyzstan, and Tajikistan are not facing identical problems, but July highlighted a common vulnerability: electricity systems are being asked to meet demand patterns for which they were not originally designed. Kazakhstan is pursuing major long-term additions to generation. In May 2026, it signed a $16.5 billion agreement with Russia's Rosatom for its first nuclear power plant near Lake Balkhash. Construction is expected to begin in 2027, with the first reactor scheduled for commissioning in early 2034. For a coal-heavy system facing rising demand, the baseload argument is clear. But new capacity will take years to arrive. Tariff reform and modernization of existing infrastructure remain politically sensitive, especially if households are asked to pay more before improvements in reliability become visible. Uzbekistan is racing to add capacity, especially solar, in response to a rapidly growing population and dwindling gas reserves. Solar can reduce daytime strain and free gas for other uses, but it does not resolve the evening peak. Cooling demand can remain high after sunset, when solar output falls. Without sufficient storage, flexible backup generation, and stronger transmission and distribution networks, rapid additions of renewable capacity can coexist with local shortages and outages. Uzbekistan's July records underline the...
