Opinion: Kazakhstan Energy Expansion May Not Guarantee a Lasting Surplus
Kazakhstan plans to commission 13.3 GW of power capacity by the end of 2029, including 12.56 GW of entirely new generation, in a build-out the government says will move the country from deficit to sustained surplus. But new industrial projects and large data centers could absorb part of that margin almost as soon as it appears. According to Energy Ministry projections, Kazakhstan expects to eliminate its electricity deficit by the end of the first quarter of 2027 and move to a sustained surplus by 2029. The projected electricity balance for 2029 calls for generation of 162.1 billion kWh against consumption of 144.5 billion kWh, leaving a surplus of 17.6 billion kWh. However, it is difficult to predict exactly how much electricity the country will need three years from now. Therefore the forecast "surplus" will not necessarily become a reserve available for future industrial projects. Energy Hungry Data Centers Kazakhstan is pursuing a swathe of new energy-intensive industrial projects, while data centers are emerging as another major source of electricity demand. The Data Center Valley project is being developed in Ekibastuz, where the government says 300 MW of power capacity has already been secured, with plans to expand to 1 GW. It cites competitive electricity costs and the ability to scale up as advantages of the location. At full scale, such a cluster would itself become a major electricity consumer. If it drew 1 GW continuously, it would consume about 8.76 billion kWh a year – roughly half the projected national surplus for 2029. Kazakhstan’s digital ambitions already extend beyond a single data center. In June, the government announced $10 billion in agreements with U.S.-based Firebird and NVIDIA to build a large AI computing center using 100,000 advanced computer chips. The project will form part of the Data Center Valley initiative. By the end of 2029, Kazakhstan plans to commission 13.3 GW of capacity, of which 12.56 GW will come from entirely new generating facilities and 0.74 GW will replace existing capacity. According to the Energy Ministry, 7.4 GW of the total will be baseload generation and another 5.9 GW will come from renewable energy sources. The full 13.3 GW cannot be treated as spare power for new factories and data centers. Some will be needed to meet rising demand and make the electricity system more reliable. Solar and wind power also cannot produce at full capacity all the time. This is particularly important during periods of peak demand, when the power system must cope simultaneously with high consumption and possible maintenance or outages at generating facilities. A projected annual surplus measured in billions of kilowatt-hours and the amount of capacity available during a particular peak hour are therefore different measures. Upkeep of Current Power Sources The condition of existing generation remains a separate problem. Much of Kazakhstan’s thermal generation is aging and requires modernization. The Energy Ministry reported that 411 billion tenge was allocated to the 2025 repair campaign, during which 10 power units, 63 boilers, and 39 turbines were repaired. It said...
