Kazakhstan’s energy infrastructure is shaped by the size of the country and the uneven location of its resources, industries and population. Large coal-fired power stations are concentrated in the north and northeast, major oil and gas fields lie mainly in the west, and some of the fastest-growing electricity demand is found in the south and around large cities. The result is a set of long-distance networks that must move electricity and fuel between regions separated by hundreds or thousands of kilometres.
The national electricity grid is operated by Kazakhstan Electricity Grid Operating Company, or KEGOC. Its high-voltage network includes approximately 28,000 kilometres of lines operating between 220 kV and 1,150 kV, together with 83 substations. These assets form the backbone of the Unified Power System.
Kazakhstan generated about 123.1 terawatt-hours of electricity in 2025, while consumption reached roughly 124.6 terawatt-hours. The remaining balance was covered through cross-border flows, especially with Russia. This reflects the mismatch between where electricity is generated, where demand is growing and how much power the network can transfer at a given time.
Northern Power Stations Supply a Wider Industrial Economy
Northern Kazakhstan remains the centre of the electricity system. The region contains the Ekibastuz coal basin and major thermal plants, including Ekibastuz GRES-1 and GRES-2. Their output supports mining, metals production, railways, cities and industrial facilities across the country.
The north also serves as the starting point for the main North–South transmission corridors. These lines carry electricity toward Almaty, Shymkent, Turkistan and other southern demand centres. The south has experienced strong population and commercial growth but has less large-scale thermal generation of its own. Hydropower, gas-fired plants, solar farms and imports from neighbouring Central Asian systems help balance supply, yet north-to-south transmission remains essential.
KEGOC is strengthening the southern network and increasing North–South transfer capacity. Current projects are intended to add about 440 MW, reduce congestion and make it easier to connect new generation. Longer-term plans include a direct-current North–South line that could carry power from future nuclear, wind and other large projects.
Western Kazakhstan Is Moving Toward Full Grid Integration
Western Kazakhstan presents a different problem. Atyrau, Mangystau, Aktobe and West Kazakhstan regions contain much of the country’s oil and gas production, but the western power system has historically had limited connection with the rest of the national grid. Local plants, industrial facilities and cross-border links have therefore carried greater responsibility for maintaining supply.
Demand in the west is rising quickly, led by oil production, processing, pumping and associated industry. A weak national connection creates risk because spare generation elsewhere cannot be transferred easily when a local plant or line fails.
The main response is a new 500 kV connection extending more than 600 kilometres. It is designed to integrate the western power system with the Unified Power System and create a more stable national network. A stronger western grid can also support electrification at oil and gas sites, new industrial projects and renewable generation near the Caspian Sea.
Oil Pipelines Carry Kazakhstan to Global Markets
Kazakhstan’s position as a major oil producer depends on pipelines connecting inland fields to refineries, the Caspian Sea, China and international export terminals.
The Caspian Pipeline Consortium route is the dominant outlet for crude from major western fields, especially Tengiz, Kashagan and Karachaganak. It carries oil across Russia to the Black Sea near Novorossiysk. The route provides the scale needed by Kazakhstan’s largest projects, but it also creates concentration risk. Problems affecting pumping stations, maritime loading facilities or transit through Russia can quickly influence national export capacity.
Other routes provide flexibility, although they cannot fully replace the main corridor. The Atyrau–Samara pipeline links Kazakhstan with Russia’s wider system. The Atasu–Alashankou line provides an eastward connection to China. Oil can also move through the Port of Aktau across the Caspian Sea and onward through Azerbaijan toward the Baku–Tbilisi–Ceyhan pipeline.
Kazakhstan has been increasing use of the Trans-Caspian route and working to expand shipments through Azerbaijan. This supports diversification, but marine transport, port handling and additional transfers make it more complex and smaller than the direct CPC system. The practical goal is to create enough alternatives to reduce the economic effect of disruption on any single route.
Gas Infrastructure Serves Domestic Supply and Transit
Kazakhstan’s gas infrastructure moves domestic gas to cities and industries, carries Central Asian gas across the country and connects producers with China and Russia.
Intergas Central Asia manages a trunk pipeline system of more than 14,000 kilometres. Important routes include the Central Asia–Center system, the Central Asia–China corridor and the Beineu–Bozoi–Shymkent pipeline. The last route is particularly important because it links western gas resources with southern Kazakhstan, where demand is high.
Gasification projects are extending access to additional settlements, but long distances, low population density and severe winter conditions raise construction and maintenance costs. In remote areas, the commercial return from a new pipeline may be weaker than the regional-development case for building it.
The network must also balance competing uses. Kazakhstan wants to expand domestic gas consumption, support petrochemical projects, reduce coal use in some cities and maintain export commitments. New processing plants, field gathering systems and storage are therefore as important as the trunk pipelines themselves.
Modernization Must Match New Generation and Demand
Kazakhstan’s next infrastructure cycle will involve more than replacing old lines. KEGOC plans thousands of kilometres of new and reconstructed transmission through 2035, together with digital substations, stronger supply to Astana and additional North–South capacity. These investments are intended to support major additions of thermal, gas, renewable and potentially nuclear generation.
Grid modernization will determine how quickly wind and solar can expand. Kazakhstan has strong wind resources across the steppe and high solar potential in the south, but many projects are far from demand. Transmission, balancing capacity, forecasting systems and flexible generation will be needed to prevent new bottlenecks.
The same principle applies to oil and gas. New production has limited value without export routes, processing plants, compressor stations, storage and port capacity. Kazakhstan already has a large energy network, but its future competitiveness will depend on how well the separate electricity, oil and gas systems are reinforced and connected.
The central challenge is integration. A more unified grid, a broader set of oil export routes and stronger domestic gas connections would give Kazakhstan greater control over how energy reaches consumers and markets. The success of these projects will shape industrial growth, export security and the resilience of the national economy.
