KEGOC Grid Spending May Raise Kazakhstan Power Tariffs

The most immediate project, a 220-kV line linking Taldykorgan, Tekeley, Khorgos and Kokpek, is estimated at 102.2 billion tenge before VAT. KEGOC said 70% of the funding would come from borrowing and 30% from its own resources generated through tariffs. The project is designed to strengthen supply to the Khorgos logistics and industrial hub, unlock more than 600 MW of mini-hydro capacity and improve transmission for future wind and other renewable projects in the Shelek corridor, while also bolstering reliability for Almaty, the country’s largest city.

That matters because Kazakhstan’s power system is being pushed in two directions at once: it must absorb a rapidly growing share of intermittent renewables while also replacing infrastructure built in the 1960s and 1970s that is already showing wear. KEGOC said the second and third phases of its 220-500 kV line rehabilitation program across the north and east could cost 121.5 billion tenge, with 80% of financing also expected to come from debt. The company said the work is meant to help integrate as much as 13 GW of new capacity, much of it variable generation, into a system that must become “strong and flexible” to avoid grid instability.

For investors, the key issue is that the transmission buildout is not optional infrastructure spending; it is the enabling cost of Kazakhstan’s energy transition. The projects support renewable developers, mining and industrial users, and the government’s broader industrial strategy, but they also create a path for tariff pressure as KEGOC recovers borrowing and capex through regulated rates. That raises a familiar trade-off: stronger network reliability and more renewable capacity on one side, higher end-user bills on the other.

A separate 80 billion-tenge project is being prepared to reinforce external power supply to the Karaganda-Temirtau industrial hub, including a new 500-kV substation near Karaganda and new high-voltage lines to Astana and Nura. KEGOC said the investment is intended to protect supply to heavy industry and preserve north-south transmission capacity if power demand rises further from a planned 1 GW complex alloys plant.

The broader pipeline points to a decade-long grid expansion cycle that could reshape Kazakhstan’s power market, with additional projects under study for western-zone integration and a direct current link between west and south. For the market, the story is less about a single line item than the scale of investment required to make the country’s renewables strategy workable — and who ultimately pays for it.
