China National Nuclear Corporation (CNNC), which previously secured the contract for Kazakhstan’s second nuclear power plant, will now lead the construction of a third facility, according to First Deputy Prime Minister Roman Sklyar.
In October 2024, Kazakh citizens voted in a national referendum in favor of nuclear energy development. Following the vote, President Kassym-Jomart Tokayev announced the need to construct at least two, and ideally three, nuclear power plants. In June 2025, Russia’s Rosatom was selected to build the first plant near the village of Ulken, on the western shore of Lake Balkhash, approximately 400 kilometers northwest of Almaty.
Simultaneously, CNNC was announced as the builder for the second facility. Potential locations for this project include Kurchatov, near the former Semipalatinsk nuclear test site in eastern Kazakhstan, and Aktau, the former site of the Soviet-era BN-350 fast neutron reactor in the west. The identity of the third project’s contractor remained unclear until now. Alongside Rosatom and CNNC, South Korea’s KHNP and France’s EDF had been shortlisted.
“The third nuclear power plant will also be built by China,” Sklyar confirmed during a press briefing. When asked whether this referred to CNNC specifically, he replied in the affirmative.
Kazakhstan’s Atomic Energy Agency and Kazakhstan Atomic Power Plants LLP are currently evaluating potential sites for the second and third nuclear plants. “Work is underway, and I believe the locations will be announced later this year,” Sklyar said. “Each plant requires a permanent source of water and electricity, and the exact districts must be carefully selected.”
Meanwhile, negotiations on the intergovernmental agreement for the first nuclear plant, being developed by Rosatom, are ongoing with Russian officials. “Once finalized, the agreement will be submitted to parliament for ratification,” Sklyar added.
The first nuclear power plant is planned to have two units with a combined capacity of 2.4 gigawatts and is expected to be operational by 2035. The project is intended to help offset Kazakhstan’s growing electricity deficit, which reached 5.7 billion kWh in January 2025, up from 2.4 billion kWh a year earlier.
To meet its current energy needs, Kazakhstan imports electricity primarily from Russia and recently signed an agreement with Tajikistan to purchase additional power from the Rogun Hydroelectric Power Plant.
