Astana-2 power station (ТЭЦ-2 АО "Астана-Энергия", ТЭЦ-2 в Нур-Султане) is an operating power station of at least 600-megawatts (MW) in Nur-Sultan, Saryarqa District, Akmola, Kazakhstan. It is also known as Akmola-2 power station.

Project-level coal details

  • Coal source(s): Bogatyr coal mine


Nur-Sultan (formerly known as Astana) is the capital of Kazakhstan located on the banks of the Ishim River in the middle of steppes and has an extreme continental climate with some of the coldest winters in the world. Heating is centralized and the heating season in the city starts in October and is extended until May. As a result of coal burning and still air, the city experiences frequent smog episodes. The power stations utilize coal extracted from the open-pit mine Bogatyr coal mine in Ekibastuz, Kazakhstan.[1]

In September 2022, 100% of shares in Astana-Energy were transferred to the municipality of Astana.[2][3] Previously the company was owned by Astananergoservis JSC.[4] It is understood that Astanaenergoservis was also in municipal ownership.

The power plant has 6 turbine units totalling 600MW, 6 water boilers and 8 energy boilers.[5] The first three turbine units were put into operation in 1979-1983. The Urals Turbine Factory supplied three additional 120MW turbine units that went online in 2006, 2015 and most recently in 2021.[6]

In February 2023, Astana Energy mentioned in a press release that the planned modernization of Unit 1 will lead to capacity increase by 35MW, in addition to building of additional water boilers 7 and 8.[7] The timing was not disclosed.

In February 2024, Unit 4 experienced an outage due to a malfunction in the regulation system, which resulted in a rupture of the compensator. It was reported that defects were corrected and the unit resume operations shortly.[8][9]

Conversion to gas (water boilers)

Astana-Energy has been working on projects to convert Astana-2 power station and the smaller 22MW Astana-1 power station from coal to gas.[10]

However in 2021 it has been clarified that at Astana-2, only the hot water boilers will be converted to gas for district heating purposes, but not the power-generating turbines.[11][12] The conversion project cost was estimated to cost 3.9 billion tenge (US$9 million).[13] In February 2021, it was reported that one hot water boiler is gas-fired[13] and as of July 2021, four hot water boilers transitioned to operate on gas.[12]

In August 2022, it was reported that all 6 water boilers have already transitioned to gas.[14] The remaining 8 energy boilers will continue to run on coal.[15] Given these updates, it was considered that the project to convert the turbine units to gas is cancelled. Gasification is resulting in a significant increase of district heating tariffs in Astana due to higher cost of gas.[13][15]

The conversion of 6 water boilers was confirmed in a later media source from October 2023.[16]

Despite conversion of the water boilers to gas, in the winter season of 2022/2023 there were significant restrictions of gas usage and the station had to rely on coal. Restrictions were in place from December 7th to February 20th and the station could only receive 50 thousand m3 per hour versus the peak requirement of 150 thousand m3 of gas.[17]
