Astana-2 power station

From Global Energy Monitor

Astana-2 power station (also known as Akmola-2 power station, ТЭЦ-2 АО "Астана-Энергия", and Астанинская ТЭЦ-2) is a 600-megawatt[1] (MW) coal-fired combined heat and power[2] station in Nur-Sultan (formerly Astana), Akmola region, Kazakhstan.[3]

As of 2021 there is a proposal to convert the power station's main fuel to natural gas.

Background

Location

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” in Ekibastuz, Kazakhstan.[4]

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.[1]

Conversion to gas

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.[6]

However, 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.[2][7]The conversion project cost was estimated to cost 3.9 billion tenge (US$9 million).[8] In February 2021, it was reported that one hot water boiler is gas-fired[8] and as of July 2021, four hot water boilers transitioned to operate on gas.[7] In August 2022, it was reported that all 6 water boilers have already transitioned to gas.[9] The remaining 8 energy boilers will continue to run on coal[10] Given these updates, it is 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.[8][10]
