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]

Gasification

It appears that Astana-Energy has been working on projects to convert its coal-fired combined heat and power stations to gas.[5]

According to February 2021 reporting, the coal units at the Astana-1 central heat and power plant (<30 MW) and the Astana-2 central heat and power plant (360 MW) may switch to gas in the fourth quarter of 2021. [6]

At the Astana-1 power station, three boilers appear connected to gas, and seven more were planned to be translated. The conversion project cost was estimated at 5.6 billion tenge (US$13 million). At the Astana-2 power station, one hot water boiler appears connected to gas, with five planned to be translated, but all turbine units are still functioning on coal.[2] The conversion project cost was estimated at 3.9 billion tenge (US$9 million).[6] It has been stated that at Astana-2, it is possible that only the hot water boilers will be converted to gas, but not the power-generating turbines.[2]

Even after switching to gas, both power stations may still burn coal and fuel oil during severe frosts. The founder of Hairyshev energy, Zhakyp Khayrushev, believes gasification could increase tariffs for heat and electricity by 30%.[6]
