Astana-3 power station (also referenced as Astana CHP-3, Akmola CHP-3, ТЭЦ-3 Астаны, ТЭЦ-3 АО"АлЭС", Астанинская ТЭЦ-3, or TETS-3 AO "Ales") is a 240-megawatt (MW) natural gas- and coal-fired combined heat and power station under construction in Astana, Akmola region, Kazakhstan.


The map below shows the exact location of the power station in Astana, Saryarka district, Akmola region, Kazakhstan.

The proposed power station is near the Astana-1 power station and Astana-2 power station. Construction has been underway at the site for more than 10 years, originally as a coal plant (subsequently cancelled). Since at least 2018, the project has been changed to a gas-fired power station, with coal as a back-up fuel.


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 Ekibastuz, Kazakhstan.[1]

Construction & repeated delays

The website for a heat and power engineering institute named АО «Институт «КазНИПИЭнергопром» listed the construction of CHP-3 in Astana's 1st stage as a project with a timeframe of 2010 to 2015.[2]

In July 2012, a Forbes article discussing how corruption interferes with cleaning the air of Kazakhstan from hazardous emissions from thermal power plants also noted that Astana CHP-3 (Астанинская ТЭЦ-3) was under construction. In addition, only basic "dust cleaning" was set to be installed at the site.[3] The power station was scheduled to be completed by 2016.[4]

A 2010-2014 government table forecasting power projects in the Northern, Western, and Southern zones from 2014 through 2030 listed "CHPP-3 Astana 240 MW" as 120 MW expected in 2018 and 120 MW expected in 2019.[5]

However, in 2018, a Deputy Chairman at a press conference of the municipal holding JSC Astana Energo Service (AES) noted that "construction readiness" was somewhere around 93 percent and "technological equipment readiness" only around 50-60 percent, for a "total readiness" of 62.3 percent. The power station's launch was expected by "next year" (or 2019).[4]

In February 2021, a local government agency reported that construction and installation work was stalled and planned to resume in the third quarter of 2021, with completion before the start of the heating season in 2022/23. The project appeared to be 70% completed.[6] In November 2021, the Mayor of Astana stated that construction has resumed.[7]

Financial controversies

The project has been underway for more than a decade, and although the initial project was estimated to cost 87 billion or 193.7 billion tenge (US$203-451 million), many believe that the project updates and delays are resulting in significant cost increases.[8][9] In addition, many are concerned by the general lack of transparency over the years, and the project contractor, АО «Центрказэнергомонтаж», has been criticized.[8]

In 2014, there were rumors that Russian entrepreneurs would become the investors of the second stage of Astana CHP-3 by agreement with the Central Asian Fuel and Energy Company (CAPEC).[9]


Astana Energo Service (AES) is the power and heat holding in Astana. The companies that are part of the AES holding include Astana Energia (power and heat generation). Astana Energosbyt, a private entity totally independent from AES, is the power and heat billing company responsible for commercial distribution of heat.[10]

Project updated from coal to gas

In 2018, Astana Energo Service proposed completely transferring Astana CHP-1 and CHP-3 from coal to gas.[4]

According to an October 2020 audit by the Accounts Committee for Control over the Execution of the Republican Budget publicized in July 2021, the construction of Astana CHP-3 has been frozen since 2018 to "adjust the design and estimate documentation." 5 billion tenge (US$12 million) was allocated from the Republican Budget for the project, and construction work resumed at the site in May 2021.[11] At least an additional 30 billion tenge (US$70 million) is needed to finish the project.[8]

In February 2021, it was reported that the main fuel at the facility would be natural gas, with coal as a backup fuel. In addition, the city may build two additional "local gas boiler houses."[6][9] As reported in January 2022, the Mayor of Astana has instructed the company to complete the construction in 2022.[12] As of November 2022, construction works were reported to be 83% complete, with the start date moved to 2023.[13]
