Aksu power station (哈萨克斯坦阿克苏发电, ГРЭС г.Аксу АО "ЕЭК", Аксуская ГРЭС ЕЭК, Ермаковская ГРЭС (predecessor)) is an operating power station of at least 2510-megawatts (MW) in Aksu, Pavlodar, Kazakhstan with multiple units, some of which are not currently operating. It is also known as Aksuskaya power station.

Project-level coal details

  • Coal source(s): Vostochny Coal Mine

Background

The Aksu power station, formerly known as the Ermakovskaya State District Power Plant (GRES),[3] was initially an 8 x 300 MW coal plant commissioned from 1968 to 1975 in Aksu, Pavlodar, Kazakhstan. It is owned by Eurasian Energy Group, which belongs to Eurasian Resources Group (ERG). Eurasian Energy Group also includes Vostochny coal mine (Kazakhstan).[4]

The units have been undergoing modernization: comprehensive modernization with of at least five out of eight units has already been completed.[5] In 2004, unit 4 was modernized and its capacity increased to 310 MW.[6] In 2006, unit 3 was modernized and its capacity increased to 325 MW.[6][7] Unit 6 was modernized in 2013.[3] From 2015 until 2018, unit 5 was modernized and its capacity increased to 325 MW.[6] Units 2 and 6 capacities were increased to 325 MW, bringing the plant's capacity to 2,450 MW.[5][8]

Electricity generation in 2020 reached 14 billion kWh[9], 15.1 billion kWh in 2021[10] and 14.6 billion in 2022.[11] The power plant was the second largest producer of electricity in Kazakhstan after Ekibastuz-1 power station.[10]

The power station has been described as "a vivid example of the so-called coupled generation": it meets the needs of the largest metallurgical plants of the Eurasian group – Aksu Ferroalloy Plant, Pavlodar Aluminum Plant, and Kazakhstan Electrolysis Plant.[12]

One worker died in the boiler section of the plant in July 2022.[13]

In May 2023 ERG reported that it signed a cooperation agreement with Power China to develop partnership in the generation sector.[14]

Pollution ranking

The government decree from April 2022 ranked Aksu power station as Number 2 in the list of the main polluters in Kazakhstan as of 2021, after Ekibastuz GRES-1. The government decree comes into force from 2025.[15] It was not clear what the purpose of the ranking is.

Proposed expansion

The expansion of the plant was briefly mentioned in a media source from February 2023.[16] Based on a Ministry of Energy document from March 2023 (unavailable online), a 650 MW coal expansion was under consideration at Aksu GRES.

A September 2023 report titled "Kazakhstan Energy Transition: Steppes to Net Zero" by Carbon Tracker Initiative summarized the government plan to develop the expansion as follows: units 9 and 10 (2 x 325 MW). The new coal units would provide more than just power.[17]

Government report from January 2024 confirmed the plan to build a new 325MW unit at the plant, although it was referred to as Unit 7. [18]
