The Ekibastuz-2 power station (also known as the GRES-2 Power Station or Экибастузская ГРЭС-2) is a coal-fired 1,000-megawatt (MW) thermal power station in Ekibastuz, Kazakhstan. A new 636 MW unit has been proposed.

The Ekibastuz GRES-2 Power Station is a coal-fuelled power generating station in Ekibastuz, Kazakhstan. The station has installed capacity of 1,000 MW, provided by two units of 500 MW each.

Ekibastuz-2 was part a coal-fired complex that included Ekibastuz-1 power station. The construction project was never finished, with only ten of 16 planned power units completed. Only two 500MW units at the Ekibastuz GRES-2 Power Station were commissioned (in 1990 and 1993). After that, construction was suspended.[1]

The plant produced 6433 million kWh in 2021 and 4974 million kWh in 2020.[2]


At the end of 2005 a joint venture between INTER RAO UES JSC and Samruk-Energo JSC was established to operate the GRES-2 Power Station. Its shareholders proposed overhauling existing units and building new ones. In July 2019, Samruk-Kazyna bought Inter ROA's 50% share in the plant.[3] The plant is therefore 50% owned by Samruk-Energy and 50% by Samruk Kazyna. Samruk-Energy is fully owned by Samruk Kazyna.

Expansion & delays

Proposed Unit 3 (500 MW)

Construction of Unit 3 was started in 1990 but later stopped. A 500 MW power unit N3 was then planned to be built in 2008-2009, but also stopped.[4]

In 2010, an agreement to build a third unit at the power plant was reached at a meeting of the Presidents of Kazakhstan and Russia,[5] and the agreement was ratified in January 2011. The project was to be 500 MW at a projected cost of US$770 million. The new capacity was to come online by 2013, with all the additional output to be supplied to Russia. The project cost would be co-funded with a US$700 million loan from Vneshekonombank of Russia and the Eurasian Bank of Kazakhstan.[6]

In January 2014, Russia and China signed an agreement to lend US$400 million for construction of a third electric power generation block at the power station, which matched the deal they first ratified in January 2011.[5]

In March 2014, it was reported that the Inter RAO UES (Inter RAO) and Government of Kazakhstan were planning to undertake the 500 MW power plant expansion, with a project start date of mid-2015 and completion date of 2018.[7] Building and installation works on the unit began that year.[8] However it appears that works did not progress. In April 2018, it was reported that work on the new unit had stalled but resumed in 2018.[9]

Proposed Unit 3 (636 MW)

With the power plant becoming fully owned by Kazakhstan in 2019, Samruk Energy resumed the project with increased capacity of 636MW. In June 2021, reporting noted that construction would not begin until 2023, with the expected commissioning date pushed back to December 2025.[1][10]

In September 2021, Samruk Energy published a press release stating that for the period of 2020 and the first half of 2021, within the framework of the implementation of the project, a wide range of preparatory work had been carried out. Work included financial and technical audits, refinancing of loan obligations before conclusion of contracts for the adjustment of design estimates, and registration of permits for construction. Additionally, more than 11 tonnes of equipment have so far been delivered to the construction site. Construction has not begun, but the project is expected to be commissioned in 2025.[11]

As of December 2021, Inter Rao Engineering is expected to render EPC services for the expansion. Harbin Electric will be the turbine supplier (1 unit of CLN-636-24.2/566/566 steam turbine with 636MW nameplate capacity). Harbin Electric is also the expected supplier of QFSN3-2 electric generator and the likely supplier of steam boiler.[12]

In its 2021 annual report, Samruk-Energy states that an approval of the project by Gosekspertiza (State Technical Supervision Authority) was expected by the end of 2021.[2] However, as of December 2022 there are no news on the approval or progress of the project during 2022.

Environmental impact assessment was published in 2021, and it appears that public consultation took place in June 2021.[13][2]


A loan agreement for Unit 3 was closed in July 2010. US$700 million in loans was provided by Vneshekonombank and the Eurasian Bank of Kazakhstan.[6] In October 2013, a second loan agreement for Unit 3 was closed. The China Development Bank agreed to provide a US$400 million loan.[14]

In 2020, Samruk-Energy reported that all outstanding loans in foreign currencies were refinanced by a loan in tenge from the National Bank of Kazakhstan for a total of over 100 billion tenge (ca USD 210m).[15] Therefore it appears that there is no foreign bank financing anymore.

Pollution ranking

The government decree from April 2022 ranks the Ekibastuz-2 GRES power plant as Number 3 in the list of the main polluters in Kazakhstan as of 2021. The government decree comes into force from 2025.[16] It is not clear what the purpose of the ranking is.
