Almaty-2 power station

From Global Energy Monitor

Almaty-2 power station (also known as АО "АлЭС" Алматинская ТЭЦ - 2, ТЭЦ-2 имени А. Жакутова, Almaty Heat Electro Central 2, Almaty HEC 2) is a 510-megawatt (MW) coal-fired combined heat and power station in Almaty, Kazakhstan.[1]

There is also a proposal for a new natural gas-fired power station which will replace the existing coal-fired units by 2025.[2]

Background

The Almaty-2 power station is operated by Samruk-Energo JSC and related to the Almaty-1 power station and the Almaty-3 power station.

The 510 MW coal-fired combined heat and power station is the largest thermal power plant in the region and provides Almaty with 60% heat supply and 40% electricity.[3][4]

Proposed conversion to gas

Samruk-Energo JSC is planning to convert the plant's coal units to gas units.[5][6]

In 2021, the company noted the power station would be able to operate for another 10 to 15 years and proposed installing emission controls at the power station to reduce emissions. In addition, the company proposed to finalize a feasibility study to convert the power station to gas.[7]

Original proposal (cancelled)

After considering four separate options, estimated to cost between 100 and 560 billion tenge (US$0.3 to 1.3 billion),[8] a feasibility study was reviewed by the state expertise (RSE, or РГП «Госэспертиза»). In April 2021, the company received a negative conclusion on the proposed study, in part because of the boiler locations.[7] As of May 2021, the company was revising the feasibility study to address comments from the state expertise.[9] According to planning documents, it appears the company must develop a feasibility study for the project and make a decision on the implementation of projects to reduce emissions, in coordination with authorized bodies, by December 31, 2021.[9] In November of 2020 it was estimated the conversion to gas could be completed by 2025.[10] Based on the company’s financial statements, the cost estimates of the selected conversion plan increased from 98 billion tenge (US$229 million) to 131 billion tenge (US$306 million) in 2021.[9] Coal ash waste storage on site may reach its capacity by 2024 which has been cited as one of several reasons to swiftly convert the coal units to gas.[3] In April 2021, the initial proposed project did not receive the government approval. One of the reasons was an increase in total estimated cost by more than 30 billion tenge.[11]

New proposal (pre-construction)

A new proposed project has been announced in July 2021 and includes construction of a new combined cycle gas power plant at the same location as the existing coal power station. The project is expected to undergo expert examination by December 2021 and is supported by the President of Kazakhstan.[12][13] According to a news source from November 2021, after the construction of the new gas-fired units, the coal-fired units will be mothballed and kept as a backup in case of emergencies. Construction is expected to start in the spring of 2022, and the first gas-fired unit is expected to be commissioned by the end of 2023.[14] The entire combined cycle unit is expected to be commissioned by 2025.[2] As of April 2022, the project proposal has been submitted for government approval but has not yet received approval.[15] The proposed capacity ranges from 250 MW[16] to 400 MW[2] to 600 MW[17], depending on the source.
