The Erdenet power station was originally a 35 MW coal plant built in 1988.[2] It is located between a mining and residential area, and uses sulfur coal from the Sharingol and Baganur strip mines.[3]

A May 2014 brochure for the Energy Mongolia International Conference & Expo referred to an expansion of the Erdenet power plant as one project for which international investment was being sought.[4]

In March 2016, it was reported China’s Hunan Industrial Equipment Installation (HIEI) and the Ministry of Energy planned to expand the plant to 50 MW total. Around 85 percent of the investment is a Chinese concessional loan (to be recovered in 7.5 years), with the remaining financed by Development Bank of Mongolia.[5][6]

A groundbreaking ceremony for an expansion of the plant to 50 MW was held in March 2019.[7]

As of October 2020, the Mongolian government reported the renovation project was 90% complete and on track for commissioning in 2021.[8]

In September 2021, a completion and commissioning ceremony of the China-funded expansion appeared to be held in Erdenet.[9][10] In November 2021, Mongolia's Minister of Energy confirmed that there had been a 35 MW expansion of the plant.[11] Including three original units totaling 36 MW, the newly expanded power station reportedly had an installed capacity of 71 MW.[10][12]

According to an October 2022 Mongolian News Broadcaster story, the power station had just over one week of coal reserves and had an operating loss of 10 billion MNT ($291,913 USD) within the last year.[13] In November 2022, the Chief Engineer of the Erdenet power station stated that reserves were at 14 days, compared to 50,000 tons of reserves at the same time the year prior. He mentioned that though coal supplies were an issue, the turbines and furnaces were working without problem.[14]

In February 2023, a fire broke out at the station's furnace room. There were no injuries and the station was able to continue with normal operations.[15]


  • Source of financing: US$51.8 million in debt from the Export Import Bank of China;[8] US$600,000 in debt from the Development Bank of Mongolia; US$600,000 in equity from Chinggis bonds issued by Mongolian Ministry of Finance[16]

This expansion project was projected to cost US$53 million.[16] A US$51.8 million loan was provided by the Export Import Bank of China.[8] The rest of the funding came from a loan from the Development Bank of Mongolia and equity from Chinggis bonds, which are issued by the Mongolian Ministry of Finance.[16]
