Ulsan Hanju power station

From Global Energy Monitor

Ulsan Hanju power station (울산 한주) is a 155-megawatt (MW) combined heat and power (CHP) coal-fired power station in Ulsan Province, South Korea.

Background

Hanju Corporation is an industrial complex collective energy provider that supplies heat and electricity to the Ulsan Petrochemical Complex. It was established in 1972.[1] It underwent coal expansion projects in 1991 and 1994, and a “BC oil” expansion phase in 1998.[2]

The complex appears to operate a 155-megawatts (MW) cogenerating coal-fired power station (50 MW, 40 MW, 40 MW, and 20 MW units).[3]

However, there is some uncertainty regarding the total coal capacity and exact fuel mix. For example:

  • in 2005, the facility appeared to feature 165 MW of capacity;[4]
  • Platts Market Data (S&P Global) includes six coal units at the site commissioned in 1972, 1993, 1994, 1998, and 2015, for a total of 156.7 MW (17.5 MW, 17.5 MW, 40 MW, 6.5 MW, 50 MW, and 25.2 MW);
  • Another source notes that the site includes two Fuji turbines and two Siemens turbines (50 MW, 40.6 MW, 40 MW, 17.5 MW).[5]

Upgrades

In 2013, Hanju Corporation ordered a steam turbine generator with a rated output of 25.2 MW as part of a new boiler and steam turbine generator construction project. The project aimed to improve energy efficiency of the plant by 2015.[6]

Ownership

Hanju Corporation reportedly started out as the Petrochemical Support Corporation established in 1969 to strengthen the competitiveness of Ulsan Petrochemical Industrial Complex by centralizing utility production. It started supplying utilities in 1972. In 1983, it built a refined salt plant and started to produce salt. In 1987, according to the government's privatization policy, Ulsan Petrochemical Support Co., Ltd. was established and the salt factory was sold. Then, in 1991, 1994, and 1998, the combined heat and power facility expansion project was carried out in three stages. After retaking the sold salt factory, the company changed its name to Hanju Corporation. Hanju’s utility business division also completed the construction of LNG fuel facilities in 2012.[2]

Proposed gas expansion

In March 2021, Hanju obtained permission from the Ministry of Trade, Industry and Energy to expand the combined heat and power (CHP) power station by 144 MW (57 MW for gas turbines × 2 units, 30 MW for steam turbines × 1 units). The proposed LNG capacity was described as an “unavoidable choice for the industrial cogeneration industry, which is suffering from the burden of switching to eco-friendly fuels rather than coal, which emits a lot of fine dust and pollutants” (Google Translate). When the LNG cogeneration plant is complete, Hanju plans to install a 1km pipeline to supply heat to the Bugok Yongyeon District.[3]

As of 2021, an environmental impact assessment was underway and the expansion was expected by 2023.[7]

The proposal appears separate from the Ulsan GPS power station (Bugok Yongyeon District) by SK Gas.

In 2021, a KEPCO brochure listed “HANJU CCPP EPC Project” with Hanju. Co., Ltd as a client and May 2021 to February 2024 as the project period. The brochure did not provide any additional details about the CCPP project.[8]
