A second Siemens HL class turbine for South Korea

1 February 2022

Siemens Energy has received another order to deliver its HL-class power plant technology to South Korea. The equipment will be used in the Eumseong Unit 1 combined cycle power plant, which will be built in Eumseong in northwestern Chungcheongbuk-do Province.

The CCPP will be built in place of a previously planned 1000 MW coal-fired power plant that was cancelled following a change in the South Korean government's environmental policy. The switch to a high-efficiency gas-fired power plant should reduce CO2 emissions by up to 3.7 million tons per year compared to a similar coal power plant. The client is Korea East-West Power Co, Ltd, a subsidiary of South Korea's state-owned utility Korea Electric Power Corp. (KEPCO). The new plant is scheduled to be commissioned in late 2024

Eumseong Unit 1 is the first of two planned CCPP units and will have an installed capacity of 571 MWe. The power plant is designed as a single-shaft unit firing re-gasified liquefied natural gas (LNG). Siemens' scope of supply includes a SGT6-9000HL gas turbine, a SST-5000 steam turbine, a SGen-3000W generator, and the SPPA-T3000 control system

The order also includes a long-term part management contract for the gas turbine, technical field advisory services, and digital services including diagnostics services, continuous performance optimisation, and compressor condition performance-monitoring aimed at improving asset utilisation, reliability, and availability while also reducing operating and maintenance costs

EPC specialist POSCO E&C will be responsible for constructing the entire plant.
