Mitsubishi Power has signed a series of contracts with Taiwan Power Company (TPC) for a large-scale renovation project at the Datan Power Plant in the city of Taoyuan, Taiwan.
Mitsubishi Power will renovate four units of the gas turbine combined cycle (GTCC) power plant (Unit 3 to Unit 6), comprising a total of eight gas turbines.

The aim of the renovation project is to reduce emissions of nitrogen oxide (NOx) to comply with environmental regulations, as well as to enhance operating flexibility.
The Datan Power Plant is one of the largest natural gas-fired power plants in Taiwan with a total of 20 gas turbines. Once complete, the plant will have a combined output of 7,000MW.
The renovation is scheduled for completion in 2025.
Reducing emissions
To reduce NOx emissions, the current combustors will be replaced with air-cooled, premix combustors (systems in which fuel and air are mixed in advance), which lowers the local combustion temperature and curbs NOx generation, decreasing NOx emissions by around 60%.
Mitsubishi Power will also utilise gas turbine components coupled with the TOMONI suite of intelligent solution services and will provide a turnkey solution covering handling the design, manufacture, installation, and testing of the auxiliary machinery.
Taiwan’s gas demand
According to Mitsubishi Power, Taiwan continues to face a tight supply and demand situation for electric power, with producers unable to keep up with robust demand.
The country needs to increase its capacity margin to cope with peak demand loads, placing high expectations on gas fired power generation.
Taiwan has adopted an energy policy that includes abolishing nuclear power by 2025, setting a target for 30% of electricity to be derived from fossil fuels, 50% from GTCC power plants, and 20% from renewables.
