Jimah Power Plant (also known as Jimah East Coal-Fired Power Plant or Stesen Janakuasa Tuanku Muhriz) is a 2GW ultra-supercritical coal-fired power station situated in Port Dickson District, Malaysia.

History

In February 2014, Suruhanjaya Tenaga awarded the 2GW thermal power project to a joint venture between 1Malaysia Development Berhad and Mitsui. In July 2015, Tenaga Nasional acquired a 70% stake from 1MDB, ^{[1] [2]} and in January 2016, Mitsui sold a 15% stake to Chugoku Electric Power Company. ^[3] Construction began in 2015, with the first unit of the Jimah East power plant starting operations in August 2019, ^[4] and the second in December 2019. ^[5]

Operations

The power station consists of two 1,000MW ultra-supercritical coal-fired units, each with a once-through boiler and a 3000rpm steam turbine operating at 603°C and 270 bar. The units feature water-cooled stator, hydrogen-cooled rotor generators, a 160m-high chimney with 9.1m internal diameter, and on-site ash storage facilities. Emissions control includes seawater flue-gas desulfurization and electrostatic precipitators. ^[6] The station has a coal loading jetty for large capesize bulk carriers. ^[7]

Accidents

• On the early morning of 2 February 2017, during the construction phase, a transformer in Unit 1 at the plant's switchyard burst and caught fire. No casualty reported. ^[8]
