In August 2005 and June 2006, 550 MW sub-critical pressure units 9 and 10 were installed on the adjacent land reclaimed by depositing ash.

[8] The boiler for each unit is drum type, water-cooled, naturally circulated with dry bottom furnace, balance draft and coal and oil-fired capability.

The steam turbine for each unit is a tandem-compound with four flow exhaust, single reheat and 550 MW rated capacity.

[10] The power plant is designed for base load service and is able for daily startup and shutdown operation.

Taipower buys most of the plant coal supply through long-term contracts from Australia, United States, South Africa, Indonesia and other sources.

[12] During warnings by the scientific community about increasing prevalence of lung cancer in Taiwan in December 2015, it was claimed that Taichung Power Plant along with the Sixth Naphtha Cracking Plant of the Formosa Plastics Group account for roughly seventy percent of the air pollution in the Central Taiwan region of the country, emitting large quantities of sulfur oxides.

[14] Additionally, anywhere from two to four coal-powered units will be decommissioned by 2030 in order to align with the government's policy of air quality improvement.

[18] On 8 November 2010, the power plant won the outstanding award at the 23rd National QCC Competition, organized by Industrial Development Bureau of the Ministry of Economic Affairs.
