4 March 2010 -- Tenaska said its planned 602 MW Taylorville coal to gas-fired power plant would cost about $3.5 billion and enter service in 2014. The cost is around $5,800/kW.
Tenaska said the Taylorville Energy Center will use Siemens integrated gasification combined cycle (IGCC) technology to convert coal into a synthetic natural gas and then burn the gas to generate electricity. The conversion process would also separate pollutants such as sulfur dioxide, mercury and nitrogen oxide.
The power plant design uses carbon capture and storage (CCS) technology and would capture more than half of the greenhouse gases produced. Tenaska said the plant’s emissions would be comparable to a natural gas-fired plant of similar size.
Tenaska based its cost estimates on construction starting in December 2010, with the power plant entering service in December 2014.
Tenaska still needs an air permit from environmental regulators and the Department of Energy to complete its review. In July 2009, DOE selected the Taylorville project for a $2.5 billion loan guarantee.
The facility will be l on a 713 acre site near Taylorville in Christian County about 35 miles southeast of Springfield.
Christian County Generation LLC, a joint venture between Tenaska and MDL Holding Co of Louisville, Kentucky, is developing the project.
