The Prunéřov I Power Station, the older of the two, began operations between 1967 and 1968. It consisted of six 110 MW units. Between 1987 and 1992, four of these units underwent extensive reconstruction, and the remaining two units were decommissioned during the capacity phasing-out program in the early 1990s.<ref name=cez/>
The Prunéřov II Power Station is ČEZ’s newest fossil power station. It consists of five 210 MW units which have begun operations between 1981 and 1982.<ref name=cez/>Three of the units are being expanded to 250 MW (detailed info below).
The power station is fueled by brown coal from the Nástup Mines of Tušimice and Severočeské doly, a.s. (North-Bohemian Mines).<ref name=cez/> ==Climate impacts==According to the study ''Dirty Thirty'', issued in May 2007 by the World Wide Fund for Nature, Prunéřov Power Station is the twelfth-worst power station in Europe in terms of the relation of energy efficiency to carbon dioxide emissions.<ref>[http://assets.panda.org/downloads/european_dirty_thirty_may_2007.pdf The ''Dirty Thirty'' report]</ref> The power station is the largest single source of CO2 in Czech Republic.

In 2010 [[CEZ]] announced plan to retrofit and expand Prunerov II. The plan was challenged by Micronesia on the grounds that the expansion of the power station has impact to the climate and through this to the environment of Micronesia. Micronesia requested a Transboundary Environmental Impact Assessment.<ref>[http://www.upi.com/Science_News/Resource-Wars/2010/01/19/Micronesia-challenges-Czech-coal-plant/UPI-82581263927614/ Micronesia challenges Czech coal plant] UPI, Jan 19, 2010</ref> According to the Czech environment ministry that modernization plan does not include best available technology.<ref>[http://portal.gov.cz/wps/portal/_s.155/7226/_s.155/10202?docid=120244 Navrhovaná technologie pro modernizaci Prunéřova II není dostatečná]</ref>
In March 2016 CEZ reported that "In the Prunéřov Power Plant renovation project, installation work was completed and commissioning is underway (complex testing is underway at B23 and B24 units, first synchronization of B25 unit was performed on Dec 19, 2015)." Full commercial operation of the renovated units is planned for 2016.<ref>[https://www.cez.cz/edee/content/file-s/pro-investory/informacni-povinnost-emitenta/2016-03/cez-014-2016_en_46xyvz7z7s46vhxz.pdf "Press conference on CEZ Group financial results,"] ČEZ Group, Mar 15, 2016</ref>
