Construction

The power station was constructed between 1983 and 1986 by a consortium of French Alsthom-Atlantique and Stein Industries, Russian Energomachexport and Zarubezhenergoproekt and Greek Biokat. It consists of two units with a generation capacity of 300 MW each.

Operation

The power plant's first unit has been in operation since January 1987 with the second unit following in August 1987. Its lifespan is limited by the remaining exploitable deposits in the Amyntaio mine. As PPC requested article 33 ''Limited lifetime derogation'' status for its Amyntaio and Kardia plants, excluding them from compliance with stricter emission limits set by the EU directive 2010/75, they are expected to be shut down by the end of 2023. In 2013, the Greek government included the Amyntaio power plant in a list of assets which PPC was required to spin-off to a subsidiary. This subsidiary was set to be turned into a new competing electricity company following its privatization. Following large scale protests and limited corporate interest in entering the Greek lignite market, the new Syriza-led government however announced it would call off the privatization.

Cogeneration of Heat and Power

The power station is equipped to make productive use of excess heat, supplying the nearby town of Amyntaio and the villages of Filotas and with co-generated district heat. Connecting to the power stations steam pipelines, the municipal ''District Heating Company of Amyndeo'' operates an extensive network connecting 1250 public and residential buildings. Originally constructed in 2005, the district heating network is currently being expanded by a planned 50% to cover a larger share of the three villages' heating requirements. Accordingly, the equipment is being upgraded to allow for thermal loads up to 34 MW_th. The Amyntaio district heating project is the third project of its kind in Greece following similar projects in

emissions remains high, in spite of moderate investments in filtering technology. Since 2001, NOx emissions of the Amyntaio power plant even significantly increased, reaching 2.5 kg/MWh in 2008, the highest value of all power plants in Greece. This is explained by the low and further decreasing calorific value of the low-quality lignite of the Amyntaio coal mine, which however has been found low in sulfur and mercury. After a pollutant emissions reduction plan as required by EU directive 2001/80 has been approved, the environmental permits of Amyntaio were renewed in 2008. With its lifetime being limited to 2023, the Amyntaio power plant however remains excluded from compliance with the stricter emission limits set by the EU directive 2010/75. Subsequently, neither the implementation of desulphurisation technology nor the replacement of
