The power station is owned by Mytilineos.[1] The facility is comprised of 2 units, a 445 MW combined cycle unit[1] and a 334 MW CHP unit[1].

In 2019, Mytilineos announced a proposed 826 MW expansion of the facility.[2] The new unit is proposed to be a combined cycle unit that is "hydrogen-ready" and was, as of 2020, expected to be completed in 2021.[2][3][4] However, as of December 20, 2021, the Mytilineos website stated that the new unit would start operation in 2022.[5]


In July 2020, the European Investment Bank signed a €125 million loan for the combined cycle unit.[6] In September 2021, the European Bank for Reconstruction and Development granted a €75 million loan to finance the construction and operation of the power plant.[7]

Coal project blocked

Previously there was a proposal to build a 600-megawatt (MW) coal-fired power station at the site, at an estimated cost of 890 million euros. The proposed coal-fired power station was sponsored by Mytilineos and Endesa, which had formed a joint venture company named Endesa Hellas.

A securities analyst reported in May 2007 that the company had submitted an application for a power generation license.[8] In July 2007, Endesa Hellas reported that the company aimed to have the "clean coal" plant online by the first half of 2013. (It also flagged that plans for a "clean coal" plant of unstated capacity were under development for a location in Albania).[9]

The project was effectively blocked in 2009 due to a decision by the Greek government to end hard coal imports in favour of using natural gas in future plants.[10]
