Agios Dimitrios Power Station is a power plant located near Agios Dimitrios, Kozani, Greece, situated between the towns of Kozani and Ellispontos village. In terms of its location in relation to a metropolis, the plant lies 140 kilometres (87 mi) west of Thessaloniki, a major city in northern Greece.

The Agios Dimitrios Power Station is the largest of Greece's power plants, generating a total capacity of 1,600 MW from two 300 MW units (Units I and II), two 310 MW units (Units III and IV), and one 365 MW unit (Unit V).[1] In terms of physical size, the three flue gas stacks of the facility are 200 metres (660 ft) tall. The plant burns lignite extracted through opencast mining, a process undertaken at the Lignite Center of Western Macedonia, which is located in the Ptolemais-Amynteo region, the main coal mining area of Greece.

The station is owned by the Public Power Corporation (PPC).

Unit V

Unit V was added to the existing four units of the Agios Dimitrios plant to be connected to the 400 kV outdoor switchgear, to increase the supply energy to the Greek national transmission grid. It is a unit of 350 MW electric, plus 70 MW thermal for district heating purposes.

In 1993, PPC awarded the contract for the supply and installation of Unit V to the consortium of the companies Ansaldo GIE (consortium leader - Italy, at present (2008) Ansaldo Energia a Finmeccanica Company), Austrian Energy and Environment SGP/Waagner-Biro GmbH (Austria) and AEGEK (Greece).

Main steps of the contract execution were:

  • 6 kV initial electrification - August 1996
  • boiler first ignition - February 1997
  • unit first synchronization - May 1997
  • official opening - October 1997
  • commercial operation - December 1997

In May 1995, the Kozani area suffered an earthquake of 6.6 degrees on the Richter scale, which affected the progress of the work.

Contract and project management

The contract was signed on March 31, 1993, by Th. Xanthopoulos, PPC general manager, Vincenzo Vadacca Ansaldo, GIE managing director, Heinz Zaunschirm and Helmuth Palzer, A.E. & E./Waagner-Biro directors and John Triadafillou, AEGEK managing director.

For the contract performance phase, the management of the project was provided by a project team composed by Roberto Pisani as project director, appointed by the consortium leader Ansaldo GIE, and Klaus Zink and Costas Latsenere as project managers, appointed by A.E. & E. and AEGEK respectively. At the plant, Salvatore Brozzas and Giorgio Simoncin were appointed by the consortium leader as site and start-up managers interfacing with S. Spaniolas, the Unit V construction manager of PPC. Project activities were supported by Vincenzo Gaiaschi and Konstantinos Keramidas in the consortium office of Athens led by Giorgio Mazzoni. Ansaldo GIE, consortium leader, played also the role of plant architect engineer, assigning to Roberto Masi this duty as project engineer.

On October 18, 1997, the unit was officially opened with the presence of Costas Simitis Prime Minister of Greece, Enrico Pietromarchi Italian ambassador in Greece, Fabrizio Pignatelli Italian consul at Thessaloniki, and with other representatives of the Greek parliament and local authorities.

Scope of supply

Object of the contract between PPC and the Consortium was the design, engineering, manufacture, supply, transportation, installation, testing, putting in operation and delivery of one lignite-fired steam electric unit of 350 Mwe plus 70 MWth in the Agios Dimitrios plant, including the design, engineering, construction and supervision of the civil works.

The project included the following main equipment, systems and works:

Greek companies as Aspate, Mekasol, Metka e Rodax participated in the construction of the unit as subcontractors of the three consortium members.
