Maritsa Iztok-3

Maritsa Iztok-3 is Bulgaria’s third-largest power plant. It is located 40 kilometres (25 mi) from Stara Zagora. The power plant has an installed capacity of 900 MW, which is produced by four units of each 225 MW. It has a 325 metres (1,066 ft) tall chimney.

In 1998, the United States power utility Entergy Corporation purchased 73% of Maritsa Iztok-3 shares for US$375 million from the Bulgarian state. Entergy also has the obligation to modernize the power station. In 2002, the Italian power company Enel joined the project; in 2006 Enel acquired Entergy's stake. At present, Maritsa Iztok-3 is owned and operated by Energiina Kompaniya Maritsa Iztok 3 AD, a joint venture of Enel (73 %) and NEK (27 %).

Enel is planning to invest in a new 700-800 MW coal-fired power plant next to the existing Maritsa Iztok-3 plant. The new power plant is expected to cost €900 million.
