The complex is the largest source of CO2 emissions in Bulgaria with over 10 million tons in 2024. The complex is politically controversial; it has badly polluted local towns but many people rely on it for jobs.
Maritsa Iztok-1 (TPS AES Galabovo)
Maritsa Iztok-1 is located near Galabovo. In October 1998, the old power plant with a capacity of 500 megawatts (MW) was privatized and sold to Consolidated Continental Commerce (3C), later purchased by AES Corporation. On 15 February 2000, AES and the Bulgarian grid operator Natzionalna Elektricheska Kompania EAD (NEK) signed a 15-year tolling agreement, according to which AES has an obligation to replace the old power station with a new facility. In June 2006, AES started construction of the new 670 MW power station. It became operational on 3 June 2011. The new power station consists of two pulverised coal boilers of 335 MW each, two steam turbines, two generators and desulphurisation facilities. The plant was constructed by Alstom. It cost €1.2 billion.

Maritsa Iztok-2
Maritsa Iztok-2 is the largest thermal power plant in the Balkans. It is located 60 kilometres (37 mi) from Stara Zagora in the vicinity of the village of Radetski and the dam lake Ovcharitsa. The construction of Maritsa Iztok-2 started on 7 May 1962; it was inaugurated on 10 November 1966. Between 1979 and 1995 the power station was expanded by four additional units. 1977 and 1980 two new 325 metres (1,066 ft) tall chimneys were built. Maritsa Iztok-2 has a total installed capacity of 1,465 MW and generates 30% of Bulgaria's electricity. It consists of eight generating units, two of which are equipped with flue gas desulphurization plants. The rehabilitation of the older power units, including construction of FGD plants for units 1 to 6, are in progress.
Maritsa Iztok-2 is wholly state-owned. It is a subsidiary of Bulgarian Energy Holding EAD.
In November 2014 the power station was ranked as the industrial facility that is causing the highest damage costs to health and the environment in Bulgaria and the entire European Union by the European Environment Agency.
In June 2019 a fire thought to be caused by routine maintenance broke out on the smokestack of the flue gas desulphurisation system at Unit 8.
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 ContourGlobal (73%) and NEK (27%).
