About Us

Mintia Thermal Power Plant has been designed as a regulation power plant in the National Power System, and Paroșeni Thermal Power Plant - as a restart power plant for the power system in Romania, so they have been thought out to operate as strategic points in the National Power System. Their merging in one economic entity - Complexul Energetic Hunedoara - makes Hunedoara County an important player on the regional energy market.

Electrocentrale Deva

Deva Thermal Power Plant is located in the South-Western part of Transylvania on the Mures River at a distance of 9 km from town of Deva. The plant has an installed power of 1285 MW, consisting in four power units of 210 MW each, plus one unit of 235 MW supplied by steam boilers of 660 t/h, 13,72 MPa, 550 °C, each unit is independent. Four of them are endowed so that they can cogenerate in a 210/160MW system for delivering steam through adjustable 1,2; 2,5 and 6 bar intakes. The extracted steam is used in the heat exchangers for preparing the heat carrier in the main network, having an adjusting diagram with peak temperatures of 150/70 °C.

vedere generala

The building of the plant had been justified mainly by the necessity of supplying electricity in a high industrialized area, taking into consideration the possibility of being fed with fuel from the Valea Jiului coal field. When this location was chosen, it had been taken into account the advantage of using the conditions provided by Mures River - the accomplishment of a cooling water open network and the connection of the plant to the railway and national road Arad - Deva.

The construction works started in 1966 and the commissioning of the plant had been performed in three stages:

  • 1969 1971 - four units of 210 MW and a micro-hydro power plant with an installed power of 1,35MW.
  • 1971 – 1984 - the endowing of the plant with equipment requested for thermal energy and electricity cogeneration.
  • 1977 – Unit no. 5 - 210 MW.
  • 1980 – Unit no. 6 - 210 MW.

Each unit is endowed with 330t/h steam boilers operating on hard coal firing. The rated hourly consumption per unit and the resulted slag quantity may vary between 25 - 35%.

The power is delivered into the National Power System through an interconnection station - Mintia - of 110kV, 220 kV and 400 kV. The power plant was commissioned in three stages:
  • 1969 1971 (stage 4x210 MW)
  • 1977 Unit no. 5 - 210 MW
  • 1980 Unit no. 6 - 210 MW

Unit no. 3 was rehabilitated in 2009 up to 235 MW.

Unit no. 1 was withdrawn from operation in 2012.

District Heating Deva

The District Heating Department within Complexul Energetic Hunedoara supplies primary heating power for 52 urban heating plants, 35 of them belong to C.E.H., and are completely rehabilitated, and the others belong to some economic operators under contract with the company.

For acquiring the thermal power at the installed power, the urban heating plants are endowed with heat exchangers with high efficiency pumping panels and units.

The secondary network that provides heating distribution (heat carrier with an adjusting diagram at the consume peak of 95/75 °C and waste hot water with a maximum temperature of 60 °C) from the urban heating plants to the consumers, supplies the apartments mainly situated in buildings of 3 to 10 floors.

  • 1984 – the commissioning of the urban heating installation and the heat carrier transportation network.
  • 2000 – 2007 - the replacement of the secondary urban heat carrier transportation networks.
  • 2001 – 2005 - the rehabilitation of the urban heating plants by replacing the pumping units and heat exchangers.

At the end of 2012 the heating services and waste hot water consumers were:

  • 6096 flats, of which 350 are individually metered
  • 262 economic operators
  • 12 education institutions
  • Hunedoara County Hospital (Deva)

After '90s many people chose to have apartment gas heating systems, but the gas price increase and the thermal networks rehabilitation convinced them to turn back to the urban heating system. At the District Heating Department are many requests coming from Owners Associations in Deva, for connecting to the urban heating system and installation of individual metering devices.

Paroșeni Thermal Power Plant

The development of Jiu Valley, in all respects, has been closely linked to the exploitation of coal fields. The first exploitation works of coal  fields from Jiu Valley were performed in 1848 by brothers Hoffman and by Carol Madersbach, mine owners in Rusca Montană, attracted by the discovery of coal in the valleys of rivers.

At the beginning of 1867, the works for Simeria-Petrosani railway started, achieving through this a modern means of transportation, as the railway engine started to use coal from Jiu Valley. Consequently, it started the boring of side galleries in Petroşani-Est and Petrila mines.

  • 1872 – it is installed at Petrila the first steam extraction machine, and in 1890 the road Petroşani - Târgu-Jiu was opened for traffic.

During this period, coal exploitation works were performed at Lupeni, Vulcan and Aninoasa by various companies.

  • 1900 – in Vulcan, it is commissioned the power plant equipped with a 100 kVA generator.
  • 1908 it starts the building-up of the entire power plant, designed to replace the temporary one that was built in 1900 and enlarged in 1905, having the purpose of feeding the mines from Petrosani, that were not receiving enough power from their own plant, of 500kVA.
  • 1910 1912 - in the north-eastern area of Petrosani, two turbo generators of 3700 hp were installed in the power plant. Therefore the power from Vulcan plant is increased due to a third generator of 450 kVA.
  • 1914 the electrification of Lonea-Petrosani industrial railway is accomplished.
  • 1926 – the electricity required to produce compressed air in the mines belonging to Lupeni Company was generated by 4 turbo aggregates, summing up 9.4 MW.

In the years during the Second World War, coal production increased every year, reaching a peak in 1943 of 2.755.880 tons. In 1943, Vulcan power generating station is equipped with a new turbo generator of 13.3 MW.

  • 1950 – the cover of energy needs in the region is achieved by the existing power plants in the area, especially of Vulcan power plant. Its facilities were outdated and the power plant was far from meeting the future needs.

The power requested by developing mine exploitations and coal preparing plants, increased in 1955 to 50 MW, and in 1960 to approx. 55 MW.

Building a hydroelectric plant in a short time in this region was not possible; therefore it remained the solution of a coal power plant, especially since in the region there have been large coal supplies.

The settlement of Paroseni power plant was chosen “at the bank”, and by connecting the 220kV overhead power line with Targu-Jiu station, it was envisaged the interconnection between Oltenia and South-West Ardeal power systems.

  • 1953 – it starts the site arrangements for building Paroseni TPP.
  • 1956 – commissioning of the first unit of 50MW in the country, at Paroseni, a condensation turbine VK-50-1 type of 220 t/h, 500 ºC, 90 bars, with air cooled generator and 10,5 kV terminal voltage
  • 1956 – commissioning of 110 kV Paroşeni- Bărbăteşti overhead power line, with first operation at 35 kV and of the 35 kV Bărbăteşti – Rovinari power line, with 35 kV station Rovinari, and by this, the first connection to the National Power System of North Oltenia region and Paroşeni-Oţelu Roşu – Reşiţa power line of 110 kV and by this, the connection to the National Power System of Banat region. The first station and overhead power line of 110 kV in Banat.
  • 1957 1959 – commissioning of power units no.2 and 3 of 50 MW, similar to unit no. 1, forming the 1st stage (3 x 50 MW).
  • 1963 – it starts the site arrangements for building unit no. 4 of 150 MW.
  • 1964 – accomplishment of works at boilers 4 and 5, Ramzin type, with forced circulation, with intermediate overheating, steam flow of 270 t/h/each, 570 ºC, 140 bars, type PK-38-2, and at the condensation turbine no. 4, PVK - 150 MW type, steam flow of 540 t/h, 565 ºC,130 bars, with hydrogen cooled generator type TVV-165, forming the second stage.

The first power unit of 150MW in the country and the largest one at that time, Paroseni TPP was the first Romanian power plant, with an installed power of 300MW.

  • 1979 – in order to supply thermal power to various localities in Jiu Valley, based on the study drawn-up by the Institute for Studies and Power Engineering (ISPE) Bucharest, it is opened the financing of the investment works, so as to change those three condensation turbines of 50MW into district heating turbines. During this time, there were commissioned the main boilers, the district heating pumping station and transportation pipelines for the heat carrier, under the form of hot water, namely:
- Pipeline Paroşeni – Petroşani (DN 900 mm);
- Pipeline Paroşeni – Lupeni (DN 500 mm).
  • 1981 1982 the heat carrier under the form of hot water was supplied to Vulcan town and to a part of Petrosani town
  • 1982 1983 – the works related to the transformation of the condensation turbine into district heating turbine with adjustable intake were accomplished. During this period of time, Lupeni town is connected to the district heating network. Paroseni TPP become then the single heating source that supplies heat to Lupeni, Vulcan, Aninoasa and Petroşani.
  • 1989 power unit 4 was decommissioned because of modernisation and investment works aiming to transform the condensation unit no. 4 into a district heating unit, respectively 156 MW and 150 Gcal/h.
  • 1999 – it was commissioned a hot water boiler of 103,2 Gcal/h. This boiler is operating on coal, namely hard coal from Jiu Valley, with methane gas add-on, being a prototype in Romania.

According to „National Strategy of Development”, to the governmental programmes as well as to the “Romanian energy roadmap”, Paroseni TPP was included into the rehabilitation and development programme for power unit 4 of 150 MW, with external financing, its transformation from condensation unit into cogeneration power unit as well as the decommissioning, inventory and improvement of the 3 x 50 MW stage;

  • By G.D. 1192/2000, it was approved the Integrated Project for Jiu Valley with foreign financing by the Japanese ITOCHU-HITACHI-TOSHIBA CORPORATION, aiming the exploitation of coal from Jiu Valley in new cogeneration units, of high efficiency
  • Building and commissioning works for unit 4 took place during March 2004 – September 2006, and from August 2007 power unit 4, Paroseni was put into commercial operation.
