Electrocentrale Bucuresti S.A. (ELCEN)
  • ELCEN is both an electricity producer and a heat energy producer: it is the largest thermal (heat) energy producer in Bucharest (90% of the market) as well as nationwide (40% market share) and it had a 4.8% share of the national electricity market in 2014.
  • ELCEN was founded on December 18, 2002, as a subsidiary of Termoelectrica.
  • Ownership structure: Ministry of Economy through the Department of Energy (97.51%) and Romgaz (2.49%).
  • In 2014, ELCEN underwent a restructuring process and two other companies have been created through separation from ELCEN: Electrocentrale Constanta and Electrocentrale Titan. The division project was approved by the company Board on May 29, 2014 and was published in the Official Gazettte No. 3184 (Part IV) of June 4, 2014. This restructuring is a provision of the Memorandum adopted by the Romanian government in March 2013 that aims to develop a more efficient and high quality public service for residents of Bucharest and Constanta. According to the Memorandum, the next steps of this process would be to:
    • a) transform RADET (Autonomous Administrative Unit for Distribution of Heat – and the only distributor of heat) into a commercial entity (see Annex 1 for Heating Sources (TPPs) and areas supplied by RADET in Bucharest);
    • b) transfer the state-owned shares of Electrocentrale Bucuresti and Electrocentrale Constanta to Bucharest City Hall and, respectively, to Constanta City Hall;
    • c) merge the two companies (RADET and Electrocentrale) for Bucharest, respectively Constanta.
  • Following the 2014 restructuring, ELCEN now holds in its portfolio only 4 thermal power plants (TPPs) that service Bucharest, also known in Romanian as Centrala Electrica de Termoficare (abbreviated: CET):
    1.  Bucuresti Sud TPP
    2.  Bucuresti Vest TPP
    3.  Grozavesti TPP
    4.  Progresu TPP

Palas TPP, Titan TPP and Fantanele TPP are no longer part of ELCEN’s portfolio.

  • ELCEN Registration No. at Trade Chamber: J40/1696/2003;
  • ELCEN Fiscal Identification Code: RO15189596.

 

1. Bucuresti Sud TPP (CET Sud)
(6 units: 1 x 50 MW; 1 x 36.5 MW; 2 x 100 MW*, 2 x 125 MW)
Unit No. Capacity Current status Other relevant info
Unit 1 (1965) 50 MW Active The 4 units put in exploitation in the ‘60s (combined 300 MW, put into operation during stage I) have passed their designed lifetime (200,000 hours). Feasibility studies have been conducted in mid 1990s. In 1998 RENEL signed with EIB and agreement for rehabilitation of 2 x 100 MW boilers (at Unit 3 and 4). Project was awarded to Alstom Power and in early 2000s they have been modernized by a consortium made up of Alstom (France), Fortum (Finland) and Itochu (Japan). NOx reduction achieved. The retrofitted boilers have added 150,000 hours of operating lifetime.
Unit 2 (1966) 36.5 MW Active
Unit 3 (1966) 100 MW* Active
Unit 4 (1966) 100 MW* Active
Unit 5 (1975) 125 MW Active Another 250 MW (2 x 125 MW) have been put into operation in mid 1970s (stage II). However, according to the National Investment Plan, 1 unit of 125 MW will have to be decommissioned in 2018.
Unit 6 (1975) 125 MW Active

Location: Bucharest, district 3, Str. Releului nr. 2B

Total final installed capacity: 550 MW, power plant is hydrocarbon (heavy-fuel oil and gas) fired. CET Sud is the largest TPP of this kind in South-Eastern Europe, and represents half of the installed capacity that services Bucharest. The plant operates in cogeneration (supplying electricity and heat) to the capital. CET Sud produces 60% of the heat distributed in Bucharest, specifically to residents in southern districts (Balta Alba, Pantelimon, and Colentina).

  • According to the National Investment Plan (Annex 3), CET Sud is planning to build a new CCGT in 2014-2017.

*Note: In Ref. to Units 3 and 4, we found contradictory information re. their capacity. On the one hand, a 1999 governmental source (HG 416/1999) states that unit 3 and 4 have 100 MW capacity (each). But, according to another source, during stage I (1960s) were built: 1x 50 Mw and 3 x 36.5 MW (each). We believe that Unit 3 and 4 may have been initially built with 36.5 MW and later upgraded to 100 MW.

 

2. Bucuresti Vest TPP (CET Vest)
[2 units x 125 MW; 1 unit x 182 MW]
Unit No. Capacity Current status Other relevant info
Unit 1 (1975-‘76) 125 MW Active Mainly gas fired, fuel-oil-fired only for secondary /complimentary purposes. Unit 1 can use fuel-oil only in special situations regulated by GD no.440/2010 (art. 12.4)
Unit 2 (1975-‘76) 125 MW Active
Unit 3 (2009) 182 MW Inactive Unit went into scheduled revision on Sept 1, 2014 and is planned to re-enter into operation by the end of March 2015. The repair works were delayed by the supply of some faulty spare parts.

3. Grozavesti TPP (CET Grozaveṣti)
[2 x 50 MW]
Unit No. Capacity Current status Other relevant info
Unit 1 50 MW Active Both unit 1 and 2 are gas-fired. Although, natural gas is the main fuel, fuel-oil (pacura) with a <1% Sulfur content can be used for back-up. Fuel-oil (stored on location) is used only when the pressure in the natgas network drops and can sustain 100% the functioning of the boilers for 15 days. The boilers are equipped with mixed burners allowing to burn natural gas and fuel-oil separately or both at once.
