Marketing study regarding the possibilities of SC Termoelectrica units to be competitive on Romanian free energy market in the next five years
Short description:
The main scope of the study was to evaluate the possibility of each unit of TERMOELECTRICA to participate on the free Romanian market in the next five years.
The study has estimated the balances of capacities on main analyzed levels meaning: night goal(GN), morning peak( VD), night peak(VS), day goal(GZ) for the characteristic days.
In order to establish the loading order of the Romanian units, the analysis started with the estimation of the energy demand consumption for the analysed period, this evaluation was based on the document
” Romanian power strategy for the period 2007-2020.
The sold export –import was considered at a constant level of 3 ThW for the next years.
The coverage of estimated energy demand for the period 2008-2012 was achieved with WASP programme.
The minimum cost analysis is carried out with the aid of the Wien Automatic System Planning Package ‘WASP’ version IV generation planning software which is an industry standard generation planning software used to determine the optimal capacity expansion up to 30 years ahead, subject to given constraints.
The model uses the minimum costs evaluation method taking into consideration the investment costs, fuel costs and O&M costs.
In this study were analyzed 2 scenarios as follows:
• First scenario (basic scenario) in which the nuclear, hydro and thermal units participate in free competition, without restrictions to cover the load duration curve, (economical order), this is an development scenario with minimum costs. This is a theoretical loading order, because don’t took into consideration the Romanian concrete conditions regarding the domestically use of primary energy resources and lead to the decreasing of energetically independence degree.
• The second scenario in which it is imposed the loading order of the units so to consume the domestic lignite and hard coal, in correlation with the estimated demand.
In the Basic Scenario (economical loading order), only unit 4 from Paroseni power plant is in operation.
In the Scenario with restrictions, in which the loading order of the units it is achieved taking into consideration of some necessaries restrictions for maintaining an imposed level of import/export resources balance, the unit nr.4 from Paroseni power plant is in operation in all analyzed period (2008-2012), while the other units belonging to TERMOELECTRICA (Braila, Doicesti, Borzesti) are in operation having a considerable hours of operation.
These units are in operation because a significant part of the units are out of operation for rehabilitation and installation of FGD.
After these units will be back in operation after rehabilitation, the TERMOELECTRICA’s units will operate as before 2010.
Services offered:
The study analyzed the TERMOELECTRICA units probability to participate to the Romanian free market in the next five years.
The analysis show that the TERMOELECTRICA units from Braila, Doicesti and Borzesti power plants belonging operate as buffer units for the system, in the dry years or when the thermal units are out of operation due to the rehabilitation works in the big condensing power plants (Turceni, Rovinari, Deva etc) even their O&M costs are bigger.
In the free market condition the coverage of the low capacity can be achieved by energy import at low prices, in this situation only unit nr. 4 from Paroseni power plant from TERMOELECTRICA will be in operation.
Estimated technical performances:
The estimated operated performances for the TERMOELECTRICA‘s units were notified by TERMOELECTRICA through the letter 12145/ 26.10.2007.
The data were processed in the necessary form for WASP model.
