Project co-financed from the Norwegian Financial Mechanism 2014 - 2021, Energy Program in Romania

 

The internal consumption related to transformer stations, represents the consumption of internal services (busbars, transformer units). 

Internal AC services together with DC services ensure the operation of the stations' command and control systems, technological services (arming, pressure, ventilation) without which the stations could not operate.
The transformer station's own technological consumption, i.e. the consumption of internal services, contributes to a decrease in the efficiency of the electricity distribution process.

From the analysis carried out in order to identify the most favourable situation for the location of photovoltaic plants, two locations were selected: 110/20 kV Barbatesti station and 110/20 kV Bals station, the photovoltaic power plants being able to ensure the own technological consumption of all the stations on the contour, namely Pojaru, Stoina, Carbunesti, Turburea and Milcov, Slatina Nord, Iancu Jianu, stations which are interconnected by an 110 kV aerial electrical line.

The transformer stations where the project will be implemented are located in Oltenia, in the counties of Gorj (Barbatesti station) and Olt (Bals station), a region that ensures an adequate level of solar radiation, necessary for their equipment with photovoltaic systems.
 
Following the analysis of the electricity consumption (1.561.629 kWh/year) related to the internal services of the mentioned 110/20 kV stations and the available surfaces (8758 sqm), it is intended, in order to reduce the energy losses through OTC, to install photovoltaic plants with an installed power of about 810 kW

- use of renewable sources of electricity - estimated production of 1183 MWh/year;
- estimated annual reduction of CO2 emissions by 362 tons CO2 equivalent/year after implementation;
- reduction of energy purchase costs related to internal energy consumption;
- positive environmental impact generated by the construction of photovoltaic power plants;
- 2 employees will be trained to use the renewable energy installation - solar).

 

Total value of the project: 1.265.304 euro of which 20.400 euro is the ineligible value and the total eligible value is 1.244.904 euro of which 745.722 euro is the non-reimbursable eligible value. 
 
Investment value supported by Distributie Energie Oltenia: 519.582 euro eligible and ineligible expenses.
 

Project implementation period: 21 months, from 01.08.2022 to 30.04.2024.
