The overall objective of the project is to increase the distribution capacity by upgrading the 110/20/6 kV Ocolna Transformation Station, for the discharge of electricity produced by photovoltaic plants in the area. The main objectives envisaged for the modernisation of the transformer station are: A. Increasing the safety of electricity supply to consumers and improving the technical conditions for the uptake of energy produced from renewable sources and outlet in the National Energy System (SEN) B. Reducing Own Technology Consumption (CPT) by replacing existing equipment with modern, reliable equipment with low and energy efficient maintenance costs: power transformer, outdoor and indoor lighting, heating/climatisation, replacement of existing relays with low consumption numerical terminals. C. Increasing the takeover capacity of future renewable producers (the area having a high potential in terms of electricity generation using solar radiation). At the same time, the modernisation project also contributes indirectly to the LIOP 2S53 result indicator. Gross primary energy production from less exploited renewable sources, i.e. as a result of modernisation, is expected to increase the gross primary energy production from renewable sources by 5.48 GWh/year, from 9.75 GWh/year to the non-project variant to 15.23 GWh/year, respectively an increase from 0.824 thousand toe/year in 2019 to 1,295 thousand toe/year in 2024. Project contribution in absolute values 1,295-0,824 thousand toe/year = 0.471 thousand toe/year. Taking into account that the reference value of less exploited primary energy production from renewable sources is 455.96 thousand toe/year, the project contribution in relative values 0.471/455.96*100 is 0.103 %. The achievement of this general objective can be achieved only by setting specific measurable, realistic and achievable objectives that will be pursued throughout the project implementation period as well as during the sustainability period.
