Large Scale Ground Mount PV Power Plant in South Bosnia and Herzegovina – Various Scenarios of Project Development

Renewable energy sources (RES) penetrate rapidly in power systems. It is primarily referred to photovoltaic (PV) power plants and wind turbines. Today PV power plants have the highest share of RES. PV power plants became financially available in the last period regarding construction for wide spectra of investors due to low investment costs. It is primarily due to the decrease in the price of PV modules. This is case for Bosnia and Herzegovina too where is high interest for investment in PV solar plants today, primarily in Herzegovina region. Multiple financial parameters have an influence on PV power plant profitability. Financial parameters that were used in these analyses are installed costs, operative costs, discount rate, electricity price, inflation, tax profit and product variation. Variation of these parameters will be examined regarding financial results and project profitability. Financial results should help investors to adopt project or project variant. In this paper financial results in focus are NPV, ROI and DPB. Two case studies of PV power plant project were examined. In both case studies electrical equipment used is the same and the area for construction is unique. Row-to-row distance is technical parameter that was variable. This row-to-row distance affects generated electric power, shade losses and DC/AC ratio. Regarding financial results several scenarios were analysed. The proposed method can be a base for selection criteria by the investor regarding project case study acceptance.
