Feasibility assesment of a 10-MW grid-connected photovoltaic power plant for small industries: a case study in Iran

Development with the expansion of electronic devices, increased electricity consumption, and supplying the required power are some challenges involving different countries. Iran is also currently consuming in its industries that to supply electricity, it is necessary to adjust the program of various blackouts, hence the stoppage of the production of industries and mines has caused significant damage. This paper presents a comprehensive feasibility study for the construction of a 10-MW grid-connected photovoltaic (PV) power plant aimed at mitigating energy deficits in Iran's iron ore mining sector, particularly during blackout periods. Utilizing HOMER software for technical simulation, the proposed solar plant is projected to generate approximately 16 million kWh annually, with 2 million kWh available during shutdowns. Financial analysis conducted through CAMFAR software indicates a payback period of 8.6 years, an internal rate of return (IRR) of 12.67%, and a net present value of $3.45 million, underscoring the project's economic viability. The plant’s capacity to compensate for the production of 66,750 tons of iron concentrate during outages underscores its potential for significant financial benefits.
