Techno-Economic Analysis of on Grid PV Power System for Vocational Training Institute in Baluchistan Pakistan to Reduce the Cost of Energy

Abstract

The Islamic Republic of Pakistan is a federation of five provinces, and Baluchistan is the largest province. It covers almost 40% of the total area of Pakistan. The critical issue relating to local power generation through renewable energy is the absence of area-specific production capacity and economic viability data for the different renewable energy technologies. This paper addresses one of the issues by assessing the area potential and economic feasibility of external electrification of the vocational training school building by using an on-grid PV system with net metering for bidirectional energy transportation. The economic feasibility reveals that the electricity generated using solar PV costs Rs. 4.89 per kWh with a NEPRA feed-in tariff rate of Rs.8.64 per kWh to sell back electricity to the distributor company. It is considerably cheaper than conventional electricity, which is now Rs.22.65 per kWh for a sanctioned load above 5KW. Similarly, the current solar PV system is easy to install and environmentally friendly also reduced CO2 emissions by 5030 kg, SO2 by 21.8kg and NOx by 10.8 kg per year.
