Performance evaluation of 5 MW Solar PV Power Plant in Kupang

Abstract

Government of Indonesia have target to achieve 23% share of renewable energy in National energy mix by 2025. As a part of the target, solar energy needs to contribute as much as 6.5 GW installed capacity in 2025. Therefore, Government of Indonesia develop policy to promote renewable energy, especially solar energy. In 2013, Ministry of Energy and Mineral Resources launched High Tariff Regulation for Solar PV Power Plant. The 5 MW Kupang Solar PV Power Plant is one of the result of the policy. It was the biggest Solar PV Power Plant project in Indonesia. This project located in Oelpuah District, Kupang Regent, in East Nusa Tenggara. This Solar PV Power Plant consist of 2,208 units of 230 Wp solar PV module manufactured by state owned company namely PT. LEN Industry and 250 units of grid inverter manufactured by SMA. Started operation in March 2016, this Solar PV Power Plant already contribute in national renewable energy share. By using the recorded data, evaluation of power plant performance conduct by using Performance Ratio calculation. During March 2016 to December 2019, the Plant have produced 25.3 GWh of electricity. Based on IEC 61724 methodology, daily Performance Ratio is between 0.7 and 0.9. In additionally, economic analysis of this Plant was calculated based on realization of project income. It shows that the investment will be returned by 8th year of the Plant operation.
