Abstract

The Indonesian government has issued the Minister of Energy and Mineral Resources (MEMR) Regulation 49/2018 regarding the utilization of rooftop solar power systems by customers of utility grid provider (PT Perusahaan Listrik Negara). The policy aims to encourage the penetration of renewable energy usage to reduce carbon gas emissions. This policy governs the general requirements and procedures for the installation of rooftop PV(photovoltaic) systems by utility grid customers. Therefore, economic analysis is needed to be known the impacts to the customers. This study will simulate the 4-storey office building which electricity supplied by grid connected 41 kWp of rooftop PV without battery storage under PV rooftop scheme using HOMER (Hybrid Optimization of Multiple Energy Resources) software. This case study simulate the new for Environmental Studies Center of Gadjah Mada University (PSLH UGM) building located in Yogyakarta, Indonesia. From this study will be obtained the value of the cost of energy (COE). In this simulation, the 41kWp rooftop PV supplies 485.32 kWh/day and 148.21 kW peak demand load. The cost of energy generated from on grid rooftop PV system is 1.431,00 IDR/kWh, while the grid rates is 1.468,00 IDR
