Abstract

This research presents the concept of developing PLTMH with limited water discharge to become sustainable of Hybrid Renewbale Energy Systen (HRES). Hybrid of PLTMH - Solar Photovoltaic (PV) energy sources and limiting the energy use of each household carried out simultaneously in both the rainy and dry seasons are the solutions so that not only electricity supply can be sustainable but also low cost. The operation of the Hybrid Renewable energy system is not as simple as using PLTMH resources so a Hybrid Optimization Model of Electric Renewable (HOMER) application program is needed. This application program is used to calculate the Total Initial Capital, Cost of Energy (COE) and Excess Energy from HRES. This simulation uses an application program that refers to the lowest Net Present Cost (NPC) value with a life time of 25 years. The simulation result shows that the lowest NPC value is Rp. 863,974,768, the Total Initial Capital needed to develop PLTMH Resources to become HRES in Ambapa village is Rp. 392,470,986, -. The contribution of energy produced from PLTMH energy sources is 103,780 kWh/yr (84.20%) and PV energy sources is 18,810 kWh/yr (15.8%). The 100% total contribution is 122,590 kWh/yr with COE of Rp1,107/kWh. The cost of electricity is Rp. 48,238/month with the energy consumption limits per household of 1,450 wh/day.
