Isolated Grid With Peak Load > 50 MW: 1.Bangka, 2.Lombok, 3.Tanjung Pinang, 4.Palu.

3
Isolated Grid With Peak Load: MW: (1) Jayapura, (2) Sorong, (3) Ambon, (4) Ternate, (5) Kupang, (6) Sumbawa, (7) Bima, (8) Luwuk, (9) Gorontalo, (10) Kendari, (11) Kolaka, (11) Bau-Bau, (12) Bontang, (13) Sampit, (14) Pangkalan Bun, (15) Sintang, (16) Ketapang, (17) Belitung, (18) Rengat, (19) Tanjung Balai Karimun, (20) Sungai Penuh, (21) Takengon, Meulaboh

4
Isolated Grid With Peak Load: 1 – 10 MW There are thousands of them. Subdistrict Capital City With Peak Load: < 1 There are thousands of them. Small Town and in the Villages

5
Consequences of Having those Thousands Isolated Systems Avoided cost or BPP are huge different between grids. Highest: IDR 3.300/kWh in the Maluccus: Lowest: IDR 900/kWh in West Java. These figures are average figures for each region: an average cost large, medium and micro grids in the region. Micro grid with peak load < 1 MW Located in remote place. Consist of 1 diesel genset or several diesel gensets within capacity of tens or hundreds kW. Avoided cost could be > IDR Rp. 5,000/kWh.
