Panel Discussion :
How do we go forward to implement the utility-scale
Solar-PV-Diesel Gen-set Hybrid Power For Micro/Mini Grids in Indonesia
as Independent Power Producers with PLN as off-taker,
with the current BPP (LCOE) prices and regulation?

-

Identify the microgrids/ business opportunities
Make pre-FS for each grid, including preliminary PV hybrid system design
Discuss with the PLN
Begin permitting process (including Environmental Social Impact Assessment)

Begin land acquisition process
Make FS and Interconnection Studies
Get approval from PLN Wilayah, Regional and Pusat
Participate in the Direct Selection/Appointment process in the microgrids according to the
regulation
- Implement
