REEP2 supports Indonesia in improving the institutional, regulatory, and technical conditions to reach 23 percent renewable energy in the national energy mix by 2025. REEP2 has three areas of intervention:

• Output 1- Improve the regulatory framework to promote decentralized renewable energy (RE).

• Output 2- Support PLN in power system planning and operation with high shares of renewables.

• Output 3- Promote RE pilot projects through cooperation with the private sector.

REEP2 combines a bottom-up and top-down approach by combining policy advisory work for renewable energy regulation with the demonstration of innovative RE solutions in selected locations. Following the regional approach of REEP, in its second phase, the project focuses on three target regions, Sulawesi, East Nusa Tenggara (NTT), and Bangka Belitung, with good replication potential. 

REEP2 also supports PLN in power system planning and operation with high shares of variable renewables while providing technical training PLN in assessing the local grid's capacities to incorporate higher shares of variable renewable in PLNs' in-house institutes. In this regard,

REEP2 supports the state-owned electricity providers in order to replace fossil fuel options. Related training programs are incorporated in PLN's in-house training institute to distribute skills and knowledge across the PLN corporation.
