Overview
The passage of the Energy Law of 2007 (Law No.30/2007) outlined Indonesia’s energy policy priorities and laid the basis for renewable energy deployment in the country (IEA, 2017). In 2021, Indonesia announced a target of reaching net zero emissions by 2060 or sooner, bolstering its commitment to the energy transition (Climate Action Tracker, n.d.). In recent years, energy self-sufficiency has emerged as a key objective for the Indonesian government, resulting in a renewed focus on coal power given the country's vast endowment. At the same time, the government has also focused on advancing decentralized renewable energy and announced a program in 2025 to develop 100 GW of solar power capacity along with battery energy storage systems (BESS), which will be anchored by 80,000 village cooperatives (Institute for Essential Services Reform, 2025). While the program signals the government's commitment to accelerate renewable energy deployment, several regulatory and institutional barriers must be addressed to effectively scale-up solar and wind energy in the country.
Key barriers and solutions
The key barriers to wind and solar power deployment in Indonesia relate to the limited support policies for renewables and the lack of a level playing field with existing fossil fuel plants. This also reflects the path dependencies related to the coal industry. The current development pipeline for utility-scale renewables is limited, with development being mostly hampered by the complex system of procurement via the single buyer, PLN. Project developers have traditionally needed to conduct lengthy bilateral PPA negotiations and enter into complex joint ventures with PLN. Recognising this challenge, the Ministry of Energy and Mineral Resources introduced a Regulation No.5/2025 in 2025 which outlines new PPA guidelines between renewable energy developers (IPPs) and PLN, creating a standard contractual framework for RE projects (ASEAN Centre for Energy, 2025). If implemented effectively, this could improve project bankability and reduce delays in procurement and PPA negotiations. At the same time, tariffs below the FIT level are often too low and selection criteria for auctions are not transparent. Despite this challenge, Indonesia has announced a strong price signal for battery storage, with the PPA ceiling price for solar plus battery about two-thirds higher than that of solar, indicating the government’s intention to expand storage capacity (Ember, 2025). However, in practice, utilities and developers will still need to negotiate the PPA price, which might be lower than the ceiling price. Futhermore, there is a limited policy framework for direct PPAs (DPPAs), which could hinder corporate RE procurement. When it comes to solar self-consumption, recent policy modifications disadvantage customers by abolishing the net metering system and imposing cumbersome local content requirements. Achieving the ambitious 100GW solar target will require clear policies and a comprehensive implementation framework, such as enshrining the program's targets into a government or Presidential Regulation. With provinces being delegated the authority to plan and allocate budgets for the implementation of the100 GW solar PV program, this presents a policy window to set ambitious energy transition plans at the provincial level. Regarding the planning and permitting regime, the lengthy process for acquiring all the necessary permits for renewable energy projects is seen as a barrier by project developers. Streamlined permitting procedures could help improve project bankability and provide certainty to developers. As far as power system flexibility is concerned, existing “take-or-pay” contracts for fossil fuel plants and the lack of policies for battery procurement and demand-side flexibility could pose a barrier to renewables once the share of wind and solar increases further in the electricity mix. These challenges could be addressed by phasing out take-or-pay contracts and introduce flexibility provisions in remaining contracts to facilitate the integration of renewables. The relatively weak electricity grid infrastructure and lack of interconnections between various islands are another barrier. Substantial financial resources will be required for transmission grid investments, which could be unlocked by adopting third-party business models, such as the Independent Transmission Project (ITP) model and leveraging blended finance instruments. In addition, the absence of regulatory clarity concerning non-discriminatory (third-party) access for generators to the grid is another major barrier to renewable energy investment. Limited public information is provided about grid operation practices and available grid capacity hindering transparency and creating uncertainty for developers. While Indonesia has set long-term decarbonisation objectives as part of its plan to achieve net zero emissions by 2060, the country still lacks a credible strategy for phasing out coal power, while captive coal plants used by industrial parks continue to be built. Adopting ''just transition" policies to cushion the negative effect on coal workers will be crucial once more concrete plans to phase out coal have been defined.
