Indonesia has officially launched its ambitious “100GW Solar Archipelago Plan”, a landmark initiative to drive national energy transition and energy security. The roadmap outlines a total target of 100GW solar capacity by 2060, split into 80GW of decentralized solar systems (deployed across 80,000 villages) and 20GW of centralized solar farms, paired with a supporting 320GWh battery energy storage system (BESS) capacity.
The first phase of the project requires an estimated $78 billion in investment, with a focus on replacing diesel power plants in remote islands and rural areas. The Indonesian government has mandated that all new renewable energy projects must include 15%-20% energy storage capacity starting in 2026, creating a 10.3GW immediate demand for electrochemical energy storage solutions. This policy not only accelerates the deployment of grid-scale storage but also drives the penetration of residential solar storage systems, as households seek to reduce reliance on unstable grid power and high electricity costs.
As a key part of the plan, the government is also accelerating the development of domestic battery manufacturing, with a $1.4 billion investment led by sovereign wealth fund Danantara to build a 50GW solar module factory and supporting 320GWh storage production capacity. This initiative positions Indonesia as a regional hub for renewable energy and energy storage, creating unprecedented opportunities for global storage solution providers.
