Heldy Satrya Putera of Indonesia’s Investment and Downstreaming Ministry outlined a shift from initial smelting and refining projects toward more advanced manufacturing at the International Critical Minerals and Metals Summit in Bali on September 30. ANTARA reported that phase two prioritizes electric-vehicle batteries, battery energy storage systems and other higher-value manufacturing. The update was not an opening of a factory or an announcement of a new investment agreement with a named company. It described the ministry’s sector priorities alongside investment realization data.

The ministry said realized investment in downstream sectors reached Rp300.1 trillion, or about US$16.86 billion, in January-June 2026. That amounted to 29.7% of total national investment and was 6.9% above the same period a year earlier. The figure is a reported investment realization total; it should not be described as Rp300.1 trillion invested specifically in EV battery projects. The announcement did not break down each subsector’s share or identify the amount of new production capacity associated with the total.

Foreign direct investment accounted for Rp212.8 trillion, or 70.9% of the reported downstream total, while domestic direct investment was Rp87.3 trillion, or 29.1%. Those components sum to Rp300.1 trillion. The foreign share indicates the reported origin of capital, but does not by itself measure development of local suppliers, technology transfer, domestic retention of profits or the quality of jobs created. Assessing those outcomes would require more detailed information by subsector, company, location, project stage and local procurement.

The government’s strategic downstreaming roadmap for 28 core commodities carries an estimated investment requirement of US$618.1 billion through 2040. The Investment Ministry’s overview describes the roadmap as a long-range investment opportunity spanning eight main sectors. This is not committed capital or the cost of a current project portfolio; it is a government estimate of long-term need or potential. It also differs in currency, scope and time horizon from the first-half realization figure. Presenting it as the amount still to be spent after the Rp300.1 trillion would mix unlike measures.

The summit also addressed technical and commercial challenges in the supply chain from nickel to battery materials. ANTARA said discussions covered high-pressure acid leaching, technology integration and the commercial viability of precursor and cathode production. Raw-material availability, technology transfer, product quality, secure offtake and project viability were identified as challenges in moving into later stages. Battery energy storage systems present a related but distinct business: manufacturing cells or packs and integrating storage into the electricity grid involve different assets, permits and customer arrangements.

To assess economic outcomes, future reporting would need to distinguish realized capital from announced budgets and then track capacity, production, exports, local inputs, employment and technology indicators over time. The first-half update reports a substantial share of national investment and annual growth, but the cited announcement does not show how that realization is distributed by sector or region. Batteries and BESS signal a planned evolution of the downstream programme toward more finished products and grid equipment. They do not establish that a complete battery ecosystem is already operating or that US$618.1 billion in financing has been secured.
