The Indonesian state-owned power utility PT PLN has launched the Mentari Nusantara I solar programme, a 1,225 MW tender (PT PLN press release, 01/05/2026). The auction process officially began on 30 April 2026. The solar capacity will be distributed across several regions, including Java (600 MW), Kalimantan (340 MW), eastern regions such as Maluku and Papua (120 MW), West Nusa Tenggara (80 MW), Sulawesi (50 MW), and Sumatra (35 MW). All projects are targeted to reach commercial operation by 2029.
The initiative is being implemented through a new integrated procurement model, “GIGA ONE,” which consolidates multiple projects into a single package. Beyond capacity additions, the programme aims to strengthen domestic industrial capabilities by increasing local content (TKDN) and supporting the development of a national clean energy supply chain.
