Indonesia is pursuing broad infrastructure expansion in transport, energy, power grids and urban services to support its goal of becoming a high-income economy by 2045. Major reforms and blended finance packages backed by institutions like the World Bank seek to strengthen electricity networks, expand access to clean energy and enhance financial and digital infrastructure. The government is also promoting private sector participation through public–private partnerships, streamlined project facilitation and innovative financing mechanisms to bridge a large funding gap. Despite strong long-term growth prospects, geographic dispersion, financing constraints and regulatory complexity remain challenges to realising the full potential of infrastructure investment.
