Indonesia has launched the 1.2 GW Mentari Nusantara solar tender, creating a major new opportunity for utility-scale solar development and clean energy investment.

The tender is designed to accelerate renewable power deployment while supporting the country’s wider energy transition goals. Large solar procurement can help diversify Indonesia’s power mix and reduce dependence on fossil fuel generation over time.

For developers and investors, the program signals stronger policy momentum around solar energy and offers a pathway for new capacity additions across suitable project locations.

The initiative also reflects growing regional interest in competitive renewable energy procurement, where transparent tenders can help lower costs and attract experienced project sponsors.

As Indonesia works to expand clean electricity supply, the Mentari Nusantara tender could become an important milestone for scaling solar power and strengthening long-term energy security.
