Indonesia Tenders 1.2 GW of Solar

Why It Matters

By aggregating multiple sites, the Giga One tender accelerates Indonesia’s renewable rollout and signals confidence to global investors, crucial for meeting the country’s 100 GW solar target and reducing reliance on fossil fuels.

Key Takeaways

• PLN launches 1.225 GW solar tender across six Indonesian regions
• Giga One scheme bundles projects for economies of scale
• Targeted commercial operation date set for 2029
• Supports Indonesia’s goal of 100 GW solar capacity by 2030
• Blueprint to be reused for wind, hydro, storage tenders

Pulse Analysis

Indonesia has set an ambitious target of 100 GW of solar power by the early 2030s, a mix of 80 GW decentralized rooftop systems and 20 GW large‑scale farms. After surpassing 1 GW of installed capacity in 2023, the country is now scaling up with the Mentari Nusantara I tender, which aggregates 1,225 MW across Sumatra, Kalimantan, Java, Sulawesi, West Nusa Tenggara and the Maluku‑Papua region. The geographic spread not only diversifies generation but also brings electricity to remote islands that have historically relied on diesel generators.

The tender is run through PLN’s ‘Giga One’ integrated procurement scheme, a novel approach that bundles several projects into a single package. By offering a unified contract, Giga One reduces transaction costs, streamlines permitting and provides investors with a clearer revenue timeline, thereby lowering financing premiums. PLN officials say the model will be replicated for upcoming wind, hydro and battery storage auctions, creating a standardized pathway for renewable development and signaling a maturing market that can attract larger, institutional capital.

From an investor perspective, the 2029 commercial operation target and the scale of the bundle make the deal comparable to utility‑scale projects in Southeast Asia’s more mature markets. The tender is expected to draw interest from global EPCs and financiers eager to tap Indonesia’s growing demand for clean energy, especially as the nation phases out coal and seeks to meet its climate commitments under the Paris Agreement. Successful execution could also spur regional job creation and stimulate local supply chains, reinforcing Indonesia’s position as the next major renewable hub in the Indo‑Pacific.
