Executive Summary
Energy and infrastructure remain priority sectors for Indonesia. The government continues to push major infrastructure programs, renewable energy development, downstream industrial processing, and energy transition initiatives. Coal remains a major export commodity, but policy is shifting toward natural gas, geothermal, solar, and other renewables.
Legal work in these sectors is complex. Project finance documentation, concession agreements, power purchase agreements, government approvals, environmental permits, land acquisition, construction contracts, and ongoing regulatory compliance all require specialised legal counsel.
This report assesses ten Indonesian law firms on their energy and infrastructure capability.
Indonesia Market Context
Indonesia’s fundamentals are well-documented: a population above 280 million, strong domestic consumption, substantial natural resource wealth, and a manufacturing sector that continues to attract foreign capital. Government priorities include infrastructure, downstream industrial development, digital transformation, and sustained FDI attraction.
Growth has held around 5% despite global headwinds, with foreign investment flowing into manufacturing, energy, mining, infrastructure, financial services, technology, logistics, and consumer goods.
Investors watch regulatory consistency, licensing transparency, and policy implementation closely. These factors keep legal and regulatory counsel particularly valuable.
Rating Methodology
Each firm is scored 1 to 10 per criterion. The weighted average means firm size and brand recognition alone do not drive outcomes.
Rationale for Each Criterion

Firms with project finance expertise provide significant value to sponsors, lenders, and investors. E.g., structuring financing for a renewable energy development involving international lenders.
• Renewable Energy & Energy Transition Expertise (15%) – Indonesia’s evolving energy landscape increasingly emphasises renewable energy and sustainability initiatives. E.g., advising developers on solar, wind, geothermal, or energy transition projects.
• Chambers, Legal 500 & Peer Recognition (10%) – Independent rankings validate market reputation and technical capability within the sector. E.g., Chambers recognition for projects and energy work.
• Quality of Energy Partners & Team (10%) – Major projects often depend on the strategic input and commercial judgment of experienced practitioners. E.g., a partner with extensive experience in project development and financing.
• Government & Regulatory Relationships (10%) – Energy and infrastructure projects require extensive interaction with regulators and government agencies. E.g., advising on approvals involving PLN, ministries, and regulatory authorities.
• Cross-Border Project Experience (10%) – International investors, contractors, and lenders require advisers familiar with global market standards. E.g., coordinating a project involving Indonesian sponsors and foreign financiers.
• Thought Leadership & Market Visibility (5%) – Active participation in industry discussions demonstrates expertise and sector engagement. E.g., publishing commentary on Indonesia’s renewable energy policies.
