In 50 words: Indian green bond issuance for renewable energy projects crossed $8 billion in calendar 2025, growing 45% year-over-year. ReNew, Adani Green, JSW Energy, and ACME Solar lead issuance. Coupon rates have compressed 50–80 basis points relative to vanilla corporate bonds — green premium is now real and consistent.
The numbers
Indian green bond issuance for renewable energy:
- 2022: $2.8 billion
- 2023: $4.2 billion
- 2024: $5.5 billion
- 2025: $8.0 billion
- Q1 2026: $2.3 billion (annualised: ~$9.0 billion)
Top issuers (2024–2025)
By cumulative issuance:
- ReNew Energy Global: $1.8 billion
- Adani Green Energy: $1.4 billion
- JSW Energy: $0.9 billion
- ACME Solar: $0.6 billion
- Greenko: $0.5 billion
- Azure Power: $0.4 billion
- Renew Power Finance: $0.3 billion
- Tata Power Renewable Energy: $0.3 billion
The green premium
Green bonds have priced at lower coupon rates than equivalent vanilla bonds:
- Investment grade renewable issuers: 50–80 bps green premium
- Below-investment-grade issuers: 30–60 bps green premium (smaller but consistent)
The premium has been consistent enough that ESG-mandated buyers (sovereign wealth funds, pension funds with green mandates) reliably absorb supply.
What's driving demand
- ESG-mandated institutional capital expansion globally
- Sovereign wealth fund green allocation requirements
- Banking sector green portfolio requirements (some Indian banks)
- Insurance company climate risk capital requirements (EU especially)
What's driving supply
- Renewable project capex requires multi-trillion-rupee long-term capital
- Refinancing of operational assets at lower cost
- Strategic decarbonisation announcements requiring visible green capital deployment
- Compliance with offshore listing requirements
Standards and certification
Indian green bond issuance follows:
- SEBI green bond framework (mandatory for Indian listing)
- ICMA Green Bond Principles (international standards)
- Climate Bonds Initiative certification (optional, more demanding)
- Some issuers also pursue Climate-Aligned Bond labels
What's not yet green-bond-financed
- Most BESS standalone projects (still using vanilla project finance)
- Green hydrogen at scale (early stage)
- Most C&I behind-the-meter solar
These categories should expand into green bond financing through 2027 as project scales support bond-grade issuance volumes.
What to watch next
The expected $10 billion+ Adani Green refinancing in late 2026 will test whether the green premium holds for very large single-issuer transactions. Outcome will shape 2027 issuance pricing across the sector.
