| Bank Loan Facilities | 26.90 | IND BBB-/Positive | Affirmed, Outlook Revised |
Operational Performance Highlights
Gamma Green Power demonstrated resilient operational metrics during the trailing twelve months ending February 2026. The company achieved an average net plant load factor of 13.87%, showing improvement from previous periods despite regional wind speed variations.

| Machine Availability | 97.00% | 98.00% | 98.00% |
| Grid Availability | 98.00% | 97.00% | 97.00% |

The company's financial metrics show significant improvement, particularly in interest coverage and debt management. Revenue from operations reached INR250.70 million in 9MFY26, while EBITDA margins expanded substantially to 75.00%.
| Financial Indicator | 9MFY26 | FY25 | FY24 |

Business Profile and Expansion
Gamma Green Power operates 121 wind turbine generators with an aggregate installed capacity of 49.93MW across Tamil Nadu and Gujarat. The company maintains long-term power purchase agreements extending until 2039 with commercial and industrial customers, ensuring stable cash flows. The project portfolio comprises WTGs with capacity ranging from 225KW to 2,000KW.
The company is currently executing an expansion project involving additional wind capacity of 9.90MW in Trichy, Tamil Nadu. As of March 2026, 6.60MW has been commissioned with the balance expected by end-April 2026. The expansion has achieved approximately 90.00% financial progress and is funded through additional debt of INR735.00 million.
Rating Strengths and Constraints
The rating reflects several positive factors including historical generation levels, firm offtake agreements, and comfortable debt service coverage. The presence of long-term PPAs with moderate-to-strong captive consumers and timely payment receipts within 15 days supports the rating.
However, the rating remains constrained by factors such as lower power generation from older equipment, under-construction risks from expansion activities, and inherent wind resource availability risks. The pledging of shares also constrains the rating profile.
Liquidity Position
Gamma Green Power maintains adequate liquidity with INR24.90 million in cash and unencumbered reserves as of February 2026, equivalent to approximately four months of debt servicing obligations. At the group level, Orient Green Power held INR1,725.50 million in cash, bank balance and short-term investments as of September 2025.

How will the completion of the remaining 3.30MW wind capacity expansion by April 2026 impact Orient Green Power's overall financial performance and debt service capabilities?
What are the potential risks to Orient Green Power's revenue stability if their long-term PPAs with commercial and industrial customers face renegotiation pressure before 2039?
Could Orient Green Power leverage this positive rating outlook to secure additional financing for further renewable energy capacity expansion beyond the current 9.90MW project?
