In a significant development for India’s renewable energy sector, Trilegal has successfully represented Green Infra Wind Solutions Limited (GIWSL) and Sterling Agro Industries Limited (SAIL) in a landmark ruling by the Supreme Court of India. The case involved a dispute with the Southern Power Distribution Company of Andhra Pradesh Limited (AP Discoms) over the treatment of Generation Based Incentive (GBI) in wind power tariffs.
The issue began when AP Discoms attempted to deduct the GBI, a financial incentive provided by the Ministry of New and Renewable Energy to promote wind energy generation, from the tariff payable to wind power generators. Initially, the Andhra Pradesh Electricity Regulatory Commission (APERC) allowed this deduction. However, the decision was later overturned by the Appellate Tribunal for Electricity (APTEL), leading AP Discoms to challenge the ruling before the Supreme Court.
In its judgment dated March 25, 2026, the Supreme Court upheld the APTEL decision and delivered a clear message on the treatment of renewable energy incentives. The court ruled that GBI is a generator-focused incentive and cannot be treated as a subsidy for consumers or adjusted against tariffs. This ensures that renewable energy developers receive the full benefit of incentives intended to support their projects.
The court also emphasized the role of State Electricity Regulatory Commissions (SERCs), stating that while they have exclusive authority to determine tariffs, they must work in coordination with central agencies and policies. It clarified that regulatory bodies cannot act in isolation or make decisions that undermine national renewable energy goals.
Legal experts involved in the case highlighted the broader impact of the ruling. Vishrov Mukherjee, Partner at Trilegal, noted that the judgment strengthens confidence in India’s renewable energy framework by protecting project economics and ensuring policy clarity. According to him, the decision will help maintain investor trust and encourage further investments in the sector.
The ruling is expected to have far-reaching implications across the energy industry. By preventing distribution companies and state regulators from offsetting central government incentives, the court has ensured that such benefits reach their intended recipients. This will help preserve financial viability for existing renewable energy projects and provide greater certainty for future investments.
Overall, the judgment is seen as a major step forward in supporting India’s clean energy transition. It reinforces the importance of aligning regulatory decisions with national policy objectives and ensures that incentives designed to promote renewable energy are not diluted at the state level.
