The Supreme Court in the case of Southern Power Distribution Company Of Andhra Pradesh Limited & Anr. Versus Green Infra Wind Solutions Limited & Ors. has held that Generation-Based Incentive (GBI) is a separate financial entitlement payable to power generators and cannot be adjusted against the tariff determined by State Electricity Regulatory Commissions.
The judgment provides clarity on tariff structuring for renewable energy developers but simultaneously raises a critical and unresolved question under the Goods and Services Tax (GST) framework that whether Incentives Are ‘Consideration for Service’?
The Court observed that GBI is an additional payment made to generators over and above the tariff, aimed at promoting policy objectives such as renewable energy generation and energy transition. It emphasized that such incentives cannot be used by distribution companies (DISCOMs) to reduce the tariff payable under power purchase agreements. This interpretation secures the revenue expectations of developers, particularly in the wind and renewable energy sectors.
However, the judgment’s characterization of GBI as a distinct payment has triggered a deeper tax conundrum. While the supply of electricity is exempt under GST, GBI is not embedded within the tariff and is instead paid separately, typically by the government. This structural separation introduces ambiguity regarding its tax treatment.
Under the Goods and Services Tax regime, the definitions of “supply,” “service,” and “consideration” are notably broad. Tax authorities could potentially argue that activities undertaken by generators—such as setting up renewable energy projects, generating electricity, and feeding it into the grid under government schemes—constitute a service to the government. In such a scenario, GBI may be viewed as consideration for that service, thereby attracting GST.
At the same time, the nature of GBI does not fit neatly into a conventional service contract. The primary supply remains electricity to DISCOMs, which continues to enjoy GST exemption. Moreover, the government is not the direct purchaser of electricity under power purchase agreements. Instead, GBI appears to function more as a policy-driven incentive or grant, subject to compliance with scheme conditions, rather than a quid pro quo arrangement.
This duality creates interpretational uncertainty. On one hand, GBI could be treated as a non-taxable subsidy or grant lacking a direct nexus with any taxable supply. On the other, its linkage to specific performance conditions may invite scrutiny as a taxable consideration.
The stakes are substantial for the power sector, given the scale of incentives involved and the increasing reliance on such schemes to drive renewable capacity. Industry stakeholders are now likely to seek further clarity from policymakers or advance rulings to mitigate potential litigation risks.
The ruling, while settling the tariff question, effectively shifts the spotlight onto GST implications—an issue that could shape the next wave of disputes in the evolving intersection of energy policy and indirect taxation.
