Background

The Ministry of New and Renewable Energy runs a "Generation Based Incentive" (GBI) scheme that pays wind power generators Rs. 0.50 per unit of electricity fed into the grid, meant to encourage investment in renewable energy separately from whatever tariff a state regulator sets. The Andhra Pradesh Electricity Regulatory Commission (APERC) had factored this GBI into the tariff it fixed for the wind power generator (respondent), effectively reducing what the generator earned from tariff since it was already getting the GBI. The Appellate Tribunal for Electricity (APTEL) disagreed and held the state regulator had no power to touch the GBI at all when fixing tariff. The distribution company (appellant) then approached the Supreme Court, framing the dispute as a stark either/or: either regulators have total control over tariff, or the GBI is completely off-limits to them.

Decision Breakdown

The Supreme Court rejected both extremes. It held that tariff determination remains the exclusive province of the State Electricity Regulatory Commission, and this power is not taken away just because Parliament sanctioned funds for the GBI scheme. However, the Commission's own regulations require it to "take into consideration" any government incentive when fixing tariff, but this does not mean automatically deducting or passing through the GBI amount. Since the GBI was designed as a generator-focused incentive to encourage renewable investment (not a consumer subsidy), the Commission must respect and give effect to that underlying purpose rather than mechanically offsetting it against tariff. The Court dismissed the appeal, holding the GBI is meant to be paid to generators over and above the tariff.

Lesson Learnt

Sectoral regulators have broad, exclusive authority in their domain, but that authority must be exercised purposively and in harmony with the policy objectives behind government incentive schemes: a regulator cannot use its power in a way that defeats the very policy goal (like promoting renewable energy) the incentive was designed to serve.
