Does an obligation to take into consideration an incentive or subsidy while determining tariff require the Regulatory Commission to deduct that incentive from the tariff?

Answer

No. The need to take into account does not mechanically translate into either a mandatory deduction or automatic pass-through; it requires a contextual and purposive treatment, and factoring in the incentive cannot be divorced from its underlying objective. Where a scheme was intended not as a consumer subsidy but as a generator-focused incentive integrally linked to realization of national and international policies, the Commission must respect and give effect to it.

Headnote

Electricity Act, 2003 — ss.61, 64(6) and 86 — Tariff determination — Generation Based Incentive — Regulation 20, APERC (Terms and Conditions for Tariff Determination for Wind Power Projects) Regulations, 2015 — Constitution of India, Arts. 282 and 114(2) — Regulatory autonomy — Collaborative enterprise — Electricity Act, 2003 — ss.61 and 86 — Exclusive province of the Regulatory Commission — Incentive or subsidy — Held: There is no unallocated regulatory residue left outside the Electricity Regulatory Commissions' jurisdiction, tariff determination being their exclusive province. The direction that the Commission "shall take into consideration any incentive or subsidy offered by the Central or State Government" denotes a statutory obligation to consider its bearing on tariff, and that power is not excluded by the mere existence of a Union grant. (¶21, 22, 28) Constitution of India — Arts. 282 and 114(2) — Destination of a Parliamentary grant — Held further: The grant reached its destination when it was released in favour of the wind GENCOs, and there has been no diversion, much less subversion, of the sums allocated. The beneficiary remains the GENCO; the Commission does not intercept or redirect the payment, it merely determines the tariff payable by the DISCOM to the GENCO. (¶26, 27) Electricity Act, 2003 — Regulatory power as a collaborative enterprise — Contextual and purposive treatment — Held further: The need to "take into account" does not mechanically translate into either a mandatory deduction or automatic pass-through, but requires a contextual and purposive treatment. Regulatory authority cannot be exercised in a manner that nullifies the legislative or policy intent or the intent of the grant; the appeal was dismissed. (¶43, 46, 47)

In the Court's own words
Paragraph 43Hence, it is restated that the Parliamentary allocation and grant of generator incentive does not ipso facto exclude the regulatory mechanism, nor does it denude the Regulatory Commission of its tariff determination power. However, while we hold that the Commission has the last word in determination of tariff, we are in disagreement with its treatment of the GBI while determining tariff in the present case. Regulatory authority cannot be exercised in a manner that nullifies the legislative or policy intent or the intent of the grant, just because power and jurisdiction to determine tariff is exclusively vested in the Regulatory Commission. Under Regulation 20, while determining tariff the Regulatory Commission, “shall take into consideration any incentive or subsidy offered by the central or state government”. However, the need to “take into account” does not mechanically translate into either a mandatory deduction or automatic pass-through. It requires a contextual and purposive treatment. Factoring in the incentive into tariff cannot be divorced from its underlying objective. The importance of the policy to encourage investment in renewable energy sources has already been explained. If a scheme was not intended as a “consumer subsidy”, but as a “generator-focused incentive” and the scheme is integrally linked to realization of national and international policies, the Commission must respect and give effect to it.

Can a State Electricity Regulatory Commission, while exercising its power to determine tariff under the Electricity Act, 2003, consider and factor in a Generation Based Incentive granted by the Union Government?Does factoring a Parliamentary grant into tariff amount to varying the amount or altering the destination of that grant contrary to Article 114(2) of the Constitution of India?
