Tariff regulation and government incentives: regulator may consider subsidies, but must apply them purposively and consistently.

Tariff determination under the Electricity Act, 2003 remains within the exclusive jurisdiction of the State Electricity Regulatory Commission, and Regulation 20 requires it to consider any government incentive or subsidy availed by the generating company. The existence of a Generation Based Incentive does not oust that jurisdiction; instead, the Commission must apply the incentive consistently with the statutory framework and the policy of promoting renewable generation, affordability, and consumer protection. The incentive cannot be treated as an automatic consumer-side deduction if that would defeat its purpose. The tariff regulator's authority was affirmed, but the treatment that would have transferred the benefit away from the generator was rejected.

Issues: (i) Whether the State Electricity Regulatory Commission has the power and jurisdiction to consider and factor in a Generation Based Incentive while determining tariff; (ii) what duties and obligations govern tariff determination when the Commission exercises that exclusive jurisdiction.

Issue (i): Whether the State Electricity Regulatory Commission has the power and jurisdiction to consider and factor in a Generation Based Incentive while determining tariff.

Analysis: Tariff determination is the exclusive province of the Electricity Regulatory Commissions under the Electricity Act, 2003, and there is no unallocated regulatory residue outside that field. Regulation 20 of the 2015 Tariff Regulations expressly requires the Commission to take into consideration any incentive or subsidy offered by the Central or State Government if availed by the generating company. The existence of a Union grant does not exclude the statutory power of the Commission; it only means that the Commission must consider the incentive in accordance with the governing statutory framework and regulations.

Conclusion: The Commission has the power and jurisdiction to consider and factor in the Generation Based Incentive while determining tariff.

Issue (ii): What duties and obligations govern tariff determination when the Commission exercises that exclusive jurisdiction.

Analysis: The Commission must exercise its tariff power holistically and in harmony with the statutory policy of promoting renewable energy, protecting consumer interests, and ensuring affordability and sustainability. A subsidy or incentive designed to support generators cannot be treated mechanically as a consumer-side deduction merely because tariff fixation lies with the regulator. The incentive must be given contextual and purposive effect so that the policy objective behind the grant is not defeated. Regulatory power must operate as a collaborative enterprise and not in a manner that nullifies the purpose of the policy or grant.

Conclusion: The Commission is obliged to treat the incentive purposively and consistently with the object of promoting renewable generation, rather than by automatic or mechanical deduction.

Final Conclusion: The appeal fails, and the tariff regulator's authority is affirmed, but the impugned treatment of the incentive is rejected because the benefit was intended to remain with the generating company over and above tariff.

Ratio Decidendi: A tariff regulator may consider a government incentive or subsidy only in a manner that is consistent with the statutory scheme and the purpose of the incentive, and the existence of a government grant does not by itself oust the regulator's tariff jurisdiction.
