Introduction

The case of NHPC Limited v. Central Electricity Regulatory Commission, adjudicated by the Central Electricity Regulatory Commission (CERC) on January 12, 2023, revolves around the determination and adjustment of tariffs for the Dulhasti Hydroelectric Power Station (390 MW). NHPC Limited challenged the CERC's impugned order dated May 9, 2022, seeking revisions in tariff calculations for the periods 2014-2019 and 2019-2024 under the respective Tariff Regulations of 2014 and 2019. The primary issues under contention pertained to the method of grossing up the Return on Equity (ROE) and the treatment of Goods and Services Tax (GST) on security charges.

Summary of the Judgment

The CERC, after reviewing the submissions and examining the relevant regulations, upheld its original calculation of ROE by ruling that the ROE should be grossed up using the Minimum Alternate Tax (MAT) rate, as per Regulation 25(3) of the 2014 Tariff Regulations. This decision countered NHPC Limited's argument that the Effective Tax Rate should have been applied instead. However, recognizing an oversight regarding the impact of GST on security services in Jammu & Kashmir (J&K), the CERC modified the impugned order to allow additional Operational & Maintenance (O&M) expenses related to GST on security services for the period 2017-2019.

Analysis

Precedents Cited

The judgment primarily referenced the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2014, specifically Regulations 24 and 25, which govern the calculation of ROE and the treatment of taxes affecting tariff determination. Additionally, the Statement of Objects and Reasons (SOR) to these regulations was pivotal in elucidating the Commission's stance on the use of MAT versus Effective Tax Rate.

Legal Reasoning

The core of the Commission’s reasoning rested on the explicit provisions of Regulation 25(3), which mandates the gross-up of ROE with the effective tax rate. However, the SOR clarified that in instances where the generating company is subject to MAT, the MAT rate should be utilized for this purpose. NHPC Limited argued for the application of the Effective Tax Rate, claiming a deviation from the regulatory framework. The Commission, however, found that since NHPC was under the MAT regime, its application of the MAT rate was in strict compliance with the regulations and the intent to maintain tax neutrality. As for the GST on security services, the Commission initially overlooked the implementation of GST in J&K for security services, a change in law that was not accounted for in the original O&M expense norms. Recognizing this oversight, the Commission rectified the order to include the GST impact on security services.

Impact

This judgment reinforces the importance of adhering strictly to regulatory provisions when determining tariffs. By upholding the use of the MAT rate for ROE gross-up in applicable cases, the CERC ensures consistency and compliance with established tariff regulations. Moreover, the modification concerning GST on security services underscores the Commission's willingness to address and rectify genuine oversights, ensuring that tariff determinations remain fair and reflective of actual operational costs. Future cases involving tariff determinations will likely reference this judgment to justify the application of MAT or Effective Tax Rates based on the regulatory context.

Complex Concepts Simplified

Return on Equity (ROE)

ROE is the rate of return that equity investors expect on their investment in a company. In the context of electricity tariffs, it represents the earnings generated from the equity base of the generating station.

Minimum Alternate Tax (MAT)

MAT is a tax provision that ensures companies pay a minimum amount of tax, regardless of their profitability. It applies to companies that may otherwise reduce their tax liability through various deductions and exemptions.

Effective Tax Rate

Effective Tax Rate refers to the average rate at which a company's pre-tax profits are taxed. It considers all tax liabilities, including corporate tax, surcharges, and cess.

Goods and Services Tax (GST) on Security Services

GST is a comprehensive indirect tax levied on the supply of goods and services. The imposition of GST on security services in J&K necessitated adjustments in O&M expenses for entities like NHPC Limited that procure such services.

Conclusion

The CERC's judgment in the NHPC Limited case underscores the criticality of adhering to regulatory frameworks in tariff determination. By upholding the application of the MAT rate for ROE gross-up where applicable, the Commission reinforces regulatory compliance and tax neutrality principles. Simultaneously, the rectification regarding GST on security services exemplifies the Commission's commitment to accurate and fair tariff assessments. This dual outcome not only preserves the integrity of tariff regulations but also ensures that generating companies operate within a well-defined and equitable financial structure.
