Introduction

The case of Power Grid Corporation of India Ltd. v. Madhya Pradesh Power Management Company Ltd. And Others (2021) addresses pivotal aspects of transmission tariff determination under the Central Electricity Regulatory Commission (CERC) Regulations of 2014 and 2019. The petitioner, Power Grid Corporation of India Ltd. (PGCIL), sought truing up of transmission tariffs for the periods 2014-2019 and 2019-2024 concerning specific transmission assets under the WRSS XI Scheme in the Western Region. The respondents included various distribution licensees and power departments primarily benefiting from the transmission services provided by PGCIL.

Summary of the Judgment

The CERC adjudicated PGCIL’s petition for adjusting transmission tariffs based on actual financial metrics and regulatory compliance. Key determinations included:

• Approval of trued-up Annual Fixed Charges (AFC) for both the 2014-2019 and 2019-2024 tariff periods.
• Validation of Additional Capital Expenditure (ACE) claims under specified regulations.
• Rejection of separate Operation & Maintenance (O&M) expenses for PLCC, as per existing regulatory frameworks.
• Deferral of claims related to Security Expenses and Capital Spares to separate petitions.
• Prohibition of recovery of Goods and Services Tax (GST) on transmission charges at the current juncture.

Overall, the court upheld the trued-up tariffs proposed by PGCIL, ensuring alignment with CERC regulations and financial prudence.

Analysis

Precedents Cited

The judgment references prior petitions, notably Petition No. 40/TT/2017 and Petition No. 312/TT/2020, which dealt with similar issues of transmission tariff adjustments and additional capital expenditures. These precedents established the framework for verifying ACE claims and depreciation calculations, ensuring consistency in regulatory decisions.

Legal Reasoning

The court meticulously evaluated PGCIL’s claims against the provisions of the 2014 and 2019 CERC Tariff Regulations. Key aspects of the legal reasoning included:

• Truing Up of Tariffs: Ensuring that the AFC accurately reflects actual costs, including depreciation, interest on loans, RoE, and O&M expenses.
• Defining E-COD: The effective commercial operation date was scrutinized to align tariff calculations accurately.
• ACE Verification: Assessing whether claimed additional capital expenditures were within regulatory allowances and supported by audited financials.
• Rejection of Separate O&M for PLCC: Aligning with previous rulings, the court denied separate O&M expenses for PLCC, treating it as part of the sub-station operations.
• GST and Security Expenses: Recognizing the current non-applicability of GST on transmission charges and deferring security expense claims for separate petitions.

Impact

This judgment reinforces the necessity for transmission licensees to adhere strictly to CERC regulations when claiming AFC adjustments. It clarifies the treatment of specific components like PLCC within O&M expenses and sets a precedent for handling future petitions related to financial adjustments, security expenses, and tax implications. The alignment with prior judgments ensures a consistent regulatory environment, promoting fairness and transparency in tariff determinations.

Complex Concepts Simplified

Truing Up of Transmission Tariffs

Truing up involves adjusting the initially approved tariffs to reflect actual financial metrics over the tariff period. This ensures that transmission service providers recover true costs and do not profit or incur losses due to estimations.

Annual Fixed Charges (AFC)

AFC comprises fixed costs associated with maintaining transmission assets, including depreciation, interest on loans, return on equity (RoE), working capital interest, and O&M expenses.

Additional Capital Expenditure (ACE)

ACE refers to capital expenses incurred beyond the original project scope or after the specified cutoff date. These are subject to strict regulatory approval to prevent unwarranted cost inflations.

Return on Equity (RoE)

RoE represents the return that transmission companies earn on their equity base. It is "grossed up" by the effective tax rate to reflect the pre-tax return necessary to meet financial obligations.

Effective Commercial Operation Date (E-COD)

The E-COD is the date when the transmission assets become operational and start providing services. This date is crucial for calculating depreciation and interest accurately.

Conclusion

The CERC’s decision in the Power Grid Corporation of India Ltd. v. Madhya Pradesh Power Management Company Ltd. case underscores the importance of regulatory compliance and financial accuracy in transmission tariff determinations. By upholding the trued-up AFC and addressing claims methodically, the judgment ensures a balanced approach that safeguards both the transmission provider’s financial health and the beneficiaries’ interests. Additionally, the dismissal of separate O&M requests for PLCC and the handling of GST-related claims provide clear guidance for future tariff petitions, fostering an environment of transparency and accountability within the power transmission sector.
