Truing Up of Transmission Tariffs and Capital Expenditure: Insights from Power Grid Corporation of India Ltd. v. North Bihar Power Distribution Co. Ltd.
Introduction
The case of Power Grid Corporation of India Ltd. v. North Bihar Power Distribution Company Limited adjudicated by the Central Electricity Regulatory Commission (CERC) on January 7, 2016, centers around the petitioner, Power Grid Corporation of India Ltd. ("Powergrid"), seeking truing-up of its capital expenditure and tariff for specific transmission assets. These assets encompass the 400 kV Teesta (Stage-V) Siliguri transmission line and associated sub-stations in the Eastern Region. Respondents in this matter are primarily distribution and transmission licensees who procure transmission services from Powergrid.
The primary issues addressed in the case involve the accurate adjustment of tariffs based on actual capital expenditures incurred over the periods 2009-2014 under the 2009 Tariff Regulations and 2014-2019 under the 2014 Tariff Regulations. The petitioner contends that the initial tariff orders require revision to reflect the real costs, ensuring fair and just transmission charges for the beneficiaries.
Summary of the Judgment
The Commission meticulously evaluated Powergrid's petition, which asserted the necessity to adjust the tariffs based on actual capital expenditures incurred during the specified periods. The deliberations covered various financial components, including capital costs, additional capital expenditures, debt-equity ratios, interest on loans, return on equity (ROE), depreciation, operation and maintenance (O&M) expenses, and interest on working capital (IWC).
Key decisions included:
- Approval of additional capitalization towards balance and retention payments as per specified regulations.
- Adoption of the actual weighted average rate of interest on loans, aligning with the floating interest rates prevalent during the periods.
- Truing up of ROE based on actual Minimum Alternate Tax (MAT) rates applicable during the tariff periods.
- Adjustment of depreciation and O&M expenses in accordance with the prescribed norms.
- Approval of reimbursement claims for filing fees, publication expenses, license fees, RLDC fees, and deferred tax liabilities.
Ultimately, the Commission upheld Powergrid’s requests for tariff adjustments, ensuring that the transmission charges accurately mirrored the real costs sustained by the petitioner.
Analysis
Precedents Cited
While the judgment primarily focuses on the application of the Central Electricity Regulatory Commission's (CERC) Tariff Regulations of 2009 and 2014, it references prior orders to maintain consistency in tariff determination practices. Notably, the Commission referred to its own previous orders, such as the 2012 order in Petition No. 299/2010 and the 2011 order in Petition No. 238/2010, to guide the truing-up process and interpretation of regulations.
These references underscore the Commission's commitment to a standardized approach in tariff determination, ensuring that each decision builds upon established regulatory frameworks and precedents set in earlier cases.
Legal Reasoning
The Court's legal reasoning is grounded in the meticulous application of specific clauses within the 2009 and 2014 Tariff Regulations. The petitioner’s assertions were evaluated against these regulatory provisions to determine the admissibility and extent of adjustments warranted.
Key aspects of the legal reasoning include:
- Capital Cost Truing Up: The Commission assessed the admissibility of additional capital expenditures under Clause 1(i) and Clause 2(viii) of Regulation 9 of the 2009 Tariff Regulations, ensuring they pertained to balance and retention payments for works executed within the cut-off dates.
- Debt-Equity Ratio: Under Regulation 12 of the 2009 Tariff Regulations, the existing debt-equity ratios were scrutinized and maintained at 70:30, aligning with the opening ratios as on the specified dates.
- Interest on Loan (IOL): The weighted average interest rates were recalculated based on actual loan portfolios and adjusted for any floating rates, adhering to Regulation 16 of the 2009 Tariff Regulations.
- Return on Equity (ROE): ROE was grossed up with the actual MAT rates applicable during the tariff periods as per Regulations 24 and 25 of the 2014 Tariff Regulations, ensuring compliance with tax obligations.
- Depreciation and O&M Expenses: Depreciation was calculated using the Straight Line Method in line with Regulation 17 of the 2009 Tariff Regulations, and O&M expenses were aligned with the norms specified in Regulation 19(g) of the 2009 Tariff Regulations.
- Additional Capital Expenditure: For the 2014-19 tariff period, Regulation 14 of the 2014 Tariff Regulations was applied to admit additional capitalization for existing assets.
Throughout, the Commission emphasized the principle of prudence, ensuring that all claimed expenditures were necessary, within scope, and substantiated by proper documentation such as Auditor's Certificates.

Complex Concepts Simplified
1. Truing Up of Tariffs
Definition: Truing up refers to the adjustment of previously determined tariffs to reflect actual costs incurred, ensuring that service providers are neither under-recovered nor over-recovered.
In Context: Powergrid sought to adjust the transmission tariffs based on the real capital expenditures from 2009-2014 and 2014-2019, moving from estimated to actual costs.
2. Return on Equity (ROE)
Definition: ROE is the rate of return that a company promises to its equity investors. It represents the profitability related to shareholders' equity.
In Context: The Commission adjusted ROE based on the Minimum Alternate Tax (MAT) rates applicable, ensuring that the returns reflected actual tax liabilities.
3. Debt-Equity Ratio
Definition: This ratio indicates the proportion of debt to equity used by a company to finance its assets. A higher ratio suggests more debt financing.
In Context: Powergrid maintained a 70:30 debt-equity ratio, aligning with regulatory requirements, to balance its financing structure.
4. Additional Capitalization
Definition: Refers to any extra capital expenditure beyond the initially planned or approved amounts, often necessitated by unforeseen requirements.
In Context: Powergrid claimed additional capitalization for balance and retention payments post the cut-off date, which the Commission admitted under specific regulatory clauses.
5. Minimum Alternate Tax (MAT)
Definition: MAT is a provision in the Income Tax Act ensuring that certain companies pay a minimum amount of tax based on their book profits, regardless of actual tax liabilities.
In Context: The adjustment of ROE was based on the actual MAT rates applicable, ensuring that returns accounted for mandatory tax payments.
Conclusion
The judgment in Power Grid Corporation of India Ltd. v. North Bihar Power Distribution Co. Ltd. serves as a pivotal reference for the truing up of transmission tariffs, emphasizing adherence to established regulatory frameworks. By meticulously adjusting tariffs based on actual capital expenditures, interest rates, and tax obligations, the Commission ensures a fair balance between service providers and beneficiaries. This decision not only reinforces the principles of transparency and regulatory compliance but also sets a robust precedent for future tariff determination cases within the energy sector. Stakeholders are thereby assured of a structured and equitable approach to financial adjustments, fostering a sustainable and just energy distribution ecosystem.
