Reaffirmation and Clarification of Transmission Tariff Components under CERC Regulations: Power Grid Corporation v. Madhya Pradesh Power Trading Company
Introduction
The case of Power Grid Corporation Of India Ltd. v. Madhya Pradesh Power Trading Company Ltd. adjudicated by the Central Electricity Regulatory Commission (CERC) on December 30, 2011, marks a significant development in the determination of transmission tariffs in India. This case revolves around Power Grid Corporation of India Limited (PGCIL) seeking approval for determining the transmission tariff for the 220 kV D/C Vapi-Khadoli transmission line within the Western Region's WRSS-V transmission system. The primary issues addressed include the approval of various cost components such as depreciation, interest on loans, return on equity, interest on working capital, and operation & maintenance (O&M) expenses, in line with the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2009.
Summary of the Judgment
CERC reviewed PGCIL's petition for transmission tariff approval covering the period from October 1, 2010, to March 31, 2014. PGCIL claimed various charges amounting to a total transmission cost ranging from ₹329.98 lakhs in 2010-2011 to ₹715.33 lakhs in 2013-2014. Respondent Maharashtra State Electricity Distribution Co. Ltd. (MSEDCL) raised objections concerning additional expenditures, reimbursement claims, service tax, and license fees. CERC meticulously examined each contention, applying relevant regulations to either approve, restrict, or reject specific cost claims. Key outcomes include the restriction of additional capital expenditure, approval of certain reimbursement claims, and clarification on the treatment of license fees and service tax. The final transmission charges were computed based on regulated norms, ensuring compliance with CERC's 2009 regulations.
Analysis
Precedents Cited
While the judgment primarily relied on the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2009, it referenced previous orders and interpretations, such as the Commission's order dated September 11, 2008, in Petition No. 129/2005, and the order dated January 11, 2010, in Petition No. 109/2009. These precedents provided a framework for evaluating claims related to additional expenditures, reimbursement of petition filing fees, and service taxes, ensuring consistency in tariff determination across different cases.
Legal Reasoning
CERC's legal reasoning was rooted in a meticulous application of the 2009 regulations. For instance:
- Capital Cost: CERC scrutinized PGCIL's claimed capital costs against Regulation 7(1)(a), permitting only sanctioned expenditures up to the apportioned approved cost.
- Cost Overrun: The Commission allowed certain compensations related to tree and crop compensation but restricted the overall cost to the approved estimates pending revised cost submissions.
- Treatment of Initial Spares: Excess claims for initial spares were adjusted in accordance with Regulation 8, ensuring that only permissible amounts were included in tariff calculations.
- Debt-Equity Ratio and Return on Equity: Regulations 12 and 15 guided the determination of normative loans and ROE calculations, ensuring adherence to prescribed financial structures.
- Interest on Loan and Working Capital: Regulation 16 governed the computation of interest on loans, while Regulation 18 delineated the components and interest rates applicable to working capital, ensuring standardized financial treatment across transmission projects.
This grounded approach ensured that tariff determinations were both fair and consistent with regulatory standards.
Impact
This judgment has far-reaching implications for future transmission tariff determinations by CERC. By providing clear guidelines on the approval and restriction of various cost components, CERC ensures greater transparency and accountability in tariff setting. The strict adherence to the 2009 regulations, especially concerning capital expenditure and reimbursement claims, sets a precedent that beneficiaries and transmission licensees must follow, thereby fostering a more regulated and predictable tariff environment. Additionally, clarifications on handling license fees and service taxes provide a clearer framework for future petitions, reducing ambiguities and potential disputes.
Complex Concepts Simplified
1. Transmission Tariff
Transmission tariff refers to the charges levied for the transportation of electricity from generation points to distribution networks. It encompasses various cost components incurred by the transmission utility.
2. Additional Capital Expenditure
These are expenses incurred over and above the initially sanctioned capital costs for a project. CERC regulates the acceptance of such expenditures to prevent unwarranted cost inflations.
3. Normative Loan
A normative loan is an estimated or standard amount borrowed to finance a project, as determined by regulatory guidelines, regardless of the actual loan taken.
4. Return on Equity (ROE)
ROE is the profit generated on the equity invested by the shareholders. In this context, it represents the financial return the transmission company earns on its capital base.
5. Interest on Working Capital
This is the interest charged on the funds required to manage the daily operations of the transmission system, such as maintenance supplies and operational expenses.
Conclusion
The CERC's decision in Power Grid Corporation Of India Ltd. v. Madhya Pradesh Power Trading Company Ltd. serves as a comprehensive reaffirmation of the 2009 tariff regulations, offering detailed guidance on various cost components involved in transmission tariff determination. By meticulously evaluating each claim against established regulations, CERC has reinforced the principles of fairness, transparency, and regulatory compliance in the electricity transmission sector. This judgment not only clarifies existing ambiguities but also sets a robust framework for future tariff assessments, ensuring that transmission charges remain equitable for both service providers and beneficiaries.
