Introduction

The case of National Thermal Power Corporation Ltd. v. Uttar Pradesh Power Corporation Ltd. adjudicated by the Central Electricity Regulatory Commission (CERC) on July 1, 2004, marks a significant precedent in the realm of power tariff regulation in India. This dispute primarily revolved around the determination of tariffs for two power stations operated by the petitioner, National Thermal Power Corporation Ltd. (NTPC): the Feroze Gandhi Unchahar Thermal Power Station (FGUTPS) and Dadri Gas Power Station (Dadri GPS).

The petitioner challenged the tariff orders issued by CERC, raising concerns over various aspects such as the calculation of maintenance spares, interest on working capital loans, inclusion of incentive payments in Operation & Maintenance (O&M) expenses, and errors in professional charges. The Commission's decision to dismiss the review petitions has set a notable benchmark for future tariff determinations and regulatory compliance.

Summary of the Judgment

NTPC filed Review Petitions Nos. 103/2003 and 104/2003 challenging CERC's tariff orders dated October 24, 2003, for FGUTPS and Dadri GPS respectively, covering the period from April 1, 2001, to March 31, 2004. The petitioner raised four main issues:

• Calculation basis for maintenance spares in working capital.
• Methodology for computing interest on working capital loans.
• Exclusion of incentive and ex-gratia payments in O&M expenses.
• Errors in the computation of professional charges.

After thorough examination, CERC dismissed all the review petitions, reaffirming its original tariff determination methodologies. The Commission maintained that the petitioner could not retrospectively apply new regulations or deviate from established principles, thereby upholding the integrity and consistency of its regulatory framework.

Analysis

Precedents Cited

In addressing the petitioner's challenges, CERC referred to several of its previous orders, notably:

• Order dated March 8, 2004 (Review Petition No. 74/2003): Rejected similar objections regarding maintenance spares.
• Order dated May 2, 2003 (Review Petition No. 126/2002): Affirmed the principle of computing interest on loans using the "whichever is higher" methodology.

These precedents underscored CERC's commitment to consistency in tariff determinations and its resistance to ad hoc revisions based on subsequent regulatory changes or petitioner's arguments.

Legal Reasoning

1. Quantum of Spares

CERC adhered to the terms specified in the Central Electricity Regulatory Commission (Terms & Conditions of Tariff) Regulations, 2001. It maintained that maintenance spares should be calculated as 1% of the capital cost as of April 1, 2001, rather than on an average over five years. The Commission emphasized that retrospective application of updated regulations (from March 29, 2004) was not permissible.

2. Interest on Working Capital

The Commission defended its approach of calculating interest based on the higher of actual or normative loan repayment. CERC highlighted that altering this principle would disrupt established methodologies and disadvantage not only NTPC but potentially other generating companies, ensuring fairness and uniformity across the sector.

3. Incentive and Ex-Gratia Payments in O&M Expenses

CERC differentiated between statutory bonuses and productivity-linked incentives. It reasoned that incentive and ex-gratia payments, being performance-based and not obligatory under the Payment of Bonus Act, should not be included in O&M expenses. This policy aligns with the Commission's objective to safeguard consumer interests by ensuring that additional productivity gains are not passed on as operational costs.

4. Professional Charges

Addressing the alleged errors in professional charges, CERC conducted a re-verification and identified only typographical mistakes in the computation table, which did not affect the overall O&M expenses. Consequently, it deemed the petitioner's objections on this point unwarranted.

Impact

This judgment reinforces several critical aspects of tariff regulation:

• Regulatory Consistency: Emphasizes the importance of adhering to established methodologies and resisting retroactive adjustments.
• Clarity in Expense Classification: Distinguishes between mandatory and performance-based costs, setting a clear precedent for future O&M expense calculations.
• Precedent on Review Petitions: Strengthens the Commission’s stance on the non-admittance of review petitions that challenge settled principles or attempt to alter them based on subsequent regulatory changes.

Future cases involving tariff disputes can refer to this judgment for guidance on the parameters of acceptable review grounds and the boundaries of regulatory flexibility.

Complex Concepts Simplified

1. Maintenance Spares

Maintenance Spares refer to spare parts necessary for the upkeep and repair of power station equipment. Proper calculation of maintenance spares ensures that operational disruptions are minimized, maintaining consistent power generation.

2. Working Capital

Working Capital is the capital required for the day-to-day operations of a business. In this context, it includes funds needed for maintenance spares and interest on loans taken to finance these operational aspects.

3. Operation & Maintenance (O&M) Expenses

O&M Expenses encompass all costs associated with running and maintaining a power station. This includes employee salaries, maintenance costs, utility charges, and other operational expenditures.

4. Interest on Working Capital Loans

This refers to the interest payable on funds borrowed to finance the working capital. The methodology for calculating this interest can significantly impact the overall tariff structure.

5. Incentive and Ex-Gratia Payments

Incentive Payments are additional remunerations based on performance metrics, while Ex-Gratia Payments are discretionary payments made to employees beyond their contractual obligations.

6. Professional Charges

These are fees paid for professional services such as consultancy, auditing, and legal advice, essential for the effective management and operation of the power stations.

Conclusion

The judgment in National Thermal Power Corporation Ltd. v. Uttar Pradesh Power Corporation Ltd. underscores CERC's unwavering commitment to regulatory consistency and consumer protection in tariff determinations. By dismissing the review petitions on grounds that attempted to alter established methodologies or retroactively apply new regulations, the Commission reinforced the importance of adherence to defined regulatory frameworks.

Additionally, the clear demarcation between mandatory statutory expenses and performance-based incentives sets a robust framework for future O&M expense computations, ensuring that tariff structures remain transparent, fair, and reflective of actual operational costs. This decision serves as a pivotal reference point for stakeholders in the power sector, guiding them in tariff negotiations and regulatory compliance.

Ultimately, this judgment not only resolves the immediate disputes between NTPC and Uttar Pradesh Power Corporation Ltd. but also fortifies the foundational principles governing tariff determinations, thereby contributing to a more stable and predictable regulatory environment in India's power sector.
