CERC's Landmark Decision in PGCIL v. Bihar State Power: Comprehensive Transmission Tariff Determination

Introduction

The case of Power Grid Corporation of India Ltd. (PGCIL) v. Bihar State Power (Holding) Company Ltd. And Others adjudicated by the Central Electricity Regulatory Commission (CERC) on February 4, 2019, marks a significant precedent in the determination of transmission tariffs within India's electricity sector. This case encompasses PGCIL's petition seeking approval for transmission tariffs, capital costs, and various financial adjustments for multiple assets involved in 400 kV transmission line projects in the Eastern Region, specifically at the Biharsharif Sub-station.

Summary of the Judgment

PGCIL filed a comprehensive petition under Regulation-86 of the CERC (Conduct of Business) Regulations, 1999, and Regulation 7 of the CERC (Terms and Conditions of Tariff) Regulations, 2014. The petition sought approval for transmission tariffs from the date of commercial operation (DOCO) up to March 31, 2019, for three key assets involved in 400 kV transmission line projects.

The Commission deliberated on various components, including capital costs, interest during construction (IDC), incidental expenditure during construction (IEDC), initial spares, depreciation, return on equity (RoE), and operation and maintenance (O&M) expenses. A critical aspect of the judgment was addressing delays in project execution caused by external factors such as Right of Way (RoW) issues, excessive rains, and approval delays for railway and power crossings.

After thorough analysis, the CERC approved the transmission tariffs, condoned delays beyond PGCIL's control, and allowed reimbursement of certain expenditures. The decision emphasizes adherence to regulatory frameworks while accommodating unforeseen project impediments.

Analysis

Precedents Cited

The judgment extensively referenced provisions from the CERC (Terms and Conditions of Tariff) Regulations, 2014, specifically Regulations 7, 9, 13, 14, 19, 24, 25, 26, 27, 28, and 29. These regulations outline the framework for capital cost determination, interest calculations, depreciation, additional capital expenditure, and O&M expenses critical to tariff determination.

Additionally, the Commission took cues from prior CERC orders and guidelines that address similar tariff determination cases, ensuring consistency and adherence to established regulatory norms.

Legal Reasoning

The CERC's legal reasoning centered on the meticulous evaluation of PGCIL's claims against the backdrop of the regulatory provisions. Key points include:

Capital Cost Determination: The Commission assessed the capital costs up to DOCO and allowed additional capitalization based on projected expenditures, ensuring alignment with Regulation 9(2).
Delay Condoning: Delays attributable to RoW issues, adjudicated court cases, and approvals were scrutinized. The Commission condoned delays beyond PGCIL's control, particularly those related to RoW problems, while not condoning delays due to excessive rains lacking substantial evidence.
Interest Calculations: IDC and IEDC were calculated in accordance with Regulations 26 and 29, ensuring that only permissible interest and incidental expenditures were included.
Return on Equity (RoE): The judgment applied Regulation 24 and 25 to compute RoE, incorporating the effective tax rate as per Regulation 25.
O&M Expenses: Adherence to Regulation 29 ensured that O&M expenses were calculated based on specified norms.
Additional Capital Expenditure (ACE): Regulation 14(1) was pivotal in allowing ACE based on balance and retention payments within the original scope.

Impact

This judgment sets a robust precedent for the approval of transmission tariffs, emphasizing strict compliance with regulatory frameworks while providing flexibility in unforeseen circumstances. Future cases will likely reference this decision when addressing similar issues related to cost overruns, delays, and tariff adjustments, reinforcing the importance of detailed substantiation in petitions.

Moreover, the clear delineation between condonable and non-condonable delays informs utilities about the expectations and requirements for evidence when seeking adjustments due to project impediments.

Complex Concepts Simplified

1. Right of Way (RoW)

Definition: RoW refers to the legal right to traverse a property for utility installations, such as transmission lines.

In Context: PGCIL faced significant delays due to disputes and legal challenges from landowners, hindering project progress.

2. Interest During Construction (IDC)

Definition: IDC is the interest payable on loans taken to finance the construction phase of a project.

In Context: The Commission evaluated IDC claims to ensure they aligned with actual expenditures and regulatory limits.

3. Return on Equity (RoE)

Definition: RoE represents the profit return earned on shareholders' equity.

In Context: PGCIL's RoE was calculated considering both base rates and tax implications as per CERC regulations.

4. Additional Capital Expenditure (ACE)

Definition: ACE refers to capital costs incurred beyond the original project scope.

In Context: The Commission allowed ACE for projected additional costs within the project’s original scope, subject to regulatory compliance.

5. Operation and Maintenance (O&M) Expenses

Definition: O&M expenses are the costs associated with operating and maintaining transmission systems.

In Context: The O&M expenses claimed by PGCIL were evaluated against predefined norms to ensure they were justified and allowable.

Conclusion

The CERC's decision in PGCIL v. Bihar State Power underscores the Commission's commitment to upholding regulatory standards while accommodating practical challenges faced by transmission operators. By meticulously evaluating PGCIL's claims and aligning them with the CERC's regulatory framework, the Commission has set a clear pathway for transmission tariff determinations.

This judgment not only facilitates financial transparency and accountability but also provides a structured approach for handling project delays and cost overruns. Its comprehensive analysis serves as a guiding framework for future tariff determination cases, ensuring that utility companies adhere to regulatory norms while being fairly compensated for uncontrollable impediments.

In the broader legal context, this decision reinforces the significance of regulatory compliance, detailed substantiation in petitions, and the balanced consideration of utility operational challenges, thereby contributing to a more robust and equitable electricity transmission framework in India.
