### 1. Overview of the Hearing

This document is a “Record of Proceedings” from a CERC hearing involving multiple tariff petitions filed by PGCIL. The primary purpose of these petitions is twofold:

1. **Truing-up (2019-24):** Adjusting the provisional tariff approved for the previous control period based on actual capital expenditure and performance.
2. **Tariff Determination (2024-29):** Setting the transmission tariff for the upcoming control period.

The hearing involved petitions for transmission assets across the Northern, Eastern, North-Eastern, and Western Regions of India, as well as the India-Bangladesh interconnection.

### 2. Key Business & Regulatory Directives

The Commission did not approve the tariffs during this hearing. Instead, it issued specific directions to PGCIL to submit additional data. The approval of tariffs is contingent upon the submission of this information.

#### A. General Directives for All Petitions
– **Respondent Filings:** All Respondents (State Power Utilities like UPPCL, MPPMCL, BSPHCL, etc.) were directed to file their replies, if any, within **one week**.
– **Rejoinder:** PGCIL was granted one week thereafter to file its rejoinder to those replies.

#### B. Specific Information Requirements (Business Impact)

PGCIL must provide the following data on affidavit. These requirements highlight the level of detail regulators require to justify tariff hikes.

**For Petition No. 602/TT/2025 (Tehri Transmission System – Northern Region):**
– **Form 9C (Excel):** A detailed statement of tariff calculations. This is the core financial model for the asset.
– **Cumulative Depreciation:** Item-wise depreciation details up to 31 March 2019. This affects the calculation of the remaining value of the asset.
– **Liability Flow Statement:** A reconciliation of liabilities with the Additional Capital Expenditure (ACE) claimed. This ensures that debt claimed is actually deployed.
– **Land Payment Proofs:** Proofs of payments made to landowners. This is critical for validating project costs.
– **Equipment Replacement Details:** A table justifying the cost of replacing equipment (see format below).

**For Petition No. 18/TT/2025 (India-Bangladesh Interconnection – Eastern Region):**
– **Appeal Update:** PGCIL must provide an update on **Appeal No. 92/2022** pending before APTEL (Appellate Tribunal for Electricity). The outcome of this appeal could impact the tariff.
– *(Other requirements similar to above: Liability Flow Statement, Form 9C, Cumulative Depreciation).*

**For Petition No. 822/TT/2025 (Eastern Region Strengthening Scheme):**
– **Form 7B & 9C:** Submission of these specific financial forms.
– **Item-wise ACE:** Details of Additional Capital Expenditure for both the 2019-24 and 2024-29 periods.
– **Equipment Replacement Details:** See format below.

**For Petition No. 750/TT/2025 (Rewa Ultra Mega Solar Park – Western Region):**
– The Respondent (MPPMCL) was specifically granted time to file its reply, indicating possible contention regarding the tariff for evacuating power from this major solar park.

### 3. Data Format Requirement

For Petitions involving equipment replacement (e.g., Nos. 602, 822), CERC mandated the following data format to justify the capital expenditure:

| Particulars of Equipment | Station | Location | Qty | COD | Per Unit Cost | Total Estimation Cost | ACE claimed (F.Y. wise) |
| :— | :— | :— | :— | :— | :— | :— | :— |

– **Business Relevance:** This level of detail ensures that utilities (and ultimately consumers) are not charged for inefficient or unnecessary replacement of assets.
