### **1. PROCEEDINGS & COMMISSION’S DIRECTIONS**

After hearing PGCIL’s representatives, the Commission issued the following procedural directions:

**A. Timeline for Submissions:**
1. **Respondents** (State Utilities) to file their **replies within two weeks**, with an advance copy to PGCIL.
2. **PGCIL** may file its **rejoinder within two weeks** thereafter.

**B. Specific Information Sought from PGCIL (on Affidavit within two weeks):**
The Commission directed PGCIL to provide detailed, asset-specific information for most petitions. The **common themes** across the data requests are:

1. **Detailed Cost Breakdowns:**
* **Item-wise unit cost** for claimed Additional Capital Expenditure (ACE) related to asset replacement.
* **Element-wise/Party-wise break-up** of capital costs (as on 31.3.2019) and claimed ACE.

2. **Historical Comparison & Justification:**
* **Comparison tables** showing ACE **allowed in previous tariff orders vs. claimed now** for 2019-24, with justifications for any variations.
* **Reconciliation of cost overruns** (e.g., Petition 525/TT/2025 notes a variation of ₹1117.53 lakh).

3. **Regulatory Form Compliance:**
* Submission of specific **Forms (e.g., Form-5, 7B, 9C, 9E, 13)** related to plant & machinery cost, depreciation, and tariff calculations for both 2019-24 and 2024-29 periods.

4. **Technical & Economic Justification for Future Capex (2024-29):**
* **Basis, technical justification, and cost-benefit analysis** for ACE/De-capitalization claimed under **Regulation 25(2) of the 2024 Tariff Regulations**.

5. **Supporting Documentation:**
* **Certificates of obsolescence** from OEMs or competent authorities for replaced equipment.
* **Minutes of relevant committee meetings** approving projects (e.g., NERPC/TCC for Kumarghat substation in Petition 539/TT/2025).
* **Liquidated damages recovery statements** and **initial spares discharge statements**.

### **2. KEY BUSINESS & REGULATORY IMPLICATIONS**

* **Regulatory Scrutiny:** The Commission is conducting a **detailed, granular review** of PGCIL’s capital expenditures, both past (truing up) and future (tariff determination). The focus is on **prudence, justification, and cost-effectiveness**.
* **Focus on ACE:** A significant portion of the inquiry revolves around **Additional Capital Expenditure (ACE)**, indicating scrutiny of project cost overruns, replacements, and upgrades.
* **Transparency & Accountability:** The directives emphasize **transparency** through standardized formats (tables, forms), comparisons with past approvals, and demand for third-party certificates (OEM).
* **Procedure:** The process follows a standard regulatory timeline: **Petition → Hearing → Directions for Information → Respondent’s Reply → Rejoinder → Final Order**.
* **Subject Matter:** The petitions cover a wide range of transmission assets—from system strengthening schemes to project-specific systems—highlighting PGCIL’s ongoing role in national grid development and the subsequent periodic tariff resets.
* **Next Steps:** The matters are **reserved for order** after compliance with the above directions. The final tariff orders will determine the revenue PGCIL can recover from beneficiary states for using these transmission assets for the next five years.

### **1. Overview and Context:**
– **Date of Hearing:** 13th January 2026.
– **Common Petitioner:** Power Grid Corporation of India Limited (PGCIL).
– **Subject:** Multiple petitions (listed below) for **truing up of tariffs for the 2019-24 period** and **determination of tariffs for the 2024-29 period** for various transmission assets across India.
– **Regulatory Framework:** Petitions filed under the relevant tariff regulations (e.g., CERC Tariff Regulations, 2019).

### **2. List of Petitions & Key Respondents:**
The petitions involve transmission schemes across different regions. Key respondents are primarily the state power distribution companies (DISCOMs) of the respective beneficiary states.

### **3. Proceedings and Core Issue:**
– PGCIL, as the Central Transmission Utility (CTU), is seeking **regulatory approval for the final tariffs** for its transmission assets.
– The process involves two key steps for each asset:
1. **Truing Up (2019-24):** Final reconciliation of actual capital expenditure (CAPEX) and operational costs against earlier estimates to determine the final payable tariff for the past period.
2. **Tariff Determination (2024-29):** Setting the approved tariff for the next regulatory period based on the trued-up capital cost and normative operational parameters.

### **4. Business & Regulatory Implications:**

– **For PGCIL:** This is a critical, routine regulatory process to **secure revenue recovery** for its vast transmission investments. Timely and accurate submission of the voluminous data is essential to avoid delays in tariff approval and cash flow.
– **For Respondent DISCOMs:** They have the opportunity to **review and challenge** PGCIL’s cost claims. Their scrutiny is vital to ensure that only prudent and efficient costs are passed through to the end consumers via tariffs.
– **For End Consumers:** The outcome of these petitions will ultimately influence the **transmission component of electricity bills** for consumers in the beneficiary states.
– **For the Power Sector:** The process underscores the **regulated, cost-plus nature of transmission tariffs** in India. It ensures transparency and allows recovery of investments for critical national grid infrastructure.
