Summary:

—-

**1. Document Nature & Core Issue:**
* This is a **regulatory proceeding record** from the **Central Electricity Regulatory Commission (CERC)**.
* **Petition No.:** 820/TT/2025.
* **Petitioner:** Rajasthan Rajya Vidyut Prasaran Nigam Limited (RRVPN) – the state transmission utility of Rajasthan.
* **Core Business Issue:** Determination of the **transmission tariff** for specific RRVPN-owned transmission lines for the five-year period from **2024-25 to 2028-29**, and their **inclusion in the Point of Connection (POC) transmission charges** pool.

**2. Asset Under Scrutiny & Regulatory Context:**
* **Assets:** RRVPN-owned transmission lines/systems that:
1. Connect Rajasthan with other states.
2. Are “intervening transmission lines incidental to inter-State transmission of electricity.”
* **Key Regulatory Question:** The petition seeks to classify these lines as part of the **Inter-State Transmission System (ISTS)**, thereby allowing RRVPN to recover their tariff through the national POC charge mechanism, which is shared by all beneficiaries across the grid.

**3. Current Status & Commission’s Directive:**
* A virtual hearing was held on **20th January 2026**.
* The Commission has **initiated the formal adjudication process** and issued procedural and substantive directives.
* The next hearing is scheduled for **16th April 2026**.

**4. Commission’s Directives & Required Actions:**

**A. Procedural Directives (Parties & Timeline):**
1. **Add Key Parties:** RRVPN must implead **NRPC (Northern Regional Power Committee), NRLDC (Northern Regional Load Despatch Centre), and CTUIL (Central Transmission Utility of India Ltd)** as respondents within **2 weeks**. This ensures all relevant grid planning and operational authorities are formally involved.
2. **Notice & Replies:** Notices to be issued to all respondents, who must file their replies within **4 weeks**. RRVPN can then file a rejoinder within **2 weeks** after that.

**B. Substantive Information Requests (To be filed by RRVPN within 4 weeks):**
The Commission’s queries are focused on establishing the **functional necessity and operational character** of the lines as ISTS assets. RRVPN must provide:
1. **Purpose of Construction:** Justify the fundamental need for building these lines.
2. **Regular ISTS Use:** Clarify if the lines are **regularly used for evacuating and transferring ISTS power** (as opposed to intra-state power).
3. **Power Flow Details:** Provide projected/actual power flow data for the 2024-29 period to demonstrate inter-state power transfer volumes.
4. **Availability Data:** Submit line availability details, a key performance metric for tariff determination.
5. **Critical Evidence – SLDC Certification:** Provide **supporting documents from the State Load Despatch Centre (SLDC)** certifying that **3 specific non-ISTS lines** are carrying **more than 50% ISTS power**. This is a crucial regulatory threshold for re-categorization.
6. **Single Line Diagram:** Submit a technical diagram of the petitioned lines, essential for understanding their role in the grid.
