Summary:

—-

#### 1. Subject Matter of the Petition
The petition seeks the **determination of transmission tariff** for certain intra-State transmission lines owned by **APTRANSCO** (Transmission Corporation of Andhra Pradesh Limited). The key aspects are:

– **Assets in Question:** Intra-State transmission lines owned by APTRANSCO.
– **Purpose:** These lines facilitated the flow of **inter-State power** during the period from **November 1, 2020, to March 31, 2021**.
– **Tariff Mechanism:** The tariff determination is sought for **inclusion in the POC (Point of Connection) Mechanism**. The POC mechanism is a CERC-administered framework that determines transmission charges for inter-State and inter-regional power flow, ensuring cost recovery for transmission infrastructure used for such flows.

#### 2. Parties Involved
| Party | Role |
|——-|——|
| **APTRANSCO** (Transmission Corporation of Andhra Pradesh Limited) | **Petitioner** – Seeking tariff determination for its assets. |
| **TANTRANSCO** (Transmission Corporation of Telangana Limited) & 7 Others | **Respondents** – Other entities likely impacted by or party to the transmission arrangements. |

#### 3. Summary of Proceedings (Hearing dated March 19, 2026)
The matter was heard virtually. Key developments:

– **Petitioner’s Request:** The counsel for APTRANSCO sought additional time to comply with directions issued by the Commission in the Record of Proceedings (RoP) from the previous hearing dated December 19, 2025. A request for adjournment was made.
– **Respondents’ Status:** None of the respondents appeared, and no replies have been filed despite prior notice from the Commission.

#### 4. Commission’s Directions
The CERC issued the following directions:

| Direction | Details | Timeline |
|———–|———|———-|
| **To Petitioner (APTRANSCO)** | Submit the information called for in the December 19, 2025 RoP, on affidavit. | Within **2 weeks** |
| **To Respondents** | File their respective replies. This is noted as a **”final opportunity.”** | Within **2 weeks** (with advance copy to Petitioner) |
| **To Petitioner (APTRANSCO)** | File rejoinder (response to respondents’ replies), if any. | Within **1 week** thereafter |
| **Next Hearing** | Petition listed for next hearing. | **May 14, 2026** |

#### 5. Business & Strategic Implications

– **For APTRANSCO:** The petition seeks to recover transmission charges for assets used to facilitate inter-State power flow. Successful tariff determination would enable APTRANSCO to receive compensation under the POC mechanism, impacting its revenue and cost recovery for the specified period (November 2020 – March 2021).

– **For Respondents (including TANTRANSCO):** Non-appearance and failure to file replies have resulted in a “final opportunity” being granted. Continued non-compliance could lead to the Commission proceeding *ex parte* (in their absence), potentially resulting in tariff determination without their inputs.

– **Regulatory Process:** The case highlights the procedural rigor of tariff determinations before CERC. Non-compliance by parties can delay proceedings, but the Commission is providing clear deadlines to move the matter toward resolution.

– **Timeline Consideration:** With the next hearing scheduled for May 14, 2026, a final order on tariff determination may be expected in the subsequent months, depending on compliance by all parties.
