### **3. Business & Regulatory Implications**
* **Financial Impact for Delhi:** The outcome will determine the finalized transmission costs that DTL (and ultimately Delhi consumers via BRPL/BYPL) must pay for using these critical inter-state lines, impacting power purchase costs.
* **Revenue Certainty for PGCIL:** The truing up for 2019-24 will settle any pending revenue adjustments with PGCIL as the line owner.
* **Clearing Regulatory Backlog:** The hearing on the **remanded petition (175/2017)** is crucial to close a long-pending regulatory issue from the previous tariff period.
* **Confidentiality of Data:** DTL’s submission in a **”sealed cover”** suggests the information may be commercially sensitive or pertain to contested capital costs, to be reviewed first by the Commission.
* **Stakeholder Alignment:** The active participation of Delhi’s discoms (BRPL/BYPL) highlights their direct financial interest as the ultimate payers of the determined transmission charges.
