### **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.
