TN SLDC has filed a petition for the FY 2024-25 on the DSM Charges for Wind and Solar Generators. The petition proposes to re-fix the ceiling rates of DSM charges for the FY 2025-26 with effect from 01.04.2025 and DSM charges to be re-fixed to 1000% of ceiling rate from the generators who do not appoint QCA beyond 90 days. Our comments and suggestion on the matter are broadly outlined below:
- Remove cap for deviation charges, or increase the cap (solar (10 p/unit) and wind (15 p/unit))
- Consider increasing penalty charges, by either linking penalty charges to PPA or contract rate, or increasing absolute charges
- Better public data reporting is needed, both at individual plant and aggregated level
- Need for further detailed analysis and preparing for a future ready DSM framework
- Linking deviation charges to frequency: Initiate study to assess the implication of RE deviations on the grid frequency.
- Aggregating Solar QCAs in the state for more substantial savings in deviation charges
- Including Hybrid RE and standalone ESS under DSM framework
- Shift energy accounting to scheduled generation
Our comments and suggestions in this matter are detailed in the attached submission.
