CERC defers reserve-shortfall sharing of DSM pool deficits to April 2027
Current arrangement in force till: 4 April 2027
CERC has put off by six months the rule that would make states with reserve shortfalls pay for deficits in the deviation and ancillary services pool. The current arrangement continues until 4 April 2027.
Why it matters. States get six more months to build reserve capacity before they start paying for pool deficits.
What changes
- Regulation 9(7)(i) of the DSM Regulations 2024 stays in force until 4 April 2027, instead of 4 October 2026.
- The new mechanism under Regulation 9(7)(ii), sharing deficits in proportion to reserve shortfalls allocated by NLDC, starts on 5 April 2027.
- Grid-India must prepare a detailed recovery procedure, including how shortfalls are calculated and deficits allocated, and submit it for approval before 4 April 2027.
- Reasons cited: the resource adequacy framework is still evolving, and only 7 of 34 states and entities had reported data on reserve capacity.
- Issued under CERC's power to remove difficulties (Regulation 12); it follows a first deferral on 30 March 2026 (02/SM/2026).
