  • Jamnagar gigafactory commissioning milestones and GWh output
  • Domestic EV and grid-storage BESS demand data
  • PLI ACC scheme disbursement and localization mandates
  • Chinese input pricing and export controls on battery materials
  • Any counter-duty or safeguard on finished cell imports
  • RIL fast-tracks Jamnagar BESS commissioning toward 40 GWh initial phase
