The TNERC’s order, issued on April 25, 2023, came in response to MP No. 8 of 2023 filed by Dollar Industries. The project will allow the stored energy to be exported to the grid during peak hour slots.


The commission praised the petitioner for taking the initiative in implementing an energy storage system and permitted them to adjust the stored energy exported to the grid in the respective slots and blocks, including the peak hour slot. The current harmonics must be maintained by the petitioner as stipulated in the Supply Code of the Commission, and all applicable chargers and related terms and conditions must adhere to the regulations and orders of the Commission.
