On December 16 last year, the government, through the Energy Commission (EC), gave Tenaga Nasional the approval to continue implementing the Imbalance Cost Pass-Through (ICPT) mechanism for the period of Jan 1 to June 30, 2023. ICPT is a mechanism under the Incentive Based Regulation (IBR) framework which allows for Tenaga Nasional (TNB) to reflect changes in fuel and other energy generation-related costs in the electricity tariff.
