"The filing was in compliance with ERC's Dec. 24 order, which declared the period July 2022 to June 2025 as lapsed period and which ordered Meralco to submit a proposal to refund the difference between Meralco's actual weighted average tariff AWAT during the said period and the ERC-approved MAP for Meralco of around P1.35 per kWh," Meralco head of utility economics Lawrence Fernandez said. Meralco sought for the issuance of a provisional authority to implement the refund, pending the final approval of the application. It also asked the ERC to offset its over-refund in the implementation of the distribution rate true up for July 1, 2015 to June 30, 2022 amounting to P862 million. The amount is lower than Meralco's earlier estimate of P16 billion.
