Residential: Php 10.2729/kWh
Low Voltage: Php 9.3976/kWh
High Voltage: Php 7.5882/kWh

𝗚𝗲𝗻𝗲𝗿𝗮𝘁𝗶𝗼𝗻 𝗖𝗵𝗮𝗿𝗴𝗲
For the May billing period, the total generation mix rate increased by Php 0.2496/kWh, mainly due to the significant rise in the Spot Energy Rate purchased from the Wholesale Electricity Spot Market (WESM). This increase in spot prices occurred as available power supply in the market tightened, resulting in higher generation costs for the month.

Despite the increase in generation charge, decreases in other bill components—including the Transmission Rate, System Loss Rate, and Senior Citizen Subsidy Charge—helped temper the overall increase in electricity rates for the month of May. As a result, the increase in power rates compared to April remained minimal.

𝗧𝗿𝗮𝗻𝘀𝗺𝗶𝘀𝘀𝗶𝗼𝗻 𝗖𝗵𝗮𝗿𝗴𝗲
Transmission charges continue to reflect regulatory adjustments approved by the Energy Regulatory Commission (ERC) for the National Grid Corporation of the Philippines (NGCP).

As part of the ERC’s Fifth Regulatory Period (2023–2027), the Commission approved a revenue requirement for NGCP that is lower than its initial application, following a thorough review of its proposed costs, investments, and projects.

This regulatory reset ensures that only necessary and validated expenses—such as grid upgrades, system improvements, and reliability projects—are included, while protecting consumers from excessive charges.

The ERC also disallowed certain costs, such as real property taxes, from being passed on to consumers, in line with existing legal rulings.

Overall, these adjustments aim to strike a balance between maintaining a reliable and efficient power transmission system and keeping transmission charges reasonable for electricity consumers.

*Please note that power rates may vary in some municipalities or cities due to local taxes imposed by the LGU, including Business Tax, Franchise Tax, and Real Property Tax. These local charges affect the total electricity rate reflected in your billing statement.
