RECEIVE! IV:
Introduced by Senator WIN GATCHALIAN
AN ACT REDUCING THE RECOVERABLE SYSTEM LOSS RATE AND FOR
OTHER PURPOSES
EXPLANATORY NOTE
System loss is the difference between the electric energy delivered to the distribution 
system and the energy delivered to the end-users and other entities connected to the 
system. Although it is energy that end-users do not consume, they are made to pay 
for it through the system loss charge. However, this charge is dependent on the 
system loss cap determined by the Energy Regulatory Commission (ERC).
On April 23, 2028, the ERC issued ERC Resolution No. 10 Series of 20181 clarifying the 
System Loss Calculation and Providing the Effectivity of the Rules for Setting the 
Distribution System Loss Cap. The resolution set the maximum level of system loss 
that distribution utilities may recover from customers through the system loss charge 
known as the system loss caps. Under the resolution, the system loss cap for private 
distribution utilities (PDUs) is set at 6.5% for 2018 which will then be reduced to 
6.25% in 2019, 6% in 2020 and 5.5% in 2021 and onwards. The same resolution 
states that for electric cooperatives (ECs), the system loss cap is 12% in 2018, a range 
of 11% to 12% in 2019, a range of 10% to 12% in 2020, a range of 9% to 12% in 
2021 and a range of 8.25% to 12% from 2022 onwards.
1 Entitled 'A Resolution Clarifying the System Loss Calculation and Providing the Effectivity of the Rules for Setting the 
Distribution System Loss Cap'.


These caps, determined seven years ago or in 2018, still regulate the system loss 
charges, to the detriment of consumers.
This measure requires the ERC to review, every three years, whether the system loss 
caps should be decreased and to devise a performance incentive scheme to encourage 
system loss reduction. Failure of the ERC to do so would subject it to penalty. 
Through this bill, it is hoped that distribution utilities will be incentivized to improve 
their operations resulting to a decrease in system losses and savings for the Filipino 
household.
Given the foregoing, the immediate passage of this measure is sought
