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 (Energy Input) and the energy deiivered to the end-users and other entities connected 
to the system (Energy Output). This entails that end-users are required to pay for the energy 
that they do not directly consume. The rate depends on the system loss cap set and 
determined by the Energy Regulatory Commission (ERC) based on load density, sales mix, 
cost of service, delivery voitage and other technical considerations.
In 2019, the average level of system loss of electric cooperatives was 10.16%. Despite 
the high rate, 15% of the total number of electric cooperatives exceeded the said allowable 
system loss cap. A few years later, the ERC decided to maintain the approved iower cap of 
5.5% from 2022 onwards pending the compietion of studies or reviews on the same.
Instead of shifting the burden or cost of system loss to end-consumers, distribution 
utilities should enhance their systems for the reduction of eiectricity iosses and ensure that 
transmission grid designs do not contribute to such losses.
With this measure, the ERC is mandated to encourage and promote a reduction in 
system losses through an incentive scheme or program for performance improvement for the 
benefit of the consumers or end-users. The ERC is aiso required to review and assess every 
three years whether there is a need to lower the system loss cap.


In view of the foregoing, the immediate passage of this bill is earnestly sought.

REDUCING THE RECOVERABLE SYSTEM LOSS RATE AND FOR OTHER
3 
PURPOSES
Be it enacted by the Senate and the House of Representatives of the Philippines 
in Congress assembled:
4 
SECTION 1. Tide. — This Act shall be known as the "Recovery System Loss Act."
5 
SECTION 2. Declaration of Policy. — It is hereby the declared the policy of the State
6 
to ensure the quality, reliability, security, and affordability of supply of electric power while
7 
taking into consideration the viability of all distribution utilities and the protection of rights of
8 
every consumer. Towards this end, the State shall ensure that the imposition of electricity
9 
charges to the public is justifiable, equitable, and reflects the true cost of electricity.
10 
As a nation, we recognize the critical role that energy supply and its affordability play
11 
in ensuring economic growth, environmental sustainability, and national security.
12 
The State acknowledge that affordable energy is essential for economic growth and
13 
social equity. Therefore, the State will work to ensure that energy prices are reasonable and
14 
reflect the true cost of production and distribution, while also taking into account the impact
15 
on low-income households and vulnerable communities.
16 
The State recognizes that a secure energy supply is critical for our national security
17 
and economic stability. Therefore, it will promote domestic energy production, reduce our
18 
reliance on foreign sources of energy, and strengthen energy infrastructure and resilience.
