Police power vs. electricity industry
In Republic v. MERALCO,[1] the Supreme Court held that rate fixing calls for a
technical examination and a specialized review of specific details which the
courts are ill-equipped to enter, hence, such matters are primarily entrusted
to the administrative or regulating authority.[2] It is undisputed that the ERC has been designated under the EPIRA as the administrative body bestowed
with broad regulatory powers and monitoring functions to ensure the successful
restructuring and modernization of the Philippine electricity industry.
For police power to be deemed as to have been validly exercised, it must have
been necessitated and required by the interests of the consumers generally as
this concept is primarily exerted to further the public welfare. The State
thru the ERC should be able to exercise its police power with great
flexibility when the need arises.[3]

Unusually high and unreasonable market prices may necessitate the ERC to step in and exercise its police power as mandated by the EPIRA.[4]
