Should a customer32 under a PRES decide to revert to postpaid service, a bill deposit equivalent to the average monthly purchase for the past six (6) months has to be paid by the said customer prior to the reconnection to a postpaid service.


Subject to the availability of a DU’s prepaid electric service infrastructure:

3.1 Customers have the option to apply for a PRES33 on a voluntary basis.

3.2 Customers should be allowed to avail of the PRES34 on a trial basis for a period of six (6) months to give them the opportunity to assess the impact of using the prepaid service.

7.2 Separability Clause

Pasig City. October 1, 2012.



1 The coverage of Prepaid Retail Electric Service (PRES) in the original Rules was limited only to residential customers. Hence, the word “customers” appearing in the original text has a preposition “residential” so as to imply that the specific provision applies only to residential customers availing of the PRES. However, in the amended text, the word “residential” was deleted so that the word “customers” will now be referring to all customer classes availing of the PRES.

Original text – “1.1.1 Provide residential customers a choice for all energy management strategies;”

2 The abbreviations of PRES and PMS which stand for “Prepaid Retail Electric Service” and “Prepaid Metering System”, respectively, are introduced in the amended text of Sub-Section 1.1.2. Likewise, the first letter of each word in the phrase “prepaid metering system” which appears in the original text is capitalized in the amended text for being now included in the Definition of Terms.

Original text – “1.1.2 Establish technical standards for Prepaid Retail Electric Service using a prepaid metering system”;

3 The terms “Prepaid Retail Electric Service” and “Prepaid Metering System” are replaced in the amended text by their abbreviations PRES and PMS, respectively.

Original text – “1.1.3 Establish rules for Prepaid Retail Electric Service using a prepaid metering system in addition to all other applicable existing customer protection rules.”
