Navigating the Philippine Electric Power Industry: Mandatory vs Voluntary Migration

The Philippine electric power industry is undergoing a historic transition. Republic Act No. 9136, or the Electric Power Industry Reform Act of 2001 (EPIRA), envisioned a shift from a monopolized, regulated market to one where qualified electricity end-users can choose their own suppliers. A key question has always been: when does this shift become mandatory, and when is it voluntary? In a consolidated decision dated March 21, 2021, the Supreme Court settled this question, striking down rules that forced contestable customers to leave their distribution utilities.

The Legal Framework: EPIRA and Retail Competition

Before EPIRA, all electricity end-users were "captive" — they had no choice but to buy power from the utility serving their area. EPIRA changed this by introducing Retail Competition and Open Access (RCOA), which allowed qualified end-users to choose their electricity supplier.

The EPIRA provides the framework for restructuring the electric power industry, including the privatization of National Power Corporation assets and the transition to a competitive structure. Under Section 31 of the EPIRA, the Energy Regulatory Commission (ERC) is directed to allow electricity end-users meeting certain demand thresholds to participate in the contestable market. The exact statutory text of Section 31 is not reproduced in the library materials available for this article, but the Supreme Court decision quotes the provision, including the phrase "shall allow" and the threshold of one megawatt for the initial contestable market.

The Department of Energy (DOE) and the ERC issued implementing rules to operationalize RCOA. The controversy arose when these agencies issued issuances that compelled qualified end-users to migrate to the contestable market, rather than merely allowing them to do so.

The Assailed Issuances

In June 2015, the DOE issued Department Circular No. DC2015-06-0010, which mandated all contestable customers with an average peak demand of at least 1 MW to secure a retail supply contract by June 25, 2016. The ERC then issued Resolution Nos. 5, 10, 11, and 28 (all series of 2016), which set deadlines for mandatory migration, imposed restrictions on distribution utilities, and prohibited local retail electricity suppliers from entering into new contracts.

These issuances effectively forced contestable customers to leave their distribution utilities and contract with licensed retail electricity suppliers. Failure to do so could result in physical disconnection or paying a premium as a "supplier of last resort."

The Issue: Mandatory or Voluntary?

Several groups — including universities, businesses, and electric cooperatives — challenged these issuances before the Supreme Court. They argued that the EPIRA made migration voluntary, not mandatory. The government agencies, on the other hand, insisted that the law required qualified end-users to migrate.

The Supreme Court sided with the petitioners. The Court ruled that the phrase "shall allow" in Section 31 of EPIRA is permissive, not mandatory. It means the ERC must permit qualified end-users to enter the contestable market — but it does not compel them to do so. Migration to the contestable market is a right, not an obligation.

The Court's Ruling

The Court held that the DOE and ERC exceeded their authority when they issued rules mandating migration. Subordinate legislation must be germane to the objects and purposes of the law and must conform to the standards prescribed by the law. By imposing mandatory migration, the agencies rewrote the law rather than implemented it.

The Court also emphasized the separation of powers. The DOE is tasked with formulating rules to animate EPIRA's policy objectives, while the ERC implements those rules. Neither agency may supplant the law with its own policy choices.

Notably, the DOE itself later admitted its error. In November 2017, it issued new circulars revoking the mandatory migration policy, acknowledging that its earlier circular was inconsistent with EPIRA.

Practical Takeaways

• Migration to the contestable market is voluntary. Qualified end-users may choose to stay with their distribution utility or switch to a retail electricity supplier. They cannot be forced to leave.
• The DOE and ERC cannot impose requirements beyond the law. Agency issuances must be consistent with EPIRA. Rules that effectively amend the law are void.
• Distribution utilities may still serve contestable customers. The assailed prohibition on distribution utilities participating in the contestable market was struck down. End-users retain the option to be served by their local utility.
• The Court's ruling applies to similar future issuances. Any new DOE or ERC rule that mandates migration or restricts end-user choice must be carefully scrutinized against EPIRA's actual text.
• Consult the current rules before acting. While this decision settled the mandatory vs. voluntary question, the RCOA framework continues to evolve. Check the latest DOE circulars and ERC resolutions for current thresholds and procedures.
