This ruling aims to correct imbalances in the power sector, ensuring fair competition and encouraging efficient energy use. The court emphasized that the ERB acted within its jurisdiction to regulate power rates and that the rate differential was designed to assist utility companies in attracting bulk power customers, without compelling direct consumers to switch providers. This decision underscores the importance of regulatory bodies in fostering a competitive and sustainable energy market.

Power Play: Can Rate Differentials Level the Energy Playing Field?

This case revolves around a decision by the Energy Regulatory Board (ERB) to implement a new power rate structure in the Mindanao Grid. National Steel Corporation (NSC), a major steel manufacturer and a direct power consumer from the National Power Corporation (NAPOCOR), challenged this decision. The core of the dispute lies in the ERB’s decision to introduce a 12% power rate differential between “utilities” (local power distribution companies) and “non-utilities” (direct consumers like NSC). NSC argued that this rate hike was intended to force them and other direct consumers to disconnect from NAPOCOR. This raises the central question: does the ERB’s decision, aimed at assisting utility companies, unfairly discriminate against direct power consumers?

The narrative begins with NAPOCOR’s application to the ERB for a new power rate structure in Mindanao. NAPOCOR sought to increase power rates for both utilities and non-utilities. The Association of Mindanao Industries (AMI), of which NSC is a member, initially supported the restructuring, believing it would correct inefficiencies in the power sector. However, other parties advocated for a larger rate difference between utilities and non-utilities, arguing that the minimal 2% difference proposed by NAPOCOR was discriminatory.

The ERB, after conducting hearings, approved a new rate structure with a wider margin. The ERB articulated its rationale for approving the new rate structure. The board emphasized the need to correct deficiencies in the existing rate structure, which did not properly allocate fixed and variable costs and failed to protect distributing utilities. According to the ERB, the existing rate structure provided little incentive for industrial customers to purchase power from distribution utilities. The goal was to encourage efficient use of energy resources and enable NAPOCOR to provide reliable service. The board noted that a 10% rate advantage was initially afforded to utility customers to assist them attain viability by attracting bulk power customers into their system.

The ERB further found that adjustments made since 1980 eroded the rate difference down to a little over 2%, thereby forgetting the thrust of assistance to the utilities. Intervenors AMI and NAPOCOR then filed their separate motions for reconsideration. However, the ERB directed NAPOCOR to implement its February 28, 1997 decision, despite the unresolved motions for reconsideration. This prompted NSC to file a petition for certiorari and prohibition with the Court of Appeals, seeking to halt the implementation of the new rates.

The Court of Appeals (CA) ultimately denied NSC’s petition. The CA saw no merit in NSC’s arguments and upheld the ERB’s decision. NSC then elevated the case to the Supreme Court, arguing that the 12% rate differential was unjust and intended to compel direct consumers to disconnect from NAPOCOR. The Supreme Court, however, sided with the Court of Appeals and the ERB, affirming the decision to implement the new power rate structure.

The Supreme Court emphasized that the ERB was vested with the authority to fix power rates. Section 4 of R.A. No. 6395, as amended, grants the ERB the power to “determine, fix and prescribe the rates being charged” by NAPOCOR. The court found that the ERB acted within its jurisdiction in approving the new rate schedules. The court distinguished this case from others involving disputes over the right to supply electric power, such as NAPOCOR vs. Court of Appeals and Phividec Industrial Authority vs. Court of Appeals, wherein the determination of which of the two public utilities should have the right to supply electric power to an area, a controversy clearly dealing with the question of regulation and distribution of energy resources, was the issue.

The Supreme Court also highlighted the absence of compulsion in the ERB’s decision. The court agreed with the appellate court’s finding that the 12% rate differential was designed to protect utility companies like ILIGAN by allowing them to charge lower rates than NAPOCOR. However, the Court stressed that this encouragement did not amount to compulsion. NSC remained free to source its power from NAPOCOR if it chose to do so. In the words of the appellate court:

“A decision of the public respondent approving a power rate structure, which is clearly within its jurisdiction, does not become a decision ordaining a power distribution, simply because it will have the effect of encouraging the petitioner to disconnect from NAPOCOR and connect with ILIGAN.”

The Supreme Court underscored that the appropriate remedy to challenge the ERB’s orders was an appeal, not a petition for certiorari. Certiorari is only available when there is no appeal or other adequate remedy. In this case, NSC had the option to appeal the ERB’s decision, making certiorari an inappropriate recourse.

Building on this, the Supreme Court highlighted the purpose of the ERB’s decision. The object of NAPOCOR’s application with the ERB was designed to correct the deficiency of power rates in the Mindanao Grid consistent with the rate restructuring priorly also applied for in Luzon and the Visayas grids. In approving a new rate schedule for the Mindanao Grid, the ERB explained that the existing rate structure in the Mindanao Grid has been designed and implemented in 1980 with demand and energy charges consisting of multi-blocking rate schedules. Because all the rate adjustments since 1980 were tucked into the energy charge, the existing very small rate difference between the utilities and non-utilities in the Mindanao Grid, provides a little incentive for industrial customers to purchase power from the distribution utilities as it gives a strong incentive to the same customers to buy power directly from NPC. The Court cited the ERB’s enumeration of the following deficiencies of NPC’s existing rate structure:

“1.	It does not properly allocate between fixed and variable costs;
“2.	It does not protect the distributing utilities as it competes with the said utilities by giving promotional rates for industries.
“3.	It does not reflect the charges in the consumption profile of its customers.”

The ERB approved a widened margin of 12% to correct the deficiency in the power rates schedule for Mindanao Grid. The Court held that it found no “direct connection” issues as having been tackled by the ERB in approving the modified power rates that would render its decision vulnerable to jurisdictional challenge. The appellate court found “no element of compulsion” on petitioner to source its power through power utility firms.
