The Supreme Court affirmed the Energy Regulatory Commission’s (ERC) approval of Manila Electric Company’s (MERALCO) distribution rates under the Performance-Based Regulation (PBR) methodology. This decision upheld the ERC’s authority to shift from the Rate of Return Base (RORB) to PBR, emphasizing that challenges to administrative regulations must be made directly, not collaterally. The ruling impacts electricity consumers by affirming the regulatory framework that governs how MERALCO sets its rates, balancing the need for fair pricing with the utility’s operational and investment needs.
Power Rates and Public Interest: Can Regulators Change the Rules?
This case revolves around the petitions filed by the National Association of Electricity Consumers for Reforms (NASECORE), Federation of Village Associations (FOVA), and Federation of Las Piñas Village Associations (FOLVA) against the Manila Electric Company (MERALCO). The petitioners questioned the validity of the rates set by MERALCO under the Performance-Based Regulation (PBR) methodology approved by the Energy Regulatory Commission (ERC). At the heart of the matter was whether the ERC correctly upheld MERALCO’s applications for translating its approved Annual Revenue Requirement (ARR) into distribution rates for the regulatory period of 2007-2011.
The legal battle began when MERALCO sought approval for revised rate schedules, leading to the enactment of the Electric Power Industry Reform Act of 2001 (EPIRA), which mandated electric distribution utilities to apply for approval of their unbundled rates with the ERC. Initially, the ERC adopted the Rate on Return Base (RORB) methodology. The ERC then shifted to the PBR methodology in 2003. This shift was formalized through Resolution No. 4, Series of 2003, marking a significant change in how electricity prices were regulated.
The PBR methodology, unlike RORB, controls the price of electricity through an average price cap mechanism. This mechanism limits the average revenue per kWh that a utility can earn within a specific period. Following this shift, the ERC issued Resolution No. 12-02, Series of 2004, known as the Distribution Wheeling Rate Guidelines (DWRG), which governed the setting of distribution rates for privately-owned distribution utilities entering the PBR system. MERALCO was among the first entrants into the PBR system.
The ERC further refined the regulatory framework by issuing Resolution No. 39, Series of 2006, which promulgated the Rules for Setting Distribution Wheeling Rates (RDWR). The RDWR set a maximum price cap on distribution wheeling rates for regulated entities. MERALCO subsequently filed an application for the approval of its ARR and performance incentive scheme for the 2007-2011 regulatory period. A draft determination was issued, and public consultations were held, but the petitioners failed to actively participate despite being notified.
After considering all submissions, the ERC approved MERALCO’s application with significant adjustments. MERALCO then filed separate applications to translate the approved ARR into distribution rates for different customer classes for the first and second regulatory years of 2007-2011. The petitioners contested these applications, arguing that the PBR methodology was inconsistent with the EPIRA and that the ERC should have revisited its assumptions regarding the increased RORB rate from previous cases. They also asserted that a complete audit by the Commission on Audit (COA) was necessary before approving MERALCO’s applications.
The Court of Appeals (CA) affirmed the ERC’s decision, stating that a review of the assumptions used in the provisional rate increase was unnecessary due to the adoption of the PBR methodology. The CA also dismissed the need for a COA audit, citing the Lualhati case, which held that such an audit was not indispensable. Unconvinced, the petitioners elevated the case to the Supreme Court, questioning the CA’s ruling and reiterating their arguments against the PBR methodology and the lack of a COA audit.
The Supreme Court emphasized that administrative regulations have the force of law and enjoy a presumption of constitutionality and legality. These regulations cannot be attacked collaterally. In this case, the petitioners’ challenge to the PBR methodology was deemed a collateral attack since it was not made through a direct proceeding specifically questioning the validity of the DWRG and RDWR. The Court noted that the proceedings in question pertained to the translation of the Maximum Annual Price (MAP) into distribution rates, a step subsequent to the adoption of the PBR methodology.
Moreover, the Supreme Court highlighted that the petitioners had ample opportunity to raise objections during the public consultations conducted by the ERC regarding the shift to the PBR methodology. Their failure to do so, coupled with the finality of the ERC’s decision in ERC Case No. 2006-045 RC, precluded them from questioning the methodology at this stage. The Supreme Court stated:
Based on the foregoing, it is therefore evident that petitioners were given an ample opportunity to question the ERC’s shift to the PBR methodology, including its application relative to MERALCO’s rate propositions, but to no avail. Consequently, they can no longer question the judgment rendered in said case which had long become final and executory and hence, immutable.
Furthermore, the Court pointed out that resolving the petition would entail determining factual matters, which is generally prohibited in petitions for review on certiorari under Rule 45 of the Rules of Court. The petitioners contested the reasonableness of the rates approved by the ERC, presenting data to show MERALCO’s financial position. MERALCO, in turn, challenged these assertions, clarifying that the petitioners had made incorrect assumptions about the company’s investments.
The Supreme Court clarified that a question of fact arises when the appellate court cannot determine the issue without reviewing or evaluating evidence. Assessing the reasonableness of the rates required scrutinizing the veracity of both parties’ allegations and examining supporting evidence. Therefore, the issue of reasonableness was deemed a question of fact, falling outside the scope of a Rule 45 petition. The Court acknowledged that rate-fixing involves technical examination and specialized review, which are best left to the expertise of the administrative authority.
Regarding the COA audit, the Supreme Court clarified that the directive in the Lualhati case pertained to MERALCO’s rates under the RORB system. With the shift to the PBR methodology, the premises and assumptions differed significantly. Under RORB, rates were set to recover historical costs, while PBR uses projections of operating and capital expenditures. The Court explained:
Because of the variances in its premises and assumptions, the ERC’s shift from the RORB to the PBR methodology should therefore be deemed as a supervening circumstance that rendered inconsequential this Court’s provisional approval of the rate increases applied for by MERALCO in Lualhati which was made under the context of the now-defunct RORB system. Accordingly, the issue of whether or not the ERC should have first took into account the findings in the COA audit before approving MERALCO’s applications in ERC Case Nos. 2008-004 RC and 2008-018 RC as directed in Lualhati has become moot and academic.
Therefore, the requirement for a COA audit under Lualhati was no longer applicable due to the supervening shift to the PBR methodology.
FAQs
What was the key issue in this case? | The key issue was whether the Court of Appeals correctly upheld the ERC’s decision to approve MERALCO’s distribution rates under the PBR methodology, and whether this methodology was legally sound. |
What is the Performance-Based Regulation (PBR) methodology? | PBR is a rate-setting methodology that controls the price of electricity through an average price cap mechanism, limiting the revenue per kWh a utility can earn, promoting efficiency and innovation. |
What is the Rate of Return Base (RORB) methodology? | RORB is a rate-setting methodology where power rates are set to recover the cost of service prudently incurred, including historical costs, plus a reasonable rate of return. |
Why did the petitioners challenge MERALCO’s rates? | The petitioners challenged MERALCO’s rates because they believed the PBR methodology was inconsistent with the EPIRA and led to unreasonable and unjustified rates, resulting in excessive profits for MERALCO. |
What did the Court rule about the ERC’s shift to PBR? | The Court ruled that the ERC had the authority to adopt the PBR methodology and that the petitioners’ challenge was a collateral attack on administrative regulations, which is not permissible. |
Was a COA audit required before approving MERALCO’s rates? | The Court determined that the COA audit required under the Lualhati case was no longer necessary because the ERC had shifted from the RORB to the PBR methodology, which has different premises and assumptions. |
What was the significance of the Lualhati case in this context? | The Lualhati case directed a COA audit under the RORB system, but the Supreme Court deemed this requirement moot due to the supervening shift to the PBR methodology, making the audit no longer applicable. |
What does it mean to say that the petitioners launched a collateral attack? | A collateral attack means challenging the validity of a regulation in a case where the primary issue is different (in this case, the specific rates). Such attacks are not allowed; challenges must be made directly in a case specifically questioning the rule’s validity. |
What opportunity did the petitioners have to object to the PBR method? | The petitioners were invited to public consultations and hearings where they could have raised their concerns about the shift to the PBR methodology but failed to do so, which the Court considered a waiver of their right to object later. |
In conclusion, the Supreme Court’s decision underscores the importance of adhering to established regulatory frameworks and challenging administrative regulations through proper legal channels. The ruling affirms the ERC’s authority to adopt modern rate-setting methodologies like PBR, promoting efficiency and innovation in the electric power industry, while ensuring reasonable rates for consumers.
