Case Summary (G.R. No. 246940)

Statutory and Regulatory Framework

The EPIRA reorganized the electric power industry into generation, transmission, distribution, and supply, and created the ERC as an independent quasi-judicial regulator. Among the ERC’s functions were the promotion of competition and market development, and the establishment and enforcement of rate-setting methodology to ensure reasonable electricity prices at non-discriminatory rates, while enabling the recovery of just and reasonable costs.

Pursuant to these mandates, the ERC adopted automatic adjustment mechanisms and confirmation processes for distribution utilities. The October 13, 2004 Order in ERC Case No. 2004-322 adopted guidelines for automatic adjustment of generation rates and system loss rates by distribution utilities, including a post-verification rule requiring the ERC to verify generation cost recovery and system loss rate portions at least every six (6) months, with deemed finality and confirmation if the ERC failed to verify within that period.

Subsequently, the ERC consolidated and systematized the automatic cost adjustment and true-up mechanisms through ERC Resolution 16-09 (issued on July 13, 2009), which set formulae for adjusted rates and the method to calculate over/under-recovery for multiple components including generation, transmission, system loss, lifeline subsidy, franchise and business taxes, and related mechanisms. The ERC later amended portions of these rules through ERC Resolution 21-10 on October 18, 2010 with respect to the formula for system loss rate over/under-recovery. Resolution 16-09 also directed distribution utilities to file applications for approval of their over/under-recoveries based on the consolidated formulae, intended to protect consumers by ensuring accuracy and reasonableness of amounts billed and collected.

INEC’s Application and Over/Under-Recoveries Sought

Following the regulatory issuances, distribution utilities filed applications for ERC approval of their over/under-recoveries. INEC, as a distribution utility, filed its application docketed as ERC Case No. 2011-023 CF. INEC’s application requested ERC confirmation of over/under-recoveries for the period 2004 to 2010, broken down by mechanism as follows: Generation (2,364,668.01), Transmission (2,443,468.24), System Loss 435,860.11, Lifeline Subsidy 1,445,533.37, Inter-Class Cross Subsidy 1,433,730.70, and Prompt Payment Discount (6,522,060.66), with a total (8,015,072.73) in the over/under-recoveries as presented in the application.

Ruling of the ERC on August 12, 2013

On August 12, 2013, the ERC granted INEC’s application, but with modifications. The ERC approved the application with modification and ordered INEC to refund specified amounts representing over-recoveries, to begin from the next billing cycle after receipt of the decision, and to continue until the entire refund amount would be fully returned to customers. The refund directive covered generation, transmission, system loss, lifeline subsidy, inter-class cross subsidies, and a reinstated prompt payment discount, with each component specified in amounts and corresponding per-kWh or per-customer-class rates.

The ERC computed the total over-recovery of INEC at P479,784,177.48 covering 2004 to 2010. It also imposed compliance requirements, including sworn statements, the manner of reflecting over-recoveries in monthly computations using prescribed acronyms, and periodic submission of reports in accordance with a prescribed format until full refund was achieved.

ERC’s Partial Reconsideration Order Dated May 30, 2017

INEC moved for reconsideration, seeking recomputation of its over/under-recoveries and, alternatively, an extension of the refund implementation period. The ERC, in an Order dated May 30, 2017, partially granted the motion. It allowed recomputation of generation over-recoveries by considering Net Settlement Surplus (NSS) reflected in a report certified by PEMC’s billing settlement and metering manager. The ERC denied other recomputation requests, including those for system loss using the previous month’s method, transmission rate, and inter-class cross subsidy.

At the same time, the ERC extended the refund period from 36 months to 48 months. It confirmed re-computed over/under-recoveries for the period November 2004 to December 2010, with the total over-recovery reduced to P394,911,640.39, and it set forth the corresponding overall tariff adjustment and total KWh sales used in the calculation.

CA Proceedings and Rulings

INEC elevated the dispute to the CA via a Petition for Review, challenging the manner of computation of its over-recoveries and the alleged retroactive application of Resolution 16-09 to earlier transactions. In its Decision dated November 15, 2018, the CA affirmed the ERC’s August 12, 2013 Decision and the May 30, 2017 Order.

The CA ruled that applying Resolution 16-09 to transactions prior to 2009 did not divest INEC of any vested right over a specific formula. The CA also held that ERC was entitled to reasonable leeway in confirming the correctness and fairness of power rates under the EPIRA regulatory regime. Further, the CA found that ERC sufficiently explained the formulae used for computing INEC’s over-recoveries and that INEC’s right to procedural due process was respected.

The CA denied INEC’s motion for reconsideration for lack of merit in a Resolution dated May 3, 2019.

Issues Raised Before the Supreme Court

INEC’s petition presented four main grounds for the Court’s consideration: first, the CA’s alleged error in finding that INEC did not prove that ERC failed to verify the generation and system loss rate within the relevant period; second, the alleged violation of substantive due process arising from the retroactive application of Resolution 16-09 that purportedly deprived INEC of property rights; third, the alleged grave abuse of discretion by ERC in denying a motion for data and information that allegedly formed the basis of ERC’s recomputation, purportedly violating procedural due process; and fourth, the CA’s alleged affirmance of error in ERC’s recomputation of over-recoveries.

Material Date and Verification of Generation and System Loss Rates

The petition challenged the CA’s statement that INEC did not show the material dates to prove ERC’s failure to verify the generation and system loss rates and that, without knowing when INEC submitted its calculation and when the verification period commenced, the rates could not be deemed final and confirmed.

INEC argued that this position conflicted with the CA’s earlier narration that it applied to ERC for confirmation on 26 May 2011, docketed as ERC Case No. 2011-023 CF, and set for initial hearing on 12 August 2011, and that those findings underpinned the CA’s conclusions on generation and system loss rates. INEC invoked Section 2, Article V of ERC Case No. 2004-322, which provided that at least every six months ERC should verify generation cost recovery and the relevant portion of system loss attributable to generation costs. INEC insisted that ERC did not conduct such verification and that the failure to verify within six months meant the rates became final and confirmed.

The Court held that INEC raised the issue only for the first time on appeal, contrary to settled rules that issues not raised in lower proceedings cannot be raised for the first time on appeal. The Court also noted that when INEC applied for approval of over/under-recoveries, it did so pursuant to Resolution 16-09 as amended by Resolution 21-10, and in its motion for reconsideration before the ERC it raised other specific computational issues, including generation rate recomputation using NSS data, system loss computation using the previous month cost, transmission rate confirmation, and effects on lifeline subsidy, inter-class subsidy, and refund terms, but did not timely raise the post-verification “material date” issue.

The Court further rejected the argument that the alleged misapprehension, even assuming inconsistency in the CA’s statements, was material enough to change the outcome, especially because the CA affirmed ERC’s findings and the challenged matter was not raised before the ERC.

Alleged Retroactive Application and Substantive Due Process

INEC further argued that because the generation and system loss rates allegedly became final and confirmed when ERC failed to verify within six months, INEC’s property rights to collections from monthly billings and related entitlements had vested. INEC claimed that ERC’s retroactive application of Resolution 16-09 impaired those vested rights and violated substantive due process.

The Court examined the regulatory chronology. It noted that the ERC issued an October 13, 2004 Order adopting guidelines for automatic adjustment of generation and system loss rates, and it was followed by Resolution 19-05 in 2005 for transmission rate computations. Then, in 2009, Resolution 16-09 consolidated and systematized the automatic cost adjustment mechanisms and set up a confirmation process for multiple mechanisms including automatic generation rate and system loss adjustment, transmission rate adjustment, lifeline rate recovery, local franchise and business tax recovery, and specific guidelines for computing over/under-recovery and true-up for multiple components.

The Court held that the issuance of Resolution 16-09 did not take away any vested rights as claimed by INEC. It explained that ERC Case No. 2004-322 already provided for the verification process, while Resolution 16-09 mainly adopted the formulae and the manner of implementing that process for post-verification and confirmation. Thus, Resolution 16-09 did not create a new obligation or impose a new duty on INEC. The Court considered the issuance of Resolution 16-09 as prescribing the means by which verification and confirmation would be conducted.

The Court found persuasive the reasoning in ASTEC, et al. v. Energy Regulatory Commission, where the Court
