Concurrent Authority Investigating Energy Market Breaches in the Philippines

The Supreme Court has settled a significant question in Philippine energy regulation: who has the authority to investigate breaches of the Wholesale Electricity Spot Market (WESM) Rules? In Power Sector Assets and Liabilities Management Corporation v. Energy Regulatory Commission and Philippine Electricity Market Corporation (G.R. No. 193521, April 17, 2023), the Court ruled that the Philippine Electricity Market Corporation (PEMC) and the Energy Regulatory Commission (ERC) exercise concurrent investigative powers over market participants. This decision clarifies the division of authority in the restructured electricity industry and affirms the validity of the arrangement that has governed spot market enforcement since 2008.

The Dispute: Who Investigates WESM Breaches?

The case arose when PEMC sought approval from the Department of Energy to conduct a formal investigation against the Power Sector Assets and Liabilities Management Corporation (PSALM) for alleged breaches of the WESM Rules. The alleged violations involved six power generating plants whose output PSALM traded in the spot market, including non-compliance with dispatch instructions and failure to submit required generation offers.

PSALM challenged PEMC's authority, arguing that the ERC holds exclusive and original jurisdiction over disputes among electricity market participants under the Electric Power Industry Reform Act of 2001 (EPIRA, Republic Act No. 9136). PSALM contended that the ERC could not delegate its powers to PEMC through a memorandum of agreement and protocol executed in 2008.

The Legal Framework Under EPIRA

EPIRA established the WESM and directed the Department of Energy, jointly with industry participants, to formulate its rules. The law also mandated the creation of an autonomous group to implement the spot market. This group became PEMC, a private corporation tasked with preparing for and initially implementing the WESM.

The WESM Rules, formulated after public consultations and endorsed by industry participants, explicitly empower PEMC to investigate alleged breaches and impose sanctions. Under the Rules, PEMC is tasked to ensure that all members comply with the Rules and is empowered to direct the disputes resolution administrator to investigate alleged breaches. The Rules also empower PEMC to impose sanctions on any participant for breach of the Rules. The decision indicates that these sanctions are imposed without prejudice to the ERC's authority to impose fines and penalties under EPIRA, though the exact quoted provision is not available in the ASG law library.

Meanwhile, Section 43(r) of EPIRA gives the ERC responsibility to act against any participant for violations of energy sector laws and rules. However, the Court noted that this provision does not require the ERC to perform all related functions by itself.

The Court's Ruling: Concurrent, Not Exclusive

The Supreme Court denied PSALM's petition and affirmed the Court of Appeals' dismissal of the case. The Court held that the power to investigate violations of the WESM Rules is concurrently exercised by the ERC and PEMC.

The Court reasoned that EPIRA empowered the Department of Energy, together with industry participants, to develop the governance structure of the WESM. This structure, as laid down in the Rules, empowered PEMC to investigate breaches and ensure member compliance. The Court also emphasized that the 2008 memorandum of agreement and protocol did not constitute an undue delegation of the ERC's powers—they merely clarified the working arrangement between the two bodies.

Under the protocol, PEMC has the authority to initially investigate and resolve breach cases. Complaints received by the ERC are referred to PEMC's Enforcement and Compliance Officer at the first instance. However, the protocol draws an important distinction: for anti-competitive behavior, PEMC must refrain from investigating unless directed or allowed by the ERC. For acts constituting both a breach and anti-competitive behavior, PEMC may investigate the breach but must defer to the ERC on the anti-competitive aspect.

Practical Takeaways

• PEMC and ERC share enforcement authority. Market participants facing investigation for WESM rule breaches may be subject to inquiry by either body, though PEMC typically handles initial breach investigations.
• The distinction matters. For anti-competitive behavior claims, the ERC takes the lead, and PEMC may only investigate if the ERC consents or fails to object within ten business days.
• Market participation agreements are binding. By joining the WESM and agreeing to its rules, participants voluntarily submit to PEMC's investigative and sanctioning powers.
• The ERC retains ultimate oversight. PEMC's sanctions do not prejudice the ERC's authority to impose fines and penalties under EPIRA, and PEMC must furnish the ERC copies of its investigations and conclusions.
• The 2008 protocol remains operative. The Court's ruling validates the memorandum of agreement and protocol that have governed the division of enforcement labor between PEMC and the ERC.
