The unbundling of the Philippine electricity sector under the Electric Power Industry Reform Act (EPIRA) has made the different components of electricity costs more visible to consumers. Unlike a vertically integrated system, where costs may be embedded in a single bundled rate, Philippine electricity bills separately identify generation, transmission, system loss, and other charges. This transparency has improved the visibility of electricity costs, but it has also made system loss a more prominent policy and political issue.

As system loss is explicitly itemized in electricity bills, its treatment directly affects affordability and public confidence in electricity pricing. The issue has therefore become part of the national debate on high electricity costs. In his fifth State of the Nation Address on July 27, 2026, President Ferdinand Marcos Jr. called on Congress to amend EPIRA and prohibit the passing on of system loss charges, including the associated value-added tax, to consumers.

Few consumers would object to lower electricity bills. However, system loss is not a single, uniform cost. Some losses are inherent in the physical operation of electricity networks. Others arise from preventable causes such as electricity pilferage, illegal connections, meter tampering, inaccurate metering, billing errors, and operational deficiencies. These losses have different causes and should not automatically be treated or recovered in the same manner.

Understanding Technical and Nontechnical Losses

A clear distinction between technical and nontechnical losses is essential to fair and effective regulation.

Technical losses occur naturally in the physical delivery of electricity. As electricity flows through conductors, transformers, and other network equipment, some energy is lost through electrical resistance and heat. Such losses are inherent in any functioning electricity system and cannot be completely eliminated.

However, unavoidable does not mean unmanageable. Technical losses can be reduced through efficient system design, proper maintenance, improved conductors and transformers, network optimization, better planning, and modern technologies. Utilities should therefore efficiently manage technical losses and continuously improve their performance.

By contrast, nontechnical losses are not caused by the physical characteristics of the network. They include electricity pilferage, illegal connections, meter tampering, inaccurate or faulty metering, unauthorized consumption, billing errors, and other administrative or operational failures. These losses are largely preventable, although addressing them may be complicated by poverty, informal settlements, enforcement limitations, and public safety concerns.

The distinction matters because consumers who pay their electricity bills should not automatically subsidize the electricity that others consume without paying or the costs resulting from preventable operational deficiencies. At the same time, utilities must have an incentive and the means to reduce losses, while regulators must be able to determine which costs are prudent, efficient, and justified.

These issues ultimately raise questions of fairness, accountability, and transparency—the basic principles of good governance.

The Regulatory Challenge

Electricity regulation must balance two legitimate objectives. Utilities must be able to recover prudent and efficient costs necessary to provide safe, reliable, and continuous service. Meanwhile, consumers should be protected from costs arising from inefficiency, inadequate controls, or preventable losses.

Technical losses may therefore be recognized as part of the legitimate cost of operating an electricity network. Their recovery should nevertheless be accompanied by clear expectations of continuous improvement. Utilities should manage losses efficiently and invest in measures that reduce them.

Nontechnical losses require stricter scrutiny. Automatically passing preventable losses to consumers can weaken the incentive to invest in loss prevention, improve metering, strengthen enforcement, and correct operational deficiencies. It can also undermine public confidence in the fairness of electricity rates.

Cost recovery should therefore be based on evidence. Utilities should report system losses transparently, distinguish technical from nontechnical losses, establish reasonable loss reduction targets, and demonstrate concrete efforts to meet them. Where preventable losses persist because of inadequate utility action, automatic recovery from consumers should not be the default.

This does not mean that distribution utilities (DUs) and electric cooperatives (ECs) can solve electricity pilferage on their own. Effective enforcement also requires regulators, local governments, law enforcement agencies, and communities. The regulatory framework should recognize these realities while maintaining clear accountability for losses within the control of the utility.

A Performance-Based Approach

A better framework should link system loss targets, utility performance, and cost recovery.

System loss targets should be based on network characteristics, historical performance, operating conditions, and relevant benchmarks. They should be transparent and periodically reviewed so that they remain realistic while encouraging continuous improvement.

Utility performance should then be measured against these targets using clear, verifiable indicators. Regulators should be able to determine whether a utility has taken reasonable steps to reduce losses, whether its performance is improving, and whether claimed costs are efficiently incurred.

Cost recovery should follow performance. Consumers should bear only the system loss costs that are consistent with prudent and efficient operations. Persistent underperformance, weak loss prevention efforts, or failure to address preventable losses should not automatically result in recoverable charges.

This approach provides stronger incentives for utilities to improve while protecting consumers from costs they should not have to bear. It also gives regulators a more objective basis for determining what costs are recoverable.

The Roles of the ERC and DOE

The Energy Regulatory Commission (ERC) has a central role in ensuring that electricity rates are just and reasonable. In system loss regulation, this role requires stronger disclosure, consistent methodologies, and a more rigorous evaluation of recovery claims.

The ERC should require standardized reporting that clearly separates technical and nontechnical losses across DUs and ECs, supported by auditable data and consistent loss classification protocols. Reported losses that exceed historical or benchmark ranges should automatically trigger regulatory review.

The ERC should also use performance-linked recovery caps so that avoidable or poorly justified losses are not treated as routine pass-through costs. Recovery above benchmark levels should depend on documented loss reduction programs, inspection results, and enforcement actions.

The Department of Energy (DOE), meanwhile, should ensure that system loss reform supports broader policies on energy efficiency, renewable energy, grid modernization, and technology adoption. Coordination between the DOE and ERC is important because the regulatory treatment of system losses should reinforce, rather than operate separately from, the modernization of the electricity system.

Modernization is Part of the Solution

Regulatory reform alone is insufficient to reduce system losses. Utilities need the infrastructure, data, and operational capabilities to identify problems and address them.

Distribution networks are becoming increasingly complex with the growth of renewable energy, rooftop solar, battery storage, electric vehicles, and other distributed energy resources. Traditional networks were designed primarily for one-way electricity flows from centralized generation to consumers. This model is changing as consumers increasingly become both users and producers of electricity.

This transformation requires greater visibility, flexibility, and control.

Investments in advanced metering infrastructure, digital monitoring, geographic information systems, distribution automation, and data analytics can improve network performance. They can help utilities detect unusual consumption, identify unauthorized connections, improve meter accuracy, strengthen billing systems, locate losses, and respond more quickly to operational problems.

To make these investments effective, utilities should focus modernization on the following approaches that directly identify, measure, and reduce losses:

• deploying tamper detection smart meters with remote disconnection capability where legally permissible;
• using feeder-level energy balance reconciliation systems;
• maintaining GIS-based maps of all service connections; and
• conducting periodic third-party technical audits in high-loss areas.

Rooftop solar deserves particular attention because it can reduce some technical losses by generating electricity close to the point of consumption, lowering the need for electricity to travel long distances through distribution networks. When paired with net metering, proper interconnection standards, and distribution planning, rooftop solar can also improve local resilience, reduce peak demand, support cleaner energy use, and provide consumers with a more active role in the modernization of the electricity system.

Beyond loss reduction, these investments improve reliability, outage management, renewable energy integration, and the data available for regulatory oversight.

This is consistent with the Electric Power Research Institute’s (EPRI) no-regrets approach to power system modernization: investments that improve today’s system while preparing it for future technologies, operating conditions, and uncertainties. EPRI describes its distribution work as a balanced, no-regrets approach to developing a modern distribution grid.

Where modernization investments are prudent, cost effective, and demonstrably beneficial to consumers, the regulatory framework should allow appropriate recovery. Such recovery, however, should be transparent and linked to measurable improvements in efficiency, reliability, service quality, or loss reduction.

A Broader Consumer Perspective

System loss reform should be part of a broader effort to make electricity more affordable. Generation costs, fuel prices, transmission charges, taxes, procurement practices, market rules, and other regulatory policies affect the final electricity bill. Removing or reducing system loss charges alone is insufficient to resolve the structural causes of high electricity prices.

Consumers also have a role in improving the efficiency of the electricity system. Households and businesses should practice energy conservation and efficiency and, where eligible, utilize programs such as net metering, retail competition and open access, retail aggregation, and time-of-use pricing.

Consumers can also help utilities address nontechnical losses by reporting electricity pilferage, illegal connections, meter tampering, and other forms of unauthorized consumption. A vigilant and informed consumer base can complement utility efforts and strengthen accountability.

Efficient electricity service has other benefits aside from reducing household budgets. Lower power costs could improve the country’s business competitiveness, investor appeal, job creation, and industrialization.

The Path Forward

System loss reform provides an opportunity to strengthen consumer protection, improve utility performance, and accelerate the modernization of the electricity sector.

The goal should not be to treat all system losses alike. Technical losses are an unavoidable part of electricity delivery and should be managed through continuous improvement and prudent investment. Nontechnical losses, particularly those arising from preventable causes, require strong accountability, enforcement, monitoring, and loss reduction measures.

The regulatory framework should therefore comprise the following:

1. Reformation of the recoverability of nontechnical losses

Nontechnical losses arising from pilferage, unauthorized consumption, and preventable operational failures should not automatically be passed on to consumers. The recovery process should include the following:

• submitting mandatory loss source attribution reports that distinguish technical from non-technical losses;
• requiring independent audit verification for high-loss utilities;
• applying performance-based recovery ceilings tied to historical best performance; and
• implementing a loss reduction action plan, which includes targeted inspections, meter replacement programs, and anti-pilferage drives, before any recovery is approved.

2. Strengthening of system loss reporting and performance evaluation

DUs and ECs should use standardized methodologies to report technical and nontechnical losses separately. System loss targets, performance indicators, corrective actions, and regulatory findings should be measurable, verifiable, and accessible to consumers. The ERC should also require the following:

• publishing quarterly feeder-level loss data;
• reconciling energy input and billed consumption; and
• disclosing enforcement outcomes, such as illegal connections detected and resolved.

3. Acceleration of grid modernization and digitalization

Advanced metering infrastructure, remote meter reading, meter data management, distribution automation, geographic information systems, and analytics should be prioritized, particularly in high-loss areas. The recovery of these investments should be allowed only when they are prudent, cost effective, and linked to measurable improvements.

Utilities should be required to submit technology deployment roadmaps with defined loss reduction targets, such as percentage reductions in nontechnical losses within three to five years, as a condition for cost recovery.

4. Strengthening of coordinated enforcement and community participation

DUs, ECs, the ERC, the DOE, local governments, law enforcement agencies, and communities should coordinate efforts against electricity theft, illegal connections, and meter tampering. Enforcement should be firm but fair, with appropriate safeguards for vulnerable households and due process. Mechanisms should include the following:

• forming joint inspection teams with LGUs and law enforcement;
• applying standardized penalties for repeat offenders; and
• operating community-based reporting hotlines with incentive schemes for verified reports of pilferage.

5. Consumer participation as part of the solution

Consumers should be encouraged to conserve energy, improve efficiency, participate in available market and distributed energy programs, and report electricity theft and other irregularities. Consumer empowerment should complement, not replace, utility accountability.

Utilities should also be required to implement consumer feedback systems that track complaints on billing accuracy, meter issues, and service irregularities, with mandatory resolution timelines.

Conclusion

System losses should not be treated as a single, undifferentiated cost that is automatically passed on to consumers. A fair and effective framework must distinguish unavoidable technical losses from preventable nontechnical losses, apply different standards to each, and make recovery conditional on evidence, performance, and regulatory discipline.

Good governance is the organizing principle. Fairness means consumers pay only for prudent and efficiently incurred costs; transparency means the basis for system loss charges is visible, verifiable, and open to scrutiny; and accountability means regulators enforce clear standards while DUs and ECs reduce losses within their control.

The system should not merely move costs from consumers to utilities but also reduce avoidable costs, reward efficient performance, and prevent weak controls from becoming recoverable charges.

An electricity sector governed this way will be more affordable for consumers, more disciplined for utilities, more credible for regulators, more competitive for business, and better prepared for the country’s transition to a modern, resilient, and cleaner power system.
