Reform of NERSA— A Comprehensive Approach

Introduction

The National Energy Regulator of South Africa (NERSA) is supposed to play a pivotal role in overseeing the electricity sector, ensuring compliance with national standards, and protecting consumer rights. Among its responsibilities is the management of customer complaints, particularly concerning power quality.

Poor power quality can lead to significant inconveniences and financial losses for consumers, necessitating a robust framework for addressing these issues.

This article underscores the pressing need for reform within the National Energy Regulator of South Africa (NERSA), especially concerning its management of customer complaints related to poor power quality, as specified in NRS 048. Currently, NERSA faces significant challenges in addressing these complaints effectively, which has raised concerns among consumers about the reliability of their electricity supply.

Moreover, NERSA’s capacity to conduct thorough investigations and audits appears to be hampered, limiting its ability to hold power producers and distributors accountable for service quality. This lack of oversight not only affects customer satisfaction but also undermines the overall integrity of the electricity sector in South Africa.

It remains uncertain whether NERSA has ever conducted any audits or inspections, either with or without the necessary permissions. Further clarity on their auditing practices and adherence to regulatory protocols would be beneficial for transparency and accountability.

Enhancing NERSA’s Role in Consumer Protection and Power Quality in South Africa

Reforming NERSA is crucial for enhancing its responsiveness to consumer needs and ensuring effective enforcement of national standards. By improving its complaint handling processes and strengthening investigative capabilities, NERSA can better protect consumer rights and promote higher service standards across the industry. These changes are essential for building public trust and fostering a more reliable and efficient energy sector in the country.

Based on my experiences, I have significant concerns about NERSA’s effectiveness in enforcing these standards. When utility companies consistently fail to provide reliable service and violate regulatory requirements, the question arises: will NERSA impose meaningful penalties, such as fines or revoking operating licenses? Since 2010, my observations suggest a troubling lack of enforcement, casting doubt on NERSA’s commitment to safeguarding consumer interests.

To address these shortcomings, a comprehensive reform of the regulatory framework governing the electricity sector is essential. One of the most evident signs of the urgent need for Power Sector Regulatory Reform is the persistent issue of load-shedding. Had there been an effective regulatory body conducting regular investigations and audits, deficiencies in maintenance and the lack of investment in new infrastructure would likely have been identified before load-shedding became a significant problem. During these crises, many wondered, “How could this have gone unpredicted?” This raises important questions about NERSA’s role in allowing this situation to develop, with the answer not solely residing in rising tariff increases.

A key recommendation is to conduct independent investigations and audits to address the various issues affecting power quality and service delivery in the electricity sector. These assessments should be thorough, scrutinizing both the technical components of power supply and the operational practices and customer service protocols governing electricity generation and distribution.

Oversight should extend beyond local power distributors and private generating companies to include Eskom, the primary state-owned utility. Given Eskom’s significant role in the energy landscape, it is crucial that its operations are subject to the same level of scrutiny to ensure accountability and performance across the board. Engaging external bodies for these independent investigations can help identify systemic issues contributing to power quality problems, such as inadequate infrastructure, maintenance deficiencies, and lapses in regulatory compliance. By illuminating these areas, NERSA can develop targeted strategies to rectify them, ensuring that all power producers and distributors, including Eskom, adhere to national standards.

Moreover, these audits should actively involve stakeholders, including consumers, to gather valuable insights and feedback on their experiences. This participatory approach can provide a more comprehensive understanding of the challenges faced by consumers, enabling NERSA to prioritize critical areas for improvement effectively.

Ultimately, implementing independent investigations and audits will enhance accountability within the electricity sector, foster a culture of transparency, and lead to more reliable electricity services for all South Africans. By addressing these issues directly, NERSA can significantly improve overall power quality and elevate customer satisfaction. This proactive approach will benefit consumers and strengthen the entire energy framework, paving the way for a more resilient and efficient electricity system.

It is critical that individuals appointed to oversight positions possess the necessary skills and experience to ensure that accountability and effective monitoring become the norm in the sector. Furthermore, mechanisms for penalizing local power producers and distributors for non-compliance must be established. Clear penalties for failure to meet service standards are essential for promoting accountability, which could include financial penalties, mandatory performance improvement plans, or even license suspensions in severe cases.

Regular audits should also be a cornerstone of the regulatory process. By conducting routine assessments of power quality and service delivery, NERSA can identify issues before they escalate, fostering a culture of continuous improvement. These audits should be transparent and publicly available, enabling consumers to hold power providers accountable for their service levels.

Reforming NERSA’s approach to regulatory enforcement and customer complaints is not merely an administrative necessity; it is a critical step toward ensuring reliable power quality in South Africa. By establishing a robust oversight framework, imposing effective penalties, and instituting regular audits, we can enhance accountability and ultimately improve the service experienced by consumers.

Understanding NRS 048 and Its Significance

NRS 048 outlines the standards for electricity supply quality, including voltage levels, frequency stability, and other essential parameters that ensure reliable service.

This approach ensures that auditors concentrate on high-impact areas, thereby improving overall efficiency.
  2. Implement Comprehensive Internal Controls: A robust internal control system is essential for effective auditing. Best practices suggest that Local Power Distributors should establish controls over financial reporting, asset management, and service delivery. For instance, the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework can be utilized to develop comprehensive internal control measures. Regularly assessing these controls helps in identifying weaknesses that could lead to errors or fraud.
  3. Enhance Transparency and Accountability: Auditing practices should promote transparency in operations. Implementing standardized reporting formats and making audit results publicly accessible can foster accountability. The Global Reporting Initiative (GRI) emphasizes transparency in reporting, which can enhance stakeholder trust and ensure that power distributors are held accountable for their operations.
  4. Utilize Technology and Data Analytics: Incorporating technology into the audit process can significantly enhance accuracy and efficiency. Data analytics can help auditors identify trends and anomalies in usage patterns, billing, and financial statements. For example, the use of continuous auditing tools, as seen in multinational corporations, allows for real-time monitoring of transactions, enabling prompt detection of irregularities.
  5. Training and Development of Auditors: Continuous professional development for auditors is crucial. Local Power Distributors should invest in training programs that cover the latest auditing standards, regulatory changes, and technological advancements. The Association of Chartered Certified Accountants (ACCA) offers various resources and training that can equip auditors with the necessary skills to perform effective audits.
  6. Engagement with Stakeholders: Regular engagement with stakeholders, including customers, regulatory bodies, and employees, can provide valuable insights into areas requiring audit focus. For instance, conducting surveys or holding public forums can help identify concerns from the community, which can then be addressed during the audit process.
  7. External Audit Collaboration: Collaborating with external auditors can bring in additional expertise and impartiality to the audit process. Leveraging the knowledge and experience of firms that specialize in energy sector audits, can enhance the audit’s credibility and thoroughness.

Implementing these best practices can significantly enhance the auditing processes at Local Power Distributors, leading to improved operational efficiency, compliance, and stakeholder trust.

Conclusion

Reforming NERSA is crucial for effective electricity regulation and compliance. Integrating NERSA into an existing Chapter 9 institution, such as the Auditor General, could address some deficiencies—like improving audit capabilities and regulatory compliance—but it may not resolve all the inefficiencies and challenges currently faced by or with NERSA. A comprehensive approach to reform is needed to streamline its operations.

While this integration might not directly address customer complaints about poor power quality in South Africa, it could enhance NERSA’s ability to access power producers and distributors for thorough investigations and audits.

By establishing a robust complaint management system, enhancing accountability among local distributors, enforcing clear penalties for non-compliance with NRS 048, and conducting regular audits, NERSA—or this new entity—can foster a more responsive and responsible regulatory environment.

These reforms must address not only immediate customer concerns but also foster long-term improvements in power quality and service reliability. It’s crucial that NERSA evolves alongside the changing energy landscape, actively engaging with and adapting to new challenges rather than remaining a passive observer.

Currently, it seems that power producers and distributors operate with minimal accountability, often acting without fear of consequences. This approach can undermine trust and lead to persistent issues for consumers. By taking a more proactive stance, NERSA can implement regulations that hold these entities accountable, ensuring they prioritize service quality and reliability.

Long-term improvements will require a framework that promotes transparency, encourages compliance, and facilitates collaboration between NERSA, power producers, and distributors. This way, NERSA can not only resolve immediate complaints but also establish a sustainable and responsive regulatory environment that benefits all stakeholders involved.

In this proposed structure, NERSA should operate strictly within the mandate assigned to it by relevant laws and regulations, ensuring it fulfills its foundational purpose: overseeing the electricity sector, enforcing compliance with national standards, and safeguarding consumer rights. It is essential for NERSA to maintain impartiality and remain insulated from external influences that could compromise its integrity.

Upholding NERSA’s independence, dignity, and effectiveness is vital. No individual or government entity should be allowed to interfere with its operations, allowing it to function without bias or pressure. This autonomy is crucial for building public trust and ensuring that NERSA can act in the best interest of consumers and the energy sector.

Moreover, NERSA must remain accountable to the public by providing regular, transparent reports on its activities and performance. This transparency should extend to audits and investigations, which should be made available online for public scrutiny. By doing so, NERSA can demonstrate its commitment to accountability and foster greater confidence in its role as a regulator. This approach not only reinforces its legitimacy but also empowers consumers by keeping them informed about how their interests are being protected and promoted.

The Challenges in Managing South Africa’s Electricity Sector

The National Energy Regulator of South Africa (NERSA) has faced significant criticism for its handling of the country’s electricity sector. Established to regulate the electricity, piped-gas, and petroleum pipelines industries, NERSA’s mandate includes ensuring a reliable and efficient energy supply. However, its performance has been underwhelming, leading to widespread dissatisfaction amid South Africa’s ongoing electricity crisis.

Inconsistent Tariff Decisions

One of the primary issues with NERSA’s management is its inconsistent tariff decisions. The regulator has been criticized for approving substantial tariff increases for Eskom, the state-owned electricity supplier, despite the utility’s ongoing operational inefficiencies and financial troubles. These increases have placed a heavy burden on consumers and businesses, exacerbating economic challenges in a country already grappling with high unemployment and slow growth.

Lack of Transparency

Transparency is a cornerstone of effective regulation, yet NERSA has often been accused of lacking openness in its decision-making processes. Stakeholders, including industry experts and consumer advocacy groups, have raised concerns about the opaque nature of NERSA’s operations. This lack of transparency undermines public trust and makes it difficult to hold the regulator accountable for its actions.

Failure to Address Load Shedding

Load shedding, or rolling blackouts, has become a persistent issue in South Africa, severely impacting daily life and economic productivity. NERSA’s inability to effectively address this problem has been a major point of contention. Despite numerous promises and plans, the regulator has failed to implement sustainable solutions to stabilize the electricity supply. This ongoing crisis highlights NERSA’s shortcomings in strategic planning and crisis management.

Regulatory Capture

There are also allegations of regulatory capture, where NERSA is perceived to be more aligned with the interests of Eskom than with those of the public. This perception is fueled by decisions that seem to favor the utility’s financial recovery over the broader need for a reliable and affordable electricity supply. Such actions have led to questions about the regulator’s independence and its ability to act in the public interest.

Public Trust and Transparency

Public trust in NERSA has also been eroded by perceptions of corruption and mismanagement. Allegations of favoritism and lack of transparency in decision-making processes have led to growing skepticism among stakeholders regarding the regulator’s integrity and capability. This distrust complicates collaboration between NERSA, Eskom, and independent power producers, which is essential for a cohesive and forward-looking energy strategy.

Personal Concerns About Transparency and Trust

Since I first lodged a complaint with NERSA regarding “Poor Service from City Power Johannesburg” on April 15, 2024, there has been little meaningful progress on this issue. Despite my persistent efforts to highlight these concerns, I only received a response on September 11, 2024, stating that an escalation letter had been drafted and was awaiting final signatures.

After following up on September 18, I was informed that the letter had indeed been sent. However, when I requested a copy of this correspondence, I was told that the legal department needed to provide guidance on whether such documents could be shared with complainants. Since that time, I have not received any further updates, which raises significant concerns about the transparency of this process. This situation feels unproductive and has left me with the impression that we are going in circles without achieving any meaningful progress.

Given the slow response and apparent lack of serious engagement, I can’t help but feel that my concerns are being disregarded. The unresolved issues regarding the imbalanced networks require thorough investigation and prompt action, as they directly impact the reliability of electricity supply in our community. It is essential that these matters are addressed swiftly and transparently to restore trust in the process.

Impact on Renewable Energy

South Africa has significant potential for renewable energy, yet NERSA’s regulatory framework has been criticized for not doing enough to promote and integrate renewable sources into the national grid. The slow pace of renewable energy adoption is seen as a missed opportunity to diversify the energy mix and reduce reliance on coal, which is both environmentally damaging and increasingly costly.

Conclusion

NERSA’s management of South Africa’s electricity sector has been marked by inconsistency, lack of transparency, and failure to address critical issues like load shedding. These shortcomings have not only eroded public trust but also hindered the country’s economic and social development. For South Africa to achieve a stable and sustainable energy future, significant reforms in NERSA’s regulatory approach are essential.

NERSA’s Role in the Electricity Sector: A Critical Examination

Introduction

The National Energy Regulator of South Africa (NERSA) plays a pivotal role in regulating and overseeing the electricity industry. However, recent events and historical practices raise questions about the effectiveness of NERSA’s mandate. In this blog post, we delve into NERSA’s licensing process, tariff approvals, and complaint handling.

Licensing Challenges

NERSA’s primary responsibility includes issuing licenses to power distribution and generation companies. Unfortunately, recent incidents suggest that this process isn’t without flaws. A newspaper article highlighted NERSA’s reluctance to grant access to decision records, leading to legal battles with organizations like OUTA. The regulator’s last-minute settlement offer further raises concerns about transparency and due diligence.

Tariff Approval Quandary

When it comes to approving electricity tariffs, NERSA faces another hurdle. Afriforum, a civil rights organization, filed an urgent legal application to prevent municipalities from increasing tariffs without proper cost studies. The High Court’s ruling in 2022 declared NERSA’s old method—relying on previous years’ tariffs—unlawful. The Electricity Regulation Act mandates cost-based adjustments, considering all relevant factors. Yet, NERSA shifted the responsibility to municipalities, potentially compromising fair tariff assessments.

Complaint Handling: A Mixed Bag

NERSA provides an avenue for anyone to submit complaints. However, the effectiveness of this process remains questionable. Consider a past complaint that led to a meeting in 2010. Despite acknowledging the need for action, the subsequent lack of feedback raises doubts about NERSA’s follow-through. Transparency and accountability are crucial for building public trust.

Urgent Matters: Unbalanced Currents and Voltages

On May 25, 2024, I raised a critical issue with NERSA—an alarming condition of unbalanced voltage and current. Urgent attention is necessary to ensure the safety and reliability of our electrical infrastructure. However, my interactions with NERSA representatives have left me skeptical. Their brief email responses may not suffice for thorough investigations.

Conclusion

As someone deeply entrenched in the electricity sector, I find it challenging to see NERSA’s significant impact. To truly enhance the sector’s performance, NERSA must address licensing inefficiencies, improve tariff approval processes, and prioritize robust complaint handling. Our collective energy future depends on it.

Who Gains Advantage from Unbalanced Network Conditions?

What could possibly prompt Eskom or any power distribution companies to look into issues of unbalanced power networks? Could it be the threat of legal proceedings?

I understood that a representative from Eskom was notified about potential network imbalances at the Modderbee municipal substation, but it might have been disregarded as unlikely. However, since I was not present, I cannot vouch for the accuracy of the information I received indirectly.

The secondary reason for publishing this article is my effort to reach out to someone who professes to have extensive knowledge about Eskom’s power quality. I did not just send one email, but two. Despite being successfully delivered, the first email went unanswered, and the second was “deleted without being read,” as per the notification I received in my email account.

Consider the recent increase in reported issues with cables and transformers, and then draw your own conclusions: Are Eskom and other power suppliers aware of the network imbalances? Moreover, do they implement sufficient checks to identify these issues in the networks? From what I’ve observed, it doesn’t seem so. They seem to ignore any alerts related to network imbalances.

A question that often arises is: who benefits from the extra costs that customers incur due to unbalanced network voltage conditions? Let us explore this. Customers need a specific amount of electrical power, also known as real power, to perform certain tasks. However, the unbalanced network conditions result in a significant increase in inefficient powers, leading to a rise in apparent power. As customers’ bills are mainly calculated based on this apparent power, they end up paying more for these inefficient powers. On the generation side, power must be produced to also compensate for the losses. Each unit generated carries a profit margin. Hence, the more units produced, the higher the profits. It is crucial to remember that all power plants, whether they are coal-fired, nuclear, or renewable, do not operate as non-profit organizations.

It’s also important to note that network imbalances are not easily noticeable in power supplies. For example, in Linden, people might believe the power supply is working properly by examining the phase-to-neutral voltages. Likewise, in Modderbee, officials from Eskom and the electricity department might view the network as free of issues when they see that the phase-to-phase voltages are stable.

If you think that living in a different part of the world protects you from unbalanced network conditions, it may be beneficial to reevaluate that belief. As highlighted in this document, you might be completely oblivious to such events.

Power Networks in Flux – Balancing the Unbalanced

Unbalanced network conditions in power supplies can be deceptive because phase-to-neutral voltage measurements might not reveal the full picture. Here are why phase-to-phase voltages might not be close to each other even if phase-to-neutral voltages are:

  1. Unmatched Impedance: If the impedance in the transformer banks is unmatched, it can cause unbalanced conditions that are not apparent in phase-to-neutral measurements but will affect phase-to-phase voltages.
  2. Large Single-Phase Loads: When large single-phase loads are unevenly distributed across a three-phase network, it can create an imbalance that affects phase-to-phase voltages.
  3. Generation Faults: Faults in power generation can lead to unbalanced conditions that might not be detected by measuring phase-to-neutral voltages alone.

In the case of Linden and Modderbee, officials may overlook unbalanced conditions by only considering phase-to-neutral or phase-to-phase voltages. It is crucial to measure both to get an accurate assessment of the power supply’s balance. Unbalanced conditions can lead to equipment damage, increased network losses, and inefficiencies. Therefore, comprehensive measurements and analysis are necessary to ensure the reliability and safety of the power supply.

To determine if you are paying too much for electricity, you can indeed perform a simple check using a clip-on ammeter and a voltmeter to calculate the apparent power in volt-amperes (VA). Here is how you can do it:

  1. Measure the Current (I): Use the clip-on ammeter to measure the current flowing through the circuit.
  2. Measure the Voltage (V): Use the voltmeter to measure the voltage across the circuit.
  3. Calculate Apparent Power (S): Multiply the current by the voltage to get the apparent power in VA.
  4. Determine the Cost: Multiply the apparent power by the tariff rate provided by your electricity supplier.

This method gives you an instantaneous reading of your power usage, which you can compare with your electricity bill to see if there is a significant discrepancy. If you suspect your meter is faulty, having it tested is a good option despite the initial cost which would likely be refunded if the meter is indeed faulty. Regular monitoring of your power usage can help you identify any inconsistencies or potential overcharges on your electricity bill.

To accurately determine if you are being overcharged for electricity, it is essential to consider the following assumptions:

  1. Constant Current and Voltage: The assumption that current and voltage remain constant is a simplification for calculation purposes. These can fluctuate due to various factors such as appliance usage and utility supply stability.
    • Perfect Power Supply: Assuming a perfect power supply without any fluctuations is an ideal scenario often used in theoretical calculations but not typically found in residential settings.
  2. Synchronized Timing: Starting the measurement process at the same time as the meter reading ensures that the comparison is based on the same usage period, which is crucial for accuracy.
  3. Meter Accuracy: It’s assumed that the meter is accurately measuring the power consumption without any faults or errors.
  4. No Unauthorized Usage: This assumption implies that there is no electricity theft or unauthorized usage being recorded on your meter.
  5. No Additional Charges: It’s assumed that the bill reflects only the cost of electricity consumed, without any additional fees or charges that could affect the total amount due.

By carefully considering these assumptions and comparing your actual power usage with the billed amount, you can determine if there is a discrepancy. If you suspect an error, it may be necessary to have your meter tested or to consult with your electricity provider for clarification. Remember, the accuracy of your determination is contingent upon the validity of these assumptions. If any of these assumptions do not hold true, the conclusion drawn about overcharging may not be reliable. These assumptions are necessary for a simplified calculation, but they do not reflect the complexities of actual power usage and supply conditions. For a more accurate assessment, a continuous recording of power consumption over the billing period, accounting for fluctuations, would be required. This data could then be compared with the meter reading on your bill to determine if there is a discrepancy indicating you might be paying too much for electricity. If such a discrepancy is found, it would be advisable to have your meter tested. Remember, the cost of testing the meter is typically refunded if the meter is found to be faulty.

Unbalanced voltage conditions in power supplies can indeed have significant effects, even if they are not immediately obvious. Let us explore why phase-to-phase voltages might not be relatively close to each other, despite phase-to-neutral voltages appearing balanced.

  1. Voltage Imbalance and Its Causes:
    • Voltage imbalance occurs when the voltages in a three-phase system are not equal. It can result from various factors:
      • Generation Faults: Issues in the power generation process can lead to voltage imbalances.
      • Unmatched Impedance: Transformer banks with unmatched impedance can cause imbalances.
      • Single-Phase Loads: Unevenly distributed single-phase loads across the three phases can create voltage imbalances. For example:
        • If one phase carries significantly more current due to single-phase motors or heating/cooling loads, the line-to-neutral voltage of that phase will be lower than the other two.
        • Similarly, if most of the load is connected over only two phases, one line-to-neutral voltage will be higher than the other two.
      • Unbalanced voltage affects both induction motors and electronic rectifiers.
  1. Effects on Induction Motors:
    • Motor Torque and Speed: Unbalanced voltage negatively impacts motor torque and speed.
    • Noise: Motors may produce excessive noise.
    • Current Imbalance: Voltage imbalance can lead to increased current imbalance.
    • Temperature Rise: The temperature rise due to voltage imbalance can be much greater than the percentage of imbalance itself.
  2. Why Phase-to-Phase Voltages May Differ:
    • Even if phase-to-neutral voltages appear balanced, phase-to-phase voltages can differ due to the specific load distribution.
    • Consider a scenario where:
      • Phase A has a higher load (more single-phase devices connected).
      • Phase B and C have relatively lower loads.
    • In this case:
      • The line-to-neutral voltage of Phase A will be lower.
      • The line-to-line voltages (Phase A-B and Phase A-C) will also differ.
    • Thus, phase-to-phase voltages may not be close to each other, even when phase-to-neutral voltages seem balanced.
  3. Practical Implications:
    • Unbalanced voltages can lead to equipment damage, motor inefficiencies, and increased network losses.
    • Monitoring phase-to-phase voltages is crucial to identify and address voltage imbalances.

Remember that maintaining balanced voltages across all three phases is essential for a stable and efficient power supply. If you encounter unbalanced conditions, further investigation is necessary to ensure the health of your electrical system.

A deep understanding of the complexities involved in electrical power systems and the importance of accurate billing are based on the actual power consumption. Concerns should be raised about the potential discrepancies in power distribution and billing, especially in the context of an unbalanced network where inefficiencies can lead to increased apparent power and potentially higher charges for consumers.

Here is a brief overview of the power types:

  • Real Power (P): This is the power that performs work in the circuit, such as running appliances or lighting. It is measured in watts (W) and is what consumers ideally should be billed for.
  • Reactive Power (Q): This power does not perform any real work; instead, it is used to maintain the electric and magnetic fields in inductive and capacitive loads. It is measured in volt-amperes reactive (VAR).
  • Apparent Power (S): This is the combination of real and reactive power and represents the total power supplied to the circuit. It is measured in volt-amperes (VA).

The relationship between these types of power can be represented by the formula:

In a perfectly balanced system, the real power would equal the apparent power, and there would be no reactive power. However, in practical systems, especially those that are unbalanced, the apparent power is typically higher due to the presence of reactive power.

If you are being billed solely on apparent power, it is possible that you are paying not only for the real power consumed but also for the inefficiencies of the system.

Contravention of Fiduciary Duties

On the 2nd of October 2023, I published an article with the heading “Phase Imbalance in Distribution Networks” in which I stated that “In a recent unrelated “survey”, I came across a 10-minute averaged voltage unbalance of 327% between Phase 2 and Phase 1”. I also asked the question: is Eskom aware what is happening on the Distribution and Reticulation Networks? I also stated that, since the medium-voltage supply comes directly from an Eskom substation which is probably about 20-metres away, one wonders what is going on at the Eskom substation since it is highly unlikely that the voltage unbalance is as a result faulty equipment at the municipal substation. It is as if one phase is completely missing. The same “missing” phase also show an abnormal high current. The neutral current which is supposed to be at or close to zero is also very high.

In a recent webinar, I posted a question about power quality disturbances. I was then told about the large number of Quality of Supply Instrument that Eskom have installed, assuming that it is regularly maintained and monitored so that poor power quality issues will be detected almost immediately, and action taken to rectify whatever may be causing the issue or issues.

Last week, I reached out to someone at Eskom I believe may be able to help me to have this situation investigated or refer me to someone who can assist me, but that email remained unanswered and the email I sent this morning, “was deleted without being read”. This person’s name appears to be involved in this type of work on the behalf of Eskom, and that is why I reached out to him. So, my question now is: do Eskom or any of the Power Distributors care about Poor Quality of Supply?
