How GEBE determines load shedding: A closer look at the criteria

Load shedding, the intentional reduction of electricity supply to avoid overloading the power grid, is a critical practice employed by utility companies worldwide. In St. Martin, the ongoing energy crisis has necessitated frequent load shedding by NV GEBE. During a recent public forum, GEBE management outlined the criteria they use to determine which areas are subjected to load shedding. This article delves into these criteria to provide a clearer understanding of how decisions are made to maintain grid stability while minimizing the impact on the community.

Critical Infrastructure

One of the primary criteria for determining load shedding is the presence of critical infrastructure in certain areas. These are prioritized to remain online to avoid broader public health and safety issues.

  • Water Pumps: Areas with water pumps are crucial for ensuring a continuous water supply to the community. Shutting down these pumps can lead to significant disruptions and potential health hazards.
  • Hospitals: Medical facilities must remain operational to provide necessary healthcare services. Power outages in these areas could be life-threatening.
  • Police Stations: Law enforcement agencies need uninterrupted power to maintain public safety and order.

Example: Patrick Drijvers, a member of the management team, explained, “We have areas that have schools, we have pump stations, and I don’t think it’s ethical to even pull a cable that has pumps that deliver water to the people.”

Schools

Education is another priority during load shedding. NV GEBE aims to minimize disruptions to schools to ensure that students can continue their education without interruption.

  • School Hours: During school hours, typically from 7:30 AM until 1:00 PM, areas with schools are prioritized to remain online.
  • Educational Impact: Recognizing the importance of a stable learning environment, NVG EBE avoids load shedding in school areas during critical learning times.

Example: NV GEBE ensures that from 7:30 AM until 1:00 PM, areas with schools are not subjected to load shedding.

Load Demand

The current load demand on the grid is a crucial technical criterion for load shedding decisions. Areas with higher load may be targeted to quickly reduce the strain on the system and maintain overall grid stability.

  • High Load Areas: By identifying and shedding load in high-demand areas, NVG EBE can effectively manage the grid’s stability.
  • Dynamic Adjustments: Load shedding decisions are made based on real-time data and the immediate needs of the grid.

Example: NVG EBE’s power plant indicates to the distribution department which cables have the most load and need to be pulled to stabilize the grid.

Frequency and Impact

Certain protections and mechanisms at the power plant automatically select which cables to pull based on frequency and load to avoid system-wide blackouts.

  • Automated Protections: These protections help in making quick decisions to prevent larger outages.
  • Minimizing Impact: The goal is to stabilize the frequency and prevent cascading failures that could lead to more extensive power outages.

Example: The power plant has protection devices that select cables to be shed first to stabilize frequency.

Geographic Considerations

To ensure fairness and manage the impact on different regions, NV GEBE considers geographic factors and past load shedding patterns.

  • Fair Distribution: Areas that have been frequently affected by load shedding may be given respite to distribute the impact more evenly across different regions.
  • Rotational Load Shedding: This approach helps in spreading the burden of load shedding across various communities, preventing prolonged outages in any single area.

Example: There was an acknowledgment that some areas might get switched out multiple times, but this is managed as best as possible to distribute the impact.

NV GEBE’s criteria for load shedding reflect a balance between technical necessity and ethical considerations. By prioritizing critical infrastructure, educational institutions, and high-demand areas, the company aims to maintain grid stability while minimizing the impact on essential services. The use of automated protections and a focus on fair geographic distribution further demonstrate NVG EBE’s efforts to manage load shedding effectively.

As St. Martin continues to navigate its energy challenges, understanding these criteria can help the community appreciate the complexities involved in maintaining a stable and reliable power supply. While the immediate goal is to manage the current crisis, long-term solutions will require continued investment in infrastructure and collaborative efforts to build a more resilient energy system.

Technical and societal considerations

Balancing Power: should NV GEBE independently manage societal considerations in load shedding?

As St. Maarten grapples with an ongoing energy crisis, the practice of load shedding by NV GEBE has become a contentious issue. Load shedding involves the intentional reduction of electricity supply to prevent overloading the power grid. While NV GEBE has the technical expertise and mandate to manage grid stability and protect generators, the question arises: Should NV GEBE also have the sole authority to make decisions on societal considerations during load shedding, or should other stakeholders be involved?

Technical Considerations: NV GEBE’s mandate

NV GEBE holds the mandate to take immediate and effective measures to protect the grid and generators from overload. This technical responsibility includes:

  1. Ensuring Continuous Operation of Critical Infrastructure:
    • Water pumps, hospitals, and police stations are prioritized to remain operational, maintaining public health and safety.
  2. Managing Load Demand:
    • High-demand areas are targeted to reduce strain on the grid, maintaining overall stability.
  3. Utilizing Protection Devices:
    • Automated systems select cables for load shedding based on frequency and load, preventing system-wide blackouts.

These technical considerations are essential for maintaining the integrity of the power grid and ensuring the continuous delivery of electricity where it is most needed.

Societal Considerations in Load Shedding

However, load shedding also has significant societal implications, affecting daily life, education, and the economy. NV GEBE’s current approach includes:

  1. Prioritizing Schools:
    • Avoiding disruptions during school hours to provide a stable learning environment.
  2. Geographic Fairness:
    • Distributing the impact of load shedding evenly across different regions to prevent prolonged outages in any single area.

The Case for Independent Decision-Making by NV GEBE

Proponents argue that NV GEBE should have the sole authority to make decisions on societal considerations for several reasons:

  1. Efficiency and Speed:
    • NV GEBE’s ability to make quick decisions is crucial during crises. Involving multiple parties could slow down the decision-making process, potentially exacerbating the crisis.
  2. Expertise and Data:
    • NV GEBE has access to real-time data and technical expertise, enabling informed decisions that balance technical and societal needs effectively.

The Case for Involving Other Stakeholders

On the other hand, there are compelling reasons to involve other stakeholders in decisions related to societal considerations:

  1. Transparency and Public Trust:
    • Including public authorities and community representatives can enhance transparency and build trust, ensuring that the rationale behind load shedding decisions is clear and publicly available.
  2. Equity and Fairness:

Government and Other Key Facilities

One specific concern is the perceived immunity of government facilities from load shedding. Questions arise about whether these facilities have dedicated lines or emergency power supplies and whether other parties might benefit from such arrangements. If certain facilities enjoy uninterrupted power while others do not, it could create an unfair advantage, especially if they hold the same service contracts as everyone else.

  • Emergency Power Supplies: It is reasonable to expect that critical government facilities have backup power supplies to maintain operations during outages. However, the extent and capacity of these backups should be clarified to ensure transparency.
  • Dedicated Lines: If dedicated lines exist for certain facilities, this must be communicated clearly to prevent perceptions of favoritism and ensure all stakeholders understand the infrastructure realities.
  • Fair Distribution: Ensuring that no undue advantage is given to specific facilities or organizations is crucial. Any perceived disparity in load shedding practices must be addressed transparently.

A Hybrid Approach: Balancing Independence and Collaboration

Given the complexities involved, a hybrid approach may be the most effective solution. NV GEBE should retain the authority to make immediate decisions to protect the grid and generators, leveraging their technical expertise and real-time data. However, a framework for collaboration with public authorities and community representatives could be established to guide decisions on societal considerations. This framework could include:

  1. Regular Consultations:
    • Establishing a schedule for regular consultations with stakeholders to review load shedding plans and discuss societal impacts.
  2. Transparency Measures:
    • Implementing transparency measures, such as publicly sharing load shedding criteria and decision-making processes.
  3. Feedback Mechanisms:
    • Creating channels for community feedback to ensure that the voices of affected residents are heard and considered.

While NV GEBE has the technical mandate and expertise to make critical decisions for protecting the power grid, involving other stakeholders in decisions related to societal considerations can enhance transparency, fairness, and trust. A hybrid approach that balances NV GEBE’s independence with collaborative input from public authorities and community representatives can lead to more equitable and effective load shedding practices. This approach ensures that both technical and societal needs are met, fostering a more resilient and inclusive energy system for St. Maarten.
