National Grid Collapse: CEO Highlights Complex Causes
Uncovering the Real Reasons for Nigeria's Grid Collapse
“We have grid disturbances two times. The first one was on Monday, October 14th...”
Nigeria's Power Grid: CEO Abdulaziz Addresses Challenges. Learn about plans to upgrade infrastructure, tackle neglect, and ensure reliable energy supply.
Sule Abdulaziz, CEO of the Transmission Company of Nigeria (TCN), stresses that his organization shouldn't bear the brunt of blame for Nigeria's recurring national grid collapses. According to him, these collapses are often the result of a complex interplay of factors, including generation, transmission, and distribution system issues. Think of it like a supply chain - if one link breaks, the entire system can come crashing down.
Factors Contributing to Grid Collapses
Generation Issues: Problems with power plants or generators can reduce electricity supply, leading to grid instability.
Transmission System Glitches: Faulty transmission lines or equipment can disrupt electricity flow.
Distribution System Failures: Issues with substations, transformers, or distribution lines can cut off power to consumers.
Abdulaziz's stance highlights the need for a collaborative approach to addressing Nigeria's power challenges. By acknowledging the multifaceted nature of grid collapses, he's emphasizing that solving this problem requires input from various stakeholders, including generation and distribution companies.
“TCN is in charge of the grid but if there's a system collapse, it doesn't mean that all the problems are from TCN," Abdulaziz said.
“It can be from generation, it can be from transmission, and it can be from distribution. And some of these also can come as a disaster.”
Abdulaziz referenced the recent spate of grid failures, citing two significant disturbances within the past week.
“We have grid disturbances two times. The first one was on Monday, October 14 and the second one was on Saturday, October 21” he said.
Sule Abdulaziz, CEO of the Transmission Company of Nigeria, set the record straight - reports of another national grid collapse on Tuesday, October 15, were actually false. This clarification contradicts earlier claims that the grid suffered a second collapse just 15 hours after the initial one on Monday, October 14.
“There are some news that says that the grid collapsed again on Tuesday. That one is not correct.
“On Monday, we were trying to restore the grid, then we had some setback, and that is when we had to start all over again, but it wasn't a collapse.”
Sule Abdulaziz, the Managing Director of the Transmission Company of Nigeria (TCN), acknowledges that more needs to be done to prevent frequent grid collapses, but he also highlights the significant progress made since 2015. Essentially, Abdulaziz is saying that while there's still room for improvement, the TCN has made notable strides in stabilizing the national grid over the past few years.
Abdulaziz's statement comes as the TCN launches efforts to prevent grid collapses, including procuring spinning reserves to mitigate disruptions to the power supply. This move demonstrates the company's commitment to addressing the issue and ensuring a more reliable electricity supply for Nigerians.
Nigeria's power grid has experienced frequent collapses in the past, with 108 recorded incidents since the power sector was privatized. However, Abdulaziz's acknowledgment of the challenges and his emphasis on progress made signify a step in the right direction towards achieving a more stable power supply.
“There are some news that says that the grid collapsed again on Tuesday. That one is not correct.
“On Monday, we were trying to restore the grid, then we had some setback, and that is when we had to start all over again, but it wasn't a collapse.”
The TCN CEO emphasized the urgent requirement for significant investment in Nigeria's transmission infrastructure, which has suffered from years of neglect.
“But if you look at the records, the grid collapse has reduced from 2015. If you have all these records, you will see that from the year 2022, we spent over one and a half years, and there was no grid collapse. So we are doing our best.”
“We know we have to do more, but at least we are getting to know the issues and we are resolving them one by one” he added.
The TCN CEO emphasized the necessity for significant investment in Nigeria's transmission infrastructure, citing prolonged neglect.
“So, most of the equipment we are using, some of them are even 50 years old, some 40 years old. So it is not possible for those equipment to work perfectly,” Abdulaziz explained.
Investing in grid infrastructure shouldn't be a one-time thing; it needs to be an ongoing process. This is crucial for replacing outdated equipment, ensuring the grid stays up-to-date and functions smoothly. Think of it like maintaining a car - you need to keep replacing parts and upgrading systems to keep it running efficiently.
“Continuously, we build new substations, we buy spare parts and change some of the outdated equipment,” he said.
“You see, it cannot be done once. It is bit by bit.”
Abdulaziz highlighted that while some TCN projects receive federal budget funding, the majority of maintenance efforts are actually financed through internally generated revenue (IGR). This means that TCN relies heavily on its own revenue streams to keep the grid running smoothly.
In fact, TCN has been proactive in generating its own funds for critical equipment and maintenance materials, ensuring grid stability and reliability. They've even invited reputable companies to bid on procurement projects funded by TCN's IGR savings.
TCN has made significant progress in delivering outstanding projects, including the Nigeria Electricity Grid Maintenance, Expansion and Rehabilitation Program. However, despite these efforts, TCN still faces funding shortfalls, with a reported N637 billion deficit. This underscores the importance of exploring alternative funding sources to support TCN's maintenance and expansion efforts.
“Most of the funds we are using is from internally generated revenue. There are some projects that are sponsored from the federal budget, but most of the maintenance is carried out by IGR.”
Upgrading grid infrastructure is a massive undertaking that can't be done all at once. It's like trying to renovate an entire city in one day - impossible. The complexity of the power grid, combined with the need to balance supply and demand in real-time, makes it a significant challenge.
Think of it like this: grid operators face two major hurdles - network inadequacy and lack of real-time network management at low voltages. This can lead to network instability, affecting reliability standards and causing voltage instabilities, frequency inconsistency, and harmonic distortion of the power system.
To tackle this, grid operators need to rethink their planning approaches and tools to integrate renewable energy sources effectively. This might involve upgrading existing infrastructure, investing in new technologies, and adopting more flexible and resilient grid management systems.
Challenges:
Network Inadequacy: Not enough physical grid capacity to accommodate supply and demand connections.
Lack of Real-time Network Management: Insufficient management at low voltages, leading to network instability.
Integration of Renewable Energy Sources: Balancing supply and demand in real-time while incorporating renewable energy sources
It's clear that upgrading grid infrastructure is a complex, ongoing process that requires careful planning, coordination, and investment.
“So what we do every year is that we schedule some maintenance, changing some of the old equipment.”
