TCN Announces Blackout in Three States Amid Critical Maintenance

TCN blackout Kogi – The Transmission Company of Nigeria (TCN) has announced a scheduled power outage affecting parts of Kogi, Edo and Ondo states. The blackout, set to begin on Monday, 16 September 2026, is part of an annual maintenance programme at the 330/132kV Ajaokuta Substation. TCN says the exercise is essential to prevent unplanned disruptions and to safeguard the Abuja Electricity Distribution Company (AEDC) and Benin Electricity Distribution Company (BEDC) networks. The TCN blackout Kogi underscores the importance of proactive infrastructure upgrades.

Why the TCN blackout Kogi maintenance matters for Nigeria’s grid

Nigeria’s power grid is a complex web of generation, transmission and distribution assets. The Ajaokuta Substation, located in Kogi State, is a critical node that links the northern and southern transmission corridors. Over the years, the substation has handled increasing load as new power plants come online and demand rises in urban centres such as Lagos, Abuja and Port Harcourt.

Annual maintenance is a standard industry practice worldwide. It involves cleaning, testing, and replacing ageing components like circuit breakers, transformers and protective relays. By carrying out these tasks during a controlled blackout, TCN aims to minimise the risk of sudden faults that could cascade into larger, uncontrolled outages across the national grid.

Energy experts note that well‑planned maintenance can improve system reliability by up to 15 % and extend the life of expensive infrastructure by several years. In a country where electricity access remains below 70 % of the population, keeping the backbone of the grid in good shape is a strategic priority.

What households and businesses should expect

Residents in the affected local government areas of Kogi, Edo and Ondo will experience a full‑load shedding schedule that lasts between six and twelve hours per day, depending on the specific feeder. TCN has advised consumers to:

• Plan essential activities such as cooking, studying and medical device usage around the outage windows.
• Charge mobile phones, laptops and other battery‑powered devices in advance.
• Use alternative power sources like inverters or generators, ensuring they are operated safely and in compliance with environmental regulations.

Businesses, especially those in manufacturing and agro‑processing, are urged to coordinate with their local distribution companies (AEDC or BEDC) to obtain detailed load‑shedding timetables. Some firms may opt to shift production to off‑peak hours or temporarily relocate critical processes to facilities with uninterrupted power supply (UPS) systems.

TCN has pledged to keep the public informed through its website, social media channels and SMS alerts. The company also assures that the outage will be limited to the three states and will not affect the national capital territory or the western corridor.

Impact on the broader power sector

While the immediate inconvenience is felt locally, the maintenance exercise has ripple effects across the entire sector. By ensuring the Ajaokuta Substation operates at peak efficiency, TCN helps stabilise voltage levels, reduces transmission losses and supports the integration of renewable energy projects that are increasingly being connected to the grid.

Renewable developers in the Niger Delta and northern states have welcomed the move, noting that a reliable transmission backbone is essential for the viability of solar and wind farms. Moreover, the maintenance aligns with the Federal Government’s 2026‑2028 Power Sector Roadmap, which targets a 30 % increase in grid capacity by 2030.

Analysts also point out that a well‑maintained grid can attract more private investment, especially from independent power producers (IPPs) looking to sell electricity under the Nigerian Electricity Market (NEM). The confidence boost could translate into faster project approvals and lower financing costs.

How the outage is being communicated

Effective communication is a cornerstone of any large‑scale outage plan. TCN has rolled out a multi‑channel strategy that includes:

1. Official press release on the Daily Post website (see source).
2. Live updates on the TCN Twitter handle @TCN_NG.
3. SMS alerts sent to registered customers in the affected districts.
4. Community outreach through local radio stations in Kogi, Edo and Ondo.

Feedback from the public so far has been mixed. While many appreciate the transparency, some community leaders have called for clearer timelines and compensation mechanisms for small traders who may lose revenue during the blackout.

Preparing for future outages

Power interruptions are a recurring reality in many African countries. To build resilience, households and businesses can adopt several best practices:

• Invest in solar home systems or mini‑grid solutions where feasible.
• Maintain regular servicing of generators to ensure fuel efficiency and lower emissions.
• Adopt energy‑saving habits such as using LED lighting and energy‑efficient appliances.
• Stay informed about scheduled maintenance by subscribing to utility newsletters.

Governments at state and federal levels are also exploring policies that encourage distributed generation and demand‑side management, which could reduce the overall reliance on centralized transmission assets.

FAQ

Q: When will the TCN blackout in Kogi, Edo and Ondo start and end?
A: The outage begins on Monday, 16 September 2026, and is expected to conclude by the end of the week, subject to successful completion of maintenance work.

Q: Will the blackout affect water supply or other utilities?
A: The maintenance is limited to electricity transmission. Water supply and other utilities should continue operating normally, though some pump stations that rely on electricity may experience brief interruptions.

Q: How can I receive real‑time updates about the load‑shedding schedule?
A: Register your mobile number with AEDC or BEDC for SMS alerts, follow TCN’s official Twitter account, and check the Daily Post article linked below.

Looking ahead

As Nigeria pushes towards greater electrification and a greener energy mix, scheduled maintenance like the one at Ajaokuta Substation will become a routine yet vital part of the power sector’s evolution. Stakeholders—from policymakers to end‑users—must continue to collaborate, ensuring that short‑term disruptions are managed effectively while long‑term reliability improves.
