Electricity update: Energy supply rebounds as TCN restores collapsed power grid


Electricity supply in Nigeria rebounded on Sunday, April 10, 2022 after the shocking decline recorded on Saturday, when the country’s electricity supply collapsed by 47.3% to 37,440.1 MWh, the lowest level low since recovering from the collapse of the national grid in March.

However, on Sunday, energy emitted jumped 114.7% to 80,382.73 MWh, or 98.74% of the total 81,405.31 MWh generated. Despite the improved energy supply and production is still well below desired levels as Nigeria needs at least 105,000 MWh of daily supply.

Additionally, according to the data, which was obtained from the Transmission Company of Nigeria (TCN), power generation peaked at 3,658.8 MW, 11.5% higher than the 3,281.5 MW recorded on Saturday, while the lowest was 3,117.4 MW.


  • Peak generation – 3,658.8 MW (+11.5%)
  • Off-peak generation – 3,117.4 MW (+9,346%)
  • Energy generated – 81,405.31 MWh (+114.4%)
  • Energy emitted – 80,382.73 MWh (+114.7%)

Additionally, the highest frequency for the day was 50.82 Hz, while the lowest frequency was 49.14 Hz.

Why the power outage?

According to Energy Minister Aliyu Abubakar, the national grid collapsed following vandals, who disrupted the transmission tower between Akwa Ibom and Cross River states, leading to another power outage .

The network, which has collapsed several times this year, collapsed around 6:30 p.m. on Friday and crashed again around 8:30 p.m., causing power outages in many parts of the country.

Abubakar said:While a detailed investigation into the immediate and remote causes of the recurring grid outage is currently underway by the Nigerian Electricity Regulatory Commission and the system operator (the national grid operator), the process of Supply restoration is underway with some sections of the national grid already energized and supply restored for consumers.

“Following our previous press release, we would like to inform the general public that the immediate cause of the nationwide blackout (system collapse) was an act of vandalism to a transmission tower on the Odukpani – Ikot Ekpene dual circuit transmission line 330kV thus resulting in a sudden loss of about 400 MW of production, which consequently led to a cascade of closed factories across the country.

“We wish to advise the public that power to the grid is being restored sequentially by the system operator as other power plants on the grid are dispatched to cover lost generating capacity at the Calabar Power Plant owned by the Niger Power Holding Company Ltd.”

why it matters

Electricity is a basic need for many Nigerians and their businesses, especially given the skyrocketing price of diesel and the recent fuel shortage across the country.

  • The resumption of some normality in the electricity supply will go a long way in serving as a relief to the Nigerian people.
