GenCos struggle to sustain output as DisCos blame low system frequency and load shedding…
The recent decline in electricity supply across Nigeria has been linked to gas supply constraints affecting the performance and operational capacity of power generating companies (GenCos).
The disclosure was made in a post by Nigeria National Grid, an electricity system information page on X (formerly Twitter), on Tuesday, December 16, 2025.
According to the post, inadequate gas supply has reduced the ability of GenCos to operate at optimal levels, resulting in lower generation output and disruptions to grid stability nationwide.
“Major reason for drop in power supply nationwide: GenCos are experiencing gas supply constraints affecting their optimal output and general operational frequency,” the post stated.
Nigeria National Grid serves as an information platform that provides updates on grid conditions and system disturbances from the perspective of the Transmission Company of Nigeria (TCN), although it does not own or operate the national grid.
EEDC confirms impact in South-East
The Enugu Electricity Distribution Company (EEDC) Plc has also confirmed that customers across the South-East are experiencing reduced power supply due to the same gas-related challenges affecting electricity generation nationwide.
In a statement signed by its Group Head, Corporate Communications, Emeka Ezeh, EEDC explained that low system frequency, caused by inadequate gas supply to GenCos, forced the TCN to implement load shedding, thereby reducing power allocations to distribution companies.
The development, EEDC said, has significantly affected the volume of electricity available to its franchise areas and disrupted daily power supply to customers served by its subsidiary firms, MainPower, TransPower, FirstPower, NewEra and EastLand.
“Low system frequency occasioned by gas constraints affecting the Generation Companies has necessitated load shedding of available energy by the Transmission Company of Nigeria,” the statement said.
EEDC added that industry stakeholders are working to resolve the challenge and restore stable electricity distribution, while apologising to customers for the inconvenience caused.
PHED reports similar challenges
Similarly, the Port Harcourt Electricity Distribution Plc (PHED) has attributed the ongoing load shedding in its coverage areas to poor generation and low allocation from power producers.
PHED said the situation has affected all its franchise areas, which include Rivers, Bayelsa, Cross River and Akwa Ibom states.
“Kindly be informed that the current load shedding being experienced across our franchise areas is a result of poor generation and allocation from the generating companies,” PHED stated, while appealing to customers for patience as efforts are underway to improve supply.
Background
Electricity consumers across several parts of the country have raised concerns over worsening power supply in recent days, with reports of prolonged outages and inconsistent service.
Nigeria’s power sector continues to face persistent gas supply challenges driven by inadequate infrastructure, security issues in gas-producing regions, weak commercial arrangements, low domestic gas pricing that discourages investment, and unresolved payment and subsidy concerns.
Despite Nigeria’s vast gas reserves, these challenges have limited gas availability for thermal power plants, leading to frequent blackouts, unstable grid operations and increased pressure on electricity distribution companies.
