The recent drop in power supply across the country has been attributed to gas supply constraints affecting the optimal output and general operational frequency of the generating companies (GenCos).
Okay News reports that this disclosure is contained in a post by Nigeria National Grid on its official X (formerly Twitter) account on Tuesday, December 16, 2025. The Nigeria National Grid (@NationalGridNg) serves as an information hub for grid status updates, often reporting on collapses and system disturbances from the perspective of Transmission Company of Nigeria (TCN).
The post stated that GenCos are experiencing gas supply constraints affecting their optimal output and general operational frequency across the nation.
South-East Region Hit Hard
Meanwhile, the Enugu Electricity Distribution Company (EEDC) Plc has stated that the recent decline in electricity supply across the South-East region was due to gas supply constraints affecting power generation nationwide. In a statement signed by its Group Head of Corporate Communications, Emeka Ezeh, EEDC said low system frequency, caused by inadequate gas supply to Generation Companies, forced the TCN to implement load shedding.
This development led to reduced power allocation to distribution companies across the country. EEDC noted that the situation has directly affected the volume of electricity available to EEDC and the quality of daily power supply to customers served by its subsidiary companies—MainPower, TransPower, FirstPower, NewEra and EastLand.
The electricity distribution company explained that efforts are currently being made by critical stakeholders in the electricity supply industry to address this challenge and restore normal power distribution. EEDC, however, apologised to customers for the inconvenience caused by the outages and appealed for patience and understanding as efforts continue to stabilise the system.
South-South Also Affected
Also, the Port Harcourt Electricity Distribution Plc (PHED) had blamed the current load shedding being experienced by its customers on poor generation and allocation from GenCos and the Nigerian Control Centre (NCC). The company stated that the current load shedding being experienced in all their franchise areas is a result of poor generation and allocation from the generating company and NCC.
PHED appealed to its esteemed customers to exercise patience as GENCO team is working assiduously to improve generation and allocation. PHED is a private electric distributor that provides power for Rivers, Bayelsa, Cross River and Akwa Ibom states.
There have been complaints by electricity consumers from various parts of the country over worsening power supply, with many residents reporting prolonged outages in recent days. Nigeria’s power companies have been facing major gas supply issues due to poor infrastructure, security problems, weak contracts (lack of ‘take-or-pay’), low domestic gas prices discouraging investment, and payment/subsidy issues.
This is despite vast gas reserves, leading to insufficient gas for thermal plants, constant blackouts, and jeopardized project financing across the electricity sector.
