Grid Generation Hits New Low As Gas Shortage Worsens

The Nigerian Independent System Operator (NISO) has warned of a sharp decline in electricity generation on the national grid, blaming persistent gas supply shortages that have forced thermal power plants to operate at just 40% capacity.

NISO said that as of 5:00 a.m. on Thursday, March 5, 2026, total generation stood at 3,940.53 megawatts (MW)—already below expected levels due to gas limitations hitting multiple generating stations.

The operator further stated that the situation worsened between 6:00 a.m. and 8:00 a.m., when several units shut down from inadequate gas, slashing available generation by about 292 MW.
Operational data from March 4 showed thermal plants need 1,588.61 million standard cubic feet (MMSCF) of gas daily for full capacity.

But supply was only 652.92 MMSCF—roughly 40 per cent of requirements—leading to widespread generation shortfalls.

“NISO is actively working with Generation Companies (GenCos) and gas suppliers to monitor the situation and restore output as supply stabilises,” the operator said in a statement.It added that measures are in place to maintain grid stability amid the cuts, with ongoing updates promised to stakeholders.

NISO management signed off, reaffirming commitment to transparency on grid challenges.
