Gas Shortfall Slashes National Grid Electricity Supply to 4,300MW—NISO

Nigeria’s grid power has plunged to 4,300MW due to a 937.75MMSCF daily gas shortfall to thermal plants, the Nigerian Independent System Operator (NISO) has said.

The System Operator, explained in a public notice, that thermal plants, which dominate the generation mix, require an estimated 1,629.75 million standard cubic feet (MMSCF) of gas per day for optimal operation, but actual supply as of February 23 stood at just 692 MMSCF—less than 43 per cent of needs, creating a 937.75 MMSCF daily shortfall.

The operator stated that this constraint has reduced energy allocation to Distribution Companies (DisCos), necessitating load shedding to maintain grid stability in line with NERC MYTO percentages.

NISO regretted the inconvenience to consumers and market participants, adding that it would continue working with stakeholders to restore full allocation once gas supply improves.

“The current average available generation… is primarily due to inadequate gas supply,” NISO stated.

This forces load shedding and cuts energy to DisCos to keep the grid stable, per NERC MYTO rules. NISO regrets the “inconvenience” to consumers and pledges to work with stakeholders for restoration.

The crisis highlights ongoing gas woes like vandalism and debts, stalling Nigeria’s power reforms amid rising demand.
