The Nigerian Independent System Operator (NISO) has attributed the current decline in electricity generation across the national grid to constraints in gas supply to thermal power plants and reduced output from hydroelectric power stations.
The operator disclosed this in a statement issued by its management on Thursday, explaining that limited gas availability has prevented some thermal power stations from operating at their available capacities.
It also identified reduced water inflows into reservoirs as another major factor affecting the generating capacity of hydroelectric power stations.
According to NISO, the combined challenges have reduced the volume of electricity available on the national grid, consequently affecting the quantity of power allocated to Distribution Companies (DisCos) for onward supply to consumers.
The development has resulted in shorter hours of electricity supply and increased load shedding across distribution networks, with the level of disruption varying among DisCos depending on available generation and their respective allocations.
NISO acknowledged the difficulties faced by electricity consumers nationwide, expressing appreciation for the concerns raised by members of the public and other stakeholders over the persistent decline in power supply.
The operator further assured Nigerians of its commitment to maintaining grid stability, optimising the distribution of available electricity and ensuring the secure, reliable and efficient operation of the national grid despite the prevailing constraints.
It added that efforts were ongoing to diversify the national energy mix to strengthen electricity supply security and improve the reliability of the power system.
