The Nigerian Independent System Operator has attributed recent reductions in electricity allocations to Distribution Companies serving Lagos, Abuja and northern parts of the country to multiple transmission line outages that constrained the capacity of the national grid.
The system operator said the outages forced it to adjust generation dispatch and power allocations to ensure that the remaining transmission network operated within safe limits and to prevent a wider system disturbance.
In a statement signed by its management on Sunday and titled, “Clarification on Recent Changes in Power Allocations Following Transmission Line Outages,” NISO said the changes were caused by transmission constraints and not a shortage of generation.
The clarification came amid concerns over changes in power allocations to DisCos in some parts of the country.
NISO said, “The Nigerian Independent System Operator wishes to provide clarifications on the recent changes in power allocations to Distribution Companies serving the Lagos, Abuja and Northern corridors. The changes in allocations occurred due to multiple transmission line outages that affected available transmission capacity and configuration of the network at different times. Adjustments were made in the course of normal system operations to ensure that the interconnected network remained within secure operating limits.
