There was no power system collapse nor disturbance in the first quarter of 2025, a major improvement in grid stability, according to the latest report released by the Nigerian Electricity Regulatory Commission.
The report, which assessed grid performance, market remittance, metering, customer service, and safety, highlighted the regulatory commission’s push for enhanced system coordination by the System Operator, despite some operational challenges.
“There was no incidence of system disturbance on the national grid in 2025/Q1,” the report stated, attributing the milestone to improved grid management practices. However, while frequency and voltage readings stayed within stress tolerance bands, they still fell outside optimal operating thresholds, raising concerns.
The Commission noted: “In 2025/Q1, the average lower daily (49.28Hz) and upper daily (50.77Hz) system frequencies were outside the normal operating limits (49.75Hz – 50.25Hz) but within stress limits (48.75Hz – 51.25Hz). The average daily system voltage also fell outside the Grid Code-specified ranges,” it added.
The development follows years of persistent grid collapses, causing blackouts nationwide. In 2024, the grid collapsed 12 times.
