Industry reports showed that the instability in power production during the week was largely due to high frequency issues in the system occasioned by the loss of distribution company (Disco) feeders.
This, according to the sector’s National Control Centre, led to generation constraint in eight power plants, which are Shiroro, Kainji, Jebba, Odukpani, Geregu I, Omotosho I, Olorunsogo II, and Transcorp Ughelli.
The NCC also stated that line constraint to power generation was observed in two other plants and announced that the Transamadi station had been restored to the grid following outage since November 20, 2016.
In one of its reports during the week, it said, “High frequency due to loss of Disco feeders remains a significant constraint to generation in Shiroro, Kainji, Jebba, Odukpani, Geregu I, Omotosho I, Olorunsogo II, and Transcorp Ughelli. Also, there were increased line constraints at Olorunsogo I and Ibom.”
Further findings showed that the sector lost about N1.3bn daily during the week as a result of constraints to power generation, while an average of 1,400MW of power was not generated due to high frequency issues.
