The national electricity grid witnessed another collapse on Tuesday that resulted in the drop in power generation from over 3,000 megawatts to just 108.7MW
Industry data showed that power generation plunged from 3,069.5MW on April 8, 2017 to 108.7MW on April 9, and moved up marginally to 240MW the next day. It was learnt that heavy rainfall at three transmission stations led to load reduction that prompted high frequency in the system, a development that triggered the collapse of the electricity grid, the first to be recorded in the second quarter of this year.
Tuesday’s report on the April 9 system collapse stated that the rainfall affected the Onitsha, Benin and Alaoji transmission stations, leading to a cumulative load reduction of 384MW in the affected areas. “This led to a rise in system frequency and voltage, which subsequently resulted in the transmission line tripping as indicated in reports from the stations. The development, according to officials of the Power ministry, worsened electricity supply in many areas during the period.
