The Transmission Company of Nigeria, TCN, has explained that shortage of gas supply is responsible for the electricity blackout in many parts of the country.
According to Premium Times, the TCN, on Sunday, said the situation has led to significant reduction in power generation and distribution.
The electricity agency said the gas shortages affected over half a dozen power generating facilities across the country, but has, however, not resulted in a total blackout.
Ndidi Mbah, a spokesperson for TCN, said a gas pipeline rupture was reported by the Nigeria Gas Company, NGC on June 15.
The spokesperson also disclosed that Shell Nigeria gas wells also developed a fault on June 16, causing a drop of 1,087 megawatts in national grid generation.
The situation has compelled distribution companies to embark on a “massive load-shedding nationwide’ in order to “maintain stability of the grid,” Mbah said.
Power stations that have reportedly been shut down to various faults include, the Ihovbor, Azura Edo, Omotosho gas, Geregu gas, Olorunsogo gas, Sapele and the Egbin Power Station. Egbin generates 60 megawatts on each of its units, losing a total of 211 megawatts.
According to the TCN spokesperson, Afam VI power Station has been shut down, to enable Shell resolve the damage to its gas wells and be back online. She disclosed that the issue had been partially resolved, and Shell was able to supply power to Afam VI, although at a low capacity for now.
Mbah further said efforts have intensified to avert a collapse of the system. There were reports that there was a total nationwide blackout on Saturday.
But the spokesperson refuted such claims, saying; "there was no collapse of the grid as reported in the news.”
The disruption comes six months after the country experienced a total blackout due to a fire outbreak at a facility; which was acknowledged by Tunde Fashola, the Minister of Power, Works and Housing.
