The Transmission Company of Nigeria (TCN) has explained the reason why many parts of the country are experiencing blackouts.
The agency, which has the sole responsibility of transmitting generated power, said in a statement on Sunday that there were shortages in gas supply which led to a significant reduction in power generation and distribution.
It, however, said there was no total blackout.
The shortages affected over half a dozen power generating facilities across the country.
Ndidi Mbah, a spokesperson for TCN, said a gas pipeline rupture was reported by the Nigeria Gas Company (NGC) on June 15.
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,” Ms Mbah said.
Power stations that have 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, the official said. The facilities are scattered across the country.
Also, Afam VI power station was shut down to enable Shell resolve the damage to its gas wells and be back online. The issue had been partially resolved and Shell was able to supply power to Afam VI, although at a low capacity for now.
Mbah said efforts have intensified to avert a collapse of the system.
Load-shedding is a critical way of ensuring that available generation is equitably allocated to distribution companies nationwide, to create a balance and avert grid instability.
Mbah said there was “no collapse of the grid as reported in the news.”
