THE national power grid dropped considerably between Saturday and Sunday as twelve power plants in the country could not generate 1,609.9 megawatts of their total installed capacity, a number of newspapers reported on Monday.
Although power supply has considerably been poor in Abuja and environs for over a week, it was only on Sunday that data obtained from the Nigerian Electricity System Operator (NESO) officially confirmed the drop was due to gas constraints.
The total unutilised electricity generation capacity in the country stood at 2,242.1MW as of 6am on Sunday, with low load demand by the distribution companies, water management and line constraints stalling the generation of 632.2MW, reported the Punch newspaper.
The report further noted that the power plants affected by gas shortage included Omotosho I, Olorunsogo I, Omoku, Afam VI, Omotosho NIPP, Trans-Amadi and Sapele NIPP. Others were Geregu NIPP, Olorunsogo NIPP, Egbin, Rivers IPP, and Geregu I, according to data obtained from the Nigerian Electricity System Operator.
The NESO data also showed that the plants on the national grid produced 4,358.9MW as of 6am on Sunday, down from 4,660.1MW on Saturday. Egbin, the nation’s biggest power plant, saw its output decline to 712MW as of 6am on Sunday from 832MW on Saturday.
Ten plants, including six plants built under the National Integrated Power Project, did not produce any megawatts of electricity as of 6am on Sunday. The idle plants were Sapele NIPP, Alaoji NIPP, Olorunsogo NIPP, Omotosho NIPP, Ihovbor, Gbarain, Ibom Power, AES, ASCO and Egbin ST6.
The country generates the bulk of its electricity from gas-fired power plants, while output from hydropower plants makes up about 30 per cent of total generation. The hydropower plants are Kainji, Jebba, Shiroro and Dadin Kowa.
