Power Grid Records 21 Collapses In Six Months

A data from the Transmission Company of Nigeria (TCN) has disclosed that the nation’s power grid, in the first half of the year, recorded 21 collapses.

Out of these, 16 were complete collapses, while five were partial collapses recorded in the period.

In the whole of 2015 and 2014, the grid collapses were 10 and 13 respectively, with four partial collapses each.

According to the data from TCN, the latest total system collapse was recorded on June 28, 2016, while the electricity supply to households and businesses across the country dropped significantly in May as the national grid recorded six total collapses and one partial collapse.

In June, the grid recorded five total collapses and three partial collapses, with the latest occurring on June 11.

The total national power generation stood at 2,604.5 megawatts, as at last Friday, down from a peak of 5,074.7 megawatts on February 2, according to the Ministry of Power.

Generation from Egbin, the nation’s biggest power station, stood at 187 megawatts on July 6, down from 1,085 megawatts on March 15.

Shortage of gas due to recent attacks on pipelines in the Niger Delta contributed to low power supply, as it left over 4,000 megawatts of the nation’s power generation capacity idle.

The Ministry of Power’s data disclosed other factors limiting electricity generation were line constraints and load rejection by the distribution companies and water management/maintenance.

Gas constraints prevented 3,810 megawatts from being generated on July 6, while 355.7 megawatts could not be generated due to line constraints/load rejection by Discos.

Information gathered revealed that the country generated most of its electricity from gas-fired power plants, while output from hydro-power plants make up about 30 per cent of total generation.

The data from TCN further revealed  that as of June 3, the unutilised generation capacity was 4,016.6 megawatts with 3,661.1 megawatts due to gas constraints; 355.6 megawatts caused by line constraints/rejection by Discos and 380 megawatts as a result of water management/maintenance.

The Minister of Power, Works and Housing, Mr. Babatunde Fashola, recently said, “In our road map to incremental power, we are looking at what we have and what we can get out of them.

“We have 26 power plants (including the AES plant), three of the plants are powered by water, the hydro power plants in Jebba, Kainji and Shiroro. The rest are powered by gas.”

He put the total number of turbines, which should actually generate power from 25 power plants (excluding AES), at140 turbines with installed capacity of 12,341 megawatts.

Fashola added: “At the best of times, only about 78 turbines are generating power which gave us our peak of 5,074 megawatts. The problems have been identified as either damaged, unmaintained or unserviced turbines in the hydro power plants, and in the cases of gas plants, it is largely non-availability of gas, coupled with lack of maintenance.”
