Over N534 billion in revenue was lost by the power sector in 2016, according to the Nigerian Electricity Supply Industry (NESI).

Among the reasons for the loss are shortages in gas supply, frequency and line limitations and water levels management constraints that led to several cases of outage in the country.

NESI, which put the average daily revenue loss at N1.5 billion, said gas constraint remained one of the major challenges facing the electricity sector.
The N534 billion is the value of electricity lost on account of the challenges, part of which could have been used to bridge the liquidity gap in the power sector, that is put at N1trillion. Already, the sector is finding it difficult to access more loans from Nigerian banks due to their inability to meet the payment obligations for previous debts. The situation will also affect the capacity of the power firms to improve on electricity supply to consumers for domestic and industrial uses.

NESI said in its daily statistics on energy losses that the industry lost N1.525 billion on December 24, 2016 alone. It was also disclosed that about 12 power stations could not produce electricity during off-peak under the review period.

Statistics from the National Control Centre, Osogbo, showed that Afam IV-V, Geregu Gas, Alaoji National Integrated Power Project (NIPP), Olorunsogo Gas, Odukpani NIPP, Okpai, Ibom Power, ASCO, AES, Amoku, Rivers NIPP and Gbarain power plants could not produce a single megawatt (MW) on December 25, 2016. Nigeria has installed power output of 11,165MW, of which the 12 plants have combined capacity of 2,035MW.

If this continues, industries and other users will carry on with the burden of providing own electricity outside the national grid even in the new year. Production and prices of goods and services will be negatively impacted and hopes of any early recovery from the current recession will be dimmed.

The electricity generation report obtained by The Guardian showed that Isolated Ground (IG)10 belonging to Kainji Hydro was shut down on Christmas Day due to temperature problem while IG12 was out of operation due to high water leakage.

Also, Steam Turbine (ST) three and four belonging to Egbin were out of operation due to gas constraints. Although with a capacity to generate over 880mw, the unit was only able to produce 278MW.

It was also learnt that contribution from the hydro-power stations dropped in September to 32.95 per cent from their combined contribution of 36.64 per cent in August.

The third Quarter National Grid Performance Information from the Independent System Operation, Transmission Company of Nigeria (TCN) showed that the Shiroro Hydro Power Station maintained its lead with 14.75 per cent, though down from 15.90 per cent in August.

Egbin Power Station produced 14.05 per cent of the total electricity in the system, which led to a slight increase in the contribution of privatised thermal power stations in September to 29.22 per cent from 28.25 per cent in August.

Aside the drop in power generated, many distribution companies (DISCOs) rejected electricity supplied to them by the generation firms (GENCOs).

For instance, in September 476.36MWH or 12 per cent of the total energy delivered to the DISCOs was rejected, constituting the highest load rejection in the quarter. The breakdown shows that Abuja Disco rejected 94.72 MWH, Port Harcourt Disco with 92.35 MWH, Ibadan 67.14MWH and Benin Disco 46.40 MWH.

Among all the distribution companies, only Kaduna accepted power beyond the MYTO allocation. It was 65.96 MWH in excess.

The DISCOs had in August rejected about 541.56MWH, which was four per cent of the total energy delivered to them. Port Harcourt Disco rejected the most megawatts totaling 239.88. It was followed by Eko Disco with 134.8 MWH.

On the other hand, in august, five Discos took excess loads beyond their MYTO allocation of 187.21MWH. Abuja Disco took the most with 132.81 MWH, followed by Kaduna Disco with 23.21 MWH, Ibadan Disco with 16.24 MWH and Enugu with 12.42 MWH. All these made peak electricity generation to remain stagnant at 3,890.1MW.

But, in defence of the Discos rejecting the allocated electricity, the Executive Director, Research and Advocacy, Association of Nigerian Electricity Distributors (ANED), Sunday Oduntan, said the development was unavoidable.
