Strategy 8 power plants shut down as Nigeria loses N108 billion in first quarter over operational constraints

Some of the power plants tripped due to low gas pressure while GT3 was shutdown due to generator air inlet filter trouble.

8 power plants shut down as Nigeria loses N108b over constraints play

Eight of Nigeria's 27 power plants have shut down days after data showed that the country's power sector lost N108billion to operational constraints.

  • Eight out of the 27 power plants in Nigeria were shut down on April 9, 2018 as a result of operational constraints that include gas, line and frequency management.

  • Some of the power plants tripped due to low gas pressure while GT3 was shutdown due to generator air inlet filter trouble.


Eight out of the 27 power plants in Nigeria were shut down on April 9, 2018 as a result of operational constraints that include gas, line and frequency management.

A data from the Power Generation Report by the Ministry of Power, Works and Housing, shows that these constraints affecting the power plants might be responsible for the low power generation.

Affected power plants

Trans Amadi Gas Turbine (GT)

The power plants 1 and 2 were out due to line constraints while GT 3 was on fault. GT 4 tripped on generator differential lockout.

ASCO Power plant GT1

This power plant was shut down due to leakage in the furnace

Ihovbor Nigerian National Integrated Power Project (NIPP) GT 1

This power plant was out due to gas constraint. GT2 was also out due to malfunctioning gas regulating valve.

Alaoji NIPP Gas Turbine

The power plant 1, 2, and 4 tripped due to low gas pressure while GT3 was shutdown due to generator air inlet filter trouble.

Afam IV and V Gas Power Plant

GT13-16 were out on blade failure while GT17 tripped on loss of excitation. GT18 was out on inspection and maintenance, while GT19 and 20 are awaiting major overhaul.

Sapele Steam

ST1 tripped on low drum level, ST2 was shut down for maintenance, ST3 was out on stator winding problem, ST4 and 5 are awaiting major overhaul while ST6 tripped on gas control valve not following reference point.

January's Loss was valued at over N1.5billion

In January alone, the average power generated and distributed was 3,971mw while 2,302.8mw was not generated due to unavailability of gas.

In the same vein, as a result of the unavailability of transmission infrastructure, about 417mw was not generated high frequency resulting from unavailability of distribution infrastructure disturbed the generation of while 290mw.

As a result of all these constraints, the power sector lost an estimated N1.584 billion on January 25, 2018, due to insufficient gas supply, distribution infrastructure, and transmission challenges.

The constraints

The Nigerian power sector has been plagued with structural issues in all key areas that include generation, gas supply, transmission, and distribution.

Sadly, the operational capacity of the country’s power plants is less than a third of their installed capacity.

As it has been mostly reported, chronic vandalism has crippled oil and gas pipelines, creating gas shortages at power plants.

In the same vein, underinvestment in maintenance and infrastructure has constrained the transmission grid.

Need to utilise renewable energy

Nigeria's Minister of Power, Works and Housing, Babatunde Raji Fashola, has emphasized the need to utilise renewable energy in the country.

The Minister said efforts must be concentrated to develop renewable energy along with conventional power plants to maintain a balanced energy in the short, medium and long term.

Fashola said renewable energies were the fastest power plant that can be deployed as the technologies required are compatible with what he described as the nation’s decentralised, stand alone for local and rural communities.

He stated: “The huge energy deficit and the negative environmental impact of using fossil fuel for energy generation as well as the falling costs of renewable energy technologies like solar power, are driving the current energy transition towards renewable energy as being witnessed across the world.

The Minister also said the Federal Government is implementing off-grid renewable energy solutions such as rural mini-grids, and standalone home solutions.
