Nigeria records 4% drop in energy generation in Q2

NERC warns of grid instability

Nigeria Electricity Regulatory Commission, NERC, said a four per cent drop in electricity generation in the second quarter of the year might result to grid instability.

The amount of energy generated by the 25 power generating plants in Nigeria recorded a decline of 3.55 percentage points from 69.59 per cent recorded during the preceding quarter.

The average dispatch rate stood at 66.04 per cent during the second quarter, indicating that an average power plant operating during the second quarter 2019 had just 66.04 per cent of its available capacity dispatched by the System Operators, SO.

Two of the 25 power plants in operation during the quarter under review had at least 80% of their available capacity dispatched by SO. The plants are Omotosho NIPP and Paras Energy. Shiroro hydropower plant, which has one of the lowest tariffs, recorded the least dispatch rate at 41.24 per cent.

To ensure that hydro plants are efficiently dispatched given their low tariffs and in consideration of safety associated with spilling of water from dams during the rainy season, NERC said it has issued an order declaring hydro plants as “must-run” by SO. Similar to the preceding quarter, Paras Energy had the highest dispatch rate (load factor) of 87.15 per cent followed by Omotosho NIPP, which recorded 86% load factor. During the same period, Azura power plant had 65.95 per cent load factor.

Eleven of the 25 operational power plants accounted for 72.87 per cent of the total electric energy generated during the second quarter. Egbin power plant accounted for 12.06 per cent of the total energy output followed by Transcorp power plant (Delta), which accounted for 8.5 per cent energy share.

Gbarain power plant accounted for the least share of output during the quarter with 0.53 per cent- these shows clearly that energy generation in Nigeria still heavily depends on a few numbers of plant, as 7 of the operating plants accounted for 53.93per cent of the total electric energy output in the second quarter of the year.

NERC said the implication is that the seemingly over-reliance of the grid on the energy supplied from just seven power plants may pose a risk to the industry because downtime in any of them may result in grid instability if there are no adequate proactive measures such as adequate spinning reserves.

In order to mitigate the risk to grid stability that may arise from inadequate generation from any of the seven major plants, the Commission said it has commenced the evaluation of the outcome of the competitive procurement of spinning reserves conducted by the Transmission Commission of Nigeria, TCN- the procurement of adequate spinning reserves, NERC said is to ensure proper management of the grid by the SO.
