Spinning Reserve Dips to 9.8 Megawatts

Some stakeholders of the Electricity Distribution Companies  (DisCos)  yesterday raised the alarm over the dip in the spinning reserve in the electricity market to 9.8 mega watts (Mw).

Spinning Reserve is the difference between the total generated energy and what electricity system operator sends out to the DisCos.

But the “reserve which is supposed to be a sort of storage that the market should have a recourse to when the grid breaks down or there is any emergency is fast depleting to nothing,” an industry stakeholder said yesterday.

He added that the spinning reserve serves to keep the grid stable.

The reduction, according to a source from one of the power generation companies (GenCos), was due to attacks on the nation’s gas pipelines.

Prior to the attacks on the pipelines, spinning reserves was about 72Mw but it was 9Mw on May 27, rose to 32Mw on May 28, and dipped to 9Mw on May 29 and yesterday it reduced to 9.8Mw.The Nigeria Electricity System Operator noted on its website that on Sunday, the energy that was sent out to the DisCos was 1,978Mw and that its lowest generation was 175.60Mw, adding that the market hit a peak generation of 2,910Mw.

The Nigerian Electricity Supply Industry (NESI) said on its website that “on May 29, average energy sent out was 1978Mwh/hour (down by 482Mwh/h). The reported gas constraint was 3,481Mw. The reported line constraint was 97Mw. The water management constraint was 380Mw. The power sector lost the estimated equivalent of N1, 900, 000, 000 on May 29 due to constraints.”
