…why DisCos reject load from GenCos

22 July 2017, Sweetcrude, Lagos — Over time, you must have heard the electricity distribution companies talk about ‘load rejection’.
Just in case you have been wondering what the term implies, here is a glimpse of what you should know about it.
Normally as a business organisation, the discos will nominate supply to places where customers are paying and where their equipment is working.
However, in places where the collection is difficult or equipment are not functioning, they will refuse to energise their power intake because customers are not paying, or are unable to do so because their equipment is bad. This is what is called load rejection.
What then happens is that the Control Centre tells the GenCos to reduce their power production because if it (power) is not taken, it results in high frequency which can damage the generating unit, create a loss of power, and sometimes result in grid collapse depending on how severe the outage is.
The problems came on the horizon as gas is improving and rains are arriving in increasing power production on thermal and hydro plants.
