Transmission system stability not guaranteed below 3,000MW – TCN


The Transmission Company of Nigeria (TCN) has stated that the stability of the transmission network cannot be guaranteed whenever power generation drops below 3,000 megawatts, ThisDay reports.

Speaking in Lagos at the weekend, the Managing Director of TCN, Mr. Abubakar Tambuwal Atiku, blamed frequent system collapses on inadequate gas supply to the generating plants. The transmission network has recorded over 20 system collapses in 2016, which were largely blamed on the weak transmission network, which is regarded as the weakest link in the electricity value chain.

But Atiku argued that the system is susceptible to collapse whenever generation is below 3,000MW, adding that the current 20-30MW spinning reserves is not enough to save the system from collapse whenever up to 300MW is suddenly lost by the grid. He insisted that the transmission network has a capacity to wheel 7,000MW, stressing that gas shortages have made it difficult for generation to improve.
