Why we informed GENCOs to reduce generation —TCN
system frequency, demanded corrective measures, joined with the rejection to
take more loads by Distribution Companies, DISCOs, forced it to notify GENCOs
to lessen generation.
who is the Managing Director of Mainstream Energy Solutions, Workers of Jebba
and Kainji Hydro Electricity Plants, that GENCOs could no longer stand the continuous
reduction of energy production on the orders of the TCN.
2017, Jebba and Kainji alone lost about 8,574 MW unutilized electricity.
GENCOs within the period under evaluation was huge and most painful at a time
most Nigerian homes and businesses barely had adequate power supply to meet
their consumption needs.
General Manager, Public Affairs, Mr Seun Olagunju, said in overall, electricity
was not stored but utilized as it was being produced.
“Recently, high system frequency (more than 50HZ) has been observed,
necessitating corrective measures. The options to bring down the frequency to
50Hz are:(a) Distribution Companies to absorb more load, (b) Generation
Companies to reduce generation.
the appropriate line of action. However, due to inexplicable reasons, some
DISCOs failed to take more load as generation increases. This has left the
system operator with no other option than to ask the GENCOs to reduce
generation to ensure grid stability.
GENCOs to reduce generation is imperative to maintain the integrity of the
grid, as frequency higher than 50HZ could result in system disturbance.
note that the directives are issued with a high sense of duty and
responsibility to the nation and the entire electricity industry.
decision is based on the fact that at normal operating frequency of 50Hz, the
active power generated is equal to the active load consumed and losses.
generated power is more than the load connected, the frequency rises higher
than 50Hz, which can result in system disturbance.
imbalance, the system operator, whose duty it is to maintain system stability,
has no choice than to ask the generating stations to drop the load to sustain
the network integrity.
all over the world. On the contrary, if the load connected is higher than the
generated power, the frequency drops below 50Hz and can also lead to system
collapse.”
