A reduction in the available gas supply has led to two thermal power stations in Nigeria shedding load and electricity supply falling to 500MW.

The Power Holding Company of Nigeria Plc (PHCN) were forced to reduce generation from its two power stations by about 500 mega watts, a statement from the PHCN has said.

"In view of this [reduction of gas supply], we have no alternative than to start load shedding again. The load shedding is due to factors entirely outside our control and we deeply regret the inconvenience to our customers".

The two power stations affected are Egbin and Delta Power Stations. Egbin, which is located in Lagos, is currently the major supplier of electricity, which a capaicty to produce approximately 1 100MW.

However, gas shortages in recent months have resulted in generation shortages on many occassions.

In the statement, PHCN said "this latest disruption in gas supply is coming just when all our efforts at improving power supply has started yielding results".

"For the past two weeks, power supply stabilized with minimal load shedding eliciting commendation from Nigerians. Just as we were settling down at this comfort level, the Nigerian Gas Company has again directed us to reduce generation output from the two thermal power stations by about 500mw".
