Power Generation Drops By 800mw

By Chika Amanze-Nwachuku, 03.11.2008

The current power outages being experienced in parts of the country may get worse due to  inadequate gas supply to fire the turbine power stations. Consequently, power generation capacity has dropped by over 800MW.

A statement last night by the Power Holding Company of Nigeria (PHCN) confirmed a steady decline in gas supply from the Nigeria Gas Company (NGC) to Egbin and Geregu power stations due to the buildup of condensate in the Escravos gas pipeline.

The power company said sequel to the non availability of adequate gas to power the plants, power generation at the Egbin Power station has reduced from 800MW to only 100MW and a daily shortfall of 150MW at the Geregu Power Station. Egbin has the capacity to generate 1,320MW of electricity, while Geregu’s generation capacity is 414MW.

The PHCN also hinted that power supply may still worsen this week as the commencement of pigging of the Escravos gas pipeline by NGC to evacuate the condensate may further reduce gas supply to the power stations.

The statement read: “The Management of Power Holding Company of Nigeria (PHCN) regrets to inform its esteemed customers that for some months now gas supply from Nigeria Gas Company (NGC) to Egbin and Geregu power stations has steadily declined due to the buildup of condensate in the Escravos gas pipeline. As a result daily power generation at Egbin power station has reduced from 800MW to 100MW, a total reduction of 700MW and also a daily shortfall of 150MW at Geregu gas plant.

The inadequate gas supply to fire the available turbines has led to a loss of over 800MW.  This great loss has impacted negatively on power supply giving rise to load shedding nationwide. The Nigerian Gas Company this week commenced pigging of the Escravos gas pipeline to evacuate the condensate, which may further reduce gas supply to the power stations.  The inadequate gas supply to these stations is further compounded, coming in the middle of the dry season when the dams that supply water to the hydro power stations are at their lowest level thereby limiting their generation capacity and ability to augment the thermal units. We wish to inform the public that the prevailing load shedding is due to factors entirely outside PHCN control”.

The NGC had last November shut down gas supply to Egbin, Delta and Geregu Thermal Power Stations, a development which led to a complete shut down of Egbin. Also in  October last year, the Utorogu Gas Plant belonging to the Shell Petroleum Development Company (SPDC) was shut down following the fire that gutted the 10-inch Utorogu-Ughelli Pumping Station  condensate trunkline. The incident resulted in the deferment of some 300 million standard cubic feet of gas, a development which affected power supply as the turbines are fired by gas.  The PHCN has often attributed  the frequent outages to inadequate gas supply to the power stations by the gas company. The shut fall in gas supply to the power stations which started last October often leads to generation limitations thereby giving rise to the on-going load shedding.
