The Shiroro Station, it was learnt, generates between 409megawatts and 380megawatts.
“Power generation will certainly drop by about 1,000megawatts in the event of the imminent drop in the water levels at the stations. The adverse effects of the low water level at this period of the year have been compounded by poor water management and inadequate maintenance of the stations, which has resulted to occasional leakage of water in the dams and flooding of the power stations,” a source close to the stations said.
According to him, Kainji, for instance, has not been overhauled since it was built in 1968.
But the Chairman of the Nigerian Electricity Regulatory Commission (NERC), Dr. Sam Amadi, however naijacelebritynews.blogspot.com gathered that the solution to the cyclical problems at the hydro stations was to increase gas supply to the gas-fired power stations to compensate for the expected fall in generation from the hydro stations.
“The answer to the cyclical hydro problem is to increase gas supply so that we can compensate the expected fall in hydro power generation to the national grid by enhanced supply from gas turbines,” he said. Amadi said if there was enough gas to support the thermal stations, the generation from the thermal plants would compensate for the expected drop from the hydro stations.
The Group Executive Director (GED) in charge of Gas and Power at the Nigerian National Petroleum Corporation (NNPC), Dr. David Ige,said yesterday that gas supply to the gas-powered generating plants had increased considerably since the repairs of the Escravos-Lagos Gas Pipelines.
He said though there had been routine operational hiccups, the development had not affected gas supply in recent weeks. “Since the pipelines came back, we have sustained gas supply to the power stations. Supply can trip today and come back tomorrow. For instance, it tripped in Seplat Petroleum Development Company at the weekend but came back midnight on Saturday. Pan Ocean also reported leakage on Sunday morning and we have sent people to check. If it is serious, we will shut down gas supply from Pan Ocean but it will affect only 30million standard cubic feet per day (mmscf/d) of gas,” he explained.
