The Electricity Distribution Companies (DISCOS) has allegedly rejected generated energy from power plants making it almost impossible for the country to enjoy a substantial, if not steady, power supply.
According to a report based on a summary review of the power sector from 13th to 20th August 2017, an average of 1,000 megawatts (MW) is being rejected daily by the Discos. Specifically, the 11 Discos collectively rejected 8, 391.06mw within eight days.
The analysis of the situation as reported by The Guardian shows that on August 20, a total of 818.01mw was rejected by all the discos; 626.97mw, 701.31mw, 1,581.39mw, 1,506.00mw, 1,202.01, 1,062.11mw and 890.26mw were rejected on the 19th, 18th, 17th, 16th, 15th, 14th and 13th of August.
Furthermore, the Daily Operational Report from the Transmission Company of Nigeria (TCN) has revealed that despite having a national peak demand of 19,100mw, the country was only able to generate 3,264mw on September 7, 2017.
The report explained that though the country has the capacity to generate 11,165.40mw, TCN has continued to transmit below its current capability of 7,000mw.
More report from the Nigerian Electricity Supply Industry Statistics (NESI) showed that the country lost an estimated N1.202 billion on September 5, 2017, due to several constraints inhibiting the power sector. NESI put the average power sent out on September 5, 2017 at 3759 mw, while the reported gas constraint was put at 450mw. It said that the power sector lost 2,055mw to reported frequency management constraint due to loss of Disco feeders.
While the electricity generation companies lament TCN’s inability to transmit available power to the distribution companies, which usually result in idle capacity, the Managing Director and Chief Executive, Dallas Peavey, said the company had been able to overcome the challenge of gas supply but had over 700mw of idle power which could not be transmitted to the distribution companies.
Mr. Sunday Oduntan, who is the director of Research and Advocacy, Association of Nigerian Electricity Distributors (ANED) said the insufficient power supply in the country will persist if TCN continued to face technical limitations which prevent the wheeling of power to some specific geographical locations.
“The issue is about the wrong dumping of load where the Discos cannot recover the cost as the power supply is not always enough for all the customers under a particular Disco.
“The truth of the matter is that TCN has not been able to properly transmit the generated power to the various distribution companies. If my customers are in Mushin, you cannot take the power to Victoria Island. How do you expect us to distribute such power?
“No matter how TCN wants to play it to colour the reality of transmission shortcomings, transmission remains the weakest link in the power value chain,” Oduntan said.
Speaking further on TCN’s capacity, the Executive Director, Niger Delta Power Holding Company (NDPHC), Sanusi Garba said,
“The liquidity problem in the sector must be resolved. All technical hitches at the transmission-distribution interface must be removed. It is vital to reinforce and expand the distribution infrastructure to take up more power from the system.”
Meanwhile, the General Manager (Public Affairs), Seun Olagunju, assured that TCN was working assiduously to improve and stabilise grid frequency at 49.75Hz to 50.25Hz.
According to her, the transmission company is working with the Nigerian Electricity Regulatory Commission (NERC) on the provision of required incentives for generation companies (Gencos) to provide enough spinning reserve.
