The electricity national grid has collapsed again leaving the country without a public power supply.
The latest collapse, the third in less than a month, came despite assurances by the Federal Government that it has taken steps to address the problem.
The Transmission Company of Nigeria (TCN) which manages the grid last month said it had developed alternative ways of managing the grid.
TCN had stated that its “in-house engineers have deployed a stop-gap solution to improve grid monitoring and acquisition of data from remote stations (power stations and transmission substations) to the National Control Centre.
“This was achieved by utilizing the Internet of Things (IoT) solution, and Virtual Private Network (VPN) by using various Internet Service Providers (ISP).
“This temporary use of the Network Automation System was deployed to assist TCN in conveying critical operational measurements data from remote stations to NCC using Web Technology, which is an integral component of the IoT.
“So far, the data received from remote stations has enabled NCC to obtain more insight into the situation of the power flow on the grid and has enabled NCC to make decisions that have impacted positively on the security and integrity of the Grid.
“The stop-gap solution became necessary as TCN could not access and receive comprehensive operational data of the entire power grid for managing the fast-growing system. The existing inadequate SCADA System cannot provide adequate grid visibility, as parts of the existing SCADA system are moribund and damaged, coupled with an ineffective telecommunication network infrastructure. The fact that several stations were never integrated into the existing SCADA at all, and made grid visibility and management very difficult and inefficient”.
