The importance Internet of Things (IoT) in managing the Nigeria 330kV power grid cannot be overemphasized. The nation’s power sector has been deviled with problems ranging from low voltages to total system collapse. There have been efforts to reverse the negative trends. One of the efforts was the development of robust modern technologies to monitor and control the systems in real time. Another challenge of note is the lack of visibility with the grid controller, which can be compared to driving a car with blurred windscreen. The existing SCADA system has lower coverage and parades about 22% visibilities to control operators. Internet of things (IoT) is machine to machine connection via the internet for the purpose of controlling, monitoring and exchanging information. A lot can be achieved via IoT like controlling remote actuators, sensing of remote device’s parameters such as temperature, position, voltage, current, and power. It helps controllers at the master stations or control centers to make informed decisions for better grid stability. The paper explains the design and implementation of the IOT based solution to the problems. It describes its components and deployment in twenty-nine power stations in Nigeria. The paper discloses that the application of the homegrown solution has brought visibility and stability to the Nigerian power grid network.
