Working with Ghana’s electrical transmission provider Ghana Grid, ABB will supply, deliver, install and commission a new supervisory control and data acquisition/energy management system (SCADA/EMS) and communications system, which includes functions for network analysis and optimization, automatic generation control, energy interchange scheduling and transaction monitoring.
According to ABB, the project is a key component of the 330kV Coastal Transmission Backbone initiative, a program financed by the World Bank to improve the reliability of power supplies by encouraging efficient power trading between the coastal countries of West Africa.
The communications equipment includes remote terminal units for around 50 substations, fiber optic terminal equipment and the power line carrier communication system to connect the control center and the substations. Ancillary equipment such as uninterrupted power supply units, video surveillance systems and other telecom components will also be supplied. The project is expected to be completed in 19 months.
