Ghana’s Volta River Power Authority has awarded ABB an order worth over $13 million to improve the management and control of the country’s national power transmission network.

Working with the Ghana Grid Company, ABB will supply, deliver, install and commission a new supervisory control and data acquisition/energy management system (SCADA/EMS) and communications system that will enable the efficient management and control of the power network as well as reduce transmission losses.

The project is a key component of the 330 kV Coastal Transmission Backbone initiative, a programme 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, fibre optic terminal equipment and the power line carrier communication system to connect the control centre 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.
