ABB has won an order worth over $13 million from the Volta River Authority in Ghana to supply equipment to improve the management and control of the country’s national power transmission network.
Working with Ghana’s electrical transmission provider, Ghana Grid Company, ABB will supply, install and commission a new scada energy management and communication system, which includes advanced functions for network analysis and optimisation, automatic generation control, energy interchange scheduling and transaction monitoring.
The project is a key component of the 330 kilovolt 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. Comprehensive training will be given to employees. The project is expected to be completed in 19 months.
