Work will soon commence on the Supervisory Control and Data Acquisition (Ss) Upgrade Project with contractors Hitachi Energy.
This aspect of the SCADA works seeks to upgrade to the latest version, the Network Manager System (NMS) application and servers currently in use. Upscaling to the latest version will increase the resilience and protection of the system from potentially harmful viruses, spyware and other malicious software.
The upgrade also aims to increase the licensed capacities NMS in terms, such as the number of communication lines; number of thin-client users; number of data points (measurands, alarms, indications etc.), applications and other functionalities of the existing SCADA NMS.
Also included in the upgrade is the replacement of the video wall at the System Control Centre and the establishment of a Back Up Control Centre to ensure security of electricity supply across the National Interconnected Transmission System (NITS) in the event of an emergency that makes it impossible to control the power system from the main Control Centre.
The kick-off meeting, held on Friday 3rd February 2023 was led by Ing. Frank Otchere, Director of System Operations and Ing. Nicholina Yembilah, Director of Procurement with other team members in attendance.
