The Sunyani Substation project was designed together with the Mim Project to improve on the supply reliability to Northern Electricity Distribution Company (NEDCo) and also to provide an alternative supply source to the Electricity Company of Ghana (ECG) to serve their load in the northern section of the Western Region which was being served from the Bogoso substation.
The objective was to upgrade the existing Sunyani – Mim transmission line which was insulated at 161kV but was at the time energized at 34.5kV and to construct a 161/34.5kV substation at Sunyani.
Design and construction of a 161/34.5kV substation, which will be configured as a single bus arrangement to be converted, in the future, into a ring bus This will involve the design, supply and installation of balance of plant including but not limited to 161kV circuit breakers, 161kV disconnect switches, 161kV current and voltage transformers, 161kV surge arrestors, 34.5kV feeder equipment complete, protection and control system, AC/DC station auxiliary, metering equipment, buswork, associated civil work, etc.
Supply and installation of 1Nos. 161/34.5kV, 25/33MVA Power Transformers.
Supply and installation of 1Nos. Grounding/Auxiliary transformers 1Nos. Auxiliary transformers.
Supply and installation of line terminal equipment for the new Sunyani outgoing line to Mim.
Provision of communication and SCADA system at Sunyani substation.
All civil works associated with the above works including but not limited to
survey, substation site clearing, leveling, filling and compaction, control building, drainage, fencing with gates, equipment plinths, tower foundations, etc.
Sunyani-Mim transmission line right of way bush clearing, provision of culverts and access roads rehabilitation.
