This rural electrification project was implemented in two phases, covering network extension, substations, service connections and end use electrification for households and productive loads. Phase one included detailed design engineering and procurement for 271 kilometres of 22 kV lines, 76 village substations rated 22/0.4 kV, and 149 kilometres of 0.4 kV lines. The phase also included service connections and wiring of 5,200 houses, electrification support for 150 irrigation pumps, 115 small industries, and one concrete pole factory. The project work under phase one was physically completed in March 1987.

Phase two included detailed design engineering and procurement for three 115/22 kV substations with total capacity of 33.5 MVA, 11 kilometres of 115 kV line, 230 kilometres of 22 kV lines, and 90 village substations rated 22/0.4 kV. The phase also included 285 kilometres of 0.4 kV lines, service connections and wiring for 6,000 houses, electrification for 130 irrigation pumps and 115 small industries. Phase two commenced in 1984 and was completed in 1989.

TCE's Scope

For phase one, TCE carried out detailed design engineering and procurement and provided guidance and supervision of construction and commissioning for parts of the works. For phase two, TCE provided detailed design engineering and procurement, along with construction supervision and commissioning for the 115 kV line and all three 115/22 kV substations. The scope also included review of accounting and financial procedures and on the job training for accounts and finance staff.

Impact

The project enabled large scale rural electrification through multi voltage network build out, village substations and household connections, expanding access across households and productive loads such as irrigation and small industries. The addition of 33.5 MVA of 115/22 kV substation capacity in phase two strengthened supply capability and improved system robustness for continued growth.
