The Ghana Power Compact, funded by the Millennium Challenge Corporation appointed SMEC to help reduce technical losses across Greater Accra’s distribution network. Located in the southwestern part of Greater Accra the works incorporated a new 161/33kV Bulk Supply Point at Kasoa, to service sub stations in Cape Coast, Winneba and Mallam.
A key part of SMEC’s scope was to prepare the functional design and to review the EPC design of the gas insulated substation, only the second of its kind in the country. This innovative power solution incorporated a 50MVAr STATCOM regulator, which affords operators greater system control, because it can absorb and produce reactive power, which helps stabilise the network voltages.
SMEC then supervised the construction and commissioning of the substation and switchyard, providing project management and technical support. As part of the planned outages, SMEC scheduled an outage plan that minimised disruption to the local community. The energization process involved two major outages between sub stations.
Following a meticulous phase of pre-commissioning and final testing the outages were granted, enabling the team to carry out final connections. The energization process was successfully carried out the 21st of February 2022, marking a major milestone in the vision to increase power reliability and supply capacity in greater Accra.

The Tbilisi Development Fund has engaged SMEC to develop the Dighomi floodplain rehabilitation strategy. The Dighomi Floodplain is an area of special conservation interest, which includes riparian forest, protected Otter habitat and other unique flora and fauna ecosystems that have been assessed as critical by the International Finance Corporate Performance Standard.
SMEC has been contracted by Electricidade De Timor-Leste (EDTL) for the role of Project Supervision Consultants for the Power Distribution Modernisation Project in Timor-Leste. Supported by a loan from the Asian Development Bank (ADB), the project aims to assist EDTL in modernising the country’s power distribution system and strengthening institutional capacity.
Geotechnics will play a key role in helping our society achieve a safe, prosperous and sustainable future. Recent droughts have resulted in a need for more dam design and construction. Recent rainfall has resulted in extensive slop failures impacting our roads, rail and urban infrastructure. Energy transformation is driving large scale solar, wind and pumped hydro construction. These projects will all require geotechnical input to future plan for our communities.
