The Ghana Free Zones Board (GFZB) was to attract Foreign Direct Investment (FDI) at its new acquired
enclave at Dawa in the Greater Accra region of Ghana. It decided to build a power network within the
enclave to make electrical power available and independent from the national grid to be managed by an
Independent Power Producer (IPP). The design submitted by an Engineering Procurement Contract (EPC)
is shown in Fig.2.
