It also includes the construction of 11 new substations (four in Liberia, five in Sierra Leone and two in Guinea) and expansion of an existing substation in Cote d’Ivoire. In addition, the project will include the development of an optical ground wire network and installation of a supervisory control and data acquisition system at the Regional Control CentreinLinsan (Guinea), which will facilitate interconnection operations. The project is part of the five priority projects of the larger West African Power Pool programme, which will establish a well-functioning and cooperative power pooling mechanism for West Africa. It will provide electricity connections to the four countries, utilise the Bumbuna hydropower plant in Sierra Leone and redevelop the Mount Coffee HPP in Liberia.
