Mauritania - Construction of a 120 (180) MW dual-fuel power plant in Nouakchott
The state-owned utility SOMELEC is currently constructing a new power plant in Nouakchott to answer the steadily increasing power demand in the city and eventually in the national and international grid. This power plant, in its initial phase, had a capacity of 120 MW (8 x 15 MW dual-fuel gen sets, operated either with HFO or gas). In the second phase, the plant is currently extended to 180 MW capacity by adding a further four gen sets.

Nigeria - "Transmission Lines and Associated Substation Agreement" for the 80 MW AC Nova Scotia Solar PV Project
Nova Scotia Power Development Limited (NSPDL) is developing a ground-mounted 80 MW (AC) solar PV plant. The proposed site is located some 5 km from the town of Dutse in Jigawa State. The proposed plant will be connected to the national transmission grid by means of a 132 kV double-circuit overhead line between the step-up transformer at the PV site to the 33/132 kV Dutse Substation. It will be owned and operated by the Transmission Company of Nigeria (TCN). The interconnection facility will be financed and constructed by NSPDL. Ownership will however be transferred to TCN upon commissioning.
The project consists of advisory services to NSPDL for the completion and negotiation of a ‘Transmission Lines and Associated Substation Agreement’ with TCN.

Rwanda, Burundi - Regional Interconnection Project (220 kV Transmission Line Kigoma - Butare - Ngozi - Gitega and 220/110 kV Substations)
The project was part of the NELSAP Regional Transmission Program that aimed at interconnecting five of the Nile Equatorial Lakes Countries, i.e. Burundi, DR Congo, Kenya, Rwanda and Uganda.
The project interconnected the electricity networks of Burundi and Rwanda through the construction of a new 220 kV single-circuit transmission line with a total length of 143 km. The line will initially be operated on the 110 kV level and might later be upgraded to 220 kV.
The project also included the construction of two new 220/110 kV substations, the extension of two existing 110 kV substations and the construction of 11.2 km of 30 kV line for rural electrification of Gisagara (Rwanda).

Mauritania - Construction of Solar Hybrid Systems with 16.6 MW Solar Capacity
MASDAR is developing various small and large-scale solar and wind projects in the Pacific and other regions of the world and sourced a pool of experts to support the engineering and project management team. These support tasks are contracted separately in the form of so-called Work Orders (WO). They include feasibility studies, conceptual designs, preparation of tender documents, evaluation of bids and on- and off-site project management.
Under the current work order, all together eight hybrid systems in the range up to several MW per site and with at total solar capacity of 16.6 MW (range from 1 to 3.4 MW) will be implemented under an EPC approach. Each power plant consists of solar PV, controller, and diesel generator.
