Mauritania - 50 MW Thermal Power Plant in Zouerate
SNIM (Société Nationale Industrielle et Minière) is a company that exploits the iron ore deposits around the mining city Zouerate, located in the Tiris Zemour region in the north of Mauritania. In order to cover its short-term electricity demand, M/s. SNIM commissioned TRACTEBEL ENGINEERING S.A. to carry out a feasibility study for a 50 MW thermal power plant in the city of Zouerate. The study on the generation units shall evaluate the following two variants:
- Conventional heavy fuel oil-fired generation units,
- Dual fuel generation units running on heavy fuel oil and natural gas.
Parts of the tasks under this feasibility study have been subcontracted to intec.

ECOWAS - Reduction of Distribution Losses in the Framework of the GIZ Project "Promoting a Climate-Friendly Interconnected Power System in West Africa"
ECOWAS, the Economic Community of West African states comprises 15 West African countries: Benin, Burkina Faso, Cabo Verde, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone and Togo. The overall GIZ project supports the regional dissemination of experience concerning renewable energies and aims at improving the capacities of utilities in the long term. The "electricity distribution" part of the project, together with selected utilities, identifies options for the reduction of distribution losses, implements exemplary measures and disseminates the results in the region.
intec's services
- Task 1: Data collection, review and analysis of current situation in the member utilities: Diagnosis on the prac-tices of loss reduction, catalogue of good practices, proposal of related initiatives/projects for each utility, ex-amination of the adequacy of existing master plans in the distribution utilities and proposal of required updates including costs
- Task 2: Study to quantify system losses: Determination of loss levels by utility, estimate of share of technical losses, preparation of mitigation measures, review of / proposal for energy audit system for each utility, preparation of indicative plans and targets for capital expenditure to reduce overall losses possibly to below 10%
- Task 3: Loss reduction investment plans and cost estimates: development and recommendation of a comprehensive short- and long-term loss reduction investment plan including costs, recommendation of technical measures such as norms, standards and loss management guidelines
- Task 4: Training and capacity building: training needs assessment of utility staff, recommendations for capacity building programs in line with WAPP's capacity building program for member utilities and in coordination with GIZ's capacity building activities of the overall project.

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 a second phase, the plant is currently extended to 180 MW capacity by addition of 4 further 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 owned and operated by the Transmission Company of Nigeria (TCN). The interconnection facility will be financed and constructed by NSPDL, but ownership will 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).
