Iraq - Technical Support for the German "Credit Facility to Assist the Return of IDPs" in Iraq

Germany’s government, via the KfW, provides a credit facility (United Financial Loan or UFL) for stabilization/recovery of liberated territories, and to assist the return of Internally Displaced Persons (IDPs). Part of the project is the assistance to the Ministry of Electricity (MoE) in the preparation of an investment programme (‘investment measure’) and a related technical support component (‘accompanying measure’), to assess and plan measures for the rehabilitation of the transmission/distribution networks for re-establishing power feeders to the end users. This results in an ‘Investment Plan for the Power Sector in Northern Iraq’, consisting of Phase I for immediate implementation, then Phase II for complementary required investments.

Measures identified for Phase I include the rehabilitation of one 132/33 kV, 3 x 63 MVA GIS substations and three 132/33/11 kV AIS substations, supply of three 132/33/11 kV, 3 x 63 MVA power transformers, supply of 132 kV transmission line towers and accessories for rehabilitation of six transmission lines, supply of eight 33/11 kV, 31.5 MVA mobile substations, five 33/11 kV, 31.5 MVA power transformers and supply of distribution transformers 11/0.4 kV, different power ratings, as well as distribution kiosks and accessories.

Measures identified for Phase II include the rehabilitation of a 400/132/11 kV, 4 x 250 MV GIS substation, the construction of two new 132/33 kV, 3 x 63 MVA GIS substations, the construction of two new 33/11 kV, 3 x 31.5 MVA distribution substations and the construction of 154 km new double circuit transmission line
