No. OUTLINE DESIGN STUDY REPORT ON THE PROJECT FOR CONSTRUCTION OF DIESEL POWER STATION IN SAMAWAH IN IRAQ JUNE 2005 JAPAN INTERNATIONAL COOPERATION AGENCY GRANT AID MANAGEMENT DEPARTMENT G M J R 05 - 064 PREFACE In response to a request from the Government of Iraq, the Government of Japan decided to conduct an outline design study on the Project for Construction of Diesel Power Station in Samawah and entrusted the study to the Japan International Cooperation Agency (JICA). JICA sent to Amman, Jordan a study team in two times; from November 17 to December 7, 2004, and from February 15 to 28, 2005. The team held discussions with the officials concerned of the Government of Iraq, and conducted a field study at the study area through a local consultant. After the team returned to Japan, further studies were made. Then, a mission was sent to Amman, Jordan from May 7 to 14, 2005 in order to discuss a draft outline design, and as this result, the present report was finalized. I hope that this report will contribute to the promotion of the project and to the enhancement of friendly relations between our two countries. I wish to express my sincere appreciation to the officials concerned of the Government of Iraq for their close cooperation extended to the teams. June, 2005 Seiji Kojima Vice President Japan International Cooperation Agency June, 2005 Letter of Transmittal We are pleased to submit to you the outline design study report on the Project for Construction of Diesel Power Station in Samawah in Iraq. This study was conducted by Nippon Koei Co., Ltd, under a contract to JICA, during the period from November, 2004 to June, 2005. In conducting the study, we have examined the feasibility and rationale of the project with due consideration to the present situation of Iraq and formulated the most appropriate outline design for the project under Japan’s grant aid scheme. Finally, we hope that this report will contribute to further promotion of the project. Very truly yours, Noriaki Matsushima Project manager, Outline design study team on the Project for Construction of Diesel Power Station in Samawah Nippon Koei Co., Ltd.

The survey team collected relevant information from the authorities of Iraq, CPA, and Iraqi local consultants, then prepared a short list of the prospective projects with their preliminary designs and cost estimates. Among the shortlist, implementation of seven projects of grant assistance were decided and announced by the Government of Japan. Meanwhile, in order to evaluate the possibility of projects such as mobile power station as subsequent grant assistance, JICA conducted Preliminary Study for Reconstruction of Iraq (Phase 3) form August until October, 2003, upon the request by the Government of Japan. During the above study, it was turned out that supply of natural gas by Iraqi side, which was the prerequisite condition for the mobile power station, would be difficult in Samawah. At the same time, Iraqi side strongly requested construction of a diesel power plant of 15 MW x 4 nos., which would use heavy fuel oil that was available in Samawah. The Government of Japan took the above into consideration, and for the purpose of dealing with the serious power shortage in Iraq, requested JICA to conduct additional study to evaluate the possibility of large scale diesel power plant as a alternative of the mobile power station plan. Upon this, JICA dispatched the study team for Preliminary Study (Phase 4 / Outline Design Study on the Project for Construction of Diesel Power Station in Samawah) to Amman in three times in November, 2004, February and May 2005. The study team discussed with officials from the Ministry of Electricity, the Ministry of Oil, and Muthannna Governorate in Iraq, then confirmed the contents of the requested project. Besides, the study team surveyed current situation of power supply in Muthanna Province and Samawah, and collected basic data related to propriety and possibility of the requested project with assistance of local consultants in Iraq. Based on such collected information, outline design of the project with its cost estimate was prepared. As a result of the study mentioned above, it was confirmed that due to damages by the war, power supply in whole country of Iraq is still under constraint, and this also frequently forces power outage in Samawah, Muthanna province. Under such circumstances, the Government of Iraq aims to improve power supply condition urgently by constructing and/or rehabilitating the power facilities, and thus to accelerate the reconstruction of Iraq. This project is to construct a diesel power station in Samawah city to improve the currently power shortage problem in the area. Power shortage which is serious problem at present in Samawah will be substantially improved by commissioning of the power station of the project, and stable power supply to the region inhabitants would be realized. The summary of necessary components to attain this project is shown below. (a) Construction of a new power plant (output of 60 MW). (b) Installation of 132kV interconnecting facilities and additional electrical equipment in Old Samawah substation. (c) Construction of fuel pipeline which is connected between new power station and Samawah oil refinery. (d) Relocation of existing 132kV transmission line. (e) Training for operation and maintenance. (a) Construction of a new power plant (output of 60 MW). Four numbers of diesel engine generator of 15 MW will be installed with the auxiliary equipment such as fuel oil system, lubricating oil feeding equipment, cooling system equipment, air intake and exhaust system, etc. Engine stroke type will not be restricted to either 2-stroke (low speed) or 4-stroke (medium) engine. (b) Installation of 132kV interconnecting facilities and additional electrical equipment in Old Samawah substation. For the interconnecting the new power station with the existing Old Samawah substation, two circuits of 132 kV underground power cables will be installed from the 132 kV switchyard in the new power plant to the busbar, which is to be extended, in the substation. (c) Construction of fuel pipeline which is connected between new power station and Samawah oil refinery. To transfer the heavy fuel-oil from the existing Samawah Oil Refinery to the new power station, underground type fuel-oil pipeline of about 7.5 km will be constructed. (d) Relocation of existing 132kV transmission line. Relocation of the existing 132 kV transmission line, 2 circuits of Sawa – Old Samawah section, will be executed in advance for the smooth implementation of the Project. (e) Training for operation and maintenance. The plan of the personal education and training for operation and maintenance is consisted of the following 3 stages. 1) Stage-I: Basic education 2) Stage-II: Training at manufacture’s factory 3) Stage-III: Training at Site The work execution of this project will require 20 months from the conclusion of the contract for construction to completion of the project. Items to be executed by the Iraqi authorities in case that a grant aid project from Japan is executed are as follows: (a) Assisting customs clearance at ports of entry into Iraq (b) Getting clearance from relevant authorities which may be necessary within Iraq for the execution of the Project,
