Republic of Maldives Ministry of Housing, Transport and Environment (MHTE) Maldives Energy Authority (MEA) State Electric Company Limited (STELCO) FEASIBILITY STUDY FOR APPLICATION OF PHOTOVOLTAIC POWER ON MALE’ AND HULHUMALE’ ISLANDS IN THE REPUBLIC OF MALDIVES FINAL REPORT NOVEMBER 2009 JAPAN INTERNATIONAL COOPERATION AGENCY YACHIYO ENGINEERING CO., LTD SHIKOKU ELECTRIC POWER CO., INC. PREFACE In response to a request from the Republic of Maldives, the Government of Japan decided to conduct the Feasibility Study for Application of Photovoltaic Power on Male’ and Hulhumale’ Islands and entrusted to the study to the Japan International Cooperation Agency (JICA). JICA selected and dispatched a study team headed by Mr. Tadayuki Ogawa of Yachiyo Engineering Co., LTD. (yec) and consists of yec and Shikoku Electric Power Co., INC. four times between February and November, 2009. The team held discussions with the officials concerned of the Government of Maldives and conducted field surveys at the study area. Upon returning to Japan, the team conducted further studies and prepared this final report. I hope that this report will contribute to the promotion of this project and to the enhancement of friendly relationship between our two countries. Finally, I wish to express my sincere appreciation to the officials concerned of the Government of Maldives for their close cooperation extended to the study. November 2009 Atsuo Kuroda Vice President Japan International Cooperation Agency Mr. Atsuo Kuroda Vice President Japan International Cooperation Agency LETTER OF TRANSMITTAL November 2009 Dear Sir, It is my great pleasure to submit herewith the Final Report of “The Feasibility Study for Application of Photovoltaic Power on Male’ and Hulhumale’ Islands in the Republic of Maldives”. The Study Team conducted field surveys in Maldives over the period between February and November, 2009 according to the contract with the Japan International Cooperation Agency (JICA). The Study Team compiled this report, which consists of the Technical, Economic and Financial Feasibility Study to introduce Grid-connected Photovoltaic (PV) System, Detail Design for Pilot Project, examination on Value-added Measures, and Long-term Action Plan, etc. through close consultations with officials concerned of the Government of the Republic of Maldives and other authorities concerned. In addition to compiling this report, technical transfer and human resource development have been conducted through collaboration work with counterpart engineers in Maldives, and counterpart training at concerned organizations in Japan for the capacity development in planning and designing of Grid-connected PV system. On behalf of the Study Team, I would like to express my sincere appreciation to officials concerned of the Government of Maldives and other authorities concerned for their cooperation, assistance, and heartfelt hospitality extended to the Study Team. We are also deeply grateful to the Japan International Cooperation Agency, the Ministry of Foreign Affairs, the Ministry of Economy, Trade and Industry, and the Embassy of Japan in Sri Lanka for their valuable suggestions and assistance during the course of the Study.
