FeasibiIity Study on BobovdoI Thermal Power Plant Upgrading Project March 2001 New Energy and Industrial Technology Development Organization(NEDO) usted To :Tokyo Electric Power Company Feasibility Study on Bobovdol Thermal Power Plant Upgrading Project Entrusted to: Tokyo Electric Power Company March 2001 Purpose of the study : The purpose of the study is to recover remarkably aged Bobovdol Thermal Power Plant located in the suburb of Sofia, Bulgaria, to meet the level of output that was available when it was newly built. This will be accomplished by introducing cutting edge technology available in Japan and implementing a combined cycle power generation system using a highly efficient gas turbine as a substitute. It is also aimed to implement F/S for the project to reduce carbon dioxide emission, so that it can be applied for the future joint implementation project* (JI) with Japan. NEDO-IC-00ER11 FeasibiIity Study on Bobovdol Thermal Power Plant Upgrading Project March 2001 New Energy and Industrial Technology Development Organization (NEDO) Entrusted To :Tokyo Electric Power Company March 31, 2001 Tokyo Electric Power Company Introduction The report includes results of the basic study on the development including joint implementation project for the “Improvement Project for Bobovdol Thermal Power Plant” entrusted to Tokyo Electric Power Company (TEPCO) by New Energy and Industrial Technology Development Organization of Japan (NEDO) as the project of the year 2000. Repair work plan for Bobovdol Thermal Power Plant located in the suburb of Sofia, Bulgaria (approximately 60km southwest of Sofia) has been drawn up aiming at energy saving and reduction of greenhouse effect gas. The report also provides results of the Field Study including field surveys on estimated effects of greenhouse effect gas reduction and energy saving upon implementation of the plan as well as costs required for the improvement. We also would like to express our gratitude to staff members of the Bulgarian Government ’s State Agency for Energy and Energy Resources (SAEER) and Bobovdol Thermal Power Plant for their considerable cooperation provided during field surveys and discussions conducted for the preparation of this report.
