NEDO-IC-99R07 Feasibility Study on the St. Petersburg City Heat & Electric Cogeneration Plant No.2, etc. Scrap & Build Project March 2000 NEDOBIS E99007 New Energy & Industrial Technology Development Organization 020004894-0 Contractor: Mitsui & Co., Ltd. St. Petersburg City Heat & Electric Cogeneration Plant No.2, etc. Scrap & Build Project Contractor: Mitsui & Co., Ltd. March 2000 Purpose of the Study In accordance with the United Nations Framework Convention on Climate Change, the Japanese government plans to achieve its reduction target of green house gas emissions through various approaches, including the participation in Joint Implementation projects among advanced nations. As part of such plans, Mitsui & Co, signed a protocol with LENENEGRO (Leningrad Province Public Electric Power Corporation) concerning surveys on St. Petersburg City Central Heat & Electric Cogeneration Plant (hereinafter referred to as "Central Heat/Electric Cogeneration Plant"). The Central Heat/Electric Cogeneration Plant began operating in the 1910s. With its facility and equipment being severely antiquated, the plant's efficiency and operation rate are dropping considerably in recent years. The modernization of the plant is urgently needed. This survey project intends to improve the efficiency of the plant and reduce its emissions of green house gases by scrapping superannuated equipment and building a new gas combined cycle cogeneration facility._________________________________________________________________________ NEDO-IC-99R07 Feasibility Study on the St. Petersburg City Heat & Electric Cogeneration Plant No.2, etc. Scrap & Build Project March 2000 New Energy & Industrial Technology Development Organization Contractor: Mitsui & Co., Ltd. Preface In December 1997, the third session of the United Nations Framework Convention on Climate Change (COP3) was held in Kyoto, Japan. At this session, the parties to this convention adopted Kyoto Protocol to prevent global warming caused by the emission of carbon dioxide and other green house gases. Under the Protocol, the developed country parties agreed to aim at reducing their respective emission levels at least by 5% from 1990 levels during the period between 2008 and 2012. Japan's emission reduction target was set at 6%. In order to provide some flexibility in achieving the targets, Kyoto Protocol stipulated the inclusion of the results from Joint Implementation (JI) and Clean Development Mechanism (CDM). JI is a program in which the reduction amount of greenhouse gases is shared among developed countries that participated in specific joint projects to achieve such reduction. CDM is a cooperation between developed and developing countries. Japan plans to actively participate in these programs to meet its target. New Energy and Industrial Technology Development Organization of Japan (NEDO) offers a feasibility study assistance program for Japanese corporations that try to examine the details of such projects that help the reduction of greenhouse gas emissions through the adoption of Japanese technologies for energy conservation and alternative energies to petroleum and that contribute to the sustainable economic development of the recipient countries of such projects. Mitsui & Co., Ltd. was entrusted by NEDO to study the feasibility of the joint modernization project of the Heat/Electric Cogeneration Plant No.2 in St. Petersburg City and other facilities in the Russian Federation. This document was drafted to report the findings of our site surveys and analysis afterwards. We sincerely hope that this study will help Japan's efforts in preventing global warming through Joint Implementation and contribute to the reduction of greenhouse gas emissions and vitalization of the electric power industry in Russia.

Protocol concluded at the third visit Outline Outline of the Project The "Central Heat-Power Station" which is the target of this study, is a general name for three heat/power generation plants situated in the central part of St. Petersburg City. This Station is operating since 1897, actual facilities are manufactured between 1931 - 1985, although the power generation capacity was originally designed at 109 MW, the facility of this station is so antiquated that it is able to supply only 80% of the capacity at the most with its heat efficiency being extremely low. Supply shortages are currently supplemented by other heat/power stations in neighboring areas. The survey team visited and studied relevant sites between September 23 and October 2, 1999 and again for a 16-day period beginning on December 7, 1999. The team drafted an improvement plan afterwards and presented it to the Russian counterpart (LENENEGRO, a parent entity of the Central Heat-Power Station) during the period between February 28 and March 4, 2000. Based on discussions with LENENEGRO representatives, it was decided that the proposed combined-cycle cogeneration facility would contain three 67MW-class gas turbines, three heat recovery steam generators (HRSG), and one back-pressure turbine to achieve the generation capacity of approximately 200MW and heat supply capacity of 200G cal/hr. The total investment required for this project is about 140 million dollars. The construction work is estimated to take 36 months. It is estimated that the implementation of this project will reduce 1,481,979.0 tons of CG2 per year, or a total of 40,013,434 tons in 27 years after the commencement of operation. In addition, the generation terminal efficiency will be improved from the current 18.68% to 41.0%, which translates into an annual saving of 546,301 tons of crude oil or its equivalent. Since the currency crisis in July 1998, domestic consumer prices have been kept low in relation to the depreciated Rubles. This has been particularly true with electric and heat charges in comparison with international standards, as they are the necessities of economy and life. Therefore, at the current exchange rate, the financial feasibility of this project would be very low. 8.582% FIRR after tax would be regarded rather low if this were a purely commercial project. However, considering the fact that it is an environmental improvement project aiming at reducing the emission of carbon dioxide, etc. to prevent global warming, the figure should be rated highly. If implemented, this project is estimated to annually reduce 6,117.51 tons of NOx , 6,146.57 tons of SOx , 1,571.78 tons of soot, and other environmental pollutants. It will become a model plant for urban-type heat-power stations in Russia and provide a foothold in disseminating new technology to other plants, thereby spreading more efficient combined- cycle generation equipment throughout Russia. In recent Russia, greenhouse-gas emission has dropped dramatically since 1990 due to economic recession.
