15. 10 Electric Power Companies System peak load : 178,995MW Power sales: 888,935GWh (As of March 31, 2009)

16. Fundamental Role of Electric Utilities (Simultaneous Achievement of 3Es) • It is the fundamental role of electric utilities to ensure stable supply of quality and inexpensive electricity by simultaneously achieving the 3Es—“Energy Security,” “Environmental Conservation,” and “Economy”—as set forth in the Basic Law on Energy Policy. • Electric utilities will promote CO2 emission reduction measures to attain simultaneous achievement of the 3Es, thereby contributing to building a low-carbon society. • 　→　It is important to appropriately take into account not only environmental aspects, but also energy security and economy. Stable supply of quality / affordable electricity to the customer Energy security Economy Environmentalconservation

17. In Pursuit of the “Best Mix” of Energy Sources • Japan has a fragile energy supply-and-demand structure, with few natural resources, a low energy self-sufficiency rate. To meet electricity demand that has been steadily increasing in these tens of years, continued action is taken to ensure stable supply and deal with the problem of global warming through the “best mix,” by shifting the focus of power source development from hydro through large-capacity thermal to nuclear power generation. Changes in Percentage Distribution of Power Sources of All Electric Power Companies (Generated Output Basis) Percentage of non-fossil power sources To 50% in 2020 2019plan Mainly hydro supported by thermal Manly thermal supported by hydro “Best mix” centering on nuclear Source: Summary of Power Sources Development and others. Percentages for FY2019 are based on the FY2010 supply plan.

18. Japan’s Nuclear Policy • It is very important for Japan to establish the nuclear fuel cycle project due to its poor energy self-sufficiency rate, so as to further improve the features of nuclear power generation and allow for a long-term stable electricity supply. • For example, Japan has created basic policies to continue promoting nuclear power generation and to steadily advance the nuclear fuel cycle. • Electric utilities are promoting the use of nuclear energy based on these basic policies. <Basic Policies> Framework for Nuclear Energy Policy (approved by the Cabinet in October 2005) ○It is aimed that nuclear power generation either maintain or increase the current supplied energy level - 30 to 40% of the generated output - beyond 2030. ○Utilization of materials such as plutonium and uranium recovered through spent fuel reprocessing will be included in the basic policies. ○Commercial adoption of the fast breeder reactor will begin in 2050. <Concrete Measures> Nuclear Nation Establishment Plan (August 2006) (1) Efforts to achieve a percentage of nuclear power generation at or greater than present levels over a medium to long term. (2) Steady promotion of the nuclear fuel cycle and strategic reinforcement of cycle-related tasks (3) Early commercialization of the fast breeder reactor cycle (4) Ensuring and developing robust technologies, industries, and human resources (5) Support for international development of Japan’s nuclear industry (6) Active involvement in the development of an international framework to expand nuclear power generation and ensure nuclear non-proliferation (7) Coexistence of nuclear energy and the general public / local community (8) Steady promotion of radwaste measures

19. Initiatives to Promote Nuclear Power Generation • On the major premise of public acceptance and regional coexistence, all utilities efforts will be put into maximizing the potential of existing nuclear power stations, promoting newplant construction and replacement, and establishing the nuclear fuel cycle to achieve the goal of promoting nuclear power generation. • To contribute to maintaining and expanding the world’s nuclear energy, it is important to gain international trust by continuing stable operation of domestic nuclear power stations. We will then make international contributions, taking advantage of the features of Japan’s technologies. Public Acceptance and Regional Coexistence Understanding the necessity of nuclear energy, to realize stable energy supply and a low-carbon society Utilizing existing nuclear power stations Improving safety and reliability Steady promotion of safe and stable operation Improvements toward scientific and logical regulations and systems Smooth promotion of new plant construction / addition and replacement Establishing the nuclear fuel cycle Contributing to maintaining and expanding the world’s nuclear energy International contributions taking advantage of the features of Japan’s technologies on the major premise of safe and stable operation in Japan

20. Utilizing existing nuclear power stations Current Status of Nuclear Power Generating Operations • As of the end of January 2010, 54 commercial nuclear power station units generating 4,884.7 x 104 kW are in operation. • In FY2009, nuclear power stations generated 2,785 x 108 kWh, accounting for approximately 30% of Japan’s total generated output. ［108ｋＷｈ］ ［104ｋＷ］ Generated output Figure: Percentage Distribution of Generated Output by Power Source (FY2009) Generated output Installed capacity Installed capacity Figure: Changes in Nuclear Power Station Installed Capacity and Generated Output (From JNES Nuclear Facilities Operation Management Annual Report and others)

21. Promotion of Nuclear Power Plants • Utilizing existing nuclear power stations 【ＭＷ、ＧＷｈ】 FY 2018 62 61,700 － ↑Estimated As of the end of 2009, 54 units are in operation. “Tomari nuclear power plant unit3 installed” DECLINE “Hamaoka Unit 1,2 terminated” FY [10Utilities] “Estimated”

24. Utilizing existing nuclear power stations 30th year 40th year 50th year 20 units completed※ （As of June 2010) Aging Management • Components and structures with safety functions will be subjected to integrity assessment (aging management engineering assessment) before they have been in operation for 30 years, and will assume they will be used for 60 years. Based on this assessment, a “long-term maintenance plan” will be mapped out, putting together new measures to be added to maintenance management activities. • Under the new inspection system, a “long-term maintenance management policy” (equivalent to a long-term maintenance plan” will be developed and described in the Technical Specifications for the approval of the national government. *For Tsuruga-1 and Mihama-1, 40th-year engineering assessments have already been completed.

25. Utilizing existing nuclear power stations Earthquake in Kashiwazaki-Kariwa NPS (Tokyo Electric Power Company, Total 7units; 8,212MW) • Time of occurrence： July 16, 200710:13 • Magnitude：6.8 • Depth of epicenter: 17km • Distance from power plant： Epicenter→16km Hypocenter→23km TEPCO’s actions • Seismic safety evaluations of the facilities against this earthquake based on the inspection results • conducting construction work such as support reinforcements in order to improve the earthquake safety of power stations. • Aim for a power plant that is resistant to disasters Safety functions of “stoppage”“cooling,”“containment” worked appropriately, and nuclear power safety was secured. Actions of all utilities • Seismic safety evaluations of the facilities on the existing plants • Strengthening emergency preparedness • Sharing of the lessons learned inside Japan and overseas Epicenter Update status Unit 1 (1,100MW)Commercialoperation (from Aug 4, 2010) Unit 2 (1,100MW) Regular maintenance Unit 3 (1,100MW) Regular maintenance Unit 4 (1,100MW) Regular maintenance Unit 5 (1,100MW) Regular maintenance Unit 6 (1,356MW) Commercialoperation (from Jan 19, 2010) Unit 7 (1,356MW) Commercialoperation (from Dec 28, 2009) Kashiwazaki-Kariwa NPS

26. Smooth promotion of plant construction, addition, and replacement New Construction plan of Nuclear Power Plant • Since the construction of a nuclear power station takes a long time from its planning to the start of operations, it is important to promote replacement and new construction smoothly. • To do so, it is necessary to develop a mid/long-term business environment to allow for investment in nuclear power generation.
