21 Demand-Supply Verification Committee The committee, run by The National Policy Unit (NPU) which reports directly to the prime minister, verified the demand-supply balance of Japan s 9 power systems in which all the nuclear plants are stopped due to the nuclear failure in the Great East Japan Earthquake and the following tsunami. The Various countermeasures including Energy Efficiency, demand curtailment, demand response, cooperation of demand sector, restart of old generators, utilization of interconnections were verified quantitatively. The final report was published in the May, (GW) 30 Demand-Supply Balance including Pumped Storage (Kansai System) Report of the Demand-Supply Verification Committee 21

22 Cost Verification Committee:Generation cost The committee is run by The National Policy Unit (NPU) which reports directly to the prime minister. The generation cost of various generation technology including nuclear, coal, LNG, oil, wind, PV, geo, biomas, CHP are analyzed for 2010, 2020 and The methodology and the data are published on a web. Report of the Cost Verification Committee 22

23 Cost Verification Committee: RES Potential and recoverable resource The committee studied not only the cost but also the RE resource potential, economically feasible deployment. Report of the Cost Verification Committee 23

24 The interim report of the Interconnections Reinforcements Master Plan Hokkaido Honshu (600MW) Hokkaido P. Co. Area MW MW Note 1) The figures in ( ) are the heat capacity of interconnections 機密性 2 The committee reported the basic plan of prioritized transmission system reinforcements, from the viewpoints of energy security and acceleration of RE generation deployment as follows: <50Hz/60Hz Interconnection> Additional 900MW ( the total of 2100MW) will be targeted by Further 900 MW expansion will be targeted as early as possible. <Hokkaido-Honshu Interconnection > Existing expansion (from 600MW to 900MW) will be completed as early as possible. The further expansion will be studied In relation to the wind deployment in Hokkaido Island and related reinforcement of transmission lines within the area. <Reinforcement of Soma-Futaba Interconnection The reinforcement plan will be studies in relation of the wind deployment in the northern area and reinforcement of Hokkaido-Honshu interconnection. <Other interconnections> he study will be continued including flexible interconnection operation in case of emergency. Kyushu P. Co. Area MW MW Chugoku P. Co. Area 万 kw 万 kw Chugoku- Kyushu (5560 MW) Shikoku- Chugoku (2400 MW) Shikoku P. Co. Area MW MW Hokuriku P. Co.

Area MW MW <Local T/L system> The political assistances measures will be discussed for the prioritized area for wind deployment. 2) The figures for each control area are peak loads in 2010 and

25 Transmission Expansion for Wind Deployment 機密性 2 In Japan, the wind resources (on shore) are rich in limited areas such as Hokkaido and Tohoku in the northern area. In these areas, due to the lack of transmission system, the wind deployment is constrained. In 2011, there was a total of wind integration application of1870 MW in Tohoku area and 3240 MW in Hokkaido area, respectively. The cost of transmission system including interconnections were calculated as follows: Additional Wind Deployment Hokkaido (Wind and M solar) Tohoku (Wind) Total 2700 MW 3200 MW 5900 MW Regional Transmission Lines 2,00 B yen 70 B yen 270 B yen Interconnections 500 B yen B yen 900 B yen Total 700 B yen 470 B yen 1170 B yen [approx.10yen/kwh] Reinforcement of the transmission system should be planned in parallel with the increased flexibility of existing generation, curtailment RE generation, batteries and other countermeasures.
