英文要約Title: FY2013 interim annual report of Japan - US Island Smart Grid Demonstration Project (FY2011-FY2015)
(FY: Fiscal Year)

In FY2013, Mizuho Bank conducted a temporary cost-benefit analysis and brief research on a business model of the current smart grid project and additional functions of the project. Mizuho also cooperated with local organizations for EV promotion.

1. Matter and achievement of the demonstration (FY 2013)
(IV) Comprehensive research

(iii) Economic assessment of a developed system

-Quantitative evaluation of benefit of the additional functions (VPP and V2G) of the project to Maui society
-Review of the cost-benefit items selected in the preliminary research and the FY 2011-2012 research, and update of the items based on the additional functions and the project status

-It was revealed that installation of the VPP, V2G and other smart grid components brings in maximization and promotion of renewable power utilization. This means achievement of Hawaii’s renewable energy target and reduction of the petroleum purchase in Hawaii.
-It was indicated that effective renewable power utilization resulted from installation of the VPP, V2G and other smart grid components also brings in avoidance of construction of new thermal power units and reactivation of old thermal power units.

(iv) Development and validation of a business model of a low-carbon society system in Maui

-Draft of the service contents and business schemes of future business operator based on the expansion of the project component
-Quantitative preliminary evaluation of the two players’ benefits (MECO and EV users) which are sources of earnings of the business operator based on draft of the business model in Maui
-Preliminary analysis of the fair fees of those service contents
-Survey of brief description and current status of the charger business operator in the mainland

-It was revealed that certain amount of EVs should be managed to operate the service based on VPP and V2G. It was also revealed that EV related services (ex. EV charging service, EV rent-a-car, EV car sharing) are effective to gather and manage certain amount of EVs.
-We conducted the preliminary quantitative evaluation of the number of EV units and benefit of MECO and EV users based on some precondition about system operations, power plant operations, and EV behavior.

(v) Development and validation of a business model of a low-carbon society system for isolated islands
- Re-Listing up regions where the isolated island model would be applicable
-Organization of the conditions required to adopt a business model without the "isolated island" condition that would be developed hereafter

a) Examination of EV promotion measures in collaboration with local organizations
-Report the research results and status to local organizations
-Have a meeting with management of some local leading hotels to clarify situations of owned EVs and normal charger, and need or investment plan for EV quick charger.
-Have a meeting with the University of Hawaii Maui college to share information about this demonstration status and local trends
-Have meetings with HECO and MECO as needed to share information about this demonstration status, local electric business challenges, countermeasures and future outlook

b) Preliminary research of applicability of the developed business model to other regions
-Re-Update of basic information about local power infrastructures and utilities in the regions recognized as “the island business model would be applicable” in the (v)
