SGCG: Smart Grid International Plenary Smart Grid Standardization -Implementation Plan in Japan- Koichi NODA Director, Technical Regulations, Standards and Conformity Assessment Policy Division, Ministry of Economy, Trade and Industry , Japan Monday, 18 June 2012 Copyright © IEC, Geneva, Switzerland Outline for today 1. Japan’s situation on Energy 2. Japan’s Roadmap 3. Current Status in Japan 4. Relationship between standards and regulations Japan’s situation on Energy Before the Great East Japan Earthquake High reliability of power distribution grid No urgent need for improvement of grid After the Great East Japan Earthquake Problems we are facing -Energy supply shortage Lack of energy capacity All nuclear power plants were shut down on 5th May 2012. Need to reduce electricity consumption ‘Electricity Supply-Demand Measures this Summer’ was prepared by the Electricity Supply-Demand Review Committee and the Energy and Environment Council on May 18,2012. １ Japan’s situation on Energy Challenges How to avoid rolling blackout? Further promotion of energy efficiency Broad introduction of renewable energy How to ensure adequate supplies of energy during disasters? Need to disseminate the idea of “Smart Grid” and “Smart Community” 2 Japan’s situation on Energy How to ensure stable voltages, frequencies and other such issues of electricity quality. Companies launch products whose sales point is safety.

Low dependence on grid- connected power (distributed control) 4 Japan’s situation on Energy Summary of the Feed-in Tariff Scheme for Renewable Energy Electric utilities will be obliged to purchase electricity generated from renewable energy sources - Photovoltaic, wind power, Small and medium scale hydraulic power, Geothermal power, Biomass - fixed price : per 1kWh ￥42～￥ 57.75（TBD) - fixed-period contract : 10～20years（TBD) Surcharge for renewable energy Start : July 1st, 2012. 5 Japan’s situation on Energy Summary of the Feed-in Tariff Scheme for Renewable Energy Sale of electricity from Those engaged in the renewable energy sources Electricity supply power generation business using renewable energy sources Electric utility Purchase of electricity at a fixed price Collection of Electricity for a government surcharge together with specified period the electricity charge customers Deliver of Submission of purchase cost collected surcharge Genki-kun No. 1, symbol of “Tsuru City, Town of Water” Cost bearing adjustment organization (Organization to collect and Specification of distribute the surcharge) purchase price and purchase period Decision of Surcharge unit price per kWh Those who generate power at home Approval of facilities Procurement price calculation committee Government (appointment of five committee members requires consent by the Diet) 6 The role of standards in Smart Grid Smart Grid is “System of systems”. Interoperability makes it possible for smart grid to work securely and effectively. Standards are essential enabling to have interoperable systems and components.
