Big Data innovation in Japan’s energy industry - EBA Fieldwork 2015

  1. 1. Big Data innovation in Japan’s energy industry 0 Deputy Chairman of Smart House and Building Committee, Japan Smart Community Alliance, Japan Fellow, ECHONET Consortium Keio University Masaki Umejima
  2. 2. To be an ice breaker  • What is big data innovation? – Google has gathered a lot of personal data by providing  with many free services, e.g. G mail and Google Doc – Why google can do that?  • Big data innovation has 6 components: 1. Sensing  2. Collecting  3. Analyzing 4. “Platform” to ease application service development 5. Application development 1 6.Modeling
  3. 3. Evidence Based Approach ASEAN EBA Leader with Resilience, Innovation and Sustainability 3

  5. 5. G to G collaboration to implement Community Cloud  • Bandung city,  Indonesia and JSCA,  the industry and  government liaison to  export Japanese   infrastructure to  overseas, have signed  LOI to drive research  and business  development 5
  6. 6. Support and Cooperation Electric Utility Members Home Electronics Industry Gas Utility IT Company Heavy Electric Industry Developer Total 350 companies and associations Japan Smart Community Alliance [JSCA] g Board Meeting International Strategy International Standardization Roadmap Smart House and Building Committee 6 JSCA, government–industry liaison, has addressed DSM 6
  7. 7. What happened in Japan’s electric industry?  • Japan lost electric supply due to a big earthquake  in Mar 2011. That was 30% nation wide supply. – 30% power supply was generated by nuclear. After  Fukushima, it has become zero. 7 8.1 24.7 29.4 7.6 29.2 1.1 Water Coal LNG Gasoline Nuclear Returnable
  8. 8. What are Japan’s options? 1. Restart nuclear power plant 2. Increase coal and gasoline turbine 3. Increase returnable energy 4. Develop demand side management system 5. Open electric utility market to a new entry • Now, Japanese electric market is under regional monopoly.   In many countries, this market is state owned.   8

Business requirements of PPS demand supply balancing rules transmission network of electric power company Supply side x m Demand side x n Generated power Electricity Demand M M DB Power meter Consignment Supply Power plant for regulation M Time Demand Time Generated power JEPX (Japan Electric Power Exchange) Demand supply balancing rules Power meter Consignment Supply ・ Due to Japanʼs regulation, the volume between demand and supply must be balanced within ±3% every 30 minutes in each region of electric power companies. ・ optimal scheduling of power plant operation based on demand forecast. ・ real time control based on monitoring data of power plant and customers.
