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:
4. “Platform” to ease application service development
5. Application development

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.
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.

Demand supply balancing rules
・ 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.

Supply Side Management VS Demand Side Management
Deliver efficiency on energy usage to Demand Side
Connect multiple and different devices by IP network
Integrate it as one system・・HEMS, BEMS, CEMS、e.t.c
Develop a new business model・・Aggregator, PPS, e.t.c.
Demand for Energy Management System
Control of Demand - Energy Conservation, Demand Response
Simultaneous optimization on both demand and supply sides minimizing cost and maximizing social
Switch from “Megawatts” to “Combining Negawatts with Megawatts” by introducing “Demand Response

Saving from DR
New business model: Aggregator who integrates smart houses
Commercial-scale Utility Customers
BEMS is in business so that every user has big demand
Small and Medium-sized
Low Voltage Consumers
〔Number of Meters〕
About 180 GW
○ In the layers such as “Small and Medium-sized Enterprise” and “Low Voltage Consumer”, every
demand and consumption is small
○ Thus, aggregation is important to make scalable till the appropriate size for commercialization

• Specifies OSI Layer 5 - 7
• Communication Address is
“MAC Address” or “IP Address”.
• IP based, Media Free, and IEC Standard
– ECHONET Lite is IP based interface and interoperable to any standardized medias.
• Open Standard
– ECHONET-Lite, owned by ECHONET Consortium, has become open interface since on Dec 21, 2011.
ECHONET-Lite is recommended as the standard interface for connecting appliances and smart meter.
Communication protocol between HEMS and devices should be based on IP.
“ECHONET Lite” [IEC Standard] enables the internet of things
