Supplying Electricity to Customers (Electricity System)
Create (Generation) Send (Transmission and Distribution of Electricity) Use (Demand)
Generation Facilities Transmission Facilities Distribution Facilities Customer Facilities
The electricity system is the platform that matches the “power demand” of customers in remote areas with “power generation” via transmission and distribution networks.

Energy Imports under CO2 Net Zero Emissions
CO2-free Energy Can Japan be economically self-sufficient? Should Japan import part of its energy from abroad? Biomass Fuel (Tankers) CO2-free Electricity (International Grid
Connection) CO2-free Hydrogen (Tankers/Pipelines)

？
Expected Roles of International Grid Connection
1. Imports of Non-carbon Electricity Required capacity will be reduced as progress is made in
decentralization of energy supply.
Competition with hydrogen transportation, etc.
2. Expansion of Flexibility in Energy Supply & Demand
Overall reduction of the need for flexibility resources as fluctuations in supply and demand are averaged out through wider-area networking
Competition with energy storage devices (including EV and heat-pump hot-water supply)
Important to compare economic efficiency with other alternative
means and to secure redundancy by connecting with multiple countries.
