This document provides an analysis of demand side management (DSM) technologies. It presents a diagram of the DSM system, identifying technological components like energy management systems (EMS), advanced metering infrastructures (AMI), and field area networks (FAN). The document then describes these DSM domains in more detail. Specifically, it outlines how AMI integrates smart meters and control devices to enable energy management. Finally, the document discusses how AMI facilitates communication among smart meters, service providers, billing systems, and demand response networks to support functions like real-time energy consumption monitoring.

3. Introduction
Purpose
-In the previous research, we identify the business opportunities in
Demand Side Management (DSM) that include the Energy
Management Services (EMS) and Advanced Metering Infrastructures
(AMI) & Field Area Network (FAN).
-In this research, we will deeply take a look at the structure of these
technological domains, and pick up & analyze some companies
active in these domain as case study.
Methodology
-We will present an diagram of Demand Side Management,
identifying each technological component within the system.
-We will then pick up some companies that are actively doing
businesses within these fields to get case studies for Japanese startups.

7. 3．Structure of DSM
AMI assumes communications among Smart Meter, Service Providers
including utility companies and Energy Management System placed in the
demand side.
Between service providers and consumers AMI provides information to
various systems through Meter Data Management System (MDMS). For
example, billing automation system, distribution automation system are done
through AMI.
The introduction of AMI makes it possible to
measure power consumption real time.

8. 4．Big News!
California PUC adopted the world’s first comprehensive set of rules
to ensure that consumers can access the detailed energy usage data
gathered by their smart meter. This decision calls for:
1. Web Presentment
-Utilities must provide via their websites such information as detailed energy usage.
2. Tier Alerts
-When customers move from one price tier to the next, the utilities are to provide notification.
3. Rate Option Calculator
-Help consumers understand whether they would save money by switching to a time-of-use rate.
4. Real-time Data
-Decision requires them to file plans that “include an initial phase with a rollout that enables a
minimum of 5,000 HAN-enabled devices to be directly connected with smart meters.
5. Third-Party Data Service
- Consumers can authorize third parties to receive their backhauled smart meter data directly from the
utility to support services such as energy efficiency. Will use OpenADE as standard.
