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.

③Energy Consumption6) EMS Technologies

Process of managing the consumption of energy, generally to

optimize available and planned generation resources.

It includes HEMS, BEMS, FEMS, and Demand Response.

AMI refers to a system that integrates smart meter and various

control devices for energy management. FAN is a network that

bundles multiple smart meters and connects to public

communication lines.

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.

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.
