KYOCERA Selected to Test ADR System for Improving Electricity Management in Japan
Test for a rapid and precise system to optimize power supply and demand positions Kyocera as potential aggregator for Japan’s new “negawatt” exchange market
Schematic of Kyocera ADR test
Kyocera is testing its ADR system as an electricity aggregator (intermediary company between electricity providers and end users) by controlling equipment such as power generators, air-conditioning equipment and storage systems at multiple supermarkets and manufacturing facilities. Kyocera’s goal is to develop a rapid and precise ADR system to help facilitate Japan’s “negawatt” exchange market planned to open in 2017 — where end users can sell the amount of electricity that they have saved based on power-saving requests as “negawatts.”
Since the Great East Japan Earthquake of March 2011, Japan has sought to reduce reliance on large-scale electricity sources and utilize renewable energy. Due to the significant growth in renewables in recent years, the Japanese government began supporting various projects to help establish technologies for virtual power plants. If they can operate like a single large power plant, integrating renewable power generation, energy storage and demand-side measures such as demand response, then it can be used as a solution to effectively utilize renewable energy. The government program hopes to establish control technologies for virtual power plants exceeding a total of 50MW during a period of five years, and to encourage further implementation of renewable energy.
With the aim of developing technologies to automatically optimize electric power supply and demand, Kyocera has carried out multiple demonstration projects on ADR in Japan. The company participated in a collaborative demonstration with two other companies at 25 sites from October 2014 to March 2015, confirming the control flow applicable to demand response for residential facilities to determine the amount of power saved. A second demonstration project was carried out from April 2015 to March 2016 at 12 sites including supermarkets and manufacturing facilities to validate the effectiveness of an automated system for fast demand response and feasibility of a “negawatt” exchange.
Summary of Kyocera’s new Automated Demand Response test project:
|・||Overview: Utilizing its observations from past tests, the goal of Kyocera’s new demonstration project is to develop and assess the effectiveness of a rapid and precise ADR system, enabling the creation of “negawatts” with no shortage and control of surplus “negawatts.” Based on power-saving requests from TEPCO Power Grid, Incorporated, Kyocera’s “POM SYSTEM®,” a comprehensive energy management system, will control energy-related equipment installed at demonstration sites to reduce the amount of electricity purchased. The system may automatically operate power generators, turn down air-conditioning equipment and discharge power from storage systems to reduce electricity used.|
|・||Time Period: August 2016 - January 2017|
|・||Field: 10 sites consisting of supermarkets and manufacturing facilities in Japan’s eastern region|
Development of Kyocera’s Energy Business
Kyocera’s development as an electricity aggregator represents a new milestone in the company’s energy business, which began from the research on solar energy in 1975. Since then, the company has expanded its energy business to the construction and operation of solar power plants, and also markets lithium-ion batteries and Home Energy Management Systems (HEMS) in Japan. In addition to this new test, Kyocera recently participated in a separate collaborative demonstration test with two other companies as an equipment supplier, which integrates multiple homes as virtual power plants (planned between July 2016 to February 2017 in the Tokyo, Chubu, and Kyushu regions of Japan). By providing and managing residential battery storage systems and HEMS in this test, the company aims to further cultivate expertise and develop residential equipment suitable for virtual power plants. Based on its comprehensive strength, Kyocera will further expand its energy business, helping to facilitate an energy-efficient society.
