ADR Demonstration Project Begins in Japan

powerlines-clouds-energy-manageSince the Great East Japan Earthquake of March 2011, there has been demand to establish systems that enable the stable supply of electric power and build mechanisms for more efficient power use, even when electric power supply and demand are constrained. Kyocera, IBM Japan and Tokyu Community will start a demonstration test of an automatic demand response (ADR) network this month.

The test, which adopts the OpenADR 2.0 Profile b international standard, is Japan’s first demonstration test that will automatically execute several steps for power optimization, including sending a power-saving request (DR signal) when electric power supply and demand become constrained, providing DR signal reception in homes and businesses, controlling electric power optimization via energy management systems (EMS) and sending reports of DR results.

The test includes 25 demonstration sites, including Kyocera’s Yokohama Office, nine commercial facilities and 15 general residences.

Upon receiving the instructions of a DR signal, each site controls its EMS-compatible equipment, such as lighting, air conditioning and storage batteries, to restrict and optimize electric power usage. Power-saving results at each facility are then organized and fed back to electricity providers.

Establishment of this ADR mechanism will allow electricity providers to accurately calculate electric power usage in real time to reduce surplus electric power and facilities and control investments. As consumers can also receive financial incentives for responding to power-saving requests and energy-saving activities, the resulting savings may also positively impact the electricity retail market.

The test is being conducted as part of an ADR collaborative demonstration by Waseda University at the EMS Shinjuku Demonstration Center. The testing period will last until March 2015.
