Adaptation measures to avoid the effect of climate change

In response to climate change issues including global warming, Toshiba Group is promoting measures to mitigate their effects by reducing GHG emissions. At the same time, we are also developing adaptation measures to prepare for the effects of climate change, such as weather radars, rainwater drainage systems, disaster prevention information systems, and hydrogen-based autonomous energy supply systems.

Case Study 1: Phased-Array Weather Radar essential to climate change adaptation

Toshiba Infrastructure Systems & Solutions Corporation

A phased-array weather radar can observe a wide area in three-dimensional space from high altitudes quickly and has performance equivalent to 20 conventional parabola radars. It can monitor rapidly growing cumulonimbus clouds in the incipient stage as well as their development thereafter. Thus, it helps reduce climate change-induced disaster risks by detecting early signs of localized torrential downpours, improving forecast accuracy, and providing prompt evacuation guidance. Phased-array radars also offer a variety of disaster prevention solutions that ensure safety and security when used in combination with rainwater drainage systems and disaster prevention information systems.

Case Study 2: Virtual Power Plant (VPP) that generates power by a set of controlling storage batteries

Toshiba Energy Systems & Solutions Corporation

Toshiba Energy Systems & Solutions Corporation is working with Yokohama City and TEPCO Energy Partner, Inc. to conduct a field experiment that aims to test a system designed to utilize storage batteries installed at local disaster prevention centers as "virtual power plants" to help electricity retailers adjust electricity demand (demand response) during normal times as well as to utilize such batteries as power sources for disaster prevention to keep telecommunication facilities operating for several days during an emergency. This field experiment aims to realize timely electricity usage to avoid excess supply of photovoltaic power and other dispersed energy. To this end, multiple storage batteries with capacities of approximately 10 kWh are controlled as a group to be charged and discharged in tandem with price fluctuations in the wholesale electricity market in real time.
