Toshiba's Initiatives for Reconstruction and Power Saving

Toshiba Group will contribute to rebuilding Japan and saving electricity across a wide range of areas, including the provision of diverse products and services, electricity and energy conservation efforts at production sites and the sharing of power-saving tips with customers.

Provision of products and services to help recover from the earthquake and conserve electricity

Support for earthquake recovery and reconstruction

Since the March 11, 2011 earthquake, Toshiba Group has striven with all its resources to ensure the safety of the stricken Fukushima Daiichi Nuclear Power Station (for details, see page 29 of this report and page 37 of the CSR Report 2013) and supported disaster recovery and reconstruction by fully utilizing its wide range of business domains, from social infrastructure systems to household appliances and digital products.

In accordance with Ishinomaki City's "Eco Safety Town Concept," we are promoting the development of a smart community that aims to realize a safe, secure, and environmentally conscious town where residents can use electricity even when a disaster occurs, chiefly by developing a regional energy management system (EMS) and installing photovoltaic power generation systems and storage batteries*1. The concept behind this project is to create a low-carbon eco-town and develop a safe and secure community where power supply and information flows are not disrupted even when a disaster occurs. Toshiba Group is making the most of the know-how it acquired through the Yokohama Smart City Project (YSCP) to develop a community where renewable energy is used in order to achieve greater energy efficiency during normal times and to ensure power supply and information flows are not disrupted even when a disaster occurs so that residents can live with a sense of security.

This was chosen by the Ministry of Economy, Trade and Industry (METI) as one of its FY2011 projects to promote the introduction of smart communities using the subsidies for such projects. METI invited applications from the public for the subsidies, and in April 2012, Toshiba Group, together with Ishinomaki City and Tohoku Electric Power Company, applied by submitting a project to construct a smart community within the city.

Supporting reconstruction projects

[Image] Developing disaster-resistant communities through smart solutions

Toshiba Group supported a project plan of Fukushima Reconstruction Solar Co. (which is engaged in power generation and regional exchanges to help reconstruct Fukushima Prefecture), invested in the firm, and cooperated with the firm in constructing a photovoltaic power station*1. In March 2013, Minamisoma Solar Agri-park was completed. This park supplies electricity generated at photovoltaic power stations to plant factories and sells surplus electricity to other parties. In order to support children's development, effective use is made of the photovoltaic power station and plant factories to offer "Green Academy" classes, which enable children to learn through hands-on experiences. In these classes, children (mainly elementary school students from the city of Minamisoma) experience charging of electric vehicles and the most advanced form of agriculture at a factory while learning how power is generated using natural energy. In addition, Toshiba is supporting reconstruction projects based on the New Madeina Village Plan*2 of Iitate Village, Fukushima Prefecture. In addition to cooperating with project managers in developing a master plan to promote industry for job creation and to develop a foundation for the lives of local residents, we are also considering ways of actualizing the plan, such as by generating power using renewable energy, controlling energy use in the village, and developing such control into viable businesses.

This photovoltaic power station has been constructed by Fukushima Reconstruction Solar Co. using its own funds and subsidies from the Ministry of Agriculture, Forestry and Fisheries (for emergency projects to promote utilization of resources in rural communities, such as small-scale water power).

"Madei," a word in the dialect spoken in the Fukushima region since ancient times, means "kind and thoughtful," "sparing no effort," and "wholehearted." "Madeina Village" refers to a village where the meaning of "madei" is realized.

Actions for electricity conservation

Toshiba Group provides a wide variety of products and services that contribute to energy and electricity conservation. Among these are PCs and electric fans with power peak-shift functions, which switch over to built-in batteries for power when electricity demand peaks; home fuel cells which can be used for power generation at home and that continue to generate power even in the event of a power failure; storage battery system which are effective in conserving electricity during times of peak power demand; LED lamps; and cloud computing services, which make power consumption visible.

eneGoon is a stationary home storage battery system that has a capacity of 6.6 kWh and a maximum power output of 3.0 kVA*1. It can be rapidly charged in about two hours. This storage system not only supplies electricity to electrical appliances in the home*2 but also responds to sudden power failures and helps reduce power consumption during peak hours by using electricity that was stored at night*3 during the daytime when demand is high. When combined with photovoltaic power generation or an HEMS, eneGoon contributes to daily power saving and reduction of CO2 emissions.

CAONS has been developed by applying the mechanism of heating pumps widely used for air conditioning purposes to effectively employ unused heat generated from the production process. It is the industry's first*1 air-cooled heating pump that enables users to take 90-degree hot water and achieves a high coefficient of performance (COP), 3.5*2. Due to its compact design, several CAONS units can be installed separately near processes that require them, thus minimizing heat loss during conveyance.

This heating pump reduces energy consumption by more than 60% compared to the previous systems, contributing to substantial energy conservation and reductions in CO2 emissions.

This value was obtained under the following conditions: 60° on the hot water intake side, 65° on the outlet side, 25° on the dry-bulb thermometer, and 21° on the wet-bulb thermometer (on the assumption that the heating pump has been installed indoors).

Reducing electricity use at production sites

All business and production sites of Toshiba Group have been continuously striving to conserve electricity since the 2011 earthquake. Toshiba Group continued to remove some fluorescent lamps, set air conditioning temperatures higher, stop some elevators, and take other power-saving measures as it did immediately after the earthquake. At the same time, in addition to actively introducing energy-saving equipment, such as LED lighting and high-efficiency air conditioning systems, the Group reviewed cleanroom operating methods such as set temperatures, humidity, and differential pressure and installed high-efficiency power machinery and manufacturing equipment. In FY2012, by taking these and other measures, it reduced peak power consumption by 13.9% (annual average rate) compared to the FY2010 level and total power consumption by 9.1% compared to the FY2011 level. In the future, Toshiba Group will continue to conserve electricity and energy.

Saving power throughout an entire production site by making power consumption visible

Nishishiba Electric Co., Ltd. is accelerating power-saving efforts throughout its entire production site by making power consumption visible. The company measured power consumption for all plant equipment daily and adjusted operation by simulating electricity demand. As a result, in FY2012 it reduced summer peak power consumption by 30% and total summer power consumption by 279 MWh (12%) compared to the FY2010 level.

Introducing tips for power-saving

Toshiba posts articles on its website which suggests ways of cleverly using the power-saving functions of products primarily designed for home use, such as PCs, TV sets, air conditioning systems, refrigerators, and washing machines with dryers. Tips for power-saving are given for each product. In addition, the website provides detailed information on power saving for PCs and Blu-ray disk recorders. For example, power-saving measures for PCs include eco-mode, which enables users to optimally conserve electricity using Toshiba's proprietary eco-utility functions, and Toshiba peak-shift control. For Blu-ray disk recorders, available functions include energy-saving standby functions, which reduce power consumption during time periods other than those set for instant activation, and Auto Off functions, which automatically switch the recorder off when it is not in use.
