The power situation in Japan changed dramatically with the Great East Japan Earthquake. In fiscal 2013, action on possible power shortages was demanded mainly in the service areas of Kansai Electric Power, Kyushu Electric Power, and Hokkaido Electric Power companies. Founded on energy conservation efforts that have continued for many years, we are working on power reduction in our sites, in an effort to deal with power cuts during peak periods. Specifically, we took measures suitable to the characteristics of each site, and conducted a wide range of power-saving activities from the three aspects of factories and offices, working style, and activities conducted by employees at their workplaces and homes. As a result, we were able to reduce our power consumption to meet the requests of the power companies in fiscal 2013.
In July 2011, Panasonic established the Corporate Electricity Saving Division to deal with the power shortages expected to continue long into the future, and has been accelerating measures to improve the productivity and management efficiency by making more efficient use of electricity. With the thorough entrenchment of energy-saving activities across the organization, the Corporate Electricity Saving Division was dissolved with successful results as of March 31, 2013. Power conservation efforts will continue into the future to deal with power shortages.
In our factories and offices, we implemented power-saving efforts such as “appropriately manage equipment and suspend the use of unnecessary devices,” “enhance the management of power usage,” and “extend the operating hours of in-house power generation systems, increase their capacity, and rent more systems.”
In power-saving, greater power usage visibility is an important element. Advanced technologies such as our energy display system, SE-Navi as well as diligent power-saving activities are being implemented to further enhance corporate efficiency in saving energy. Also, electric power generated by the cogeneration system at our Hokuriku Plant in the Hokuriku Electric Power service area has been classified as Deemed Power Conservation, contributing to the management of power shortages in the Kansai service area and at the same time realizing the power-saving target sought by the power utilities.
As for working style, we promoted “ensure all employees leave work on time and encourage employees to travel directly to and from the work destination without stopping by at the office,” “encourage working at home,” and “expand the ‘cool biz’ period (from May to October),” etc.
Simultaneous leave from July 23-27 was implemented at our corporate Head Office in Kadoma City, Osaka Prefecture, by moving paid leave to be taken in autumn 2012 and later back to the July period. This has contributed to reducing consumption during the power peak for Kansai Electric Power.
Activities conducted by employees at their workplaces and at home include the following: proposals for power saving ideas that can be implemented both in the company and at home; environmental e-tests featuring questions related to power conservation; and promotion of a household Power Saving Action Plan.
In power conservation, activities at the homes of employees are important alongside activities at business sites. For this reason, the Power Saving Action Plan by employees was put into effect in fiscal 2012. In fiscal 2013, 17,800 employees participated in the summer, and so did 13,200 in the winter. Comparing to the results in fiscal 2012, participants succeeded in reducing their use of electricity at their homes by about 1.6% in summer and by about 3.6% in winter, on average per household. The plan has led to successful power conservation. At the same time, a contribution of LED lights that can generate a power conservation effect equivalent to 1% of the total power saved at employees' homes was made to disaster-affected areas since the winter of fiscal 2012. Over three occasions, a total of 1569 LED lights (including extra donations) and 100 solar-powered LED lanterns were donated to Iwate, Miyagi, and Fukushima Prefectures.
