Doing our utmost to fulfill our mission of Message from the President On behalf of Kansai Electric Power, I would like to express my sincerest condolences to all of those who were affected by the recent Great East Japan “serving customers and communities” Earthquake and to let you know that we are all praying for the earliest possible recovery of the region.
Since that earthquake, the accident at Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Station has significantly shaken people’s faith in the electric power industry, and in nuclear power in particular. We who do business in the electric power industry are deeply cognizant of the grave nature of this situation.
Due to delays in the remobilization of nuclear plants that have been undergoing inspections nationwide, the electric power supply situation this winter is expected to prove challenging, compelling us to ask once again, as we did this summer, for our customers’ cooperation in trying to conserve electricity. Again I must apologize for the considerable inconvenience and trouble that this causes for everyone.
We are doing everything in our power to ensure the safety of our nuclear power business, and are taking all possible steps to ensure the stability of our electric power supply. We are doing our utmost to restore people’s faith in the electric power industry and in nuclear power in particular, one step at a time.
The Kansai Electric Power Group is utilizing its combined strength to continue fulfilling is unwavering mission of “serving customers and communities.” We ask for your continued support and cooperation going forward.
President and Director Makoto Yagi
