Implementation of Environmental Assessment

In constructing power stations and other structures, the environmental impact assessment (environmental assessment) for both during construction work and after commencement of commercial operation is conducted, and the environmental preservation measures are taken in order to minimize the impact on the surrounding environment.

Environmental Assessment Associated with Replacement Plan of Shin-Sendai Thermal Power Station

We have a project plan to phase out the existing facilities in Shin-Sendai Thermal Power Station and to construct 950,000-kW-class high-efficiency combined cycle power generation facilities on that site with a view to strengthening the competitiveness of thermal power sources as well as to reducing CO2 emissions.

For this replacement plan, the procedure of the environmental assessment has been proceeded with since FY2006 under the Environmental Impact Assessment Law and the Electricity Utilities Industry Law. The procedure for the environmental impact assessment methodological report is now under way, and we are now engaged in the survey of the present states of atmospheric environment, water environment, and landscaping, etc. As for Sendai Thermal Power Station Unit 4 (446,000 kW) for which the environmental assessment procedures have been conducted since FY2004, as a series of procedures are completed, we plan to start the construction in FY2007 and commence its commercial operation in FY2010.
