Coal-Woody Biomass Co-combustion Generation at Hekinan Thermal Power Station

September 17, 2010

Chubu Electric Power Co.,Inc.

Chubu Electric Power Co., Inc. positions action on global environmental issues as one of its most important management agendas.  In addition to proceeding with the introduction of  new energy sources that have a low environmental impact, we work to achieve our obligatory targets under the RPS law(*1).

As part of these efforts, since May 2009 we have been conducting proving tests looking towards the introduction of woody biomass co-combustion at our coal-fired Hekinan Thermal Power Station.  With a test to be conducted tomorrow (September 18) in Unit No. 1 for approximately four days, we will have completed proving tests in all of the units, and intend to shift to full-fledged co-combustion.

We believe that this shift to full-fledged coal-woody biomass co-combustion will reduce our CO2 emissions by approximately 200,000-300,000 tons per year.

Chubu Electric will continue to actively work to resolve environmental issues, and will contribute to the realization of a low-carbon society.

(*1)    In an effort to further introduce and expand the use of new energy sources, the RPS law (the Special Measures Law Concerning the Use of New Energy by Electric Utilities) obliges electric utilities to source no less than a specific fixed quantity of their power from new energy sources.
