("Mizuho Corporate Bank") today announced that the companies have been selected as contractors for a world-leading smart grid demonstration project on Maui Island in Hawaii ("Project"), spearheaded by the New Energy and Industrial Technology Development Organization ("NEDO") as the result of feasibility study which was conducted from May to September this year by Hitachi and other companies. Serving as the project leader, Hitachi will take a leading role and coordinate the entire project.

The Project, a joint undertaking by the U.S. and Japan, is based on the Japan-U.S. Clean Energy Technologies Action Plan, which was agreed to following the Japan-U.S. Heads of State Summit held in November 2009.
