100% Renewable Energy Microgrid using a Private Transmission Line

News from the ever-interesting Japan for Sustainability site:

The Japanese New Energy and Industrial Technology Development Organization (NEDO), an independent administrative agency, has begun a test to demonstrate a new decentralized energy supply system using a private transmission line (5 kilometres in length) in Hachinohe City, Aomori Prefecture. A total of 710 kilowatts of electricity generated by gas engines, photovoltaics and wind turbines, is being supplied to city hall, elementary and junior high schools and other buildings in the city.

The NEDO web site has more information on this project, including a diagram.
