  1. ■ Topics on TES from Japan after the 72th EXCO Meeting (Aibling,Germany) Big problem : Japanese Energy Condition ・DestroyedNuclear Power Plant (4 Reactors) by “Earthquake and Tumani”onMarch 11, 2011 We can not to operate NPP after Periodical Inspection because of Social Condition ・Every Nuclear Power Plants in JAPAN sttoped on May 5, 2012 (54 Reactors : total 48.88 million kW)

  2. Transitions in the Electric Power supply by 10 Japanese Utilities nuclear(29% ; 2009)

  3. ■Comparison Electric comsumption situation ( onPeak Load day) of several Building which has TES HVAC System between bifore the Disaster and last year(after the Disaster :We had to save the electric demand)
