Today, the Tokyo Electric Power Company, Inc. ("TEPCO") and Mitsui & Co., 
Limited ("Mitsui") announce that the Arabian Power Company ("APC"), 
a project company, began commercial operation of a new natural gas advanced

Water Project in Abu Dhabi, UAE on July 21. APC is composed of TEPCO, Mitsui,

power plants with a generation capacity of 850MW and desalination facilities 
with a daily output of 750,000 tons of water. In addition, APC has been 
constructing several new expansion plants with a thermal generation capacity 
of 1,550MW and a desalination capacity of 110,000 tons of water per day. 

The new plant was constructed utilizing Advanced Combined Cycle (ACC) Technology, 
of which TEPCO has extensive operation and maintenance experience. Natural 
gas is supplied by the Abu Dhabi National Oil Company (ADNOC). 

All electricity and desalinated water will be purchased by the Abu Dhabi 
Electricity and Water Company (ADWEC), which is wholly-owned by ADWEA.

The existing and new facilities are operated and maintained by an operating 
company, ITM O&M Company Limited, which is owned 30% by TEPCO and 70% by IPR.

TEPCO trusts that through utilization of its technical expertise and O&M 
know-how, it will continue to develop investment in overseas businesses 
in a proactive manner for further growth.
