Tokyo, Oct. 26 (Jiji Press)–Electricity demand in the area covered by Tokyo Electric Power Company Holdings Inc. <9501> may approach maximum supply this winter, a government estimate found Tuesday.


The electricity reserve rate, or excess capacity over demand, is projected to come close to falling below the 3 pct threshold for maintaining a stable power supply in the TEPCO service area if Japan experiences a once-in-a-decade cold wave.


The power supply and demand outlook for this winter was released at a meeting of experts in the industry ministry.


The estimate found that, while all regions in Japan can maintain a reserve rate of at least 3 pct, the area served by TEPCO will likely see the reserve rate fall to 3.2 pct in January and 3.1 pct in February.


The rate is estimated to drop below 4 pct in areas covered by Chubu Electric Power Co. <9502>, Hokuriku Electric Power Co. <9505>, Kansai Electric Power Co. <9503>, Chugoku Electric Power Co. <9504>, Shikoku Electric Power Co. <9507> and Kyushu Electric Power Co. <9508> as well.


The ministry described the figures as the toughest estimates in the past decade.


The ministry plans to boost efforts to monitor power supply and demand to prepare for any unplanned suspensions of power plants. In the event that demand is close to reaching the supply capacities, the ministry will call on people to use electricity efficiently.


The government also decided that all power utilities excluding Okinawa Electric Power Co. <9511> will procure additional generator fuel through public bidding for the first time in order to prepare for unexpected power shortages.


A shortage of liquefied natural gas and other fuels caused a power squeeze early this year.
