Tokyo Electric Power Co. (TEPCO) announced that operating revenues for the 
first three quarters of Fiscal year 2006 (from April 1 to December 31, 2006) 
increased 1.7% from the same period of the previous year to ¥3,879.9 billion 
(up 3.1% to ¥3,685.0 billion on a non-consolidated basis).  Ordinary income 
increased 43.1% to ¥416.5 billion (up 29.8% to ¥362.0 billion on a 
non-consolidated basis).  Net income increased 41.9% to ¥254.8 billion 
(up 22.1% to ¥224.3 billion on a non-consolidated basis).

Electricity sales in the first three quarter increased 0.6% from the same 
term of previous year to 213.7 billion kWh, due to the increase in large 
industrial power sector, although demand for residential use decreased as 
the temperatures were higher than the previous year levels in November 
and December.
Of the total, electricity sales for residential use decreased by 0.1% from 
the same term of the previous year to 66.4 billion kWh.  Sales for low-voltage 
power in the non-liberalized sector decreased by 4.7% to 9.4 billion kWh.
Electricity sales to specific-scale demand increased 1.3% to 137.9 billion kWh.

On the revenue side, the electricity revenues increased 2.0% from the same 
term of the previous year to 3,458.8 billion yen due to the increase in 
electricity sales despite the influence from the reduction of the electricity 
tariff since last April.  The operating revenues increased 1.7% from the 
same term of the previous year to 3,879.9 billion yen (non-consolidated 
figure increased 3.1% from the same term of the previous year to 3,685.0 
billion yen) after adding inter-company power sales and sales of power to 
other companies.  The ordinary revenues increased 2.2% from the same term 
of the previous year to 3,934.8 billion yen (non-consolidated figure increased 
3.2% from the same term of the previous year to 3,716.9 billion yen).

Ordinary expenses decreased 1.1% from the same term of the previous year 
to 3,518.2 billion yen (non-consolidated figure increased 1.0% from the 
same term of the previous year to 3,354.8 billion yen) due to the efforts 
to improve efficiency in overall business such as the decrease in depreciation 
cost caused by the restraint of capital expenditure, and the effect from 
merger of POWEREDCOM, Inc. with KDDI (on consolidated basis) on last January, 
despite the increase in nuclear power back-end expenses, fuel cost and 
electricity purchase expenses caused from the rise of crude oil prices.
