Tokyo Electric Power Co. (TEPCO) announced that its operating revenues in
the first quarter of fiscal year 2006 (from April 1 to June 30, 2006)
increased by 3.3% from the year earlier period to ¥1,220.2 billion
(¥1,160.3 billion on an unconsolidated basis, up 4.7%). Ordinary income
rose 83.9% to ¥81.5 billion (¥65.7 billion, up 64.2%). Net income increased
by 95.3% to ¥48.0 billion (¥38.7 billion, up 57.0%).

Electricity sales in the first quarter increased by 1.9% from the year
earlier period to 67.4 billion kWh as the electricity demand for residential
use increased in proportion to the increase in the number of contracts,
in addition to the bulk electricity demand for industrial sector.
Of the total, electricity sales for residential use rose 2.9% to 21.1
billion kWh. Sales for low voltage power decreased by 2.2% to 2.8 billion
kWh. Specified-scale demand increased 1.7% to 43.5 billion kWh.

Among the revenues in the first quarter, electric power operating revenues
increased by 3.7% from the year earlier period to ¥1,092.2 billion because
of the increased electricity sales in spite of some adverse effect resulting
from the rate reduction introduced in April 2006. As a result, total
operating revenues, including the revenues from inter-company power sales
and the electricity sales to other companies, increased by 3.3% to ¥1,220.2
billion (¥1,160.3 billion on an unconsolidated basis, up 4.7%). Ordinary
revenues increased by 3.9% to ¥1,236.3 billion (¥1,168.8 billion, up 5.0%).

Among electric power operating expenses, though TEPCO made efforts to 
further improve efficiency of overall operations in the electricity 
power business, including reduction in depreciation expenses through 
restrictive capital investments, ordinary expenses increased by 0.8% 
from the year earlier period to ¥1,154.7 billion (¥1,103 billion, up 2.8%)
because of a drastic increase in fuel costs due to a sharp rise in crude
oil prices.
