Tokyo Electric Power Co. (TEPCO) announced operating revenues in the first
quarter of fiscal year 2005 (from April 1 to June 30, 2005) increased by
2.7% from the year-earlier period to ¥1,181.7 billion (¥1,108 billion on
an unconsolidated basis, down 1.2%).  Ordinary income fell 47.7% to ¥44.3
billion (¥40 billion, down 48.8%).  Net income decreased by 54.6% to
¥24.6 billion (¥24.6 billion, down 50.8%).

Electricity sales in the first quarter decreased by 0.5% from the
year-earlier period to 66.2 billion kWh as electricity demand from the
industrial sector was lower than the year-earlier level, though electricity
sales for residential use increased as heating demand increased thanks to
the temperatures remained lower than the year-earlier levels in March and
April.

Of the total, electricity sales for residential use increased by 2.5% from
the year-earlier period to 20.5 billion kWh.  Low-voltage power decreased
by 2.5% to 2.9 billion kWh.  Specified-scale demand fell 1.7% to 42.8 billion kWh.

Among revenues in the first quarter, electricity industry sales revenues
decreased by 2.3% from the year-earlier period to ¥1,053.2 billion because
of the decrease in electricity sales and the reduction in electricity
charges in October 2004.  Total operating revenues, which also include
sales to other utilities or companies and those at POWEREDCOM, Inc. that
became a TEPCO subsidiary at the end of first half of fiscal year 2004,
increased by 2.7% to ¥1,181.7 billion (¥1,108 billion on an unconsolidated
basis, down 1.2%).  Ordinary revenues rose 2.7% to ¥1,189.7 billion
(¥1,113.2 billion, down 1.1%).

Among electricity industry expenses, though TEPCO has tried to improve the
efficiency further and reduce the cost of overall operations such as
reduction in depreciation expenses by cutting plant and equipment
investment, the fuel cost increased due to the jump in crude oil prices.
On a consolidated basis, costs increased as POWEREDCOM, Inc. became a
subsidiary.
As a result, ordinary expenses increased by 6.6% to ¥1,145.4 billion
(¥1,073.2 billion on an unconsolidated basis, up 2.4%).
