APPENDIX
Fortum Espoo Oyj Interim Report January-June 2006



INTERIM REPORT JANUARY 1 - JUNE 30, 2006

(Stated according to IFRS)


Review of the Group's business operations


The Group's electricity sales increased by 4 % to 1,5 TWh during the first six
months of the year compared to the same period last year .

Electricity distribution increased by 6 % to 1,4TWh. The increase in
distribution was mainly due to cold weather during winter period and due to
organic growth in the operating areas.

The Group's district heat sales increased by 8 % to 1,6 TWh. The heating demand
in the first part of the year was higher compared to previous year in the
operating areas.

Electricity generation at the company's production plants totalled 0,6 TWh (0,6
TWh). The Espoo power plant generated 0,4 TWh of electricity and the Joensuu
power plant 0,2 TWh. The Group's own electricity generation accounted for 37 %
(40 %) of all electricity acquired. The Group's own power plants generated
district heat 1,7 TWh (1,6 TWh). The fuels used by the power plants were coal,
natural gas, wood and peat.


Revenue increased and profit decreased


Fortum Espoo's revenue increased by 12% to EUR 140 million (EUR 125
million). Revenue growth in electricity and generation units was due to
higher market price of electricity.

The Group's operating profit decreased by 25 % to EUR 30 million (EUR 40
million). Profit before taxes was EUR 31 million (EUR 41 million). Earnings per
share were EUR 1,52 (EUR 1,96).

The profit declined because of the changes in electricity market price effecting
to the value of derivative hedging contract position. However Group's operating
profit increased compared to profit year before when the change of valuation in
hedging portfolio is excluded.


Segment reviews


Revenue from electricity segment increased by 26 % to EUR 60 million (EUR 48
million). The increase was mainly caused by a higher price level in commission-
based sales.

Operating profit from the electricity segment was EUR 18 million (EUR 27
million). The decrease in the operating profit was due to changes in market
price, which affected the profit through an open position in derivative
contracts. According to the IFRS regulations, any changes in the market values
of
electricity derivatives are to be recognised in the income statement, because
the
company does not apply derivatives-related hedge accounting in conformance with
the IAS 39.

Revenue from the network segment was 5 % lower than previous year totalling EUR
26 million (EUR 28 million). Prices were lowered both in July and December
2005,
which decreased this year's revenue . On the other hand, distribution volumes
have increased due to organic growth and cold weather conditions in the
operating
areas year 2006. Increased distribution volumes compensated some of the decrease
in revenue caused by lower prices. The segment's operating profit totalled EUR
11 million (EUR 12 million).

Revenue from the district heating segment increased by 10 % from the previous
year to EUR 56 million (EUR 51 million). The high heating demand in January -
March increased revenue. However, due to higher fuel costs, the operating profit
of the district heating segment was lower than previous year totalling EUR 9
million (EUR 10 million).

Operating profit of the generation segment was EUR - 7 million (EUR - 8
million).
The valuation of electricity derivatives hedging portfolio turned the result
negative.


Investments mainly network investments

period. Approx. EUR 7 million was invested in construction of electrical power
networks and approx. EUR 5 million in construction of district heating networks.

The company's physical production of electricity along with its electricity
sales and trading activities exposes it to electricity
price risk. The company actively uses electricity forward contracts and
electricity options to hedge the electricity price risk. The company
systematically monitors the risk position arising from electricity trading and
the risk position in derivatives. Limits have been set relating to electricity
trading and they are monitored systematically.

Foreign exchange risk arises mainly from cash flows denominated in USD. The
foreign exchange position consists of commercial commitments and expected cash
flows from highly probable transactions related to the company business, and
of related hedging in respective currencies.
