Non-GAAP financial measures: This report contains certain non-GAAP financial measures. Management believes that the non-GAAP financial measures used by E.ON, when considered in conjunction with (but not in lieu of) other measures that are computed in U.S. GAAP, enhance an understanding of E.ON’s results of operations. A number of these non-GAAP financial measures are also commonly used by securities analysts, credit rating agencies, and investors to evaluate and compare the periodic and future operating performance and value of E.ON and other companies with which E.ON competes. Additional information with respect to each of the non-GAAP financial measures used in this report is included together with the reconciliations described below.

E.ON prepares its financial statements in accordance with generally accepted accounting principles in the United States (U.S. GAAP). As noted above, this report contains certain consolidated financial measures (Group adjusted EBIT, adjusted EBITDA, net financial position, net interest expense, and free cash flow) that are not calculated in accordance with U.S. GAAP and are therefore considered “non-GAAP financial measures” within the meaning of the U.S. federal securities laws. In accordance with applicable rules and regulations, E.ON has presented in this report a reconciliation of each non-GAAP financial measure to the most directly comparable U.S. GAAP measure for historical measures and an equivalent U.S. GAAP target for forward-looking measures. The footnotes presented with the relevant historical non-GAAP financial measures indicate the page of this report on which the relevant reconciliation appears. The non-GAAP financial measures used in this report should not be considered in isolation as a measure of E.ON’s profitability or liquidity and should be considered in addition to, rather than as a substitute for, net income, cash provided by operating activities, and the other income or cash flow data prepared in accordance with U.S. GAAP presented in this report and the relevant reconciliations. The non-GAAP financial measures used by E.ON may differ from, and not be comparable to, similarly titled measures used by other companies.

Interim Report II/2005

Dear Shareholders,

In the first half of 2005 the E.ON Group continued its positive earnings development. We increased adjusted EBIT by 7 percent year-on-year to €4.3 billion. At roughly €3 billion, net income (after taxes and minority interests) was also 7 percent above the high prior-year figure.

We expect net income for the entire year to considerably surpass last year’s figure, thanks in particular to the book gains totaling roughly €3 billion we expect on the sale of Viterra and Ruhrgas Industries. We will record a gain of approximately €2.4 billion on the sale of Viterra to Deutsche Annington. We sold Ruhrgas Industries to CVC Capital Partners, a European private equity firm, and expect to record a gain of approximately €600 million on the sale. With these disposals, we have almost completed E.ON’s transformation into a pure-play energy company.

In the second quarter we also took important steps to expand our market positions in our core energy business. We reached an agreement to acquire NRE Energie, a Dutch power and gas company. The acquisition gives us our first end customers in the Netherlands and complements our existing power production and gas trading operations there. In addition, we completed the acquisition of Distrigaz Nord, a Romanian gas distribution company, which further enlarges our market position in Central and Eastern Europe, a region experiencing dynamic economic growth. Our acquisition of Holford Gas Storage in the United Kingdom in July will set in motion the construction of one of the country’s largest natural gas storage facilities and in the future give us greater flexibility in gas procurement.

These growth initiatives represent a continuation of the course we have been pursuing in recent years. In the last two years we have implemented growth initiatives amounting to more than €7 billion. This figure includes small and medium-sized acquisitions in our European target markets and investments in power and gas transmission, distribution, and production assets.

An important energy policy development for us is Germany’s revised New Energy Law, which took effect on July 13. The law makes an important contribution towards the establishment of a stable investment environment for our grid operations. It is now essential that the regulatory agency moves forward as quickly as possible to develop and implement a system that rewards network operators for increases in productivity. We are actively involved in this discussion and have proposed a model that we believe achieves a balance between promoting cost reductions and ensuring supply security. By drawing on our experience in other regulated markets as we participate in this discussion we are making an important contribution towards the creation of a sensible incentive system for the regulation of Germany’s network infrastructure.

This demonstrates that we are playing a constructive role in shaping the regulatory landscape in which we operate so that we can supply our customers with power and gas reliably and efficiently. Ultimately, all of these efforts will create a reliable investment environment in which we can achieve further growth in our core business. We will continue to focus our energy and the Group’s capabilities on profitably expanding our market positions in and outside Germany.

Sincerely yours,

Dr. Wulf H. Bernotat

Interim Report II/2005

Results of Operations

Energy Price Developments

The gas and power markets E.ON operates in are heavily influenced by the development of oil and coal prices.The introduction of the European Emissions Trading Scheme has meant that CO2 certificate prices play an increasingly important role in European energy markets.

Due to tight supply fundamentals, the price of Brent crude oil climbed to $59 per barrel by the end of June 2005, an $18 per barrel, or 45 percent, increase from the price at the start of the year and a $26 per barrel, or 80 percent, increase from the average price in the first half of 2004. Natural gas prices in Europe and the United States followed this trend.

CO2 certificate prices tripled in the second quarter to nearly €26 per metric ton from the low prices in January. Rising gas and oil prices contributed to this development, since higher gas prices served to increase the share of electricity generated from coal, resulting in greater demand for certificates.

Coal prices remained high in the first half of 2005 and traded as high as $72 per metric ton for year-ahead delivery, which is slightly above the prices quoted in the first weeks of 2005 and $7 per metric ton, or 11 percent, above the average price for the first half of 2004. Since April, however, coal prices have declined due to lower freight rates.

Wholesale power prices increased, tracking fuel and CO2 certificate prices. In the U.K. and U.S., power prices were mainly driven by natural gas prices, in Germany mainly by coal and CO2 certificate prices. Prices at Nordpool, Scandinavia’s power exchange, appear to be increasingly influenced by CO2 certificate prices and by prices on the EEX, the German power exchange.

Power and Gas Sales Volumes Higher

We sold 3 percent more electricity in the first half of 2005 than in the same period last year, due largely to increased sales volumes in Germany resulting from the national burden-sharing agreement for renewable-source electricity.The inclusion of Gorna and Varna, newly consolidated regional electric distribution companies in Bulgaria, also contributed to the improvement. Higher sales volumes outside Germany at our Pan-European Gas market unit were the main factor in the 6 percent increase in gas sales.

Corporate Center		-658		-325		—
Sales		28,408		24,588		+16

Sales up 16 Percent

The increase in sales resulted in particular from the passthrough of costs under Germany’s Renewable Energy Law, higher sales volumes, changes in the scope of consolidation, and price developments in the power and gas businesses.

Adjusted EBIT up 7 Percent

In the first half of 2005 all of our market units, with the exception of Pan-European Gas, continued their positive earnings development. Adjusted EBIT rose by 7 percent year-on-year to €4.3 billion. We benefited in particular from higher wholesale prices for electricity. Also contributing to our improved adjusted EBIT performance were increased hydroelectric generation at Nordic and rate increases at U.S. Midwest.

By contrast, Pan-European Gas’s results were negatively impacted by continued higher heating oil prices. Natural gas prices are linked to heating oil prices. As a result, natural gas procurement costs have risen substantially. Because gas prices respond to changes in heating oil prices more rapidly on the procurement side than on the sales side, there was a significant adverse affect on Pan-European Gas’s adjusted EBIT.

Net income Surpasses High Prior-Year Level Adjusted interest income (net) declined to –€536 million, primarily due to the absence of last year’s one-off gain of approximately €270 million resulting from amendments to Germany’s Ordinance on Advance Payments for the Establishment of Federal Facilities for Safe Custody and Final Storage for Radioactive Wastes (Endlager-Vorausleistungsverordnung). Among the positive factors was a decline in net debt.

Net book gains in the first half of 2005 were significantly below last year’s figure. In the period under review they resulted from the sale of securities. The prior-year number includes book gains on the sale of equity interests in EWE and VNG (€317 million) and on the sale of securities (€124 million) and the sale of more Degussa stock (€63 million).

Other nonoperating earnings primarily reflect positive effects from the marking to market of energy derivatives at the U.K. market unit. We use derivatives to protect our operations from the effects of price fluctuations. Since March 2005 the market value of these derivatives has increased by about €680 million, in large part due to sharply higher power and gas prices. The costs relating to the severe storm in Sweden at the beginning of the year reduced other nonoperating earnings by about €140 million. The prior-year figure mainly includes positive effects from the marking to market of energy derivatives.

Our continuing operations recorded a tax expense of €1,514 million in the first half of 2005. The increase results primarily from improved operating results and a lower share of tax-free earnings.

Income/Loss (–) from discontinued operations, net, mainly reflects the results of Viterra and Ruhrgas Industries, for which we have concluded sales agreements. Under U.S. GAAP, the results of disposal groups are reported separately in the Consolidated Statements of Income (see commentary on pages 24-25).

Net income (after income taxes and minority interests) surpassed the high prior-year level. Earnings per share of €4.59 were likewise up year-on-year, increasing 7 percent from last year’s figure.

Investments Significantly below Prior-Year Figure In the period under review the E.ON Group invested €1.8 billion, a 36 percent decline year-on-year. We invested €1.1 billion (prior year: €1 billion) in intangible assets and property, plant, and equipment. Investments in financial assets totaled €769 million versus €1.8 billion in the prior year. The decline is in particular attributable to the Corporate Center. The high prior-year figure mainly reflects payments for bonds repurchased in conjunction with the acquisition of Midlands Electricity.

In the first half of 2005 the Central Europe market unit invested €728 million, roughly 15 percent less than in the prior-year figure. Investments in intangible assets and property, plant, and equipment totaled €527 million (prior year: €432 million). Investments in financial assets totaled €201 million (prior year: €425 million). The greater part of capital expenditures for property, plant, and equipment went towards power generation and distribution assets.

Pan-European Gas invested approximately €224 million in the first half of 2005. Its largest single investments were the acquisition of a majority interest in Distrigaz Nord, a Romanian gas utility, and the increase of its shareholding in Interconnector Limited of the U.K. from 10 percent to 17.4 percent. This market unit also invested in infrastructure upgrade projects. Twenty-seven percent of investments went towards intangible assets and property, plant, and equipment, while 73 percent went towards the acquisition of shareholdings.

Investments at U.K. for the first half of 2005 were €412 million against €258 million for the prior year. Investments in financial assets were €220 million higher than in the prior year due to investments in the Enfield CCGT asset and the acquisition of Economy Power’s retail small and medium sized enterprise customers. Investments in intangible assets and property, plant, and equipment were €66 million lower than in the prior year, largely due to higher expenditure in 2004 on Scroby Sands offshore wind farm. Capital expenditure for additions to property, plant, and equipment was directed primarily at renewable generation, conventional power stations, and the regulated distribution business.

Nordic invested €150 million in intangible assets and property, plant, and equipment during the first half of 2005 in order to maintain its existing production plants and to upgrade and enhance its distribution network. This compares with €171 million during the corresponding period in 2004. Repair work and reconstruction necessitated by the severe storm in January have postponed other planned investments. The higher total investments during the first half of 2004 included the acquisition of the remaining shares in Graninge (€307 million).

Investments at U.S. Midwest were lower in 2005 due to lower construction spending on utility plant.

Financial Condition

Management’s analysis of E.ON’s financial condition uses, among other financial measures, cash provided by operating activities, free cash flow, and net financial position. Free cash flow is defined as cash provided by operating activities less investments in intangible assets and property, plant, and equipment. We use free cash flow primarily to make growth-creating investments, pay out cash dividends, repay debts, and make short-term financial investments. Net financial position equals the difference between our total financial assets and total financial liabilities. Management believes that these financial measures enhance the understanding of the E.ON Group’s financial condition and, in particular, its liquidity.

The E.ON Group’s cash provided by operating activities in the first half of 2005 was slightly above the prior-year level.

Interim Report II/2005

Cash provided by operating activities at Central Europe increased year-on-year because the gross margin was higher and payments for nuclear fuel reprocessing were lower than in the prior-year period. In addition, tax payments were higher in the prior year. By contrast, in 2005 there was a higher increase in receivables which we expect to be reversed in the second half of the year.

In the first half of 2005 Pan-European Gas recorded a marked increase in cash provided by operating activities. The contributing factors were a temperature-driven increase in withdrawals from gas storage facilities and lower intercompany tax offsets compared with the prior-year period.

Cash provided by operating activities at U.K. declined significantly year-on-year because pension fund payments of €629 million in the second quarter of 2005 exceeded the prior-year figure. These one-off payments cover a portion of the actuarial deficit of U.K.’s pension plans. In addition, there was an increase in the working capital requirements in the first half of 2005 which we expect to be reversed in the third and fourth quarter.

The significant decline in Nordic’s cash provided by operating activities resulted from a number of nonrecurring items. These include increased cash outflows stemming from the severe storm in January and higher tax payments. Improvements at Nordic’s gas business and increased power production at its hydroelectric facilities had a positive influence on cash provided by operating activities.

Cash provided by operating activities at U.S. Midwest was higher year-on-year due to the absence of certain nonrecurring charges—including pension plan contributions and the phaseout of an asset-backed securities program—that negatively affected the prior-year figure.

The Corporate Center’s cash provided by operating activities was higher year-on-year due to positive effects from the unwinding of currency swaps and from higher tax refunds.

In general, surplus cash provided by operating activities at Central Europe, U.K., and U.S. Midwest is lower in the first quarter of the year (despite the high sales volume typical of this season) due to the nature of their billing cycles, which in the first quarter are characterized by an increase in receivables combined with cash outflows for goods and services. During the remainder of the year, particularly in the second and the third quarters, there is typically a corresponding reduction in working capital, resulting in significant surplus cash provided by operating activities, although sales volumes (with the exception of U.S. Midwest) are actually lower. The fourth quarter is characterized by an increase in working capital. At Pan-European Gas, by contrast, cash provided by operating activities is recorded principally in the first quarter, whereas there are cash outflows for intake at gas storage facilities in the second and third quarters and for gas tax prepayments in the fourth quarter. A major portion of the market units’ capital expenditures for intangible assets and property, plant, and equipment is paid in the fourth quarter.

With the stable level of investments in intangible assets and property, plant, and equipment, free cash flow was slightly above the prior-year number.

This was caused mainly by strong cash provided by operating activities and by the fact that for the first time Viterra is recorded under discontinued operations. Our net financial position was adversely affected by financial outlays for investments in property, plant, and equipment and in shareholdings. The dividend payout and the related tax payment also led to cash outflows.

Net interest expense declined by a substantial €189 million year-on-year, mainly reflecting lower net debt in the first half of 2005. In addition, the prior-year figure includes a nonrecurring adverse effect relating to the repurchase of Powergen bonds. A further factor in the current-year period was the higher share of financial liabilities with a variable interest rate. Net interest expense only includes the interest income of those items that are also part of the net financial position.

On March 14, 2005, Standard & Poor’s confirmed its AA– long-term rating for E.ON bonds and lowered its outlook from stable to negative. Since April 30, 2004, Moody’s long-term rating for E.ON bonds is Aa3 with a stable outlook. Commercial paper issued by E.ON has a short-term rating of A-1+ and P-1 by Standard & Poor’s and Moody’s, respectively. E.ON has committed itself to maintaining at least a strong single-A rating.

Employees

On June 30, 2005, the E.ON Group had 78,006 employees worldwide in its core energy business, as well as 1,816 apprentices and 241 board members and managing directors. Our workforce increased by 17,410 employees, or 29 percent, since December 31, 2004. At the end of the first half of 2005, 43,809 employees, or 56 percent of all staff, were working outside Germany, about 11 percentage points more than at year end 2004 (45 percent). This development is mainly attributable to the addition of Distrigaz Nord (9,300 employees), a Romanian gas distribution company, at the Pan-European Gas market unit.

The number of Central Europe’s employees increased by 15 percent from the figure for year end 2004. This resulted from the addition of Gorna Oryahovitza and Varna, regional electric distribution companies in Bulgaria (a total of about 3,700 employees), the IT service provider E.ON IS (formerly is:energy, about 1,300 employees), and DDGáz and Kögáz, Hungarian gas distribution companies (a total of about 900 employees).

At the end of the first half of 2005, the U.K. market unit had 12,363 employees. This roughly 19 percent rise from year end 2004 is attributable to the integration of staff formerly employed by an external service provider.

During the reporting period, wages and salaries including social security contributions totaled €2.2 billion, compared with €2 billion a year ago.

Interim Report II/2005

Risk Situation

In the normal course of business, we are subject to a number of risks that are inseparably linked to the operation of our businesses.

Technologically complex facilities are involved in the production and distribution of energy. Operational failures or extended production stoppages of facilities or components of facilities could adversely impact our earnings situation. We address these risks through ongoing employee training and qualification programs and regular facility and system maintenance.

During the normal course of business, E.ON is exposed to interest rate, currency, commodity price, and counterparty risks which we address through the targeted use of financial instruments.

Our market units operate in an international market environment characterized by general risks related to the business cycle and by more intense competition. We use a comprehensive sales monitoring system and derivative financial instruments to minimize the price and sales risks of liberalized markets.

The political, legal, and regulatory environment in which the E.ON Group does business is a source of additional external risks. Our goal is to play an active and informed role in shaping our business environment. We pursue this goal by engaging in a systematic and constructive dialog with political leaders and representatives of government agencies.

The operational and strategic management of the E.ON Group relies heavily on complex information technology. Our IT systems are maintained and optimized by qualified E.ON Group experts, outside experts, and certain technological security measures.

In the period under review the E.ON Group’s risk situation did not change substantially from year end 2004.

Outlook

For 2005 we expect the E.ON Group’s adjusted EBIT to be slightly above the record number we posted in 2004. Thanks to the successful divestment of Viterra and Ruhrgas Industries, we expect net income for 2005 to substantially surpass the prior-year figure.

The earnings forecast by market unit is as follows:

For 2005 we expect the adjusted EBIT of the Central Europe market unit to be above the prior-year number. The main drivers will be the passthrough of higher wholesale electricity prices to end customers, the implementation of groupwide optimization programs, and the realization of regional synergies.

We now expect Pan-European Gas’s adjusted EBIT to be slightly below the figure for 2004 due to sharply higher heating oil prices. In addition, we anticipate that our acquisition of a majority ownership interest in the gas business of Hungary’s Mol will be delayed.

For the U.K. market unit, we expect adjusted EBIT to be slightly above prior year’s level. From today’s perspective, the growth rate seen in the first half of 2005 will decrease, mainly due to integration costs in the non-regulated business.

We anticipate that Nordic’s adjusted EBIT for 2005 will be on par with the figure posted in 2004. For the remainder of the year the favorable development of Nordic’s business year to date will be largely offset by lower retail earnings as a result of the January storm and by planned costs for rebranding Sydkraft to E.ON Sverige.

We expect U.S. Midwest’s 2005 adjusted EBIT to be slightly ahead of the 2004 figure in local currency. From today’s perspective, the positive effects of higher gas and electric rates will be partly offset by higher coal prices in the non-regulated business.

Electricity prices on European’s energy exchanges rose sharply during the first half of 2005. EEX prices for year-ahead baseload power topped €43 per MWh for the first time, a 25 percent increase from the prices quoted in January of this year. Price levels reflect continued high coal prices and the substantial increase in prices for CO2 certificates.

Depending on their analysis of the market and their willingness to accept risk, larger industrial customers tended to be reluctant to enter into new supply agreements. Electricity prices for residential customers were unchanged in the second quarter.

Central Europe sold approximately 8.4 billion kWh more electricity than in the prior-year period, mainly due to the sale of larger volumes of electricity the company was required to purchase under the Renewable Energy Law. Another factor was the inclusion of Gorna and Varna, Bulgarian regional electric distribution companies that became consolidated E.ON subsidiaries in the period under review.

Central Europe met about 48 percent of its power requirements with electricity from its own generation assets, compared with 53 percent in the year-earlier period. Central Europe’s generation business can capitalize on the advantages of a flexible energy resource portfolio. Compared with the prior year, Central Europe procured around 11 billion kWh more electricity from jointly owned power stations and outside sources. This increase is principally attributable to the purchase of larger volumes of wind power subsidized under the Renewable Energy Law as well as to the inclusion of the Bulgarian regional electric distribution companies.

Despite the inclusion of Hungary’s Kögáz and DDGáz and two gas utilities at E.ON Bayern, all of which became consolidated E.ON companies in the period under review, gas sales at Central Europe’s regional utilities were unchanged from the prior-year figure. The factors include temperature-driven declines in sales volume and keener competition in the sales partner and the industrial and commercial segments.

Central Europe grew sales by 15 percent relative to the prior-year period, mainly due to the passthrough of costs for electricity subsidized under the Renewable Energy Law, higher electricity and gas prices in Germany, and the consolidation effects mentioned above.

Adjusted EBIT rose €178 million year-on-year, with Central Europe’s business units developing as follows:

Central Europe West Power grew adjusted EBIT by €212 million, chiefly due to improved gross margins. The key factor was the passthrough to end customers of the fuel-driven increase in wholesale prices. Adverse affects include higher costs for conventional fuel and for electricity purchased from jointly owned power stations and outside sources.

Adjusted EBIT at Central Europe West Gas was €12 million below the prior-year level. Lower sales volumes and higher procurement costs could not be counteracted by the consolidation effects at E.ON Bayern or by higher sales prices.

Central Europe East’s adjusted EBIT increase of €14 million is attributable to the inclusion of Varna and Gorna, which became consolidated E.ON companies on March 1, 2005, and to the sale of minority stakes in the Czech Republic.

Adjusted EBIT recorded under Other/Consolidation declined by €36 million year-on-year, mainly due to lower equity earnings and the divestment of shareholdings in the prior year.

In the first half of 2005 Germany’s consumption of primary energy fell by 1 percent, while its consumption of natural gas rose by 1 percent relative to the same period last year. A temperature-drive increase in demand in the first quarter was followed by a further slight increase in the second quarter. Second-quarter temperatures in E.ON Ruhrgas’s sales territory were on par with the prior-year figure and about 0.4°C below the historical average.

E.ON Ruhrgas AG sold 363.1 billion kWh of gas in the first half of 2005, about 8 percent more than in the prior-year period. Second-quarter sales volumes rose by 10 percent year-on-year to 137.5 billion kWh.

1 Gas sales of E.ON Ruhrgas AG.

The volume growth resulted mainly from higher sales volumes outside Germany, which increased by over 70 percent year-on-year. Outside Germany, Pan-European Gas’s most import sales markets are the U.K. and Switzerland. Along with gas deliveries to E.ON UK, which began in October 2004, deliveries to new customers in France, Denmark, and Italy also contributed to the positive development of this market unit’s international business. In addition, a two-year supply contract was concluded with a new industrial customer in Denmark in the second quarter of 2005. Furthermore, a supply agreement was reached with Thüga Italia for the 2005/ 2006 delivery period. In Germany, E.ON Ruhrgas AG sold more gas in the second quarter, primarily to publicly owned power stations. Sales volumes to regional gas companies and municipal utilities were stable, while those to industrial customers declined slightly.

As in the previous year, regional gas companies constituted E.ON Ruhrgas AG’s largest customer segment, accounting for 49 percent of total gas sales (prior year: 53 percent). Twenty-four percent (prior year: 25 percent) of total sales went to municipal utilities. Deliveries to industrial customers accounted for 9 percent (prior year: 11 percent) of total sales. Sales outside Germany increased from 11 percent of total sales in the first half of 2004 to 18 percent in the period under review.

Sales at Pan-European Gas increased to €8.9 billion, while adjusted EBIT declined by 8 percent, in the first six months of 2005.

The Up-/Midstream business unit grew sales by 38 percent year-on-year to €6.4 billion. This positive sales performance results mainly from higher sales volumes in the midstream business in conjunction with higher average sales prices. The upstream business also benefited from higher sales prices and increased production compared with the prior-year period. In 2004 Scoter did not begin production until March, whereas in 2005 Scoter produced throughout the entire period under review.

Sales were higher at the Downstream Shareholdings business unit primarily due to consolidation effects at Thüga Italia. In late June 2005 E.ON Ruhrgas acquired a majority ownership interest in Distrigaz Nord, a Romanian gas distribution company. Distrigaz Nord became a consolidated E.ON company on June 30, 2005.

The main factor behind the decline in Pan-European Gas’s adjusted EBIT was the midstream business, which was adversely affected by continued higher heating oil prices. Natural gas prices are linked to heating oil prices. As a result, natural gas procurement costs have risen substantially. Because gas prices respond to changes in heating oil prices more rapidly on the procurement side than on the sales side, there was a significant adverse affect on adjusted EBIT.

Interim Report II/2005

Overall, the Up-/Midstream business unit’s adjusted EBIT fell by 21 percent. The positive development of the upstream business, where higher oil and gas prices contributed to an improved adjusted EBIT performance, counteracted only to a limited degree the adverse effects in the midstream business.

The Downstream business unit grew adjusted EBIT by 19 percent year-on-year to €347 million. This is principally attributable to higher equity earnings at E.ON Ruhrgas International and Thüga.

Gas prices at the National Balancing Point rose significantly in the first half of 2005, driven by the rise in forward oil prices and continued security of supply concerns for the winter. Across the six months, the price of the 2006 calendar year product rose from 32 pence per therm to 56 pence per therm. This represents an increase of 75 percent since the start of the year and a 93 percent increase over the last 12 months.

Power prices in the U.K. continued to be driven by rising gas prices and increasingly by carbon prices. In the first six months of 2005, winter 2005/2006 baseload contracts increased from £33 per MWh to close at above £59 per MWh. This represents an increase of 79 percent since the start of the year and an increase of 90 percent over the last 12 months.

In response to increases in wholesale energy prices, the U.K. market unit has increased its consumer retail prices for electricity by 7.2 percent and for gas by 11.9 percent with effect from August 31, 2005. Other leading suppliers have indicated that increases in retail prices are likely due to soaring wholesale prices and higher energy efficiency and environmental costs.

The decrease in power and gas sales volumes is in the industrial and commercial market, where the focus has been on securing margin in volatile market conditions.

E.ON UK’s attributable generation portfolio was 8,807 MW at June 30, 2005, an increase of 842 MW from the figure for March 31, 2005, due to the recommissioning of Killingholme Module 2 (450 MW) in April and the purchase of the Enfield CCGT generating asset (392 MW) in April.

E.ON UK increased its sales in the first half of 2005 compared with the prior year as a result of rising retail prices to offset the increase in wholesale energy costs.

Adjusted EBIT at the regulated business was up €8 million due to a full six-month contribution from Midlands Electricity which was acquired on January 16, 2004.

In the non-regulated business, adjusted EBIT increased by €113 million, largely due to special items. These included benefits from the integration of customer services activities relating to former TXU customers that were previously outsourced to an external service provider. In addition, E.ON UK received payments from the TXU administrator for outstanding renewables obligation charges from 2002/2003 and benefited from a favorable settlement on outstanding TXU gas imbalance charges. Furthermore E.ON UK benefited from higher wholesale prices as well as further operational improvements.

The €28 million decrease in adjusted EBIT recorded under Other/Consolidation is mainly due to no deferred warranty income from previous asset sales and lower earnings from the international assets following divestment of the interests in the 1,220 MW Paiton plant in 2004.

During the first six months of the year, average electricity spot prices were slightly lower than in the first half of 2004. Hydropower production has been high, particularly during the spring. This was based on a surplus in the hydrological balance of +15 TWh above long-term average at the beginning of the year. Demand was dampened by above-normal temperatures in January and February and then positively affected by colder weather in March. Spot prices declined

Interim Report II/2005

again at the end of May, when energy-intensive Finnish paper mills were closed due to an industry-wide lockout.

Forward prices for wholesale electricity increased substantially during the first half of this year reflecting rising prices for CO2 emission rights and for oil and coal. In compliance with a decision by the Swedish government, Barsebäck 2, a 600 MW nuclear power plant, was permanently withdrawn on May 31, 2005.

Competition has remained keen on the Nordic retail markets. In the wake of the January storm, in Sweden Sydkraft has focused on restoring public and customer confidence. Recent opinion polls indicate that these measures have been effective. Preparations for rebranding Sydkraft to E.ON Sverige are in progress; the name change will take place in the fall.

After the January storm, Sydkraft estimates that the costs for rebuilding its distribution grid and compensating customers will be approximately €140 million.The direct and indirect effects were significant and affected much of our operations in Sweden.These effects are extraordinary in nature and will not affect adjusted EBIT.

Nordic sold 0.5 billion kWh less electricity compared with the same period in 2004.The decrease resulted from lower sales to residential and commercial customers, primarily as a result of the January storm. Nordic sold 94 percent of its power in Sweden and 6 percent in Finland.

Nordic covered approximately 70 percent of its electricity sales with power from its own generation assets. Generation increased by 0.6 billion kWh relative to the prior-year period. Higher reservoir levels at the start of the year along with higher inflow during the period under review resulted in higher hydropower generation. Nuclear power production declined compared with 2004, which was characterized by very high availability. In 2005, there was one longer and several shorter unplanned outages in Nordic’s reactors. Lower spot electricity prices explain the decline in generation from fossil-fuel and CHP units.

Gas sales increased slightly due to higher sales to industrial customers. Heat sales improved due to lower temperatures in the period under review.

Nordic’s sales of €1,796 million were slightly above the prior-year figure. Lower electricity sales volumes and somewhat lower spot prices were more than compensated by successful hedging activities.

Nordic increased adjusted EBIT by €54 million year-on-year to €447 million. The improvement was primarily a result of increased hydroelectric production and successful hedging activities, which enabled Nordic to secure higher effective sales prices for its production portfolio. Nordic’s adjusted EBIT from its gas operations improved due to a favorable spread between gas oil and fuel oil prices. Nordic’s Finnish business unit reported lower adjusted EBIT, mainly as a result of a decline in earnings from energy trading activities and lower revenues at its retail operations.

Through June 2005, the regulated utility’s retail power sales volumes were relatively flat compared with 2004, while off-system sales volumes were higher compared to 2004 due to higher market prices during the off-peak period. Retail natural gas sales volumes declined due largely to milder winter weather compared with 2004. Off-system sales of natural gas increased due to the sale of volumes not used to serve retail customers.

Ninety-eight percent of U.S. Midwest’s electricity generation was from coal-fired power stations. Gas, oil, hydro, and other energy sources accounted for 2 percent of generation. U.S. Midwest’s generation portfolio decreased by 275 MW from year end 2004 to 9,391 MW due to the sale of the Gregory partnership.

U.S. Midwest’s sales through June 2005 increased 7 percent (in local currency 12 percent) resulting primarily from higher wholesale revenues due to higher prices and the increase in retail electric and gas rates effective July 1, 2004, as approved by the Kentucky Public Service Commission, offset by the U.S. dollar’s deterioration against the euro. Adjusted EBIT increased 7 percent (in local currency 12 percent) mainly driven by higher sales.

Adjusted EBIT at U.S. Midwest’s regulated utility operations improved from 2004 primarily as a result of the increased retail electric and gas rates. In addition, the contribution from off-system sales exceeded the previous year’s figure due to higher prices and volumes in the off-system wholesale electric market offset by costs associated with participation in Midwest Independent Transmission System Operator (MISO), higher depreciation on newly installed assets, and the U.S. dollar’s deterioration against the euro in the first half 2005.

Adjusted EBIT at the non-regulated operations was comparable to 2004.

Notes

Accounting and Valuation Policies

The accounting and valuation policies used to prepare the Interim Financial Statements for the six months ended June 30, 2005, correspond to those used for the Consolidated Financial Statements for the year ended December 31, 2004.

Publication of New Accounting Standards

In March 2005 the FASB issued Interpretation (FIN) 47, Accounting for Conditional Asset Retirement Obligations—An Interpretation of FASB Statement No. 143. FIN 47 clarifies that SFAS 143 also applies to asset retirement obligations even though uncertainty exists about the timing and/or method of settlement. FIN 47 is effective for fiscal years ending after December 15, 2005. E.ON is currently evaluating what effect the adoption of FIN 47 will have on its Consolidated Financial Statements.

Variable Interest Entities

On January 1, 2004, E.ON adopted the revised version of FIN 46 published in December 2003 (FIN 46R).

As of June 30, 2005, E.ON’s variable interest entities (VIEs) consist of two real estate leasing companies, two jointly managed electric generating companies, a company to manage and dispose of real estate, and a company that manages shareholdings.

As of June 30, 2005, E.ON consolidated VIEs with total assets and corresponding liabilities and equity of approximately €1,128 million (including €304 million in assets and liabilities of disposal groups) and earnings of €21 million (including €12 million in income from discontinued operations). Fixed assets and other assets in the amount of €133 million serve as collateral for liabilities relating to financial leases and bank loans. With the exception of two VIEs, there are limits to the recourse of creditors of the consolidated VIEs to the consolidating companies. In the case of these two VIEs, the liabilities total €93 million for the consolidating companies.

In addition, since July 1, 2000, E.ON has had a contractual relationship with a VIE, a leasing company operating in the energy industry, for which we are not the primary beneficiary. This entity has total assets and corresponding liabilities and equity of €120 million and annual earnings of roughly €29 million. E.ON’s maximum exposure to loss relating to this VIE is approximately €15 million. Management considers it unlikely that this loss will be realized.

The financial situation of another special-purpose entity, which has existed since 2001 and will operate until the fourth quarter of 2005, cannot be computed pursuant to FIN 46R due to lack of information. The entity’s activities consist of liquidating the assets of divested operations. Its original assets and corresponding liabilities and equity totaled €127 million. Management does not expect E.ON’s results of operations to be adversely affected by this entity’s operations.

Acquisitions, Disposals, and Discontinued Operations

Acquisitions in 2005

On February 22, 2005, E.ON Energie acquired 67 percent ownership interests in Gorna Oryahovitza and Varna, Bulgarian regional electric distribution companies. The aggregate purchase price of approximately €140 million was paid in 2004. The two utilities became consolidated E.ON companies on March 1, 2005.

In the first half of 2005 E.ON UK acquired, in two tranches, 100 percent of the equity of Enfield Energy Centre Ltd., which operates a gas-fired power station near London. With an installed capacity of 392 MW, the power station can generate enough power for 300,000 homes. The purchase price was approximately €180 million. Enfield Energy Centre became a consolidated E.ON company on April 1, 2005.

On June 28, 2005, E.ON Ruhrgas purchased a 30 percent ownership interest in Distrigaz Nord from the Romanian government for €125 million. On the same date, the ownership interest rose to 51 percent following a capital increase of €178 million. Distrigaz Nord became a consolidated E.ON company on June 30, 2005.

Discontinued Operations

On May 17, 2005, E.ON sold Viterra to Deutsche Annington GmbH. The purchase price for Viterra’s equity was approximately €4 billion. The total value of the transaction was approximately €7 billion. This figure includes interest-bearing liabilities and provisions to be assumed by the purchaser. The transaction received antitrust approval in early August.

On June 15, 2005, E.ON Ruhrgas sold Ruhrgas Industries to CVC Capital Partners, a European private equity firm. The purchase price for Ruhrgas Industries’ equity was approximately €1.2 billion. The total value of the transaction was approximately €1.5 billion. This figure includes net debt and provisions to be assumed by the purchaser. Management expects the transaction, which is subject to antitrust approval, to close in September 2005.

Both disposals are in line with E.ON’s strategy of focusing on its core power and gas business.

Interim Report 11/2005

Pursuant to U.S. GAAP, the income and expenses related to these operations are reported separately under “Income/ Loss (–) from discontinued operations, net.” The Consolidated Statements of Income and the Consolidated Statements of Cash Flows, including the notes relating to them, for the period ended June 30, 2005, and for the prior periods have been adjusted for these discontinued operations. The assets and liabilities of these discontinued operations are shown in the Consolidated Balance Sheets for the period ended June 30, 2005, under “Assets of disposal groups” and “Liabilities of disposal groups.” No reclassification of prior-year balance-sheet line items attributable to discontinued operations takes place, as such reclassification is not permitted by SFAS 144.

The following table shows the major line items of the statements of income of the above-named operations:

3		Reclassifaction of Ruhrgas Industries and Viterra as discontinued operations.

Intangible Assets

As of June 30, 2005, and December 31, 2004, E.ON’s intangible assets, including advance payments on intangible assets, and related accumulated amortization consist of the following:

Intangible Assets

	June 30,		Dec.31,
€ in millions	2005		2004
Intangible assets subject to amortization
Acquisition costs		4,664		4,544
Accumulated amortization		1,769		1,647
Net book value		2,895		2,897
Intangible assets not subject to amortization		822		891
Total		3,717		3,788

In the first six months of 2005, E.ON recorded an amortization expense of €175 million (prior year: €160 million) on intangible assets and a nonrecurring amortization expense of €0 million (prior year: €1.5 million) on intangible assets. We did not record impairment charges in the first six months of 2005.

Based on the current amount of intangible assets subject to amortization, the estimated amortization expense for the rest of 2005 and each of the five succeeding fiscal years is as follows: 2005 (remaining six months): €183 million, 2006: €317 million, 2007: €291 million, 2008: €214 million, 2009: €179 million, 2010: €154 million. As acquisitions and dispositions occur in the future, actual amounts could vary.

Treasury Shares Outstanding

As of June 30, 2005, E.ON AG held 4,374,398 treasury shares. E.ON subsidiaries held another 28,922,194 shares of E.ON stock. The increase in the number of shares held by E.ON subsidiaries is attributable to the on-market purchase of 450,000 shares of E.ON stock in connection with the voluntary share-exchange offer made to Contigas shareholders. In early July these shares were used to execute the share-exchange offer. E.ON thus holds 4.8 percent of its capital stock as treasury shares.

Dividends Paid

On April 27, 2005, the Annual Shareholders Meeting voted to distribute a dividend of €2.35 per share of common stock, a €0.35 increase from the previous dividend, for a total dividend payout of €1,549 million.

Payments into Pension Plans

In the second quarter of 2005, E.ON UK made payments of €629 million into the E.ON Holding Group of the Electricity Supply Pension Scheme. The payments cover a portion of the actuarial deficit of E.ON UK’s pension plans.

Asset Retirement Obligations

E.ON’s asset retirement obligations at June 30, 2005, relate to the decommissioning of nuclear power stations in Germany (€8,252 million) and Sweden (€389 million), environmental remediation at conventional power station sites, including the removal of electric transmission and distribution equipment (€332 million), environmental remediation at gas storage facilities (€78 million) and opencast mining facilities (€59 million), and the decommissioning of oil and gas infrastructure (€19 million). The fair value of nuclear decommissioning obligations was determined using third-party valuations.

An accretion expense pertaining to continued provisions of €250 million for the current period is included in financial earnings (prior year: €250 million).

Contingent Liabilities Arising from Guarantees

Financial Guarantees

Financial guarantees include both direct and indirect obligations (indirect guarantees of indebtedness of others). These require the guarantor to make contingent payments to the guaranteed party based on the occurrence of certain events and/or changes in an underlying instrument that is related to an asset, a liability, or an equity security of the guaranteed party.

E.ON’s financial guarantees include nuclear-energy-related items that are described in detail in our 2004 Annual Report. Obligations also include direct financial guarantees to creditors of related parties and third parties. Financial guarantees with specified terms extend as far as 2029. Maximum potential undiscounted future payments amount to €634 million (year end 2004: €737 million). Of this amount, €422 million (year end 2004: €534 million) consists of guarantees issued on behalf of related parties.

Interim Report II/2005

Indirect guarantees primarily include additional obligations in connection with cross-border leasing transactions and obligations to provide financial support, primarily to related parties. Indirect guarantees have terms up to 2023. Maximum potential undiscounted future payments amount to €466 million (year end 2004: €459 million). Of this amount, €94 million (year end 2004: €162 million) involves guarantees issued on behalf of related parties. As of June 30, 2005, we have recorded provisions of €92 million (year end 2004: €98 million) for financial guarantees. Provisions in the amount of €3 million are recorded as liabilities of discontinued operations.

In addition, E.ON has commitments under which it assumes joint and several liability arising from its ownership interests in civil-law companies (Gesellschaften bürgerlichen Rechts), noncorporate commercial partnerships, and consortia.

Furthermore, certain E.ON Group companies have obligations by virtue of their membership in the Versorgungskasse Energie Versicherungsverein auf Gegenseitigkeit (VKE) in accordance with VKE’s articles of association. Management does not expect these companies to have to perform on their obligations.

Indemnification Agreements

Contracts in connection with the disposal of shareholdings concluded by the E.ON Group companies include indemnification agreements and other guarantees with terms up to 2041 in accordance with contractual arrangements and local legal requirements, unless shorter terms were contractually agreed to. Maximum potential undiscounted amounts payable under these agreements could total up to €4,374 million (year end 2004: €4,602 million). These typically relate to customary representations and warranties, potential environmental liabilities, and potential claims for tax-related guarantees. In some cases, the buyer is either required to share costs or to cover certain costs before we are required to make any payments. Some obligations are covered first by insurance contracts or provisions of the divested companies. As of June 30, 2005, we have recorded provisions of €73 million (year end 2004: €86 million) for all indemnities and other guarantees included in sales agreements. Provisions in the amount of €13 million are recorded as liabilities of disposal groups. Guarantees issued by companies that were later sold by E.ON AG (or by VEBA AG and VIAG AG before their merger) are included in the final sales contracts in the form of indemnities (Freistellungserklärungen).

Other Guarantees

Other guarantees with an effective period through 2020 include contingent purchase consideration (maximum potential undiscounted future payments at June 30, 2005: €36 million; year end 2004: €36 million) and warranties and market-value guarantees (maximum potential undiscounted future payments: €98 million; year end 2004: €91 million). Other guarantees also include product warranties (€18 million included in provisions and €13 million in the liabilities of discontinued operations as of June 30, 2005). The change compared with the provisions of €25 million as of December 31, 2004, reflects additions to provisions of €9 million and the utilization and reversal of provisions of €3 million in the first six months of 2005.

Litigation and Claims

The arbitration proceeding between Fortum Power and Heat Oy (Fortum), Espoo, Finland, and E.ON Nordic is still in progress. Fortum, which wishes to exercise its purported rights under a call option agreement entered into in April 2002 regarding E.ON Nordic’s shares in E.ON Finland, initiated the arbitration proceeding in February.

Subsequent Events

On July 1, 2005, Sydkraft and Statkraft SF (Statkraft), Oslo, Norway, signed an agreement whereby Statkraft will acquire a total of 24 hydroelectric power plants from Sydkraft. Together, the plants produce approximately 1.6 billion kWh in a normal year. The purchase price for the plants amounts to approximately €500 million, before adjustments for assets and liabilities in the transferred companies. Plans call for Statkraft to take ownership of the plants on October 1, 2005.

In July E.ON UK acquired Holford Gas Storage Limited (HGSL) from Scottish Power. HGSL, a company formed to develop one of the country’s largest underground gas storage facilities, has already gained full planning permission to build such a facility in Cheshire in northwest England. The purchase price for HGSL is approximately €140 million (£96 million).

On August 10, 2005, E.ON decided to use the Group’s strong liquidity and financial position to fund up to €5.4 billion of its provisions for pensions by means of a contractual trust arrangement (CTA). The funding process will begin soon and be complete in 2006. The CTA will increase the transparency of E.ON’s balance sheet and further strengthen the financial security of employees’ company pension plans.

3		In 2004 writedowns impacting adjusted EBIT and earnings from companies accounted for by the equity method deviate from the corresponding figures recorded in the Consolidated Statements of Cash Flows and in financial earnings calculated pursuant to U.S. GAAP. The main factor is impairment charges taken by the Central Europe and U.K. market units, which is recorded under other nonoperating earnings.

Interim Report II/2005

U.S. Midwest primarily operates a regulated utility business in Kentucky, USA.

The Corporate Center consists of equity interests managed directly by E.ON AG, E.ON AG itself, and consolidation effects at the group level.

Under U.S. GAAP, E.ON is required to report under discontinued operations those operations of a reportable or operating segment, or of a component thereof, that either have been disposed of or are classified as held for sale. In 2005 this applies mainly to Viterra and Ruhrgas Industries for which sale agreements have been reached. For the purposes of our business segment reporting, our results for the six months ended June 30, 2005, and for the prior-year period do not include the results of our discontinued operations (see the table on page 30 and the commentary on pages 24-25).

Effective January 1, 2004, adjusted EBIT is E.ON’s key figure for purposes of internal management control and as an indicator of a business’s long-term earnings power. Adjusted EBIT is derived from income/loss (-) from continuing operations before income taxes and interest income and adjusted to exclude certain extraordinary items. The adjustments include book gains and losses on disposals, restructuring expenses, and other nonoperating income and expenses of a rare or extraordinary nature. In addition, interest income is adjusted using economic criteria. In particular, the interest portion of additions to provisions for pensions resulting from personnel expenses is allocated to interest income.

Adjusted Interest Income (Net)

January 1 - June 30
€ in millions	2005		2004
Net interest expense		–100		–289
— Net interest expense relating to liabilities of affiliated and associated companies as well as other share investments		–20		–16
— Accretion expense related to the adoption of SFAS 143		–250		–250
+ Income from long–term loans		26		43

+ Nonoperating interest income (net)1		—		43
— Interest portion of long–term provisions		–192		91
Adjusted interest income (net)		–536		–378

1 This figure is the sum of nonoperating interest expense and nonoperating interest income. In the first six months of 2004, nonoperating interest income (net) reflected, among other factors, tax-related interest payments.

The interest portions of the allocations of other long-term provisions are treated analogously to the degree that, in accordance with U.S. GAAP, they are reported on different lines of the Consolidated Statements of Income.

Page 7 of this report contains a detailed reconciliation of adjusted EBIT to net income.

Due to the adjustments made, our financial information by business segment may differ from the corresponding U.S. GAAP figures.
