German energy giant E.ON AG (EOAN.XE) said Wednesday 2011 operating earnings will decrease by up to 16% on the year, but added that it expects profits to recover in 2012 after bottoming out this year.

Poor margins in its wholesales gas and power generation businesses as well as a new nuclear fuel tax in its home market, will hit profits in coming years, said E.ON. At the same time, E.ON offered a more positive outlook after 2011 than German peer RWE AG (RWE.XE).

In 2011 adjusted earnings before interest, taxes, depreciation and amortization will decline to between EUR11.2 billion and EUR11.9 billion compared with the EUR13.35 billion recorded last year, said the company.

Adjusted after-tax profit is expected to decrease by up to a third to between EUR3.3 billion to EUR4 billion.

E.ON added, however, that cost cuts and accelerating earnings from its Russian power plant fleet and renewable energies will help return the company to earnings growth in 2012.

Germany 's largest utility by market value has previously said it will also seek to expand operations in emerging markets, where growth is expected to be stronger than in its core European markets.

In 2013 adjusted Ebitda is expected to rise to at least EUR13 billion, E.ON said.

At 1242 GMT, E.ON shares were down .76% at EUR22.94 as the German bluechip index DAX traded .17% higher.

E.ON's shares have declined around 10% over the past 12 months, underperforming its Euro Stoxx Utilities peer group by around three percentage points.

E.ON's medium-term guidance was considerable more upbeat than that of its main domestic competitor RWE, which two weeks ago drew a much bleaker picture.

On Feb. 24 RWE said that earnings are expected to fall by nearly 50% through 2013 and aren't expected to improve before 2014.

Profit margins of European power generators have come under pressure in the last year, as power prices lag the renewed increase in coal and oil prices--which increases the cost of producing power--and demand still hasn't recovered to pre-crisis level.

E.ON said Wednesday that at present power generation margins the "major part of [the] European thermal power plant fleet is only able to cover fixed costs" due to the free allocation of carbon dioxide emissions allowances.

From 2013, full auctioning of carbon dioxide allowances will further eat into profits of power generators and E.ON said it expects some power plants will then become unprofitable and be decommissioned.

So far utilities have been granted most carbon credits for free under the E.U.'s emissions trading system.

In response to the worsened trading conditions E.ON, RWE and other German utilities have pledged to sell assets, reduce dividends as well as investment budgets and further cut costs.

E.ON also said Wednesday that net profit in 2010 fell around 30% on the year due mostly to lower disposal gains than a year earlier and impairment charges on assets in southern
Europe incurred in the third quarter.

Net profit came in at EUR5.85 billion, down from EUR8.42 billion a year earlier. The figure exceeded the EUR4.88 billion average forecast in a Dow Jones Newswires poll of 13 analysts.

Adjusted for impairments, gains or losses from asset disposals, the revaluation of energy derivatives and restructuring expenses after-tax profit was EUR4.88 billion, down around 4% on the year.

Revenue in the 2010 was EUR92.86 billion, up 16% from EUR79.97 billion a year earlier.
Analysts had forecast revenue of EUR83.62 billion.
