German utilities E.ON AG (EOAN.XE) and RWE AG (RWE.XE) have agreed in principle to transfer power production quotas from E.ON's decommissioned Stade nuclear power plant to the Biblis A reactor, which would allow RWE to operate Biblis A longer.

E.ON's new Chief Executive Johannes Teyssen Thursday told shareholders at the company's annual general meeting that the two utilities have reached an agreement, but added that the contract hasn't yet been signed.

The deal would allow RWE to operate Biblis A longer than is currently legal under
Germany 's existing nuclear phase-out laws.

Under the laws, all of the country's remaining 17 nuclear plants will have to be shut down by around 2022. Biblis A is the country's oldest operating reactor and would be one of the next nuclear power plants to be shut down.

Chancellor Angela Merkel's government, however, has pledged to postpone the nuclear phase-out to help the country achieve ambitious climate change targets. The government plans to present an energy roadmap this autumn, which is expected to include details about a possible postponement of the nuclear exit.

RWE has been pursuing a multi-track strategy to achieve a longer operating life of its 1.2 gigawatt reactor Biblis A.

In March RWE said it will run the reactor at reduced capacity, adding this would allow it to operate the power plant for about a year as opposed to only six months if the facility were to be operated at full capacity.

E.ON's Teyssen also Thursday said that the company doesn't expect the Kruemmel nuclear power plant in northern
Germany to resume power generation before the end of 2010. "We assume that Kruemmel won't be back online before Jan.1, 2011," Teyssen said.

The 1.3 gigawatt reactor Kruemmel, which is operated by E.ON's competitor Vattenfall Europe AG, was unexpectedly shut down in July following a technical fault at the 25-year power plant only 10 days after the end of a two-year shutdown caused by a similar problem in 2007 and which started a fire at the plant.

Teyssen's expectation for a relaunch of Kruemmel is more cautious compared with forecasts by Vattenfall last month. On Apr. 23, a spokeswoman for Berlin-based Vattenfall Europe said the company expects the reactor to resume power production in the fourth quarter of 2010.

E.ON and Vattenfall own 50% in Kruemmel each.
