Presentation slides for its 2021 financial results report showed 2022 generation volumes for Isar 2 in E.ON's non-core PreussenElektra unit were sold at 56 euros ($61.47) per megawatt hour (MWh) as of Dec. 31, 2021.

Hedging rates of forward generation volumes are tracked by traders and analysts to assess what supply is tied up with counterparties and the value of future production.

E.ON's nuclear production in 2021 from Isar 2, a 1,400 megawatt (MW) plant able to power the equivalent of a metropolis, had fetched 49 euros/MWh.[POWER/DE]

But Berlin said last week that costs and risks of extending nuclear power outweighed limited benefits.
