Business area Generation manages Vattenfall's hydro and nuclear assets. In 2025, Vattenfall's hydro power plants in the Nordics and Germany produced a total of 37.3 TWh (34.7) of electricity, supported by an installed capacity of 8,800 MW as well as 2,800 MW pumped hydro capacity. At year-end, Vattenfall's reservoir levels stood at 69 per cent (82 per cent), which is 11 percentage points above the long-term average.Nuclear power generation in Sweden amounted to 40.2 TWh (37.9), with a combined installed capacity of 5,500 MW. These results reflect Vattenfall’s commitment to reliable, large-scale fossil-free electricity production.

Business area Markets maximises the value of Vattenfall’s portfolio by optimising, trading, hedging and sourcing for Vattenfall, third-party assets, and sales positions.

Strategy and targets

Vattenfall’s ambition is to be a global leader in nuclear and hydro power operations, with a strong focus on safety, sustainability, and cost-efficient fossil-free electricity production. The safe decommissioning of closed nuclear reactors and management of spent fuel and nuclear waste are key responsibilities.

Business Area Markets enables decarbonisation by developing fossil-free and renewable offerings, such as biomethane and corporate power purchase agreements (cPPAs), and builds robust and diversified revenue streams by improving our optimisation and trading capabilities. Another key focus area is capturing the value of flexibility in Vattenfall’s hydro power plants and wind farms. We relentlessly strive to increase process automation by further leveraging artificial intelligence on secure and robust IT platforms.
