The new framework agreement with Sweco commences in January 2026 and extends for three years. It means that Sweco and Vattenfall will continue their long-term collaboration covering the development, maintenance and innovation of Vattenfall's energy facilities. Sweco will provide expertise in several technical areas, with the aim of supporting Vattenfall's work to achieve net zero emissions by 2040.  

"Sweco has a long-standing collaboration with Vattenfall, and we are proud to yet again be selected as a trusted advisor in the ongoing green transition of Sweden's energy sector. We look forward to developing new solutions to the challenges facing both Vattenfall and the Swedish society as we move forward together on the path towards a sustainable energy supply," says Ann-Louise Lökholm Klasson, Business Area President, Sweco in Sweden.

Sweco will provide consulting services in areas such as wind power, hydropower, nuclear power, thermal power, electricity and heat distribution, new power and heat production, and final storage of spent nuclear fuel. The agreement is valid for an initial three-year period with options to extend for up to two additional years. The order value for Sweco is approximately SEK 600 million over three years.

Vattenfall is owned by the Swedish state and is one of Europe's largest producers and retailers of electricity and heat. The company is focusing on fossil-free energy and low-carbon solutions as part of the long-term transition to a sustainable energy system.
