Sweden: Tradition by wind, dynamics by solar power
What drives this change is the need for electricity. It is growing strongly. According to the Swedish Energy Agency’s short-term forecast, electricity generation will grow significantly by 20283 - driven by industrial electrification, steel industry, battery production and data centres. Wind and water alone will not be able to fully meet this need.
This is where solar power comes in. By the end of 2025, Sweden had 5,541 megawatts of installed solar power1, still a modest share of the total mix, but with significant growth. Especially striking: The expansion of open-plant facilities larger than 1 megawatt increased by 128 percent in 2025 compared to the previous year. According to the Swedish Energy Agency’s forecast, solar power generation is expected to grow to around 9 terawatt hours by 2028. An increase of around 190 percent compared to 2023.3
Geographically, Southern Sweden in particular offers surprisingly good solar conditions. The countries of Västra Götaland and Södermanland, where Wingfields and Gas Light are built, are on a similar latitude to northern Germany. This is no coincidence: Southern Sweden combines hours of sunshine with grid infrastructure and industrial power demand.
The growth of small rooftop and household installations slowed down noticeably in 2025. The total expansion of all plants was only +15 percent compared to 2024, after 70 percent between 2022 and 2023.1 The growth driver is changing: away from the roof, towards the open area. Exactly where klimaVest is active.
