Swedish Nuclear Power: Real-time Energy Production Monitoring
Sweden operates six nuclear reactors across three power plants, generating approximately 30% of the country's electricity. This dashboard provides real-time monitoring of all Swedish nuclear reactors, including Ringhals, Forsmark, and Oskarshamn power plants. Track current power output, reactor status, maintenance schedules, and energy production data from Sweden's nuclear fleet.
About Swedish Nuclear Power
Sweden has been a pioneer in nuclear energy since the 1970s, with nuclear power playing a crucial role in the country's energy mix. All reactors are operated by major energy companies including Vattenfall AB, Uniper SE, and Fortum Sweden AB, ensuring reliable electricity generation for Swedish households and industries.
Nuclear power in Sweden has a long and fascinating history that began in the 1950s when the country first explored nuclear energy. The first commercial reactor, Oskarshamn 1, was commissioned in 1972, marking the beginning of Sweden's nuclear era. During the 1970s and 1980s, several reactors were built, including Ringhals 1-4 and Forsmark 1-3, making Sweden one of the world's leading nuclear nations. Following the 1980 referendum on the future of nuclear power, it was decided to phase out nuclear power, but several reactors continued to operate. During the 2000s, several older reactors were shut down, but the remaining six reactors have been modernized and had their lifespans extended. Today, Sweden's nuclear fleet consists of both pressurized water reactors (PWR) at Ringhals and boiling water reactors (BWR) at Forsmark and Oskarshamn, representing decades of Swedish nuclear technology development and experience.
Swedish Nuclear Reactors Overview
Ringhals
Ringhals nuclear power plant, located in Varberg, Hallands län, operates two pressurized water reactors (PWR). Ringhals 3 and Ringhals 4 are among Sweden's most powerful reactors, with a combined capacity of 2,200 MW. These Westinghouse-designed PWRs provide reliable baseload power to southern Sweden.

Forsmark
Forsmark nuclear power plant, situated in Östhammar, Uppsala län, operates three boiling water reactors (BWR). As Sweden's largest nuclear facility, Forsmark provides significant electricity generation capacity to central and northern Sweden. Forsmark 1 was commissioned in 1980, followed by Forsmark 2 (1981) and Forsmark 3 (1985), making the facility one of Sweden's most established nuclear power plants.
