Sweden’s Vattenfall is planning to increase the power of the Forsmark-1 nuclear power plant by just over 100 MW, half of which can be done during the next maintenance period this autumn, the utility and nuclear operator said.

“We have the opportunity to increase electricity production for this reactor without major technical measures corresponding to the annual consumption in about 200,000 apartments or 50,000 houses,” Torbjörn Wahlborg, Nordic production manager at Vattenfall said.
