Two unplanned outages at key reactors in Sweden and Finland sent Nordic power prices to their highest levels since March, just as a cold snap engulfs the region.

Vattenfall AB’s Ringhals-4 nuclear reactor shut early Wednesday after a failure, while Teollisuuden Voima Oyj’s Olkiluoto-3 went offline during testing in the afternoon, according to regulatory filings with the Nord Pool exchange.
