Forecast briefing

as of May 1

Reduced power output is expected on May 2, May 9, and May 13.

Key risk days

WatchMay 2(94.3%)
The model predicts a lower chance of full power output in one day.
WatchMay 9(92.0%)
The model predicts a lower chance of full power output in nine days.
WatchMay 13(92.7%)
The model predicts a lower chance of full power output in thirteen days.

What is driving this

Warm river-water trend over the past month
Recent river water temperature
Recent air temperature
River flow rate over the past two weeks

Bottom line

The plant is expected to operate near full capacity for most of the next two weeks, but reduced output is expected on May 2, May 9, and May 13. Monitor river temperatures and flow rates, as these are key factors influencing the forecast. Consider lining up backup power supply in advance for those dates.
