Quote:
A surge of wind last Monday afternoon jumped far beyond levels forecast by operators of Oregon's burgeoning wind-farm industry, sending more power into the regional grid than it could handle.
The Bonneville Power Administration is responsible for adjusting hydropower generation levels to accommodate the power from wind turbines so the system isn't overloaded.
It realized by Monday evening that it could no longer handle the surge without increasing spills of water through hydroelectric dams to levels dangerous to fish. Spilling the water keeps it from the hydropower generators.
