Why Has Columbia been at 65% For A month And A Half


Originally published 5/2

It just doesn't make sense to "coast down" for this time frame. I doubt the below from the NRC is truthful.   
"REDUCED FOR ECONOMIC DISPATCH COASTDOWN TO REFUELING OUTAGE"
Update: I talked to the senior resident inspector about this. Man, the Washington state electric system is a beast. The grid is owned by all of us and the DOE (Bonneville Power). Columbia is owned by Northeast Power. Bet you this setup is a artifact of the cold war and nuclear weapons production. The vast proportion of the juice in Washington is produced by their dams. As this time, there is extreme winter melt off. The dams can go full power at this time. Dams electricity is very cheap and Washington electricity is also cheap. They found it very economical to ramp down power from the Columbia nuclear plant and supply all of electricity from the dams in heavy meltdown. I wonder how they compensate Columbia for all the capacity factor it lost? This kind of dispatch(for this long) is very infrequent.
