Congestion Wheels.

Hey Guys.

The ISO cutting our off-peak imports from PV has been an ongoing problem. Now that we are doing congestion wheels again we can finally do something to avoid these cuts using congestion wheels.

Normally the ISO will cut our Import and shift our load from NP15 (PGE1&2&3) across the path to relieve the congestion. If you submit a congestion wheel there cannot be $30 cong, thus they will not cut your schedule going in at PV. Instead of shifting your load the ISO will award your congestion wheel and everybody will be happy. It is important to make your wheel larger then your import to ensure that part of your import not getting cut. I would recommend to put in the max number of MW's you think you can buy in the North and get rid of in the Desert. Go big in the off-peak, we submitted 200MW wheels Saturday and I think its safe to do similar size most nights.
