RE: PX Computation:

We spoke with Roger Yang. They don't have anything on the shelf. I started to look at the PG&E web site and figured out that you'd have to have a PhD in Oper Research to re-compute the PX Credit on an hourly basis.

Jim,

Other than doing it in house, I would recommend MRW to compute the PX credit, which is a function of market purchases, CAISO charges, losses, load shape effects, etc.
