Are you putting words in my mouth Tim.
The East is absolutely adamant about having a liquid real-time energy markets with a "real supply curve" and a "real demand curve" such that hourly clearing prices reflect the true economic value of the commodity. With respect to the number of hourly price signals within an RTO that is necessary, that is subject to much debate. Although I prefer a zonal model for simplicity reasons, the reality is that congestion is more prevalent in the East in most of the markets and in order to get a functioning real time energy market, we may have settle for a limited LMP, in which nodal pricing is necessary for managing the congestion, but proxy buses are created in zones (3-5 per RTO) for purposes of real-time energy markets. Our views, I believe, are still very much aligned, however, I need to make some progress on the creation of real time energy markets. The zonal markets implemented in NEPOOL and contemplated for ERCOT result in a mis-priced commodity with no "real" price signal sent to the market. Out of merit generation is and will continue to be dispatched because the congestion is managed through energy uplift payments (congestion price signal is not sent to the market). This results in a very inefficient commodity market where the consumer gets screwed and market makers can't price the commodity or transportation on a forward basis. I hope this clarifies any misunderstanding.
