**IMPORTANT**
All, I didn't catch the impact of this when I first saw it last week, but NYISO is making a change that should cause real time prices to increase (relative to historical prices) in cases where bid load is less than real time actual load. They will be committing GTs in the reliability pass of SCUC at an incremental cost of zero (instead of committing a steam unit), which increases the likelihood that GTs will run in real time under these conditions, increasing real time prices. The change goes into effect today or tomorrow. See below. Scott =========================================================================== pmorrison@nyiso.com writes to the NYISO_TECH_EXCHANGE Discussion List: Dear Market Participants, Please note the changes below are planned for the indicated OASIS/MIS/CSS systems on the dates shown.
