Good morning, everyone.

As part of the RTCTF meeting for 10/30, we were planning to have initial discussion on the AS Demand Curve for Regulation Down.  We were interested to see if any of the task force members had particular proposals that they would like to present at that meeting.  If you are interested, please let Matt and I know and we'll be sure to have you marked down on the agenda.
