I think the issue is lower level - do you an open loop or a closed
loop system?
The OpenADR Feedback mechanism (adapted with appropriate standards
use for PAP03 and PAP04 in EiFeedback in Energy interoperation) does
that loop-closing with the ability to set one time or periodic
response schedules.
I think that's what Dave is getting at.
Thanks!

I
thought the CSP’s earned their profit by buying curtailment
in the retail market and selling it at a profit into the
wholesale market. I think you folks should visit the Board
of Trade in Chicago and learn how the big boys do it.
Don’t forget to bring your checkbooks.
And
don’t worry, it’s not as wild and wooly as it used to be.
They’ve stopped dropping truckloads of corn on the unlucky
speculator’s front lawn in suburban Highland Park.

Just a note—I
was looking at a recent PJM white paper on price responsive
demand:
http://pjm.com/~/media/documents/reports/pjm-whitepaper-on-price-responsive-demand.ashx
PJM is stressed
about not being able to correctly model price responsive
demand (PRD) and thus wants info back from the customer. From
page 11-12 I quote (and have highlighted what they expect from
the facility). This is the only place I know where I have seen
written down a request for feedback in some format. The PRD
Provider would be someone like an ESP or CSP.
“In real-time operations, it is
essential to understand how much energy will be consumed at
or above various prices so that PJM can send out the proper
price and dispatch signals to market participants to
maintain energy balance and reliability. Without this
information PJM may be in a position of ―over- or
under-dispatching‖ resources, rather than
dispatching the amount necessary to maintain energy balance.
The
PRD curves submitted by the PRD Provider, which include
price-quantity pairs, enable short-term load
forecasting to account for reactions to dynamic retail
rates. The below figure illustrates what such a PRD curve
might look like. PJM
