Subject: RE: [energyinterop] Time and Date and Scope

What is the scope
of eMIX? Is eMIX an abstract price
and product definition information model or is it an information model for a
priced offer and a transaction, for example. If eMIX models only price and product
definition then offer availability ( your question 1), execution interval (your
question 2) are part of Energy Interop. Otherwise, if eMIX models priced offers
and transactions then these attributes are part of eMIX. With respect to
question 3), I can post offers to buy at 15 min intervals or multiples of 15
min intervals. I can also choose to
ignore an offer to me that do not fit my 15 min rule. If I use non-standard interval definitions
I may get no offers or acceptances of offers in which case the power I buy or
sell is transacted in the imbalance market at the resolution of my meter and
the imbalance market intervals.
Where to put standardize interval definitions gets back to the question
of what is the scope of eMIX? Your suggested
answer to question 4) seems to conclude that eMIX should model bids or offers. As I think priced
offers and transactions are at the heart of any implementation in Energy Interop, then priced offer and transactions could be central
focus of eMIX. What are the other applications
of eMIX price and product definitions?
Edward G. Cazalet, Ph.D. 101 First Street, Suite 552 Los Altos, CA 94022 650-949-5274 cell: 408-621-2772 From: Toby Considine [mailto:tobyconsidine@gmail.com] On
Behalf Of Toby Considine I may offer to provide power with certain attributes
any time. I may offer to provide power with certain attributes for the
next 3 weeks to sell my on-site generation during the annual maintenance period
for my chemical processing plant. 1) When
I put an offer out on the street, I may accept bids for the 24 hours. That is a
market detail that is not part of the underlying offering. Definitiel not part
of EMIOX. Is it part of Energy Interop? 2) I
may take several hours after bid closing to “fit” the bids before
execution. That pre-announced execution date (bid opening?) is a market detail
that is not part of EMIX. Is it part of Energy Interop? 3) I
may want to specify that I will accept only committed bids for intervals at a
granularity of at least at least 15 minutes, or multiples of 15 minutes (which
is not the same). I think that those facts are probably part of EMIX.
Icould accept arguments that they are part of Energy Interop. 4) There
are markets where the entire window of availability must be bid alongside
individual calls against that availability. This describes certain DR markets
as well as that chemical plant above. I think the window of availability is
part of EMIX or EnergyInterop. I tend toward the former, but I could be
convinced otherwise. Please discuss on the list, with an answer for each. tc "Energy
