Subject: RE: [smartgrid-discuss] Pricing standards
Is DR a charge, or is it an incentive. I am of the opinion that
it is an incentive. Here is the logic. Last week I contracted with my supplier to get apples at a given
price each week. Based upon that price I ran store specials and pre-sold apple
pies for Christmas. This week my supplier alerts me that he cannot fulfill his
contract, and I start looking for liquidated damages… Instead of merely stiffing me, the supplier calls all the apple
stands and bakeries in the city and sees which ones are willing to sell back the
apples they have contracted for. The initial contract was for $1 a bushel, and
he needs to buy them back for $1.50 a bushel, but it is worth it to keep the customers
happy with the supplier., and to avoid liquidated damages. Alternately the supplier could find another source of apples in
Washington State and pay extraordinary shipping charges to make the original
contract I would argue that in traditional GAAP, the sales are still at a
dollar a bushel. I could chose to add the shipping charges to Costs of Goods
Sold, or I could create some sort of extraordinary cost line to hold the
emergency buy-backs. If I understand the various market operation DR scenarios… -
Supplier could send around a notice of willingness to buy out of
previous contract. -
Supplier could have a Dutch auction until the clearing market for
additional buyers is found -
Supplier could exercise existing call options on certain
customers to get the apples to meet the contracts. Whether the existing customer just happens to be the one who has
advertised the apple buys for sale, i.e. is the customer who was being shorted
is an irrelevant detail. This removes DR from Egg Math into a simpler model of two
transactions that may happen to be with the same person…and I believe eliminates
the difficulty you outline tc "A man should never be ashamed to own that he has been in
the wrong, which is but saying ... that he is wiser today than yesterday."

Holmberg Hi Toby,
Some thoughts for now, I think we have to remember that we get the greatest
interoperability from a *light* interface. David, I am new to this group. Just to provide some background, I am
on IEC TC 57 WG 13, 13, 16, and 19. Your doc mentioned TC 57 so I thought I would forward two things
that I think are relevant: 1) A recent copy of the IEC 61970 Common Information Model.
This is the data model described in UML that TC 57 uses for enterprise
integration. There is some modeling related to schedules in the CIM.
This is an Enterprise Architect file. 2) A recent paper about ADR. This paper discuses the use of
OPC Unified Architecture (OPC UA). OPC UA is the web services version of
the services IEC 61970 specifies for exchanging CIM data. OPC UA is also
known as IEC 62541. While OPC UA is new, it is likely to be widely
supported by industrial control system vendors. As such it is a good
choice for DR related communication with industrial customers. You should know that EPRI and the IEC are beginning to actively
work in this area. We probably want to figure out how things fit together
at some point so that we don't end up doing the same thing twice. Regards, John

[smartgrid-discuss] Pricing standards All, As part of the discussion on smart grid economics, in
addition to schedules is the more general topic of pricing. I have written up
some thoughts on what we need to do to move forward on pricing. Part of this is
getting some standardized schedule as Toby mentioned. Perhaps a pricing
standard will end up in OASIS as well. Does everyone know about the GridEcon
meeting being planned for March in Chicago? The plan is to come with a pricing
proposal in hand to that meeting, and I believe there is significant work to
tackle prior to that time. Your input is appreciated. David David Holmberg NIST Building & Fire Research Lab Building Environment Division, Mechanical Systems and Controls
