Subject: RE: [energyinterop] Scope questions for discussion

Good discussion. A customer committed foreword
purchase can be quite different from a forecast. Some customers may be content to buy at
real-time prices. Others may decide
to hedge with a partial forward purchase and still other may speculate buying
more than they forecast and selling in real-time. Edward G. Cazalet, Ph.D. 101 First Street, Suite 552 Los Altos, CA 94022 650-949-5274 cell: 408-621-2772 From: Considine, Toby (Campus Services IT)
[mailto:Toby.Considine@unc.edu] No customer forecasts is today’s world, and is the reason
that DR is process rather than results oriented. What is a committed forward purchase, but a customer forecast?
What is a forward looking purchase to support an industrial process but a
customer forecast. What is service centric DR but a forecast with a promise? Toda’s utility was built upon all customer decisions being
mere noise in the over-abundance, With reduced operating margins stocks, that
overabundance is gone. With congestion pricing by a neighborhood, we have
reduced the crowd to individuals. tc "If flies are allowed to vote, how meaningful would a poll on

From: Ed Cazalet [mailto:ed@cazalet.com] The grid usually forecasts load in the aggregate. What is
the building forecast for? If it is a baseline for a DR program, then who
should be responsible for the forecast? The customer should not do it,
because of the incentive to bias the forecast. Edward G. Cazalet, Ph.D. 101 First Street, Suite 552 Los Altos, CA 94022 650-949-5274 cell: 408-621-2772 From: Considine, Toby (Campus Services IT)
[mailto:Toby.Considine@unc.edu] Traditionally, building load management has been crude, and
aggregated in certain large time granules. Industrial sites, however, have had
strong incentives to manage peaks. As operating safety margins get smaller, it may become
increasingly important to manage peaks aggressively, even within the
neighborhood or even home. Is some sort of detailed peak /load shape of
interest in the new world? What about power factors? Is the forward and backward
reporting of curves rather than points of measurement the future of smart
metering? tc "If flies are allowed to vote, how meaningful would a poll on

[mailto:skiliccote@lbl.gov] All,
David
Holmberg and I had a great conversation today on the scope of EI (which will
hopefully feed into section under discussion). I’d like to open up some
of my ideas and get your feedback before I propose a few paragraphs for the
scope section. I’d
like to look at the scope from a B2G interface point of view and the questions
I suggest we try to answer are:
Buildings’ need from the Grid: - Issue time,
start time, end time -
Within the start time and end time there may be a request from the grid
for load reduction (%, absolute, relative, etc) (or load increase - when there
is too much generation)
- Power quality (Do we care how “good” the power
we get from the Grid? Probably! What are the indicators to be communicated to a
building? Grid’s
need from buildings: -
Measured (current, historical) demand I
welcome your comments. All of the above assumes that the meter is the
demarcation point. And just to add, the expansion of this to DER can be again
categorized as on the utility side and on the building side but should be a
super set. |
