Subject: RE: [energyinterop] RE: Algorithmic price signals
This
is one of those occasions where I wish I could be in two places at one
time. Anyway, based on reading the email exchanges, and fully aware that
we're talking about possibilities here, there may be a few practical issues to
bear in mind.
California is the only market where the utilities run the DR
programs. Elsewhere, these prices are set at auctions, as you know, and
the trend (or reality in several programs now) is for DR resources to react
automagically when the price feed reaches the commitment value, or that in
reliability settings everyone gets the price set by the highest accepted
bid. This is true even where the utility acts as the CSP. There are
bilateral programs in non market areas, but I'm not sure there is much of a
return on trying to encompass the variations in all those.
Keeping up with tariff structures will drive us crazy. We have
folks that do this for a living, and I cannot tell you how often we, the
utility, and the customer cannot manually calculate an invoice and reach the
same result. As you know, commercial invoices often are done in Excel
because no one can agree on what to tell the programmers to structure in billing
systems. I am aware of one IBM plant that has its electric bill based on
the water consumption of the chillers. Given that audits typically show a
percent of commercial utility bills are inaccurate (this listserv doesn't go to
any utilities right?), this is far from an exact process.
DR
response tends to come from a different mix of local assets than those involved
in consumption. It is likely that a tariff constructed around the latter
would be misleading in calculating the former. Since outside California, the
prices are set in the wholesale market, the majority of those interested (and
who are not yet aware of OpenADR) would have no need for a derivative
capability.
Overall, the longer it takes to establish a national OpenADR
standard, the more likely markets outside California will be to have moved
beyond the point of economically justifying adoption. My
recommendation would be that we give priority to a "good enough" standard to get
established, then revisit this topic.
