Opinion: Xcel`s ‘pricing challenge` is challenging indeed
In the last weeks, many of us received robo-calls from
Xcel promoting their “Pricing Challenge,” a by-product of the SmartGridCity.
This two-phase program is an attempt by Xcel to determine the effects of higher
pricing during times of peak electricity use. It will cost $1.5 to $2 million,
and be paid for by Xcel customers. It is being promoted through an expensive
mailer, whose beautiful design is unfortunately missing important pieces of
information.
This is not the first time that Xcel has studied
time-of-use (TOU) rates, and such rates have been used by other utilities for
decades. Unfortunately, it is not clear exactly what new information Xcel
expects to gather.
I was curious whether people who have photo-voltaic
systems could participate in this Challenge, so I asked my friend Ken Regelson,
a sustainable energy consultant. Regelson had already called Xcel. “After about
20 phone menus and talking to two people, I did talk to an informed phone rep.
According to her, customers with PV cannot participate in the Pricing
Challenge. The phone rep was not clear on why solar owners need not apply and
was quick to agree that a kilowatt-hour (kWh) generated is equivalent to a kWh
saved or shifted, and that she didn`t make the rules but would be happy to pass
on my concerns.” Also, per my own inquiry, customers who have already committed
to conservation with Saver Switches (Xcel-controlled switches that cut off
certain loads during peak times) are excluded.
So how will customers determine how much electricity
they use at various times during the day so as to be able to evaluate the
potential benefits (or costs) of the various Pricing Challenge schemes? I
checked Xcel`s Web site to see whether their SmartGridCity data would allow me
to see how much I used during Xcel`s “red light” peak period of 2 p.m. to 8
p.m. Since I have a “smart meter” (really just a remote-read meter), the data
is there, even if not available in real-time. But to analyze it would require
hand tabulating the numbers individually for every 15 minute interval for every
day, as I could find no way to either integrate the data on site or download it
to a spreadsheet.
Unfortunately, the mailer lists rates for the Pricing
Challenge schemes but not the ordinary rates. So doing a comparison requires
adding up the six digit decimals on my bill to determine the current rates.
Regelson`s perspective was interesting. “I think a
residential customer just doesn`t use enough per day to make it worthwhile to
pay attention. For the average residential user, even if you were to shift ALL
of your energy use out of the “red light” times, your savings would be less
than 50 cents per day under options 1 and 2, but the cost to you if you used
much electricity during red light times could be high indeed.”
Under option 3, for system “Peak Energy Events,” you get
paid to reduce below your average use level, defined as “the average of your
electricity use during your five highest peak period times from the previous 10
weekdays.” If some of these were “Peak Energy Events” for which you already cut
use, your average is apparently reduced, and then so is your next rebate,
unfortunately for you. Challenging enough?
Boulder has by far the highest Windsource participation
rate in Xcel`s Colorado territory, and the Pricing Challenge only applies to
Boulder SmartGridCity customers. But I couldn`t find any information on
Windsource in the mailer. According to the Xcel rep I talked to, the Windsource
premium is added on to all Challenge prices, but the effect on rebates is
unclear.
The mailer asserts that participation in the Pricing
Challenge can help “reduce our impact on the environment.” This didn`t sound
right, as I know that peak demand (which Pricing Challenge addresses) is met by
natural gas turbines, not coal-fired boilers, so I checked with Regelson. “If
you actually reduce your total usage and aren`t simply shifting it to other
times, then there is a marginal reduction in emissions – less gas is burned.
But if you are simply shifting load from peak to off-peak, then you are
shifting from gas to coal, and actually increasing local pollutants and toxic
metal emissions as well as CO2 and other greenhouse gases.”
The Pricing Challenge simply did not get the critical
review it deserved, and we will pay for that.
