Some electric companies are working
to put smart meters on our homes.
They want to change how we use
electricity hour by hour. Eventually,
power companies will charge more
when demand for electricity is highest.
Mark Brush reports on a new study
that looks at how people are responding:
Connecticut Light and Power tested the smart grid on about 3,000 of it’s customers. Half of them residential and half of them business customers.
They found that people did respond to high rates during high periods of demand – such as from noon to eight pm.
Jessica Cain is with Connecticut Light & Power. She says there seems to be a limit to how much they’ll change. For example, doing laundry late at night seemed to be a non-starter.
“Doing your laundry after 8pm would be a barrier. And we heard that from customers, both from a residential customer side and then from a business customer side. We heard that changing their business hours outside of that twelve to eight window would be very difficult.”
The power company found the most energy was saved when the utility itself used the smart meter to shutdown things like air conditioners during periods of high demand.
The customers said they liked the “set it and forget it” approach – so long as they could override the system if they needed to.

Micky Maynard is a reporter
for the New York Times. She’s been keeping a
diary of giving up her Lexus SUV for a hybrid
gas-electric car. She’s taken her readers on
a ride through her reasoning for switching
and her on-road experiences. The Environment
Report’s Lester Graham took a ride with Maynard
in her Barcelona Red Toyota Prius:
Micky Maynard: “Okay, so, to start it, you push this button. You see
the little ‘ready’ button, and you hear a little sound, and that’s
essentially the battery starting the car. And, off you go.”
Lester Graham: “I recall, when I was younger, I went from a pretty
powerful car to a little car, and the one thing I really noticed was
that it felt like I was driving a toy. What’s the difference between
driving the Lexus and driving this one?”
Maynard: “A difference is that in the Lexus, or in a SUV, you’re sitting
up above the ground. This car, you’re right back down on the road.
And it took a lot of adjusting. I was driving from Detroit to Chicago,
and I heard this ‘thump, thump, thump,’ and I thought I had a flat
tire, but it was just the road surface. Because I was used to sitting
up high, I never would have noticed the road bed before.”
Graham: “I know that some newby Prius drivers that when they
come to a stop, like we are now, there’s almost no sound
sometimes.”
Maynard: (laughs) “That’s right. In fact, my postman was telling me
hybrid cars will come up behind him, and he says, ‘they’re sneaky
little cars.’ He said, ‘you can’t hear them.’ (laughs)
Graham: “What’s it like going on to the on-ramp on the interstate?”
Maynard: “I haven’t had any trouble yet, because I generally try to
give myself enough space between myself and the person behind
me. You know, when you’re in a luxury car, a Lexus, you hit the
pedal and you get all this acceleration. This car’s quite peppy, but it
doesn’t have that rrrrrrrrrrrr that you get in a V8 or a V6. And that is
something to get used to.”
Graham: “I keep hearing from Prius owners that the consumption
meter really changes how they drive. How has the feedback from
the car affected how you drive?”
Maynard: “It affects how I drive tremendously. There’s a
consumption screen in the car, and it will show you exactly the kind
of miles-per-gallon you’re getting. So, if you don’t floor it, you can
get 100 miles-a-gallon – at least that’s what the car’s telling you. And
you have another meter that shows you what you’re averaging over
your trip. My pride and joy was driving a long trip and getting over
50 miles-a-gallon. And you kind of feel this little shot of pride when
you see the 50 or the 47.”
Graham: “So, you’re encouraged to take it easy just so you can be
rewarded with the feedback?”
Maynard: “And I don’t want people to think that Prius owners are all
out there going 17 miles-per-hour. We’re not. What’s going on is
we’re trying to drive smoothly, we’re trying to drive in a steady
fashion. Although they tell you that you get better gas mileage in
town, driving around city streets, I’ve actually gotten fantastic gas
mileage just driving steadily on the highway. You do keep the
consumption meter up on the screen, and you do watch it. Now, I
did have one reader write in and say, ‘stop watching the screen and
watch the road,’ and I assured her that I absolutely do watch the
road. But you do sort of glance over and kind of check how you’re
doing.”

A growing number of electricity customers in Ontario are using so-called smart
meters, which
will charge more for electricity used during peak hours of the day. The Great Lakes
Radio
Consortium’s Karen Kelly reports:
Right now, electricity customers in Ontario pay the same amount to run their
dishwasher at 6 p.m.
– during peak hours – as they do at ten in the morning. But it costs the province
more to produce
that power during peak times.
The heavy demand is a strain on Ontario’s aging electricity plants. So, the
province plans to
install smart electricity meters in every home and business over the next five years.
Ted Gruetzner is with the Ontario Ministry of Energy.
“It allows people to track their energy use depending on the time of day and monitor
when they’re
using power so they can turn their lights off at certain times or use their ovens or
dryers at
different times of day.”
That’s because electricity used during peak hours will cost consumers more. Ontario
is the first
jurisdiction in North America to use this system.
For the Great Lakes Radio Consortium, I’m Karen Kelly.
