Just got a smart meter here and love that I can now see a graph of hourly usage.
I really think if the power companies gave out (at a reduced cost & installed) some sort of power meter inside your house, we'd see a 10/ 20 / 30% (pick a number) reduction in electric usage.
I know from driving a hybrid with a MPG meter, I've(along with the car) improved about 20%.
The TED product looks interesting.
I got a ted 1000 and man what a RIP. It worked great until we realized that if we had even a 1 second power outage the TED would reset all the data and then recompile new data based on current usages. We where so perplexed when one day we saw the overall consumption for the first 20 days of the month was low then all of a sudden the next day the bill was up by 30%. Finally figured out that after a power Dip it just uses the current consumption and recalculates at that rate for 21 days.
Called TED and they said hook it to a PC and have it monitor the current via USB! I responded is'nt that a waste of power having a OPC on 24/7, the guy chickled said there was nothing else that could be done it has no built in storage. I said it says so on your web page he said not for the collected energy usage.
BTW a UPS wont solve the problem.
I have heard that in europe they have experimental systems being used in small towns that can shut off your power or restore it without them leaving the chair.
Sure, they can shut off all your power by killing the circuit remotely, but they can't kill an individual appliance inside your house.
A TED 5000 is still subject to not getting data when the power is off, but it stores it in non-volatile memory. It can also gets the date / time from an Internet NTP server (but right now - it has one heck of a time getting the correct day of the week). Also, the Footprints software is actually a WebPage
on the TED5000 Gateway, works with Windows, Macs and Linux.
Just ordered one!
In the Wall Street Journal this morning:
I came home from a trip to New England this past week to find that my meter had been swapped out for a smart meter.
My only annoyance was that the power company, Portland General Electric, didn't send a postcard. Admittedly the information may have been in the bill, but I don't often read the electric bill if everything seems to be in order.
PGE (as opposed to PG&E) has long talked about their desire to charge based on time of day and now they may be getting closer to either implementing it or not needing to do it.
Are you sure it does not lose all the Data during a power outage? The 1000 loses everything and then recalculates it back based on the current consumption. IOW if you run your AC and all the power hogs 24/7 for 28 days and the TED 1000 says your bill is approx $350. If you have a 1 second power dip on the 29th day and for the next 2 days all you use is the lights, TV and No AC or anything else, the TED will now tell you your monthly bill will be $70. (Worthless)
I can unplug my TED5000 gateway and it does not lose data. I can kill the main breaker and the Ted5000 will not lose data. Any other questions ?
Just installed T5000 today. . . interesting piece of instrumentation!
I saw the old TED, the new 5000 looks sweet. I dont need a display, the web access looks awesome.
Anyone find any deals cheaper than the $199 direct?
I don't think you'll find it cheaper.
Web access works fine - we do not have the standalone display and don't miss it at all. If you use Firefox (not the beta version) - there is a toolbar addin Ted the Toolbar. Works fine also.
Word of advice - do NOT change the default NTP service the gateway is setup with.
Is it buggy with other NTP servers or what?
Anyways, looks cool...just wish it was a bit cheaper. $199 is a lot and I dont think I would save that much on my energy bill...more just curiosity.
Meter reader showed up the other day while I was outside. Asked him about the switchout to digital meters. He said they were working on the substations apparently before they started placing meters.
Wasn't too happy about them since he would be out of a job once they went on-line.
Ahhh, the good and the bad of technology upgrades.
Around here the gas company has been contracted to read electric meters for some time now. They used to take turns (or maybe it was the same person driving the other company's rig).
I'm not too concerned about privacy issues and would greatly prefer greater utilization and more intelligence built into our electrical distribution system. I think outage management and service restorations would benefit. Hopefully it would help create a more efficiency so we'd have less loss in the system. Since the cable guys pretty much have a monopoly on broadband in our neck of the woods, I'd be happy to have our public electric utility as a competitor. I'd also welcome time of day rates. And if the Narcs smoke a few pot growers along the way, well so be it. (Just kidding. In Seattle, marijuana is way down the list of criminal offenses.)
This is what my utility, PECO (Philadelphia Electric Company) is doing in this regard:
In one of the largest investments in company history, PECO plans to install more than 1.6 million residential and commercial smart meters, deploy advanced communications networks, and utilize the latest in digital smart grid technology. The $650 million plans, filed this month with the U.S. Department of Energy (DOE) and Pennsylvania Public Utility Commission (PUC), could save customers about $1.5 billion during the life of the project, improve service and benefit the environment.
The company’s plans include building an advanced metering infrastructure (AMI), providing smart meters for 600,000 customers by 2012 and all 1.6 million customers in 10 years, and upgrading the company’s electric transmission and distribution system with the ability to identify and correct certain system problems before they impact customers.
The first plan, filed with the DOE, seeks $200 million in matching funds through the federal stimulus grant program. Included in the submission are letters of support from nearly 100 organizations including: members of Congress; city, county and state officials; chambers of commerce; and vendors. A stimulus grant would allow for a faster, wider smart meter and smart grid deployment.
The stimulus application also includes several private-public partnerships that would:
support low-income customers involving the Philadelphia Housing Authority as well as suburban county housing and social service agencies,
fund advanced energy management systems, and related applications and research at Drexel University and the University of Pennsylvania,
allow for technology demonstrations at 10 commercial office buildings owned and managed by Malvern, Pa.-based Liberty Property Trust,
sponsor job-training opportunities to support rapid smart-meter installations, and
pursue targeted customer deployment and renewable energy applications with Ben Franklin Technology Partners, Delaware Valley Regional Planning Commission and others.
PECO’s smart meter plan, submitted to the PUC on August 14, seeks approval to install the advanced metering infrastructure, backbone communications network and information systems to integrate customer energy usage with utility operations. The communications networks – fiber optics and wireless – will enable two-way communication between the smart meters and the smart grid.
These efforts support a broader environmental initiative at PECO and also are a component of Exelon 2020: A Low-Carbon Roadmap, the comprehensive environmental strategy of PECO’s parent company. Exelon 2020 sets the goal of reducing, offsetting or displacing more than 15 million metric tons of greenhouse gas emissions per year by 2020. This is more than the company’s current annual carbon footprint and is equivalent to taking nearly 3 million cars off American roads and highways.
I hate for anyone to lose a job, but around here, the meter readers were terrible. I used to have two and three misreadings a year. One resulted in my power bill being over five times what it should have been. The power company refused to correct the bill based on my reading because they said I was, "probably not capable of reading it properly." They said that if it had been misread that it would "work itself out" with the next billing cycle. This was even after I tried to explain that with a 200 amp panel, I would had to have been pulling almost 80% of that capacity 24 hours a day to have a bill of that amount. Luckily, my brother works there and was able to pull some strings to get the bill corrected. Since the digital meter was installed, I've had no issues at all,.
