As a resident of Toronto, I am privileged to live in a house equipped with a Smart Meter provided by Toronto Hydro. I also work at Energy Circle, which means I have been witness to the extraordinary power of real-time monitoring. Yesterday, I contacted Hydro to find out when we could expect our Smart Meter to start providing us with real-time data about our electricity use, so that we could start to benefit from the lessons gained by tracking and reducing our energy usage. The news isn't great.
I should point out that we have been psyched about Smart Meters from the start. They have the potential to reveal to us the nuances of our electricity use, information that we can use to save energy and money. They are a resource, attached to our house by our utility, with seemingly endless potential for enlightenment. So those of us who have Smart Meters are the lucky ones. We are also after-thoughts.
The 64K question lurking in the shadows of the entire smart meter discussion is whether they'll be any benefit to consumers. Based on a discussion I had yesterday with Robert Cappadocia, it appears that the homeowner's ability to monitor electricity use so that you can save money in the future is purely incidental. According to Cappadocia, Supervisor of Smart Metering for Toronto Hydro, this is true not only of Toronto Hydro, but also of many of the early smart meters in the States. Don't get me wrong. It's not that you won't benefit from smart meters eventually, it's just that when they first went into service, they were meeting the needs of utilities that didn't want to drive to remote locations to read meters, or wanted to impose time of use rates. Will you benefit from smart meters? Yeah, eventually. Will you ever have real-time data? Probably.
Cappadocia illuminated a key misunderstanding about smart meters, the widely embraced gateway to Google Powermeter and GE Net Zero Energy Home among other energy management resources: It wasn't until they'd been bought and installed that some of the most useful reasons to have them became clear. "We were meeting a provincial mandate to provide time-of-use data for utilities," Cappadocia says. And frankly, that's all they were trying to do. Early smart meters (by which we mean 2005 installations) were stripped down in functionality to be cost efficient. That means that some of the most valuable functionality - and here, we're talking about things as basic as alerting the utility that the power was out - were deemed unnecessary. That's right. Generation I of Smart Meters in Ontario can't tell Hydro that the power is out. The customer still has to call. (When the power comes back on, the Smart Meter is clever enough to note that it fainted on the job).
There are a host of smart meters that can't be read remotely, because they aren't hooked up yet... but... wait for it... all of those smart meters (even the power blind ones) essentially have the capacity to provide consumers with real-time data about their electricity use. Toronto Hydro is piloting that use, with a very small pilot of In Home Displays that receive meter data "a couple of times per minute." (Capaddocia acknowledged that as currently configured, the In Home Displays work almost exactly like a TED, The Energy Detective). In other words... Smart Meters have the capacity to provide real time data in a basic format to consumers, right now. That service, provided to a handful of early adapters of the Hydro website, is separate from the utility-serving functionality of the Smart Meter, and there are no plans to implement this feature broadly.
Here's how Smart Meters work right now: data leaves my smart meter and travels to Hydro, which sends it to an IESO (Independent Electricity System Operator) which places the data into time-of-use buckets then sends it back to Hydro, which sends it to my screen, 24 hours later. Sound cumbersome? He thinks so, too. Hydro has the capacity to do everything the IESO does, and it looks forward to taking that role over. And by the way, even with all those steps... given that they're all really just electronic exchanges... why does it take so long?
Smart Meters send data every hour to a collector. There are 1,300 collectors, each of which is responsible for receiving readings from about 400 meters. So why isn't hourly data available? Because... "Hydro reads meters once a day." Turns out, 2 am is meter-reading time for Toronto Hydro. At 2am, Hydro calls the collectors to gather data. I wasn't sure I'd heard right. Call, as in telephone? "Yeah, we're using dial up." And for the foreseeable future, Cappadocia predicts that Toronto Hydro will continue to use dial-up. The result is 400,000 meters read in 2 hours, and no more estimated bills, which is a big improvement. It's also a far cry from real-time monitoring.
When will consumers get real-time monitoring? Cappadocia, who I must note was endlessly courteous and helpful, said that was a very good question. He also said that he agreed "absolutely" that real-time monitoring is the best tool for consumers. "It's far more valuable," than the current system of 24 hour later reporting. "I don't dispute that at all. I think we'll eventually get there." It's just... not the top priority. What is? Making sure that consumers get billed very precisely, and charged when they use electricity during peak hours ... creating a culture of conservation.
And when will real-time monitoring become the priority? When consumers demand it. Those in-home displays - they've been given to the early adapters of the website (read: the people who were on to it). If Hydro learns that consumers really want real-time monitoring, they'll respond. But it won't be quick, and it won't necessarily be easy. I caught a glimpse during this conversation of a hesitation I suspect many utility companies feel: people with data can be a real burden to call centers. "What if the information on your screen is different from the data on your utility's screen?" Indeed.

Very good article.
Posted by Rennocks on Jan 15, 2010 3:02amI monitor my Toronto Hydro useage on their site using a password.
What the article does not cover is the time of use rates are a rate hike of approx 24% for mid peak and a 36% rate hike for peak power useage.
Thanks @Rennocks. Sadly, this has been too often the case with early smart meter implementations. If the utilities aren't careful, smartmeters are going to be exposed as the most cleverly branded trojan horse for higher energy rates ever conceived.
Posted by energycircle on Jan 15, 2010 12:36pmSomehow, I'm not surprised by Toronto Hydro's perspective on this, since it seems to be shared by the few other utilities that I've heard talk about this (specifically, SDG&E owned by Sempra). From their end-- what's in it for them other than a couple of kWh's that they would otherwise love to sell you. Further, I imagine their perspective as--you, as an energy conscious consumer, are the least likely viable business case, and if you're so excited about saving all the energy that you already don't consume cuz your smart, then go get yourself a TED or E-MON or something you already have anyway.
I know in the States, it's also been caught up in the relationship between utilities and PUC's. Either the regulatory authority mandates smart meters and specifically how they should be deployed, or they allow utilities to be compensated compellingly for Time of Use reductions on a retail/residential level. I just haven't seen much of that happen yet, to the extent that I've been watching.
Lastly, here's an interesting/boring study I was involved with about California's automated demand response metering pilot back in the earlier part of this decade. In short-- it confirms just about everything that I'm sure you're thinking about the possibilities of smart metering+demand response in the home.
