If you are a PG&E customer, you either already have a so-called smart meter at your home or are in line to get one soon. PG&E has installed 5.6 million smart gas and electric meters so far and plans for all its 10 million customers to have them by 2012.
So what exactly makes a smart meter smart? Why are utilities across the country and around the world racing to install them? And what benefits are there for consumers?
PG&E says its SmartMeters will give consumers detailed information that will help them to more efficiently manage their energy use. But public reaction so far is largely negative, with many PG&E customers complaining of spikes in their bills. The consumer backlash now includes a small but vocal number of customers who don’t want the devices installed at their homes at all.
Meters that measure gas and electric usage at homes and businesses are the basic components of any power grid. Traditional electromechanical meters use gears and dials, much like the mileage odometer on a car, to measure how much energy is consumed over a given period of time, typically a monthlong billing cycle.
Those meters have been in place for decades, and they have been remarkably reliable. But the old meters have limitations. While they can keep track of cumulative energy consumption, they don’t have the capacity to store data on a daily or hourly basis.
“Traditional meters cannot measure consumption in time buckets,” said Ahmad Faruqui, an expert on the smart grid and a consultant with the Brattle Group in San Francisco. “They measure at the beginning of the month and the end of the month, and the meter reader comes at the end of the month.”
Smart meters, in contrast, use embedded software that records electric use by the hour and transmits the data to a nearby data collector, which then relays the information directly to PG&E through a secure wireless network known as RF (radio frequency) mesh. Soon, customers will have access to up-to-the-hour data on their electricity consumption.
“This is not just a new type of chip,” said Brian Seal of EPRI, the Electric Power Research Institute, a nonprofit research think tank for the utility industry. “It’s a shift in the definition of what we expect a meter to do.”
Once smart meters are installed, utilities will be able to offer “time of use” pricing, which will charge consumers higher rates for energy used during peak hours — typically late afternoon and early evening — and lower rates during off-peak hours.
Several pilot tests within the utility industry have shown that many consumers change their behavior to avoid the higher peak prices. Advocates say that will reduce the load on the power grid, prevent blackouts, offset the need for additional power plants and lead to a much cleaner environment.
But consumer advocates warn that many people — including small business owners, the elderly, the disabled and families with small children — won’t realistically be able to curtail their peak usage and will be unfairly penalized with higher bills.
“We’re only hearing about problems,” said Mindy Spatt of the consumer advocacy group TURN. “We’re not hearing that meters are helping people save energy or save money on their bills. From the consumer end, there doesn’t appear to be a benefit right now.”
But Helen Burt, PG&E’s senior vice president and chief customer care officer, says customers ultimately will benefit.
“Smart meter technology is the indispensable cornerstone of the smart grid — which will empower customers and utilities to manage energy use more intelligently,” she told state legislators last month at a hearing.
But PG&E’s rollout of smart meters has been rocky. The flood of complaints from consumers who fear their smart meters caused spikes in their energy bills led state regulators to order an independent investigation into meter accuracy that is now under way.
Earlier this month, PG&E acknowledged that as many as 23,000 SmartMeter customers may have received inaccurate bills.
For consumers, the main promise of smart meters is simply more information. Most people pay their monthly power bill without fully understanding how many kilowatt-hours are burned up by their flat-screen TV or window air conditioner.
PG&E says customers who have smart meters can, after about two billing cycles, go online and see exactly how much gas and electricity they have used, right up to the previous day, and they can track their electricity use hour by hour.
And starting this summer, customers with smart meters can sign up for “Energy Alerts” that tell how much energy they’ve used during the billing period, much in the way consumers currently check to see if they’re about to run out of cell phone minutes. PG&E has a five-tiered rate structure, and the text message or phone alerts can warn people if they’re about to move into a higher tier.
Other smart meter features are still a few years off. One is the “Home Area Network,” which will allow remote control of appliances equipped with communication chips. Users could use their cell phone to program their dishwasher to run at an off-peak time, for example, or to tell their air conditioner to turn on before they arrive home on a scorching summer day.
Utilities say smart meters will also allow them to pinpoint power outages and restore power faster during storms. Much of this will be done remotely, without the need for technicians to visit the home.

Direct Energy to unveil home energy manager for smart meters
If you have a smart meter on the outside of your home, you may soon be able to use it through a home entertainment terminal inside your home.
Houston’s Direct Energy will unveil a new home energy monitoring system with partners Whirlpool, Best Buy, Lennox and Open Peak on Thursday at the 2010 Consumer Electronics Show.
The terminal (it’s not clear from the press release if this is a television or computer monitor or what) is meant to be the technology center for the home, a place to download movies, get weather information, tweet, and manage the home’s energy use.
But the energy management portion goes beyond just shutting off lights. Connect the terminal to a smart meter, and the user could time appliances to turn on or off as power prices change throughout the day.
During the heat of the afternoon, when power demand peaks, power plant pollution reaches its height, and prices spike, the home energy manager could shut off lights and unnecessary appliances (like a pool pump). When power demand eases at night, and wind farms begin pumping out more clean energy, the home energy manager could automatically start the dishwasher, the dryer, and other appliances.
Direct said in a press release on Tuesday it will test the system later this year with homeonwers in Houston.
One thing Direct Energy has already learned: People don’t want to sit around thinking about electricity all day long.
“What’s most important is that the Home Energy Manager isn’t all about energy. As we’ve learned, this is a low-interest category for the average consumer,” spokeswoman Cybele Diamandopoulos said in an email.

POWER TO THE PEOPLE: Direct Energy, Whirlpool Corporation, Best Buy, Lennox, OpenPeak Launch “Home Energy Manager” Prototype for Consumers
Easy-to-Use Home Energy Management Solution Promises to Change Consumption Behavior and Save Consumers Up to 25 Percent on Energy Bills
LAS VEGAS, Nevada (January 6, 2010) – Energy consumption is a hot topic but, despite the hype around being more efficient and “going green,” the market has yet to deliver a one-stop, cost-saving, home energy management solution that’s easy for consumers to understand and use.
Direct Energy, Whirlpool Corporation (NYSE: WHR), Best Buy (NYSE: BBY), Lennox International (NYSE: LII) and OpenPeak – all leaders in their respective industries – are hoping to change that on Thursday when they unveil a prototype of the Home Energy Manager (HEM) at the 2010 Consumer Electronics Show (CES).
The result of an unprecedented, cross-industry collaboration, the HEM runs on OpenPeak’s OpenFrame device and is the world’s first truly consumer-friendly, end-to-end, coordinated home energy-management solution. Future plans for the prototype include a 12-month pilot in consumers’ homes in Houston later this year. The objective of the pilot is to learn how the HEM impacts consumer behavior in the real world, how much money each household using the HEM saves on its utility bills, and how the solution can be improved before it goes to market.
Developed with consumers at all income levels in mind, the HEM will demystify energy management, enable consumers to easily control their home energy use and costs, and receive the necessary information to change consumption behavior in a long-term and meaningful way.
The HEM is also designed to serve as an information and entertainment center in the home, providing access to news, weather, health, social networking, music and movie applications. In addition, there will be an online application store where consumers can build on the platform by downloading other applications that interest them.
“The Home Energy Manager has the potential to do for home energy management what the iPhone did for communication,” says David Dollihite, vice president of product development at Direct Energy. “We believe the Home Energy Manager will become the de facto platform that empowers consumers to look at energy use in a fresh, new way and modify their consumption behavior.”
According to preliminary data, the HEM prototype could save consumers up to 25 percent per month on their energy bill.
“The Home Energy Manager is the first solution that will make the energy-cost connection real for consumers, helping them convert kilowatts on their energy bill into dollars in their pocket,” said Dollihite.
The HEM leverages the opportunity created by the deployment of smart meters to residential homes, allowing consumers to track and control their energy use and costs on an easy-to-use, touch-screen device with an intuitive, graphic user interface. The solution works on an open platform and integrates easily and seamlessly with energy-connected home appliances, such as dishwashers, washers and dryers, water heaters, thermostats and heating and air conditioning units.
With the HEM, consumers will be able to manage their energy spending proactively by setting pre-determined budget limits and ensuring that appliances operate within specific parameters. Alerts will warn consumers when they are close to reaching their budget threshold for the month and offer personalized recommendations about how to reduce costs for the rest of the billing period. Consumers will also be able to program the system directly or remotely to avoid energy consumption during peak periods.
Each of the participating companies will provide the following support for the pilot:
- Direct Energy – pilot project management, consumer research with pilot participants, energy and home services support and OpenPeak OpenFrame devices
- Whirlpool – smart (connected) major appliances including, but not limited to, clothes dryers, water heaters, etc.
- Best Buy – OpenFrame device installation and integration associated with the pilot homes in the Houston market with first-line customer service through Geek Squad
- Lennox – wireless connected thermostats and full zone control High Efficiency HVAC in new construction homes
- OpenPeak – OpenFrame devices and application and hardware development, including application development of the HEM solution
“We have come a long way in making home appliances more and more energy efficient during the past 30 years,” said Warwick Stirling, global director of energy and sustainability, Whirlpool Corporation. “Connecting smart appliances to a smart grid will tap into a whole new level of energy efficiency. Tools such as the Home Energy Manager, which is easy to use and keeps control in the hands of the consumer, are paramount to the overall success of the system.”
“Our goal with the Home Energy Manager is to put the power of knowledge in the hands of consumers while removing the burden so often associated with energy management,” said Dan Gittleman, CEO, OpenPeak. “By giving people the right information in real time and in an easy-to-understand format, we will be able to help them put their energy dollars to work more efficiently and cost-effectively. Ultimately, this will translate to more responsible energy consumption, happier customers and more loyal consumers of energy-related products and services.”
Demos of the Home Energy Manager will be conducted in the Whirlpool booth at CES, The Las Vegas Convention Center, South Hall #36185MP, on January 7th and 8th.
