It doesn’t take too long for visitors of Mueller, a 700-acre master-planned community in Austin, to realize that the neighborhood is peculiar.
The planned community, built on the site of the former Mueller airport, boasts almost too-perfect rows of homes with cheery pastel exteriors and quaint front porches. And then there are the neighborhood’s green flourishes—solar panels that adorn every other rooftop and the eco-friendly hybrid cars that roll almost silently through the development’s tidy streets.
Mueller isn’t just a subdivision—it’s a life-size green energy research test site. The New Urbanist, a mixed-use development, is home to a five-year “smart-grid demonstration project” led by Pecan Street, Inc., a nonprofit research and development organization focusing on green energy, and Austin Energy.
In late July, General Motors announced that it is partnering with Pecan Street, making 100 Chevy Volts available to Mueller residents to buy or lease. Since February, Pecan Street has been providing financial incentives for residents to join, matching the $7,500 federal tax credit extended to owners of electric vehicles with their own $7,500 rebate. Those who opt to lease will receive a $3,000 rebate.
Mueller’s 600 residents are currently using about sixty electric vehicles, according to Colin Rowan, Pecan Street’s director of communications, and 52 of those vehicles are Volts.
Now, the recent influx of electric cars in Mueller has allowed Pecan Street to test the impact that high concentrations of electric cars might have on the area’s smart energy grid.
“We’re interested in how the grid performs when you have a lot of electric vehicles pulling power in one area, and how people use them and charge them,” Rowan said. “That sounds kind of basic, but it actually puts some interesting stress on the grid. We’re very interested in finding out how that can be optimized so that it is actually a benefit to the grid and not a liability.”
The Statesman adds on.
For 16 years, OnStar has been communicating with GM customers in their cars, usually in times of emergencies. But now the company is re-imagining itself to also be an energy manager for a fleet of electric vehicles.
The electric vehicle market is minuscule today, but some day, they could potentially serve as a fleet of mobile batteries that could store power until it is needed by a homeowner or grid operators during peak power demands.
Until now, OnStar’s experiments have been limited to small demonstration projects or work in the lab. Now they want to begin test-driving their theories with Austinites.
“This partnership provides us with a unique opportunity to observe charging details with many real customers in a concentrated setting,” said Nick Pudar, OnStar vice president for strategy and business development. “We are moving our lab demonstrations into the real world.”
Among the possibilities are taking advantage of different rates for different times of day for cheaper charging, and using the stored energy in car batteries to help power one’s house or give back to the grid in times of high usage. This real-world experiment is set to run through the end of 2014. Very, very cool.
