Pecan Street provided an additional rebate of $7,500 for the purchase of a Volt and a $3,000 rebate for residents who leased a Chevrolet Volt for three years or more. Pecan Street also offered a limited number of rebates for the Nissan Leaf and Prius PHV.

Pecan Street is part of Austin’s 700-acre sustainable Mueller community, where residents agreed to be part of a test bed for sustainable living. Other partner companies such as Sony, Whirlpool, Oncor and Intel provided Mueller residents with forward-looking smart grid and clean energy products and services.

Supported by a $10.4 million smart grid demonstration grant from the Department of Energy (and more than $14 million in matching funds from project partners), researchers from the University of Texas, the National Renewable Energy Laboratory and Environmental Defense Fund will study these products and systems to learn how they interact with the grid. Over five years, researchers will test up to 1,000 residences in and around the Mueller community.

We hope Pecan Street’s research will speed up the innovation cycle around smart grid and consumer electronic technology. Electric vehicles represent a significant addition to home’s energy profile and understanding that impact and how consumers use and charge their vehicles is critically important.

GM and OnStar’s official partnership allows researchers from Pecan Street and GM to study how these families’ Volts interact with the smart grid on a daily basis and how they interact with other sustainable technologies.

This partnership provides us with a unique opportunity to observe charging details with many real customers in a concentrated setting. We are moving our lab demonstrations into the real world. We’re gathering information from families’ vehicles throughout this community to find out the direct impact the Volt has on the grid and how to get drivers the lowest-possible charging rates. This project will also help us develop future capabilities of the Volt and other plug-in electric vehicles.

OnStar, which recently opened its Smart Grid APIs for utilities and energy companies (earlier post), has already developed a number of grid-relieving solutions, including charging with renewable energy, energy demand response, time-of-use-rates, and home energy management. The partnership with Pecan Street will allow OnStar to test these smart grid services in everyday scenarios.

One of the first demonstrations we will test will be to marry home energy consumption data and the Volt’s vehicle consumption to optimize whole-home energy cost and efficiency. We’re also excited to leverage our Smart Grid APIs with other partners in this project.

More than a third of the homes in Mueller have rooftop solar collectors, and Pecan Street will evaluate how solar and electric vehicle charging interact. This will allow customers a new, cost-effective way to generate energy, potentially powering their Volts at low or no cost while relieving some of the burden from the electric grid.
