As we’ve seen with the Volt and other green initiatives, GM is working to promote sustainability with perhaps its latest project being enablement of recharging from renewable energy.

On Monday, OnStar Communications contacted us and announced Volt owners “may soon be able to charge their vehicle using renewable energy.”

The actual time frame is "to be determined," but the kinks are being worked out by OnStar and a company called PJM Interconnection with 17 Chevrolet Volts operated by Google’s Gfleet.



 

The way it generally works is OnStar-enabled technology receives a signal from PJM Interconnection showing the percentage of available renewable energy on the grid.

Data from this forecast is downloaded to the OnStar cloud, or Advanced Telematics Operating Management System (ATOMS). OnStar uses this signal to simultaneously manage the charging of many Volts and to match the renewable energy availability.

OnStar says a mobile app could be used to alert customers when renewable energy is available.

Google’s Gfleet is based at the company’s headquarters in Mountain View, Calif., and as many of you know, Google is highly involved in other green projects and automotive experiments that include cars that drive themselves.

At the same time, Google is naturally willing to collaborate with real human drivers, as the species does not yet seem ready to go extinct.

This week, the OnStar-enabled fleet's technology will be demonstrated at the 2012 DistribuTECH Conference and Exhibition in San Antonio.

The public demo fits with an announcement by Nick Pudar, OnStar vice president of planning and business development, who said it is nearly ready for prime time.

“This demonstration shows that in the near future customers will have a real signal of demand for renewable energy,” said Pudar. “As customers configure their Volts to favor renewable energy for their charging cycle, this real demand signal will influence utilities to tap into renewable sources."

Note that Pudar says demand will prompt utilities to increase (now limited) renewable energy supply.

We asked Adam Dennison, an OnStar Communications representative who sent the info, “How hopeful are you that this will have a measurable or significant influence that it will push utilities to adopt more renewable energy sources?”

In response, he said “We think that as EVs continue to penetrate the marketplace that customers will drive a variety of demands throughout different industries. Certainly we believe that the energy industry will be one of these. Based on the level of interest a number of utilities have expressed in OnStar’s Smart Grid solutions, we are pretty confident that that they’ll be willing to look to more renewable energy sources.”

At present, peak hours for renewable energy generation from wind is generally between 10 p.m. and 6 a.m. according to PJM data.

OnStar says it would therefore be possible for customers to use Smart Grid solutions to further reduce their carbon footprint and – as is already possible regardless of energy source – “save money by charging during these off-peak times.”

“Solutions like this one will ultimately lead to increased renewable energy generation and allow Chevrolet Volt owners to be a key part of that energy transformation,” said Pudar.

If the renewable energy service goes into production, customers interested in using it would need to sign up. Dennison did not say if it would cost extra or be made available with existing OnStar service.

Once signed up, OnStar would regulate customers’ charging using the renewable energy signal.

This video is not directly about the current project, but OnStar says it highlights an app it did for Google's Gfleet of Volts.

OnStar says this renewable energy technology is the latest addition to its suite of Smart Grid solutions.

For your review, OnStar says it has developed other “intelligent energy management technology solutions,” including:

Demand response – This solution connects utilities to companies that have intelligent energy management products. These companies can use OnStar to manage energy use for Volt customers who opt in for the service. This future service allows the customer to save money on energy costs while enabling more efficient use of the electric grid.
Time-of-Use (TOU) rates – OnStar can receive dynamic TOU pricing from utilities and notify Volt owners of the rate plan offers via email. Owners will be able to use OnStar to load the rate plans directly into their vehicle and access them to schedule charging during lower-rate periods.
Charging data – OnStar also sends and receives EV data that helps utility providers without having to interface with the vehicle’s electric vehicle supply equipment. This includes location-based EV data that identifies charging locations and determines potential load scenarios.
