TimberRock will not only monitor the output of its solar charging stations, but will also check how much stored energy is available and when it can sell this energy back to the grid in order to help meet peak demand. TimberRock will then manage its fleet of four Chevrolet Volts to help regulate energy flow and balance this system.

According to the company, the ability to control the Volts’ charging using software algorithms is made possible by Demand Response, an OnStar solution.

Demand Response will help TimberRock to start, stop and modulate the amount of charge going to a particular Volt in coordination with energy need.

Commenting on the development, General Motors Renewable Energy manager Rob Threlkeld said that the electric vehicle charging will be a combination of renewable energy and battery storage in the future.

"This project supports GM’s goal of using all factors of the charging equation: electric vehicles, solar power, and battery storage," added Threlkeld.
