Welcome to the Green Think Tank

Increasing prices of fossil fuels and concerns about pollution and global warming continue to drive huge interests in Green Living and Renewable Energy Sources. Energy conservation and smart energy usage will be key components of our energy future, and future generations will produce and consume energy in profoundly different ways than we do today. This blog has been created with the goal of presenting a myriad of current topics related to the Energy Revolution, and is intended to spark increased awareness and meaningful discussions.

The First SmartGrid City in the USA

The first SmartGridCity in underway in the USA, in Boulder, Colorado. SmartGridCity is the nation's first fully integrated smart grid community and will boast the largest and densest concentration of these emerging technologies to date. 

Xcel Energy is performing the nation’s first large test of plug-in hybrid electric vehicles (PHEVs) with vehicle-to-grid (V2G) technologies as part of its internationally recognized SmartGridCity project. PHEVs with V2G are able to both charge from and discharge power back to the electricity grid, making them sources of distributed generation.

Phase I of the project involves four cars. An Xcel Energy PHEV has already been converted to be V2G capable as part of the SmartGridCity demonstration home project at the University of Colorado (CU) Chancellor’s Residence. In addition, three Boulder County Toyota Prius PHEVs will have special inverters installed that will allow the utility to pull power from the battery of the car during periods of peak power usage. These converted vehicles will become energy storage devices used as part of the technology tests currently underway in Xcel Energy’s SmartGridCity.

Phase 2 of the project involves converting another 60 existing hybrid electric vehicles to PHEVs with V2G technology. The cars are part of the City of Boulder, Boulder County, the University of Colorado fleets. A mix of onboard V2G technology and smart grid charging stations will be used in this part of the project. The smart charging stations will be installed in several Boulder-area locations. In subsequent phases, the goal is to add another 500 PHEVs to the grid in Boulder and to test V2G technology on a significantly larger scale.

In SmartGridCity, there is the unique opportunity to test and demonstrate how plug-in hybrid electric vehicles with V2G capabilities can act as sources of distributed energy storage. The environmental benefits of adding these PHEVs to the SmartGridCity project will be significant. Beyond the overall reduction in emissions associated with transportation, PHEVs are excellent energy storage devices that will allow addition of even more intermittent renewable energy generation to the grid.

Partners for the project include, the City of Boulder, Boulder County, the University of Colorado at Boulder, the Governor’s Energy Office and the Colorado Department of Public Health and Environment.
