Total Smart Grid costs. Source: EPRI. The Electric Power Research Institute (EPRI) has released a broad assessment of the costs and benefits to modernize the US electricity system and deploy the smart grid. EPRI’s Prism analysis estimates a potential CO 2 emissions reduction in 2030 of 9.3% Click to enlarge.

For example, a 2007 EPRI study they cite concluded that the US PHEV average fraction of vehicle miles traveled using battery electricity would be about 20%. There are also complex uncertainties in quantifying the consequences of adding load from PHEVs onto the electric grid in the US.

Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. A PHEV with only a 20-mile all-electric range is 62% lower (see printed page 95 in the 2004 study ).

J1711 was first approved in 1999, expiring in 2004, and had relatively little validation with plug-in hybrid vehicles. for reverse energy flow, e.g. vehicle-to-grid (V2G) or vehicle-to-home. for reverse energy flow, e.g. vehicle-to-grid (V2G) or vehicle-to-home. V2H) systems.

Power and Associates 2004 report ]. Despite this, a 2003 EPRI study , assuming only $2/gallon gas , zero buying incentives, and a PHEV premium of $3-$5,000 more than standard hybrids, shows that the total lifetime cost of ownership for a PHEV will be lower than that of any other vehicle type -- so the payback will be there.

Several dozen prototypes on 15-passenger van since 2004; now in second generation development; no production plans. Small long-term evaluation program, including modeling of vehicle-to-grid building benefits and economics, begun with Southern California Edison, joined by EPRI, other utilities, US DOE. Batteries not ready.
