Methodology to Answer
Question 1Estimate existing idle generation capacity in a NERC region using a “valley filling” methodology
System load profile data from NERC and EIA
Simplified hourly load profiles to two 24 hour dispatches,a typical summer and typical winter day
Simulate the economic dispatch of generators
Generation available to charge PHEVs = available capacity minus generation dispatched to meet load.
Assumed that peaking plants are not used to charge PHEVs

Findings Valley Filling can charge approximately 75% of all
light duty vehicles in the US, if they were PHEVs
Potential Gasoline Displacement by PHEVs = 6.5
Million Bbls per Day (71% of total gasoline
consumption)
Assuming utilities have some control over when
charging occurs, PHEVs could increase minimum
system load, thus increase the utilization of baseload
units, and thereby increase utility profits (and/or reduce
electric rates).
![Page 14: Plug-in Vehicles and the Electric Grid](https://reader035.vdocuments.mx/reader035/viewer/2022062315/56814e1c550346895dbb8230/html5/thumbnails/14.jpg)
Findings PHEVs charging on today’s coal-fired generation have about
33% lower GreenHouse Gas emissions per mile than conventional
vehicles, charging on gas-fired combined cycle, have about 78%
lower GHG emissions.
Deployment of PHEVs facilitates the introduction of more wind
energy in regions where wind generation is strong at night.
Distribution engineers have expressed concern that distribution
transformers may not be designed to sustain a constant high
loading without a daily “cool down” period.

GM’s Chevy Volt
• Unveiled as a concept car at the January Detroit Auto Show, the Chevy Volt would range 40 all electric miles, then a three cylinder gasoline engine recharges the electric battery.
