A largely residential feeder circuit may not be sized to have a significant proportion of its customers adding 1.4 to 6 kW loads that would operate continuously for two to six hours beginning in the early evening. Even if the overall region may have sufficient generating power, the region's transmission system or distribution lines to different areas may not be large enough to handle this new type of load. However, initial analysis shows that even charging at peak times may be less costly than using gasoline to operate the vehicles. Costs of generation also fluctuated greatly depending on the timing. Nighttime recharging had less impact on peak loads and generation adequacy, but the increased use of coal-fired generation changed the relative amounts of air emissions. If recharging occurred in the early evening, then peak loads were raised and demands were met largely by combustion turbines and combined cycle plants. Depending on the vehicle, its battery, the charger voltage level, amperage, and duration, the impact on regional electricity demand varied from 1,400 to 6,000 MW. To do this, we used the Oak Ridge Competitive Electricity Dispatch model, which simulates the hourly dispatch of power generators to meet demand for a region over a given year. We conducted an analysis of what the grid impact may be in 2018 with one million PHEVs added to the VACAR sub-region of the Southeast Electric Reliability Council, a region that includes South Carolina, North Carolina, and much of Virginia. Furthermore, the type of generation used to recharge the vehicles will be different depending on the region of the country and timing when the PHEVs recharge. Local distribution grids will see a change in their utilization pattern, and some lines or substations may become overloaded sooner than expected. They could require both the addition of new electric capacity along with an increase in the utilization of existing capacity. Depending on when and where the vehicles are plugged in, they could cause local or regional constraints on the grid. It is important to understand the ramifications of introducing a number of plug-in hybrid vehicles onto the grid. But this expectation does not incorporate that endusers will have control of the time of recharging and the inclination for moreВ В» people will be to plug in when convenient for them, rather than when utilities would prefer. However, there has generally been the expectation that the grid will not be greatly affected by the use of the vehicles, because the recharging would only occur during offpeak hours, or the number of vehicles will grow slowly enough that capacity planning will respond adequately. Plug-in hybrid vehicles (PHEVs) are being developed around the world much work is going on to optimize engine and battery operations for efficient operation, both during discharge and when grid electricity is available for recharging. Up to 25 coastal power plants and 86 substations are at risk of flooding (or partial flooding) due to sea level rise. We have identified some lines whose probability of exposure to fire are expected to increase by as much as 40 percent. A 5C (9F) air temperature increase (the average increase predicted for hot days in August) will diminish the moreВ В» capacity of a fully-loaded transmission line by an average of 7.5 percent.The potential exposure of transmission lines to wildfire is expected to increase with time. As the climate warms, California's peak supply capacity will need to grow faster than the population.Substation capacity is projected to decrease an average of 2.7 percent.

When generator losses are included in the demand, the ninetieth percentile peaks may increase up to 25 percent. As much as 21 percent growth is expected in ninetieth percentile peak demand (per-capita, exclusive of population growth). By the end of the century, electricity demand for almost all summer days is expected to exceed the current ninetieth percentile per-capita peak load. The maximum statewide coincident loss is projected at 10.3 gigawatts (with current power plant infrastructure and population), an increase of 6.2 percent over current temperature-induced losses. Some end-of-century impacts were projected:Expected warming will decrease gas-fired generator efficiency. This report outlines the results of a study of the impact of climate change on the energy infrastructure of California and the San Francisco Bay region, including impacts on power plant generation transmission line and substation capacity during heat spells wildfires near transmission lines sea level encroachment upon power plants, substations, and natural gas facilities and peak electrical demand.
