25 Improving efficiency Adding new transmission capacity is time-consuming and expensive. So INL wind power researchers are considering how to move more electricity through existing transmission lines. In areas where wind farms are being developed there is potential to take advantage of wind cooling on transmission lines concurrent with wind power generation. An increase in wind speed of 5 mph blowing at a right angle to a high- voltage line can cool the line enough to increase the amount of current it can safely carry between 30 and 50 percent. INL researchers are working with Idaho Power Company in a windy part of southern Idaho to translate detailed wind and temperature information into dynamic line ratings real-time estimates of how much current each 500-meter segment of high-voltage line can safely carry when wind power is being generated. The research could help make electricity more affordable and accelerate renewable energy projects. Transforming transportation systems INL is helping reduce dependence on imported fuels with analysis and technology innovations related to advanced vehicles alternative fuel development and improved energy storage technologies. Advanced vehicle deployment INL leads the Department of Energys Advanced Vehicle Testing Activity by collecting data and performing independent analyses of advanced vehicle fleet demonstrations across the country. Cost-shared partnerships with vehicle manufacturers charging infrastructure providers and universities encompass more than 100 industry government and academic partners. INL is collecting and analyzing data from more than 9000 electric drive vehicles and charging units. INL has collected roughly 30 million miles worth of data from 26 states and two foreign countries related to advanced vehicle operation maintenance fuel use and life-cycle cost.
