Subject Area
The feasibility, cost, and air quality impacts of using electrical grids to shift water use from drought-stricken regions to areas with more water availability were examined. Power plant cooling represents a large portion of freshwater withdrawals in the United States, and shifting where electricity generation occurs can allow the grid to act as a virtual water pipeline, increasing water availability in regions with drought by reducing water consumption and withdrawals for power generation. During a 2006 drought, shifting electricity generation out of the most impacted areas of South Texas (~10% of base case generation) to other parts of the grid would have been feasible using transmission and power generation available at the time, and some areas would experience changes in air quality. Although expensive, drought-based electricity dispatch is a potential parallel strategy that can be faster to implement than other infrastructure changes, such as air cooling or water pipelines.

hello my name is that Casey I'm a graduate student the University of Texas at Austin on behalf of my co-authors I would like to introduce you to a feasibility study on how the spatial location of electricity could be changed based location of drought in order to increase water availability in those regions with just a generation is a major use of
fresh water resources in the United States due to the need for cooling water nationally power plants account for approximately 40 percent of water
withdrawals which the amount of water removes the source about 3 per cent of water consumption which the portion of water that is not return to the source which was 1 a drought occurs the amount of water available for
all users including power plants is reduced in the past insufficient cooling water
availability has cost power plant shutdowns this letter is a proof of concept the
lecture gate can use the virtual water pipeline
in essence the ideas additional water availability could be delivered to area with water concerns by shifting the location of electricity generation and its associated water he's away from that area to regions of relatively more water availability for this work texts
was chosen the demonstration case since they
self-contained electric work Khot the smallest model effectively but large enough to the results of a national scale It's insects experienced several droughts
in recent years including wondering June 2006 time period chosen for the study while a variety of
drought indices exist in this work utilize the U.S. Drought Monitor index for this episode during June 2006 all of Texas was classified as being under drought conditions with disparity ranging from abnormally dry the lowest intensity to exceptional drought bias intent for this work force in areas in which
electricity dispatch decisions were made based the spatial location of drought were compared to a model base case of grid operation without dropping constraint are results indicated that had efficient generation and transmission capacity in 2006 to be able to shift all lectures to generation away from regions with extreme exceptional drought which were located in south Texas during this in the base case these extreme exceptional drought regions including 10 % of Khot generation foreground water consumption for a
shift electricity generation away from the most intensive drought reasons could have provide enough water for domestic use of 360 thousand Texans in those areas in addition overall
consumptive water use electricity generation sector decreased compared to the base case though consumption increased in regions to which electricity generation was shifted changing the spatial location of
power plant generation and thus emissions during the episode also impacted regional ozone in 5 particular matter concentrations which are regulated due to the impact on human health and the
cost of a strategy examine this work was generally more than the insulation of air cooling technologies or the construction of physical pipeline deliver water to region with sustained drought however the drought
base changes never got to be a blend rapidly it would be able to be adapted based the spatial location of future droughts the economics is tragic to be
improved in future research by the money it only at night or during non-peak hours when baseload generation profiles exists rather than throughout all hours in the study cost increases Furkat during base load conditions were only 2 per
cent or 3 per cent compared base case costs will cost increases of 9 per cent to 45 per cent were modeled during peak hours in conclusion the
text selected great to be used in a virtual water pipeline to change worries patterns the
electricity generation sector in order to deliver increased water availability for other users in
drought-stricken regions although this project focused on Texas and changes in Khot shifting the spatial location of electricity generation in other grids could
also redistribute water usage in other drought-stricken regions
