Seadrift is located on the Texas Gulf Coast with a population of 1,364 people as of the 2010 U.S. Census. In 2012, the city started operation of a $610,878 wind turbine, dedicated to its wastewater treatment plant. The city hoped to save $25,500 yearly using wind energy to displace some of the plant’s electrical demand. The plant’s average load is...

... Theodore Cleveland2, W. Ross Williams3 The city is about 3 meters (m; 10 feet [ft]) above sea level. Figure 1 is a map of the geographical location of Seadrift. The city's WWTP has a rated capacity of 0.3 MGD with an annual historical average use of 0.05 MGD or 17% capacity. ...

... also seen in both the Seminole and Seadrift studies, as shown in Figure 6 and Figure 7, respectively. For Seminole, an EW50 wind turbine from Entegrity Wind provided a portion of the electricity for a brackish water well and reverse osmosis water treatment system in a demonstration project. The minimum wind speed to generate power was 5.54 mps (18.2 fps), and wind speeds between that value and the cut-in value of 3.98 mps (13.0 fps) actually consumed small amounts of energy. In Seadrift, cut-in wind speed was 10 fps, while predicted wind speed was 21 ...

... the turbine produced a significant amount of energy, and the economic metrics for the projects are all positive when analyzed at the city level, as shown in the analysis of ECOE, NPV, IRR, and ROI. Figure 10 shows the COE by year, based on electrical bills per year provided to us by the city. Figure 10 shows a decrease in ECOE since the introduction of the wind turbine. ...

Figure 10 shows the COE by year, based on electrical bills per year provided to us by the city. Figure 10 shows a decrease in ECOE since the introduction of the wind turbine. Indeed, in the years 2009-2011, the COE and ECOE values were the same as the grid was the only source of electricity. ...
