<br />TRANSMISSION FACILITIES <br />In conjunction with the construction of Cambridge <br />Station, area transmission lines will be rebuilt and <br />upgraded to modern standards. The project will include <br />improvements to approximately 47 miles of existing 69-kV <br />transmission line in the area. The voltage of these lines <br />will remain the same, and the improvements should <br />require no new line corridors. Improvements may include <br />changing the poles, upgrading the wire size and adding <br />lightning protection to improve the overall operation and <br />reliability of the Cambridge area transmission system. <br /> <br /> <br /> <br />The photo above shows a <br />typical existing <br />transmission line. The <br />photo to the right depicts <br />a typical upgraded <br />transmission line for the <br />prQject. <br /> <br /> <br />ABOUT THE LOCATION <br />The Cambridge site was selected for several <br />reasons in addition to its close proximity to a fuel supply. <br />An existing Great River Energy peaking facility is already <br />located at the site, making for efficient operations. By <br />expanding the existing substation on the site, regional and <br />local area transmission systems will benefit without the <br />construction of new transmission lines. <br />The project also will include water storage <br />equipment, a generator step-up transformer and <br />modifications to Great River Energy's existing shop <br />building. <br />Cambridge Station will be constructed on land <br />Great River Energy currently owns. Additional land may be <br /> <br /> <br />purchased to support construction activities and to ensure <br />that future development by others is maintained at <br />an appropriate distance from the facility. The natural gas <br />supplier for the plant will acquire easements for the <br />installation of 0.5 to 1 mile of underground gas line that <br />will run from the proposed generating station south to an <br />existing gas line. <br /> <br />ABOUT GREAT RIVER ENERGY <br />Great River Energy is a not-for-profit wholesale <br />electric cooperative, serving 28 distribution cooperatives in <br />Minnesota and covering 60 percent of the state, <br />geographically. It is the second largest power supplier in <br />Minnesota. <br />Over the last 10 years, Great River Energy's peak <br />demand has grown an average of 5 percent. By comparison, <br />national electric usage grew at just over 2 percent per year, <br />according to the Energy Information Administration. <br />For more information about this project and Great <br />River Energy, visit: IfMIW.GreatRiverEnergy.com or call 763- <br />241-2200. <br /> <br /> <br />Cambridge Station will be located acfjacent to an existing <br />peaking plant owned by Great River Energy. <br />
