The <br />transmission line rebuild is necessary due to increased electrical loads in the Connexus service area. Furthermore, <br />the age and marginal condition of the existing transmission line is a major contributing factor in this proposed upgrade. <br />In isolated cases, the existing line fails to meet new code requirements for ground clearance, posing a safety issue <br />that needs to be corrected. <br /> <br /> <br />Typical New <br />69 kV Transmission Structure <br /> <br />Planned Project <br />The eight mile segment of transmission line will be rebuilt with heavier conductor <br />wires connected to horizontal post insulators that are attached to new single <br />wood poles (see photo on this page). The typical height of the new poles will be <br />55 to 65 feet above the ground. In addition to the three energized wires, an un- <br />energized shield wire will be attached at the top of the pole. This wire is <br />grounded and provides lightening protection for the transmission line. The shield <br />wire will also incorporate a fiber optic communication line for monitoring and <br />operating the GRE transmission system. The transmission line voltage will remain <br />the same, and with few exceptions, the new poles will be on the same alignment <br />as the existing poles. <br /> <br />TreeNegetation Maintenance and Construction <br />There will be tree removal and trimming associated with this project. Prior to any <br />tree removal or trimming activity, a representative of GRE will directly contact <br />property owners to discuss the extent of the work. GRE construction personnel <br />will communicate and coordinate with the property owners along the transmission <br />corridor regarding access to the easement area. Fences may need to be <br />temporarily removed during construction. <br /> <br />Schedule <br />Construction activities will commence during the late Fall of 2006. The work will begin with tree removal and trimming <br />activity. Transmission line construction is scheduled to be completed by Summer of 2007. <br /> <br />Contact <br />Rick Heuring <br />Field Representative <br />GREAT RIVER ENERGY <br />763.241.2337 <br />rheuring@grenergy,com <br /> <br />9/6/2006 <br />
