Powerhouse controls will be of utility grade. The switchgear will be backed by a 125 <br /> volt DC service battery system for operation of essential features during power outages, <br /> specifically turbine shutdown and maintenance of flow in the canal system including the <br /> bypass roller gate. The control panel will be fitted with an automatic telephone dialer to <br /> alert of alarm conditions. A dial-in signal will allow remote monitoring of the plant <br /> including critical variables (e.g.bearing temperature,voltage, etc.)from any telephone. <br /> Substation and Transmission Line <br /> The power will be sold to Delta Montrose Electric Association (DMEA) (See Appendix <br /> G: Power Purchase Agreement). DMEA has a underground 12.4 kV line approximately <br /> 300' from the power house location. <br /> A switchyard will be constructed at the powerhouse with a transformer capable of <br /> stepping up the power generated at 4,160 V to the interconnection voltage of 12.4 kV. <br /> Design and engineering work performed specifically in support of this project is being <br /> conducted by Sorenson Engineering of Idaho Falls, Idaho. All project designs will be <br /> reviewed and approved by Reclamation prior to authorizing construction. Conceptual <br /> and final design will be developed for all elements of the project including the canal <br /> system, intake channel, intake structure, tailrace, powerhouse, turbine, generator, <br /> mechanical equipment, powerhouse electrical controls, and the substation and <br /> transmission line. In addition, Sorenson Engineering gathered hydrological data and <br /> modeled energy generation projections for the project. <br /> Cost Estimate <br /> Following is a breakdown of the capital costs for South Canal Site #5 Hydro Project <br /> provided by Sorenson Engineering. <br /> 1) Powerhouse and Intake <br /> a.
