Infrastructure B August 8, 2012 page 2 Wind Power (continued) CDP page 83: "The use of ÇUpolu Wind Farm was considered as back-up power for North Kohala. However, it was deemed not feasible because of potentially significant costs and technical hurdles to overcome. generators at ÇUpolu are of the ÅasynchronousÆ variety and HELCO system is Åsynchronous.Æ The wind farmÈs output varies with the speed creating synchronicity problems with the grid. The feed i HELCOÈs grid during normal operations is possible through a 60 H Åcarrier currentÆ which requires an external (HELCO) source of p operate. For the Wind Farm to provide back-up electricity when is not available, an on-site generator with a capacity equal to farmÈs output (3-5 MW) would have to run 100% of the time. In t dollars, an asynchronous back-up generator costs about $1 millio megawatt, or $3 to $5 million to back up the Wind Farm. The iss fuel availability, storage and hazmat considerations must be add Also, winds are unpredictable." II. Streetlights "There are 14 huge freeway-style streetlights at the entrance to or so lots in the Kawaihae Hawaiian Homesteads area. There's no else comparable all the way down the coast. Even the entrance t airport has only half that many light standards. Would you be w work to turn off all but one or two of these unnecessary and jar and all but one or two of the lights at the mauka entrance to Ko Ranch and to ensure that this kind of wasteful overkill by eithe or the County is not repeated in the future?" CDP Strategy 4.8, page 84: Goals include Rural Infrastructure Standards to maintain KohalaÈ character and its natural visual beauty. Specifically, the CDP "low profile minimal street lighting". The next Infrastructure B "Power, Viewplanes & Erosion Control" subcommittee meeting will be held on the second Thursday of the on September 13th, from 5:00 to 6:15 p.m. at St. Augustine's.
