The following will summarize the site visit made on Sept. 2, 1998, and list Some recommendations. It. Electrical Service A. NSP single phase primary line camas to a pole near the northwest comar of the cork. 1. Pole- mounted transformer that appears to be rated 15kVA. 2. 120/240 volt, single phase, 3 -wire overhead drop to a pole at the well site. 8. Pole at the welt site has the foilowing: 1 Tap to NSP pole- mounted lights for the parking lot • two floodlights on the pole. 2. Fo a riser that gees to a meter, 200A fusible switch and 200A panalboard that are mounted an an outdoor woad panel at the well site. 3. Pole riser that goes underground to the park shelter building that has a meter and 100A panalboard. III. Existing Lighting (doss not include the NSP Ilghtinaa) A Two poles on the south and or the existing parking lot, 1 Each polo has 3 luminaires; one to light the parking lot, and two that light the pleasure skating area, 2, One pole is near the well site, and the other is at the southeast corner of the parking lot. B Six poles each with two luminaires for lighting the hockey rink. Luminaires have metal halide !amps (1500W7). !V Park Shadier Building A. Most of the load the building is iighting. 5, There is a concessions room with electrical outlets; however, It is not used very often. V. Recommendations A. Have NSP provide the lighting for the new parking lot, There would be a mcn;h!y charge for the lighting, however, NSP would service and maintain the lighting. We can provide the lighting layout if the City would like for us to do it. E. Provide a 200A, 120/240V,ainggIs phase. 3 -wire underground service from the NSP pre with the transformer to the existing park smelter bu4ding, 1. Install a now 200A meter socket. 2. install a new 200A service panalboard and sUbfead the existing panalboard. 3. Move the c!rcults for the hockey rink lighting to the new panalboard, 4. A 200A service should be adequate to serve the anticipated loads. The largest single load is trio hockey rink lighting, and apparently there isn't much also on Except the warming rooms !n the shelter building. C. Wait until the next set of park improvements are designed to upgrade the electrical service. 1 These Improvements would include a new concessions building and bell field !igntm�. 2. A 3-phase electrical service will be required for the ball field ligRt!ng, and the Icgical panels and controls Is the concessions building. ,ocauon for the aervloe 3. Fa service were upgraded at this lima, the .,trryty would have to pay for the entire NSP costs because the would not be much Increase in the electrical load. In addition, the service would not be in the most desirable location. 4. If the upgraded service is installed with the now concessions building and ball field li ghting, thare will be an increase in the electrical load; NSP may not have to extend their overhead 3 -phase Fine; and the seccrdsry slectrrcal feeder may be shorter. In addition, there nig;nt not be any charges from NSP for providing the 3 -phase service. Vi Cost Estimate A. The estimated cost for the new service is $15.000.00. E. This estimate includes the fodowirg: 1. 200A direct buried underground service. 2, New 200A meter socket and service entrance panel. 3 Moving the hockey rink lighting to the new panel. This would Include new wiring from the existing smelter building to the fl rat pole on each side of the rink t
