Plan and Budget for Installing P&R's Aquatics Division has not developed Partially <br />Additional VFDs or implemented a written plan for installing Implemented <br />We recommend that the <br />Department of Parks & <br />Recreation, Aquatics <br />Division, develop and <br />implement a written plan for <br />installing VFDs at all County <br />operated swimming pools. <br />Then incorporate the plan <br />into future fiscal years' <br />budget that will reflect the <br />installation of VFDs and <br />reduction of electricity <br />expenditures. <br />VFDs at all County operated swimming <br />pools. However, in early 2016, P&R <br />installed a VFD at Kona Community <br />Aquatics Center (KCAC). In the next four <br />months, P&R realized a significant electricity <br />cost savings of approximately $2,400 per <br />month, or a 21 % savings. (Figure 1). <br />Furthermore, P&R purchased and installed <br />a replacement VFD for their Laupahoehoe <br />Swimming Pool in October 2017. Our <br />analysis showed that the average monthly <br />electricity cost decreased by approximately <br />$400 (15%) after the VFD installation. <br />(Figure 2). <br />In addition, we confirmed that Kawamoto <br />and PCAC pools currently running with <br />VFDs are continuing to recognize a cost <br />savings. In 2016 and 2017, the average <br />electricity costs were approximately $4,000 <br />(Kawamoto) and $5,000 (PCAC) - about <br />50% less than without the VFDs. <br />
