Renewably Powered I Photovoltaics <br />Photovoltaics <br />Renewable energy plays the important role of offsetting remaining carbon emissions after building load reductions and electrification has been made. This can be handled through a variety of avenues - behind -the -meter systems, Community <br />Solar Gardens, and utility subscriptions. Since City of Louisville already offsets its current electricity with renewable utility subscriptions, the focus was on customer -owned, behind -the -meter systems that would provide more value to the City of <br />Louisville. <br />On -site Versus Grid Purchase <br />Some of the benefits of on -site solar vs renewables purchased from the grid are listed below. <br />• Avoid solar sprawl at scale - avoiding offsetting of impacts to rural areas. <br />• Avoid electrical energy loss due to transmitting power over long distances. <br />• Dispersed approach is typically grid beneficial, especially when on -site renewables are a small percentage of the total usage of building - most solar on this bldg would be self used. <br />Enable future resiliency through addition of batteries and storage. <br />Demonstrate decarbonization to local Louisville community. <br />High Priority Sites PV Array Locations 375 <br />kW <br />High priority sites were recommended based on the following considerations: <br />Financial and technical feasibility r r <br />kW Existing) <br />• Impact & considerations with land development <br />Proposed <br />Array <br />Cost <br />Array Type <br />Array Size <br />Production <br />Estimate <br />Facility <br />1-1 <br />[kW] <br />[kWh/year] <br />[$] <br />Art Center <br />None <br />- <br />City Hall <br />None <br />- <br />- <br />- <br />City Services <br />Ground <br />286 <br />315,000 <br />$870K <br />Coal Creek Golf Course <br />Ground <br />202 <br />252,000 <br />$1.211 <br />Library <br />Roof <br />128 <br />174,000 <br />$520K <br />Sid Copeland Water Treatment Plant <br />Ground <br />375 <br />559,000 <br />$1.3M <br />Police and Municipal Court <br />Ground <br />257 <br />397,000 <br />$910K <br />Recreation and Senior Center <br />Ground <br />380 <br />569,000 <br />$1.2M <br />Howard Berry Water Treatment Plant <br />Ground <br />200 <br />302,000 <br />$750K <br />Wastewater Treatment Plant <br />Ground <br />690 <br />1,026,000 <br />$2.1M <br />CITY OF LOUISVILLE I FINAL REPORT V3 1 INTERNAL DECARBONIZATION PLAN 120 <br />33 <br />
