Orange County-Solar Feasibility Study Submitted by Pisgah Energy 4 <br /> PISGAH ENERGY <br /> n..9 YGN s bF.V.fLO YMf.N'd' <br /> July 3rd, 2025 <br /> Orange County <br /> Attn:Angel Barnes <br /> RE: Solar Feasibility Study <br /> RFQ No: 367-005449 <br /> Solar Feasibility Study Services for Orange County and Town of Hillsborough <br /> Scope of Work—Basic Services <br /> The scope of work for basic services is for solar feasibility study services requested in RFQ No. 367-005449 and is <br /> based on the (19) facilities identified by Orange County staff. The (19) facilities reflect the removal of Central <br /> Recreation, Fuel Station and Hillsborough Commons from the studies.This revised proposal also includes the following <br /> (4)facilities to be studied for the Town of Hillsborough; Town Hall Annex(rooftop solar only- 1 utility account) , Motor <br /> Pool (rooftop solar only— 1 utility account), Water Treatment Plant (ground-mounted solar only— 5 utility accounts), <br /> and Wastewater Treatment Plant (ground-mounted solar only— 1 utility account). The Price includes provision of all <br /> labor,preliminary design,site assessment equipment,and software tools to complete the services.The system designs <br /> provided with the feasibility studies will be based on the 2023 National Electric Code,the 2024 NC Building Code, and <br /> current AHJ (Authority Having Jurisdiction) requirements.We anticipate these services will last up to 18 weeks. <br /> 1) Kickoff Meeting—Key team members will be identified and discussions around site/facility accessibility will occur at <br /> kickoff.The schedule for feasibility will be reviewed at a high level. Orange County staff members to provide feedback <br /> on critical milestone due dates during feasibility for their staff reporting needs. At kickoff, we will discuss and request <br /> the deliverables needed from Orange County and Town of Hillsborough to conduct the services. These deliverables <br /> include energy usage information for the facilities, construction and/or record drawings (if available), identification of <br /> existing roof warranties and roof manufacturer, and identification of the Authority Having Jurisdiction serving each <br /> facility. <br /> 2) Site Identification/Qualification—Prior to conducting site visits at these facilities,we will identify any known keep-out <br /> or restricted areas for solar panel placement with Orange County and Town of Hillsborough staff. For Orange County, <br /> the general location for solar panel placement on rooftops and placement opportunities for solar parking canopies will <br /> be identified. For the Town of Hillsborough,the general location for solar panel placement on rooftops and placement <br /> opportunities for ground-mounted solar will be identified. The code requirements will be reviewed at a high level to <br /> communicate the rooftop and property setback requirements for solar construction and for the owner to provide any <br /> additional setback needs. <br /> 3) Energy Usage Analysis—The energy usage analysis will consist of reviewing the most recent 12-month kWh(Energy) <br /> and kW(Demand) electricity usage and confirming the rate schedule to qualify the customer's cost per kWh and kW <br /> and to understand any potential rate schedule changes. The maximum solar PV capacity, based on the historical <br /> energy usage for the given account, will be established after the energy usage analysis. Further definition of the <br /> maximum solar capacity will be determined after visiting the site. <br /> 4) Site Visit and Electrical Analysis—Solar site investigation includes: confirming the location for all solar equipment, <br /> identifying the physical point of interconnection for behind the meter application, identifying communications equipment <br /> location, confirming roof-type, assessment of roof condition, identifying setback requirements for existing rooftop <br /> equipment and setbacks for solar panels from roof edge and parapet walls, determining parapet wall heights,verifying <br /> parking canopy and ground-mounted compatibility for the site including underground stormwater/sewer/ utility lines, <br /> confirming property lines,recording switchgear and transformer data,determining site-specific system sizing limitations <br /> based on available real estate or the facilities'existing electrical distribution system and identifying upgrades to existing <br /> electrical system where applicable, and identifying shading concerns from nearby objects. The maximum <br /> recommended solar PV installation capacity will be determined after all relevant site data is obtained. The solar site <br /> Solar . Proposal <br />
