Our pricing includes prevailing wage and equipment recycling as required to receive the solar on public buildings grant. The starting cost of electricity and value of energy savings were conservatively based off Xcel Energy’s tariff rates for 2024. No electricity bills were provided, so we assumed the site does not have demand charges and is on a small general service rate tariff. The PV system would be on rate code A50 which Xcel will pay $0.14281/kWh to $0.15874/kWh for excess solar production for 2024 depending on the winter vs summer months. Cost per kWh charged by the utility for energy usage will not be affected per the utility company. Cashflow assumes the system is approved for the Solar for Public Buildings grant for 60% of the total project with a maximum grant of $72,000. The Investment tax credit was assumed to be the base 30% ITC which will be received under elective pay rules for non-tax paying entities. All efforts to meet domestic content requirements will be made within contract $ amount specified in attachments should the project be well suited for this designation (i.e., should the additional ITC bonus benefit justify the increased cost of American made materials within our project cost, we will proceed with these components, otherwise we will sacrifice the 10% bonus for cost effectiveness). At the time of submittal, suppliers are either unable to provide documentation needed to claim Domestic Content ITC Bonus with the IRS or the increased cost of equipment exceeds value added for 10% bonus ITC.
