Technical Approach <br />9. Technical Approach <br />Utility is: <br />Before designing systems for an energy savings project, Johnson Melloh Solutions <br />(JMS) performs a detailed analysis of the customer's utility data. Based on the data <br />given, the South Bend Central Fire Station currently receives all their electricity from <br />Indiana Michigan Power under the Large General Service Rate (240). From this rate <br />and the attributes of the fire station's electric usage, kilowatt and kilowatt-hour rates <br />were determined. Without power profiles, JMS does not consider demand savings for <br />non-dispatchable energy sources such as solar PV. Provided with this power profile <br />data, JMS can determine these demand savings and guarantee greater cost savings. <br />Solar is <br />Restrictions <br />After performing a utility analysis, economic, regulatory, and physical restrictions are <br />analyzed. Based on the most recent release regarding net metering by the Indiana <br />Utility Regulatory Committee (IUPC), Indiana Michigan Power has notyet reached their <br />maximum capacity for net metering. When net metering is an option, it makes sense <br />economically to offset up to 100% of the customer's annual energy consumption. In the <br />baseline year, 2018, the fire station consumed 534,325 kWh. For physical restrictions, <br />St. Joseph county GIS maps were referenced to find open, city -owned land parcels <br />suitable for a solar array. No suitable parcels were found, restricting the project to roof <br />mounted arrays. <br />Design <br />Once restrictions are defined, JMS starts designing the solar array on Helioscope, a <br />highly credible and widely used solar PV modelling software. With this software, JMS <br />conservatively accounts for losses and allocates space for mobi-lity and equipment <br />access while placing modules. Module orientation is then optimized for greatest power <br />output and, if given, power profiles. This process gave simulation results as shown <br />below. <br />Solar System <br />Size 132.4 kWdc <br />Annual Production 160,877 kWh <br />Experience <br />JMS's vast portfolio of solar PV projects, as well as our <br />service to these projects throughout their lifetimes <br />has helped us develop knowledge of what products <br />perform best, are most economical, and provide <br />greatest stability in the market. In the design process, <br />these products are vetted by project managers who <br />deal with physical system installations. This ensures <br />that the technologies will perform as stated in energy savings calculations. <br />Innovation <br />Though experience with products helps continue our excellence in performance, JMS <br />recognizes that there are new technologies on the market that may prove useful in <br />current projects. If our experts are not experienced with these products, we do the <br />necessary research and studies. This has been evident through JMS's existence with <br />use of solar PV, solar thermal, and vertical axis wind turbines. <br />Z ,. <br />Page 22 <br />
