PV Policy Driven and Utility Scale PV
 Site Characteristics
 Resource availability:
   • PV policy driven: State has a RPS that promotes
    solar development; no sites are excluded based
    on resource availability
   • Utility scale PV: Direct nonnal solar resource
    availability equal to or greater than 5 kWh/m2/day
 Distance to transmission lines of 10 miles or less
 Property size of 40 acres or more
 Distance to graded roads of 25 miles or less

                                                  A state renewable portfolio standard (RPS) that includes a solar set-aside requires a percentage of the state's
                                                  electricity be generated from solar resources. An RPS can also include a solar multiplier that gives additional
                                                  credit in meeting the RPS for solar projects or require an increase in distributed generation (i.e., electricity
                                                  generation close to the point of use), which can spur solar development. Policy driven demand for electricity
                                                  generated from solar resources may increase the viability of PV solar generation at a site that would otherwise
                                                  not be considered \iable based on solar resource availability.
