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 normal solar resource
availability equal to or greater than 5 kWh/nr/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
Number of sites
40 to 100 acres: 7 sites
100 to 200 acres: 8 sites
Greater than 200 acres: 23 sites
Total: 38 sites; 65,107 acres
Quick Facts on State Solar Energy Policy as of December 2009
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 viable based on solar resource availability.
To partially meet its RPS requirement,
AZ can purchase solar renewable
energy credits from entire states or a
portion of states as shown in the map
below.

This map was developed by SRA International for the U.S. Environmental Protection Agency (EPA)
OS WER Center for Program Analysis. Results are based on site screening criteria adapted from
National Renev&ble Energy Laboratory (NREL) criteria. GIS data provided by NREL and EPA and policy
data provided by the Database of State Incentives for Renevjables S Efficiency (DSIRE). This map and
its associated data are intended to provide a general understanding of the renev&ble energy potential of
EPA tracked sites: additional site-specific technical and economic analysis is required to
determine the actual energy generation potential of these sites. For further information, please see
