Quick Facts on State 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.

                    This mapvjas developed by SRA International for the U.S. Environmental Protection Agency (EPA) OSWER Center for Program Analysis. Results are
                    based on site screening criteria adapted from National Renevjable Energy Laboratory (NREL) criteria. CIS data provided by NREL and EPA and policy
                    data provided by the Database of Sfafe Incentives for Renevjables $ 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 the accompanying Data Guidelines document at
