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 \iable based on solar resource availability.
To partially meet its RPS requirement,
WA can purchase solar renewable
energy credits from entire states or a
portion of states as shown in the map
below.
