Subject to subsections (a) and (c) of this section, an electricity supplier shall meet the solar requirement by obtaining the equivalent amount of renewable energy credits from solar energy systems no larger than 15MW in capacity located within the District or in locations served by a distribution feeder serving the District; provided, that renewable energy credits from solar energy systems larger than 15MW in capacity located on property owned by the District, or by any agency or independent authority of the District, may be used to meet the solar requirement.

As of January 1, 2015, notwithstanding paragraph (1) of this subsection, an electricity supplier may meet the remaining non-solar tier one renewable source requirement of the renewable energy portfolio standard by obtaining the equivalent amount of renewable energy credits from solar energy systems that do not satisfy the requirements under paragraph (1) of this subsection.
