SREC Knowledge Center

Learn About SRECs

We enable homeowners, businesses, installers and developers to fully realize the value of their solar energy systems by registering their systems to produce solar renewable energy credits (SRECs) and then purchasing these SRECs. We also assist large-scale energy suppliers and utilities in investing in the solar community by managing their state-mandated solar Renewable Portfolio Standard (RPS) requirements and SREC portfolios. Learn more about SRECs and how they can work for you.

RPS and AEPS Defined

A Renewable Portfolio Standard (RPS), or Alternative Energy Portfolio Standard (AEPS), is a state or federal policy that requires electricity suppliers to provide a certain percentage of their electricity from renewable energy resources. More than 30 states have RPS programs, and many of these states have solar RPS requirements that specifically mandate a minimum percentage of energy be produced from solar energy sources. Energy suppliers meet RPS requirements by creating or purchasing SRECs, or by paying a non-compliance fine to state regulatory authorities.
