RPS (Renewable Portfolio Standard)
A state regulation requiring utilities to source a minimum percentage of electricity from renewable resources by a target date. Also called a Renewable Energy Standard (RES).
Why It Matters
States with aggressive RPS targets tend to have better solar incentives and higher SREC values because utilities need to buy more renewable energy to comply.
Real-World Example
California's RPS requires 60% renewable electricity by 2030 and 100% clean energy by 2045, driving strong solar adoption.
