This bill amends the Alternative Energy Portfolio Standards Act of November 30, 2004, specifically updating the definitions of "alternative energy sources" and "tier I alternative energy source." The new legal language introduces the concept of "linear generators" as a recognized alternative energy source. Linear generators are defined as integrated systems that convert linear motion into electricity without combustion, are capable of varying power output, and can utilize multiple fuel types, including renewable options like hydrogen, ammonia, and biogas.

Additionally, the bill specifies that energy derived from linear generators will be classified as a "tier I alternative energy source." These amendments aim to expand the scope of renewable energy sources recognized under Pennsylvania law, promoting the use of innovative technologies in the state's energy portfolio. The act is set to take effect 60 days after its passage.
