PA HB2223

Requires electric distribution companies to submit evidence evaluating advanced transmission technologies for both existing and proposed transmission infrastructure when filing siting applications with the Pennsylvania Public Utility Commission

Prohibits approval of transmission line applications unless proposed lines incorporate all technically feasible and cost-effective advanced transmission technologies that achieve at least two goals: avoiding new construction, increasing capacity/efficiency/reliability, reducing congestion, or reducing environmental/aesthetic impacts

Defines advanced transmission technologies to include dynamic line rating, advanced power flow controllers, topology optimization software, and high-performance conductors (carbon fiber, composite core, superconductors)

High-performance conductors must have at least 10% lower electrical resistance and at least 75% greater energy carrying capacity compared to standard aluminum-conductor steel-reinforced conductors of similar size

Allows electric distribution companies to recover additional compliance costs through commission-approved tariffs
