An Act amending Title 66 (Public Utilities) of the Pennsylvania Consolidated Statutes, in restructuring of electric utility industry, providing for membership in regional transmission organization.

HB 1599 requires Pennsylvania electric distribution companies to join regional electricity grid operators (regional transmission organizations, or RTOs). It mandates that these companies submit annual reports by February 1st detailing all votes they cast or had affiliates cast at RTO meetings during the previous year. The reports must include a 20-100 word explanation of how each vote serves the public interest. The bill takes effect 60 days after enactment, aiming to increase transparency in utility decision-making within regional grid management.
