An Act amending Title 66 (Public Utilities) of the Pennsylvania Consolidated Statutes, in rates and distribution systems, further providing for voluntary changes in rates.

HB 320 amends Pennsylvania's public utility law to strengthen notice requirements for rate changes. It requires utilities to provide 60 days' advance notice to the Public Utility Commission and customers about proposed rate changes, using plain language in all customer communications. The bill mandates that rate change notices must clearly highlight the change on mail envelopes or exteriors, and all changes must be filed as new or updated tariffs. This directly affects utility companies (like gas, electric, and water providers) and their customers by increasing transparency around billing adjustments. The law takes effect 60 days after enactment.
