Establishes certain requirements for public utility rate increases.

S 2151 requires public utilities in New Jersey to notify affected customers about proposed rate increases through bill inserts or local newspaper ads. The notice must include a summary of the filing, the reason for it, and its impact on customers. After the Board of Public Utilities makes a final decision, utilities must send a plain-language summary of that decision to customers 30 days before new rates take effect (if approved) or within 14 days (if denied). The bill also mandates that the Board respond in writing to public questions submitted during rate hearing within 14 days. This bill directly affects utilities and their customers by increasing transparency around rate change processes.
