Requires BPU to prohibit electric and gas public utilities from charging residential customers certain types of payments based on certain billing practices.

S 2711 requires New Jersey's Board of Public Utilities (BPU) to prohibit electric and gas utilities from charging residential customers lump-sum payments when actual usage exceeds estimated usage under equal payment plans. It also bans utilities from "underbilling" residential customers - charging them for the difference between estimated and actual usage after the fact - and prevents adding those unpaid balances to future bills. The bill mandates that any annual adjustments to equal payment plans must be based solely on a customer’s actual usage data, not estimates. This directly affects residential electricity and gas customers in New Jersey by preventing unexpected large charges tied to billing practices.
