Requires electric and gas public utilities to establish "Energy Bill Watch" program and include certain information in bills and notices to customers.

New Jersey's S 3620 requires electric and gas utilities using smart meters to establish an "Energy Bill Watch" program for smart meter customers. The program mandates utilities to notify customers when their daily usage exceeds the previous billing cycle's average (on the 10th and 20th days of each cycle), offer customizable dollar-value alerts, and include average monthly usage costs and kilowatt/therm amounts in notifications. Utilities must automatically enroll smart meter customers, provide opt-out options, advertise the program through multiple channels, and include specific billing details in all customer bills (previous cycle amount, current cycle amount, and the difference between them). This bill directly affects smart meter customers of New Jersey's electric and gas utilities.
