This bill establishes regulations regarding the costs incurred by public utilities for necessary infrastructure upgrades resulting from qualified construction projects aimed at mitigating damage from natural disasters. It mandates that customers who complete such projects must provide certification from a licensed contractor to the Board of Public Utilities and their respective utility within 90 days of project completion. Failure to do so may result in the customer being liable for the costs incurred by the utility for necessary upgrades.

Furthermore, the bill prohibits public utilities from billing customers for these upgrade costs if the customer has complied with the certification requirement. However, it allows utilities to charge customers for their pro rata share of any increase in the utility's rate base or other recovery mechanisms approved by the board. The costs incurred by the utility for necessary upgrades can be included in the utility's rate base for recovery in rate cases.
