Energy (Energy Resilience)

HB 3530, the "Battery and Grid Resilience Act," requires Missouri utilities to create residential programs enabling homeowners to install battery storage systems (minimum 10 kW capacity) connected to the grid. Utilities must offer a $500/kWh upfront rebate (capped at 30 kWh per home) plus performance payments for grid services, with systems required to participate in utility-approved tariffs for five years. The bill includes consumer protections like a 3-day cancellation window, mandatory disclosure of terms and incentives, and requirements for system safety and insurance. Costs for these programs are recoverable through utility rates, with safeguards ensuring low-income customers aren’t unduly burdened and savings are verified.

This bill exempts small, portable solar devices (under 1,200 watts that plug into standard outlets) from most public utility regulations. It requires electricity providers to offer net metering for these devices, allowing homeowners to receive credits for excess energy sent back to the grid, with credits applied to future bills and expiring after 12 months. The law specifically targets moveable units certified by safety labs like UL, not fixed rooftop systems. It does not change existing rules for larger solar installations or utility-scale projects.
