Energy (Energy Storage)

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.

SB 838 modifies Missouri's renewable energy standard by establishing phased requirements for electric utilities: 2% renewable energy by 2013, increasing to 5% by 2017, 10% by 2020, and 7.5% annually starting in 2021. At least 2% of each utility's requirement must come from solar energy. The bill also creates an "accelerated renewable buyer" program for large commercial customers (over 80 average megawatts) that contract directly for renewable energy, allowing them to exclude that energy from utility compliance calculations and receive exemptions from renewable energy compliance costs. These changes directly affect Missouri's electric utilities and qualifying large commercial energy buyers.

HB 1731 creates a state-regulated rebate program for homeowners and businesses installing solar energy systems paired with energy storage. It requires electrical corporations to offer per-watt rebates (ranging from $2.00 to $0.25 per watt) based on installation dates between 2026 and 2032, with decreasing amounts over time. To qualify, customers must install a "smart inverter" (safety-compliant solar inverter), add energy storage, and transfer renewable energy credits for 10 years. The bill caps annual and total rebate costs for utilities based on their customer size (e.g., large utilities capped at $5.6 million annually) and allows utilities to recover rebate costs through rate adjustments.

SB 953 creates a "Natural Resources Protection Fund" to manage environmental fees, including a new "Missouri Air Emission Reduction Fund" for emissions inspection fees. It changes rules so unspent funds won’t revert to general revenue after 2027 (previously they did), and requires 5% of electric power tax revenue to fund air pollution programs. The Department of Natural Resources will use these funds for environmental programs, while emissions inspection stations must collect and remit fees to the state treasurer. The bill directly affects state environmental agencies, inspection stations, and public programs focused on air/water quality.
