The Minnesota State Legislature has introduced Senate Bill 2373, aimed at updating inspection fees and regulations related to energy storage and battery systems. Introduced on March 10, 2025, the bill seeks to address the growing demand for energy storage solutions and streamline the inspection process for these systems.

One of the key provisions of the bill includes a structured fee schedule for the installation of energy storage and battery systems, which varies based on the wattage capacity. For instance, installations ranging from zero to 5,000 watts will incur a fee of $60, while those exceeding 5,000,000 watts will face a fee of $3,518, plus additional charges for every 10,000 watts over that threshold. This tiered fee structure is designed to reflect the complexity and scale of the installations, ensuring that inspection costs are proportional to the energy output.

Additionally, the bill proposes adjustments to existing reinspection fees, setting them at $55 for on-site reinspections and $35 for remote virtual reinspections. These changes aim to enhance the efficiency of the inspection process and reduce delays caused by circumstances beyond the inspector's control, which will now incur a supplemental fee of $35 to $55.

The introduction of Senate Bill 2373 has sparked discussions among stakeholders, particularly regarding the implications for the renewable energy sector. Proponents argue that the updated fee structure will encourage the adoption of energy storage technologies, which are crucial for integrating renewable energy sources into the grid. However, some critics express concerns that the increased fees could pose a financial burden on smaller installers and homeowners looking to invest in energy storage solutions.

As the bill progresses through the legislative process, its potential impact on Minnesota's energy landscape remains a focal point of debate. Experts suggest that if passed, Senate Bill 2373 could facilitate a more robust energy storage market, aligning with broader state goals of sustainability and energy independence. The next steps will involve further discussions and potential amendments as lawmakers consider the feedback from various stakeholders.
