Smart Solar Permitting Platform established; residential solar energy systems; work group; report. Creates the Smart Solar Permitting Platform (the Platform) to serve as a tool for (i) contractors to obtain permits for the construction of streamline-eligible residential solar energy systems and (ii) localities to process applications for such permits. The bill requires the Department of Energy to establish, launch, and administer the Platform by July 1, 2027, as an internet-based platform that automates plan review and instantly releases a permit or a permit revision to construct certain residential solar energy systems that comply with any applicable building codes and state laws. The bill requires localities to allow contractors to submit an application to construct a residential solar energy system through the Platform or through an alternative automated solar permitting platform by July 1, 2028. The bill requires any locality that chooses to use an alternative automated solar permitting platform to submit an annual report to the Department no later than March 1 of each year. The bill directs the Director of the Department to convene a work group to determine the appropriateness of adding a surcharge to local government permitting fees to defray state costs for the Platform and to report its findings to the General Assembly on or before November 1, 2026. This bill is identical to HB 590.
