Energy (Solar)

This bill establishes a new program for community renewable energy systems, allowing multiple subscribers to share access to solar or wind energy projects through a shared subscription model. The Public Utilities Regulatory Authority must create rules by December 2026 that enable any electricity customer to subscribe to these systems while receiving lower electricity costs than standard service rates. Key provisions include a cap on renewable energy credits at 200% of a subscriber's typical annual usage and a host bank system to manage and monetize any excess energy not directly subscribed to. The program requires at least two subscribers per system and prohibits any single subscriber from owning more than 60% of the total subscriptions.

This bill updates Connecticut's property tax exemption rules for renewable energy systems, expanding eligibility for homeowners, farms, and businesses while clarifying how exemptions are calculated. It allows property tax exemptions for residential solar, wind, and geothermal systems installed on or after October 1, 2007, and extends similar benefits to commercial and industrial renewable energy projects installed between 2010 and 2013 in specific municipalities. The legislation also establishes new exemption categories for commercial solar and wind projects installed after 2014, with additional restrictions taking effect in 2025 and 2026 that limit exemptions to the equipment itself rather than the entire property value. These changes apply to Class I renewable energy sources including solar, wind, geothermal, and hydropower facilities that generate electricity for on-site use.

This bill establishes a pilot program to test solar-powered noise barriers along state highways, aiming to reduce traffic noise while generating electricity. It requires the state transportation commissioner to install and evaluate one to three of these structures, consulting with utility regulators on power connections, and submit a detailed report by January 2028 on costs, performance, and environmental impacts. The legislation also updates vehicle noise regulations by reinforcing requirements for mufflers, exhaust systems, and horns, while increasing the fine for violations to $150,000 per offense. These changes directly affect state highway infrastructure projects and motor vehicle owners and operators.

SB 233 modifies exemptions for solar energy work under state law, specifically adding new provisions to exempt certain solar installation activities from licensing requirements. The bill creates an exemption (point 17) allowing solar contractors to perform work like hoisting solar panels, mounting racking systems, and installing ground supports for large solar facilities (over 25 megawatts) without full licensing. This directly affects solar contractors and developers of commercial-scale solar projects by simplifying installation processes for specific tasks. The change takes effect October 1, 2026, and does not create new consumer protections but adjusts regulatory scope for solar contractors.

HB 5036 creates a standardized, automated online system (the "smart solar permitting platform") to streamline building permits for residential solar installations under 12 kilowatts. The bill requires Connecticut's Commissioner of Administrative Services to develop or implement this platform by July 2028, enabling instant permit issuance for compliant rooftop solar systems after automated review against building codes. Municipalities must adopt this platform or an equivalent alternative by January 2029, update fee schedules to reflect reduced administrative costs, and submit compliance reports. This directly affects homeowners installing small solar systems and local governments handling solar permitting, reducing approval times from days or weeks to near-instantaneous for eligible projects.

HB 5340 establishes a new program to expand access to residential renewable energy by requiring electric distribution companies to offer tariffs for purchasing energy from small-scale, on-premise renewable systems (under 25 kilowatts). It directly affects low-income residential customers and those in affordable housing developments (defined as households earning ≤60% of area median income or meeting specific housing affordability criteria). The bill mandates the Public Utilities Regulatory Authority to create this program by July 2027, setting rates and terms that consider grid reliability, installation costs, and benefits to both participants and non-participants. The program will allow residential customers to sell excess renewable energy back to utilities under standardized terms for up to 20 years.

SB 320 creates a working group within the Department of Energy and Environmental Protection, required to begin by October 1, 2026. The group will examine delays in building electric transmission lines, costs for grid upgrades needed for new energy projects (like solar), and fair cost-sharing methods for infrastructure improvements. It must submit recommendations to the legislature by July 1, 2027, focusing on state agency coordination, grid planning, and potential policy changes affecting utilities and energy developers. This bill directly affects state agencies, electric distribution companies, and future energy infrastructure decisions.
