Connecticut mandates electric companies submit energy infrastructure transition plans by December 2025

On April 10, 2025, the Connecticut State Legislature introduced Senate Bill 1560, a significant legislative proposal aimed at enhancing the state's energy infrastructure and promoting the electrification of heating and cooling systems. The bill seeks to address the growing demand for sustainable energy solutions by mandating electric distribution companies to develop comprehensive energy infrastructure transition plans.

The primary provisions of Senate Bill 1560 require each electric distribution company to submit an energy infrastructure transition plan to the state authority by December 1, 2025, and every three years thereafter. These plans must outline strategies for implementing smart metering programs, upgrading infrastructure, and optimizing load factors. Notably, the bill emphasizes the integration of advanced metering infrastructure, which will facilitate the collection and utilization of hourly electricity usage data. This data will support the adoption of time-of-use electric rates, allowing for more accurate billing and greater consumer engagement.

Key components of the proposed plans include infrastructure upgrades to accommodate increased electric loads from heat pump conversions, battery storage installations, and electric vehicle charging stations. The bill also mandates that electric distribution companies publish detailed hourly usage data and pricing on accessible online platforms, enhancing transparency for consumers.

Debate surrounding Senate Bill 1560 has centered on its potential economic and environmental implications. Proponents argue that the bill will accelerate Connecticut's transition to renewable energy sources, reduce greenhouse gas emissions, and ultimately lower energy costs for consumers. However, some opposition has emerged, primarily from stakeholders concerned about the financial burden of infrastructure upgrades on electric distribution companies and, consequently, on consumers.

Experts suggest that if enacted, Senate Bill 1560 could position Connecticut as a leader in energy innovation, potentially attracting investments in clean technology and creating jobs in the renewable energy sector. The bill's focus on electrification aligns with broader national trends toward sustainable energy practices, indicating a significant shift in how energy is produced and consumed in the state.

As the legislative process unfolds, stakeholders will closely monitor discussions and potential amendments to the bill, which could shape its final form and impact on Connecticut's energy landscape. The next steps will involve committee reviews and public hearings, where further insights and opinions will be gathered before a final vote is scheduled.
