Substitute House Bill No. 7017 aims to enhance Connecticut's electric grid by promoting the use of grid-enhancing technologies and advanced conductors. The bill requires electric distribution companies (EDCs) and incumbent transmission owners to submit at least two project alternatives to the Connecticut Siting Council when proposing construction or modifications of transmission lines, substations, or switchyards, particularly for projects estimated to cost $5 million or more. One alternative must utilize advanced conductors, while the other must incorporate grid-enhancing technologies (GETs) or nontransmission alternatives. Additionally, EDCs are mandated to file annual reports with the Public Utilities Regulatory Authority (PURA) detailing planned projects and modifications, starting January 15, 2026.

The bill also expands the authority of the Department of Energy and Environmental Protection (DEEP), PURA, and the Office of Consumer Counsel (OCC) to retain consultants without inter-agency consultation, allowing them to seek expert assistance for proceedings with federal agencies. It stipulates that PURA must prioritize project proposals that utilize GETs or nontransmission alternatives if they are cost-effective. Furthermore, the bill introduces new requirements for EDCs to analyze the cost-effectiveness and timelines for deploying grid-enhancing technologies, while capping consultant expenses at $2.5 million per year. The effective date for these provisions is set for October 1, 2025.
