The bill amends the "Affordable Clean Energy Security Act" to enhance regional energy planning and procurement in Rhode Island. It introduces new sections that allow for the reliable transmission of large- or small-scale domestic energy resources and establishes a framework for state and regional energy procurement. The bill specifically excludes nuclear power from the office of energy resources and the division of public utilities' participation in energy procurement and project approvals, focusing instead on large-scale hydroelectric power and eligible renewable energy resources.

Additionally, the bill outlines the responsibilities of the public utilities commission, which will review and approve commercially reasonable proposals that align with the chapter's objectives, including long-term contracts for energy resources and infrastructure. The commission is tasked with ensuring that these proposals meet environmental and economic standards while emphasizing public input and advisory opinions from relevant state agencies. Furthermore, the bill establishes a commission to determine the public interest of regional energy infrastructure projects, requiring written determinations within ten business days. The act will take effect immediately upon passage.
