Proposed Bill No. 6290 aims to amend the general statutes concerning the Renewable Portfolio Standard and the oversight of the Public Utilities Regulatory Authority (PURA). Key provisions of the bill include redefining "class I renewable energy source" to encompass nuclear and hydropower energy sources, thereby broadening the scope of renewable energy classifications. Additionally, the bill seeks to enhance oversight of PURA, mandate an audit of the Combined Public Benefits Charge and its associated programs, and enforce functional and operational separation of unregulated or underregulated affiliates of public utilities.

Furthermore, the bill proposes to impose revenue transfer caps, require a line-item audit of large electricity generation facilities, and conduct a comprehensive study on the viability of the state's electric grid. These changes are intended to improve regulatory oversight and ensure the integrity and efficiency of the state's energy infrastructure. The bill reflects a significant shift in energy policy by recognizing nuclear and hydropower as renewable sources and aims to strengthen the regulatory framework governing public utilities.
