Generator Interconnection Programmatic Environmental Impact Statement

TVA Power Service Area

October 2026 – The Tennessee Valley Authority (TVA) issued a draft programmatic environmental impact statement (PEIS) to evaluate the potential effects of transmission system activities associated with generator interconnection requests across TVA’s Power Service Area (PSA).

The PEIS establishes a programmatic, bounded framework to support efficient, consistent, and predictable National Environmental Policy Act (NEPA) review for generator interconnection-related transmission actions conducted under TVA’s Large Generator Interconnection Procedures (LGIP), Small Generator Interconnection Procedures (SGIP), and Expedited Resource Addition Study (ERAS). The PEIS will also support tiered, site-specific reviews where needed.

This framework provides guidance to streamline environmental reviews associated with interconnection-driven transmission activities and help supply the region with reliable, affordable electricity to meet growing demand.

Public Involvement 

TVA released a Notice of Intent in the Federal Register inviting the public to submit comments on the scope of the PEIS. Comments were due by August 14, 2026. TVA received comments from NPS and EPA and will be outlined in the draft EIS.

The draft PEIS 30-day comment period will end on November 19, 2026.

All comments received, including names and addresses, will be part of the public administrative record. Comments will be considered in the final PEIS. Please submit comments here.
