Generator Interconnection Programmatic Environmental Impact Statement

TVA Power Service Area

On July 14, 2026, the Tennessee Valley Authority (TVA) issued a Notice of Intent to prepare a 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 will establish 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 will provide guidance to streamline environmental reviews associated with interconnection-driven transmission activities and help supply the region with reliable, affordable electricity to meet growing demand.
