SR Mount Pleasant Solar Facility
Marshall County, Mississippi
November 2026
The Tennessee Valley Authority (TVA) requests public comments on the draft environmental assessment (EA) for the construction, operation, and maintenance of the proposed Silicon Ranch (SR) Mount Pleasant solar facility in Marshall County, Mississippi. The solar facility would be constructed, owned, and operated by SR Mount Pleasant, LLC. TVA is evaluating the potential purchase of electric power that would be generated from the proposed SR Mount Pleasant solar facility. Please submit comments by November 23, 2026. See below for information on how to submit comments.
The SR Mount Pleasant solar facility would occupy about 343 acres of a 1,194-acre Project site located about 2 miles west of Mount Pleasant in Marshall County. The solar facility would have a generating capacity of up to 50 megawatts (MW) alternating current (AC) and a potential 50-MW AC/200-MW-hour (MWh) battery energy storage system (BESS. The solar facility would connect to TVA's existing adjacent Holly Springs–Chickasaw Trails 161-kilovolt transmission line (L5861) via a new on-site Project substation. TVA would replace (reconductor) the existing overhead ground wire (OHGW) with optical ground wire (OPGW) along an approximately 2-mile portion of L5861. TVA would also construct about 2 miles of new OPGW pole line within a newly acquired 25-foot-wide right-of-way (ROW) easement adjacent to the existing L5861 alignment.
This EA evaluates the effects of the proposed action and alternatives on the human environment in compliance with the National Environmental Policy Act (NEPA) and also addresses specific requirements associated with a number of other federal laws and regulations, such as National Historic Preservation Act (NHPA), Endangered Species Act (ESA), Clean Water Act (CWA), and Clean Air Act (CAA), and pertinent executive actions, including Executive Order (EO) 11988 (Floodplains Management), EO 11990 (Protection of Wetlands), EO 13112 as amended by 13751 (Invasive Species), and other applicable or relevant EOs.
TVA will use this EA to support the decision-making process and to determine whether an EIS should be prepared or whether a Finding of No Significant Impact may be issued.
Public Involvement
You may submit comments here, by email to [email protected], or by mail to the contact below. All comments must be submitted no later than November 23, 2026, to be considered. Please note that any comments received, including names and addresses, will become part of the project administrative record and will be available for public inspection.
This project has been identified as having the potential for proposed floodplain and/or wetland impacts as described in the relevant sections of the Draft EA. To comply with the floodplain and wetland executive orders, TVA is also seeking public comment on the avoidance or minimization of potentially adverse floodplain or wetland impacts for the proposed actions described in the NEPA document.
