DOE/EA-2178: Draft Environmental Assessment

Weld Solar Project; Weld County, CO

This draft EA evaluates the environmental impacts of the Weld Solar's request for an interconnection of the Project to the WAPA transmission system at the Ault Substation. The proposed Project’s (150-megawatt (MW) nameplate capacity solar photovoltaic (PV) facility and a 100-MW battery energy storage system (BESS) with a storage duration of 4 hours (the Weld Solar Project [Project]) on approximately 1,028 acres of private land and 472 acres of state land approximately 4 miles northwest of Ault in Weld County, Colorado) generation tie-in (gen-tie) line would interconnect with Western Area Power Administration’s (WAPA’s) adjacent Ault Substation.
