The proposed Chuckwalla Solar Projects would be the sixth utility-scale PV solar project on the Reservation to be recently evaluated in an EIS. The previously evaluated solar projects on the Reservation include:

• K Road Moapa Solar Facility (K Road) - 350 MW PV solar project, Final EIS published in 2012, west of the Chuckwalla Solar Projects, constructed and operating (BIA 2012)
• Moapa Solar Energy Center (MSEC) - 200 MW PV solar project, Final EIS published in 2014, west of the Chuckwalla Solar Projects, approved but not constructed (BIA 2014a)
• Aiya Solar Project (Aiya) - 100 MW PV solar project, Final EIS published in 2016, north of the Chuckwalla Solar Projects, approved but not constructed (BIA 2016)
• Eagle Shadow Mountain Solar Project (ESMSP) – 300 MW PV solar project, Final EIS published in 2019, west of the Chuckwalla Solar Projects, currently under construction (BIA 2019)
• Arrow Canyon Solar Project (ACSP) – an expansion of the solar field of the approved MSEC solar project, Final SEIS published in 2020, north of the Chuckwalla Solar Projects approved but not constructed (BIA 2020)
• Southern Bighorn Solar Projects (SBSP) – two PV solar projects with a combined capacity of 400 MWs, Draft EIS published in 2021, west of the Chuckwalla Solar Projects, currently in the NEPA process (BIA 2021)

While the solar site and gen-tie associated with the proposed Chuckwalla Solar Projects would occupy a different footprint than the previously evaluated PV solar projects on the Reservation, the previously analyzed facilities, location, and many of the resources/uses evaluated would be similar to Chuckwalla Solar Projects. Analyses from the previous resource investigations are incorporated by reference in the Chuckwalla Solar Projects EIS, where applicable.
