Gila River Indian Community PIMA-Maricopa Irrigation Project Feasibility Study

Water Xience, LLC. assisted in the Canal Energy System (CES) feasibility study focused on canal spanning solar panel system over the Casa Blanca Canal. The feasibility level study was divided into three distinct projects to include the following: 1) An approximate $5 million dollar design and construction budget assuming the project limits start at Old Highway 93 and Straddle Interstate 10 (I-10) west and east along the Casa Blanca Canal alignment. 2) An approximate $10 million dollar design and construction budged project assuming the project limits continue to the east of the project defined in the $5 million dollar project along the Casa Blanca Canal alignment. 3) The third project assumed of analysis of the entire limits of the Casa Blanca Canal about 16 miles, to also include a design and construction budger assuming the project limits continue to the east and west side of the I-10. The feasibility analysis included an assessment of the canal alignment, siting analysis, and elimination of canal reaches that are not economically viable due to distance to power infrastructure connectivity, safety concerns, in-line structure and appurtenances, or other factors. Canal cross section geometry, maintenance and operations were also considered in study assumptions. Based on the determination of feasible solar coverage limits, an energy generation analysis was complete using utility scale solar generation modeling software to estimate solar power generation. Assumptions were made with respect to frame support systems and ancillary features. Cost estimates at a feasibility level including design and construction were developed for the three proposed projects. Connectivity to the GRICUA power distribution system was also evaluated including line capacity, optimal connection locations, limitations in the system, and required upgrades or improvements needed to allow the proposed Canal Energy System power generation to be input into their system. All work was documented in a final Canal Energy System Feasibility Report.
