California assesses pilot project testing solar canopies over irrigation canals
Hacker News reports that state officials and local partners are evaluating a canal-shading solar experiment in Turlock.
The short version
- Project Nexus, a partnership including the Turlock Irrigation District and California water officials, is testing solar panels installed over canal sections to generate electricity and curb evaporation.[Hacker News]
- The 1.7-megawatt pilot was funded by a $20 million state grant covering both infrastructure and research.[Hacker News]
- Other water districts face practical constraints, with Contra Costa County planning to pipe canals instead due to tight maintenance space.[Hacker News]
- State water officials are withholding further investments until a final research report evaluates the pilot's performance.[Hacker News]
Key facts
- Jordan Harris and Robin Raj founded Solar Aquagrid and partnered with the Turlock Irrigation District, UC Merced, and the California Department of Water Resources on Project Nexus.[Hacker News]
- A $20 million state grant funded both the research and infrastructure for the Project Nexus proof-of-concept installation.[Hacker News]
- Project Nexus generates 1.7 megawatts of electricity over small sections of Turlock canals.[Hacker News]
- UC Davis researchers estimate California's overall water supply could decrease by up to 25% by 2050 due to rising temperatures.[Hacker News]
- Contra Costa County Water District determined canal solar panels are unrealistic for their system due to limited maintenance space, opting instead for pipeline conversion.[Hacker News]
What remains uncertain
- Whether the state will invest in additional solar canal installations remains pending review of the pilot's final report.[Hacker News]
