About the Major Solar Projects List:

This list is for informational purposes only, reflecting projects and completed milestones in the public domain. The information in this list was gathered from public announcements of solar projects in the form of company press releases, news releases, and, in some cases, conversations with individual developers. It is not a comprehensive list of all utility-scale solar projects under development. This list may be missing smaller projects that are not publicly announced. Particularly, some smaller projects located outside of California that were built on a short time-scale may be missing from this list.
This list includes ground-mounted utility-scale solar power plants larger than 1 MW that directly feed into the transmission grid. This list does not include large "behind the meter" projects that only serve on-site load. One exception to this is large projects on military bases that only serve the base.
SEIA does not guarantee that every identified project will be built. Like any other industry, market conditions may impact project economics and timelines. SEIA will remove a project if it is publicly announced that it has been cancelled.
SEIA actively promotes public policy that minimizes regulatory uncertainty and encourages the accelerated deployment of utility-scale solar power.
