Major Solar Projects List
Last Updated: May 2023
The Major Solar Projects List is a database of all ground-mounted solar projects, 1 MW and above, that are either operating, under construction or under development. The list is for informational purposes only, reflecting projects and completed milestones in the public domain. The information in the 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 projects under development. This list may be missing smaller projects that are not publicly announced.
Note: SEIA reports project capacity figures in AC units when available.
SEIA Member Benefit:
SEIA makes major solar project data available to the public through the map below. SEIA members have exclusive access to the list as a sortable, searchable MS Excel file that is updated monthly. This version contains additional, valuable information that is not included in the map below, such as the owner, electricity purchaser, land type and expected online date. SEIA Members can access the searchable database here. A full list of the data provided in the members-only version of the list can be found here.

- There are more than 6,200 major solar projects currently in the database, representing nearly 197 GWdc of capacity.
- There are more than 740 major energy storage projects currently in the database, representing more than 10,580 MWh of capacity.
- The list shows that there are more than 96 GWdc of major solar projects currently operating.
- There remains an enormous amount of capacity in the pipeline, with more than 99 GWdc of large-scale solar projects either under construction or under development.

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 canceled.
SEIA actively promotes public policy that minimizes regulatory uncertainty and encourages the accelerated deployment of utility-scale solar power.
