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. .
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. .
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. The California Energy Commission (CEC) has given the green light to the Darden Clean Energy Project (DCEP), now officially the largest battery energy storage system in the world once completed joining a list of massive BESS projects being constructed around the world.
