Leading utility-scale solar power project developers

The most recently published list of the top-ranked utility-scale solar project developers is shown below. Maps are available for many of these companies using the Developer pull-down menu above.

This shows  the position in early 2020, as further detailed in this release.

What is a project developer?

The project developer typically initiates new solar power projects and owns them during at least the early stages of development. This would usually include site selection, including negotiations with the landowner, and the initial designerating station.

The developer will usually handle the consenting process both for planning approval and grid connection, and often also appoints the EPC contractor and identifies the preferred power off-taker.

Some project developers retain ownership of projects they have developed, but many will sell them on to a new owner before, during or after construction.

Where the developer retains the project during the construction phase, it will normally seek to finance part of the cost through non-equity finance.

Basis of the data used

The data used for the analysis and the table on the left is derived from operating projects of 4MWAC+ on the Wiki-Solar Database, according to these criteria.

Project developers are identified against 28% of the operating capacity on the Wiki-Solar Database (of which these top 25 account for 25%). The total capacity for developers listed may therefore be on average up to four times that identified here (though many do confirm details of their portfolio to Wiki-Solar).

Because capacity is included in these figures only when the plant is connected, the total capacity now developed by many of those listed will be higher.

Some developers in this list also fulfil other roles in utility-scale projects. The figures quoted here apply only to their project development activities. Where companies have maps, however, these will show all their projects.

How to get listed

Wiki-Solar's participant lists are all compiled consistently from its Database of utility-scale solar projects. If your company should be (higher) of the list, go to this page for further details.

Remember these figures are based solely on the output (AC) capacity of operational projects over 4MWac.
