What projects do we include in our database?
We want to be able to cover all utility-scale projects, which is now defined as 4MWac+, so our database includes projects of 3.5MWac (because capacities are often rounded to the nearest whole number) and over. We believe it is very comprehensive for projects over 10MW, but it may be incomplete for smaller projects in some markets.
We also include a few smaller projects, at our discretion, where these are noteworthy or appear on the site maps (see below).
We include all photovoltaic power plant, including concentrating photovoltaics (CPV). Thermal concentrated solar power (CSP) and other solar thermal applications are not shown except where these might appear on the site maps (see below).
Projects in development
Except for those maps which only show commissioned installations, plants are included if they are operating, under construction, decommissioned or planned, in which case they may be included at our discretion if the project has achieved at least one of the following:
- planning consent;
- approval for a support program;
- financial close;
- a power purchase agreement; or
- a grid connection offer.
What is the basis of our analysis?
Statistics, tables and rankings
... whether of worldwide data or by region or by company:
These analyses only include projects:
- above a capacity threshold normally of 4MWac, unless specified otherwise in the accompanying data
- which were delivering power at the reporting date; so
- all projects still in development are excluded, or analysed separately.
