This Practice Note provides an overview of the key issues in the development, financing, construction, operation, and decommissioning of a ground-mounted solar project in the UK. It includes some detail around the use of project finance but, unless the project is of a particularly large size, many sponsors are increasingly prepared to finance development and construction from their own balance sheet, rather than seek recourse to the debt markets. This is particularly the case when the original developer has already sold the project ‘pre-construction’ to an investor. This Practice Note also assumes that the ground-mounted solar project is developed as a standalone project, as opposed to a hybrid project in which the solar technology is co-located with a battery energy storage system (BESS) on the same site, or combined with another generation technology. However, co-location is referenced in this Practice Note: • as a potential issue for consideration by the project sponsors at the outset when devising the structure for the project, or after the project has commenced operation, see Sections: Development phase: key
