Both public and private actors can establish such platforms (they typically also provide part of the financing), with the legal form and the financing structure to be determined depending on the projects' needs and the main investors' interests (managed account, co-investment agreement, Special Purpose Vehicle, etc.).
Selliseid platvorme vivad luua nii avalik-igusliku kui ka erasektori esindajad (nad rahastavad tavaliselt ka osa projekti maksumusest), platvormi iguslik vorm ja rahastamisstruktuur mratakse kindlaks projekti vajadustest ja peainvestori huvidest lhtuvalt (hallatav konto, kaasinvesteerimisleping, eriotstarbeline rahastamisvahend jne).
