The PV Standard Project Deeds will be used by procuring agencies when preparing a Request for Proposal for an Availability PPP Project. Any derogation from the PV Standard Project Deeds for Availability PPP Projects will only be made with the prior approval of DTF. This is to ensure that consistency of risk allocation and drafting is maintained on Availability PPP Projects (other than for genuine project specific reasons), notwithstanding that the projects are procured by different agencies.
