Defnyddir trefniadau’r Gronfa Buddsoddi i Arbed i ddyrannu’r cyllid hwn am fod y Gronfa yn ffordd syml ac ymatebol o ddarparu cyllid.  Oherwydd ei allu i fuddsoddi mwy, ei gyrhaeddiad daearyddol a sectoraidd, ac am ei bod yn cyd-fynd â’r Rhaglen Effeithlonrwydd ac Arloesedd, gall y Gronfa Buddsoddi i Arbed ddyrannu’r cyllid ychwanegol yn gyflym ac mewn ffordd strategol.  Mae wedi’i phrofi’i hun yn ffordd o ddyrannu cyllid i ystod eang o brosiectau, ac wedi datblygu trefniadau ar gyfer monitro a gwerthuso canlyniadau prosiectau.
The Invest-to-Save Fund arrangements will be used as the vehicle for allocating this funding as it offers a simple and responsive means by which funding can be provided.  Invest-to-Save can allocate the additional funding promptly and strategically - given its ability to make larger scale investments, its geographical and sectoral reach and its alignment to the Efficiency and Innovation Programme.  It has a proven track record of allocating funding to a broad range of projects and has developed arrangements for monitoring and evaluating project outcomes.
