Yn yr un modd â'r buddsoddiad cyntaf, bydd yr ail fuddsoddiad, Band B, yn cael ei ariannu ar y cyd gan Lywodraeth Cymru, Awdurdodau Lleol a phartneriaid eraill. Bydd y rhan fwyaf o'r Rhaglen yn cael ei hariannu o gyllidebau cyfalaf. Fodd bynnag, yn wahanol i don gyntaf y Rhaglen, bydd ymgais yn y don nesaf i gynnwys buddsoddiad ychwanegol sydd â gwerth cyfalaf o tua £500m a ariennir drwy'r Model Buddsoddi Cydfuddiannol.
As with the first tranche of investment, the second tranche, Band B, will be jointly funded between the Welsh Government, Local Authorities and others.  The bulk of the Programme will be funded from capital budgets. However, in contrast to the first wave of the Programme, this next wave will seek to include additional investment with a capital value of around £500m funded through the Mutual Investment Model.
