Bydd y BES yn gymhorthdal yn lle’r refeniw a gollir yn sgil colli’r capasiti ar fysiau i gludo teithwyr oherwydd COVID-19 a’r gofyn i gadw pellter.  Yn ogystal â diwallu angen tymor byr brys, mae’r cytundeb sy’n creu’r BES yn arwydd o gychwyn partneriaeth hir rhwng gweithredwyr a chyrff cyhoeddus fydd yn arwain at ailwampio rhwydwaith bysiau Cymru a chryfhau’r berthynas rhwng dulliau teithio gwahanol trwy, ymysg pethau eraill, docynnau clyfar, uno llwybrau ac amserlenni integredig.
BES will provide an operating subsidy in lieu of lost revenue due to COVID-19 and significantly reduced vehicle passenger carrying capacity due to social distancing. As well as addressing emergency short term needs, the agreement underpinning the BES is intended to signal the beginning of a lasting partnership between operators and public bodies to enable a reshaping of Wales’ bus network, supporting the management and interaction across transport modes including smart ticketing, unified routeing, and integrated timetabling.
