Digarbon Round 2 - The decarbonisation fund for tertiary education in Wales

Welcome to our Digarbon Round 2 website page which carries all the information you need to know about this popular fund.

Mae'r dudalen hon hefyd ar gael yn Gymraeg isod.

Digarbon provides loan funding for further and higher education institutions in Wales to support the implementation of heat decarbonisation, energy efficiency, renewable, and electric vehicle and electric vehicle charging infrastructure measures. 

For this fund £10m has been made available for applications in the 2025/26 financial year. For full details please read our guidance notes.

Funding for the scheme has been provided by Welsh Government to help the public sector meet its ambition to be net zero by 2030, and the national target set by the UK government to achieve net zero greenhouse gas emissions across the UK by 2050. 

At Salix, we’re delighted to work with Welsh Government and Welsh Government Energy Service to deliver the loan funding.

We have attached key documents below and should you have any further questions please email our Wales team at [email protected] 

Digarbon is available to institutions of further and higher education in Wales only. To be eligible, organisations must also be receiving greater than 80% of income from educational activities of which commercial and spin-out enterprises are not included.

A ‘soft’ sector cap will be applied when allocating funding of which 25% of the available funding will be allocated to the Further Education Sector, with 75% allocated to the Higher Education Sector.  These sector caps are ‘soft’ and should there be insufficient successful applications to fully allocate funding to a sector, funding will be allocated to the other sector.

Please read our guidance notes and ensure you are eligible before applying through the online portal. Applicants can be supported by external parties who can provide support in preparation of the application form and supporting documents. However, if an application is submitted by an external party, we reserve the right to withdraw the application.

Please have a look at our application area before preparing your application. You can create an account or log in to your existing account in this area. If you have an issue accessing the portal area, please contact [email protected]

The application portal is where you will upload your application form along with supporting documents. 

In preparation for your application, we recommend establishing several contacts at your organisation to be on hand to be contacted. 

Main contact – this is the individual overseeing the project on a day-to-day basis, responsible for reporting and frequent communication with our team at Salix.

Authorising official – an individual in a position of authority at your organisation who can approve and sign official and legal documentation associated with the project.

Finance contact – an individual in your finance team who will be responsible for the accurate allocation of funding and agreeing the loan amortisation schedule.

These include; 

1. Non-domestic buildings owned by eligible Welsh further and higher education institutions can be included in the application. 
2. Buildings on long-term leases with at least 10 years remaining can be included. 
3. Applicants that have a long-term lease arrangement for a building from another public sector body (e.g. local government) in which the lease contract allows the cost savings through improved energy efficiency to be passed to the eligible public body.

Please note, that buildings under PPI/PFI contracts are only eligible if the energy efficiency savings are passed to the eligible public body applying for the loan. Applicants must be able to evidence that this has been clearly negotiated with the partners to the agreement and has been agreed with Salix prior to submission of the application. Please see our guidance notes for full information.

Croeso i'n tudalen gwefan Digarbon Rownd 2 sy'n cynnwys yr holl wybodaeth sydd ei hangen arnoch chi am y gronfa boblogaidd hon.

Mae’r cynllun newydd hwn yn darparu gyllid benthyciad ar gyfer sefydliadau addysg bellach ac uwch yng Nghymru i gefnogi gweithredu mesurau seilwaith datgarboneiddio gwres, effeithlonrwydd ynni, adnewyddadwy, cherbydau trydan a seilwaith gwefru cerbydau trydan.

Ar gyfer y gronfa hon mae £10m ar gael ar gyfer ceisiadau yn y flwyddyn ariannol 2025/26. Am fanylion llawn darllenwch ein nodiadau canllaw isod.

Mae cyllid ar gyfer y cynllun wedi’i ddarparu gan Lywodraeth Cymru i helpu’r sector cyhoeddus i gyflawni ei uchelgais i fod yn sero net erbyn 2030, a’r targed cenedlaethol a osodwyd gan lywodraeth y DU i gyflawni allyriadau nwyon tŷ gwydr sero net ledled y DU erbyn 2050.

Yn Salix, rydym yn falch iawn o weithio gyda Llywodraeth Cymru a Gwasanaeth Ynni Llywodraeth Cymru i ddarparu cyllid y benthyciad.

Rydym wedi atodi dogfennau allweddol isod ac os oes gennych unrhyw gwestiynau pellach e-bostiwch ein tîm Cymru yn [email protected]  

Fe'ch gwahoddir hefyd i'n gweminarau lle gallwn ateb cwestiynau am y gronfa. Cofrestrwch trwy ein rhan digwyddiadau ar ein gwefan.

Mae Digarbon ar gael i sefydliadau addysg bellach ac uwch yng Nghymru yn unig. I fod yn gymwys, rhaid i sefydliadau hefyd fod yn derbyn mwy nag 80% o incwm o weithgareddau addysgol nad yw mentrau masnachol a deillio ohonynt wedi'u cynnwys.

Bydd cap sector ‘meddal’ yn cael ei gymhwyso wrth ddyrannu cyllid a bydd 25% o’r cyllid sydd ar gael yn cael ei ddyrannu i’r Sector Addysg Bellach, gyda 75% yn cael ei ddyrannu i’r Sector Addysg Uwch.  Mae’r capiau sector hyn yn ‘feddal’ a phe na bai digon o geisiadau llwyddiannus i ddyrannu cyllid yn llawn i sector, caiff cyllid ei ddyrannu i’r sector arall.

Darllenwch ein nodiadau canllaw a sicrhewch eich bod yn gymwys cyn gwneud cais trwy'r porth ar-lein. Gall ymgeiswyr gael eu cefnogi gan bartïon allanol a all roi cymorth i baratoi'r ffurflen gais a'r dogfennau ategol. Fodd bynnag, os cyflwynir cais gan barti allanol, rydym yn cadw'r hawl i dynnu'r cais yn ôl.

Edrychwch ar ein hardal ymgeisio cyn paratoi eich cais. Gallwch greu cyfrif neu fewngofnodi i'ch cyfrif presennol yn yr ardal hon. Os oes gennych broblem yn cyrchu ardal y porth, cysylltwch â [email protected]

Y porth ymgeisio yw lle byddwch chi'n uwchlwytho'ch ffurflen gais ynghyd â dogfennau ategol.

Wrth baratoi ar gyfer eich cais, rydym yn argymell sefydlu sawl cyswllt yn eich sefydliad i fod wrth law i chi gysylltu â nhw. 

Prif gyswllt – dyma’r unigolyn sy’n goruchwylio’r prosiect o ddydd i ddydd, sy’n gyfrifol am adrodd a chyfathrebu cyson gyda’n tîm yn Salix.

Swyddog awdurdodi – unigolyn mewn safle o awdurdod yn eich sefydliad a all gymeradwyo a llofnodi dogfennaeth swyddogol a chyfreithiol sy’n gysylltiedig â’r prosiect.

Cyswllt cyllid – unigolyn yn eich tîm cyllid a fydd yn gyfrifol am ddyrannu cyllid yn gywir a chytuno ar amserlen amorteiddio’r benthyciad.

Mae'r rhain yn cynnwys; 

1. Gellir cynnwys adeiladau annomestig sy'n eiddo i sefydliadau addysg bellach ac uwch cymwys yng Nghymru yn y cais. 
2. Gellir cynnwys adeiladau ar brydlesi hirdymor gydag o leiaf 10 mlynedd yn weddill. 
3. Ymgeiswyr sydd â threfniant les hirdymor ar gyfer adeilad gan gorff sector cyhoeddus arall (e.e. llywodraeth leol) lle mae’r contract les yn caniatáu i’r arbedion cost drwy wella effeithlonrwydd ynni gael eu trosglwyddo i’r corff cyhoeddus cymwys.

Sylwch, dim ond os caiff yr arbedion effeithlonrwydd ynni eu trosglwyddo i'r corff cyhoeddus cymwys sy'n gwneud cais am y benthyciad y mae adeiladau o dan gontractau PPI/PFI yn gymwys. Rhaid i ymgeiswyr allu dangos tystiolaeth bod hyn wedi'i drafod yn glir gyda'r partneriaid i'r cytundeb a'i fod wedi'i gytuno gyda Salix cyn cyflwyno'r cais. Gweler ein nodiadau canllaw am wybodaeth lawn.

Fe welwch mai Digarbon Rownd 2 Nodiadau Canllaw yw'r ddogfen fwyaf defnyddiol i'ch helpu i lywio'r cynllun.

Mae ein tîm arbenigol hefyd yn hapus i ateb eich cwestiynau am Digarbon a siarad â chi drwy'r gronfa. Cysylltwch â’r tîm yn [email protected] ac edrychwn ymlaen at eich gweld yn ein gweminarau.
