Ystradgynlais SA9 sits on the administrative boundary between Neath Port Talbot and Powys, and that boundary crossing has practical consequences for commercial solar procurement that our first Ystradgynlais guide introduces. This guide goes deeper on two specific aspects: the DNO boundary that runs through the SA9 catchment, and the distinction between procurement routes available to Powys County Council as public-sector landlord versus Ynni Cymru routes available to tenant businesses on the same estate.
The NGED and SP Manweb boundary at SA9
Ystradgynlais town centre and Ynyscedwyn Industrial Estate are served by NGED. Communities to the north — Abercraf and the upper Tawe Valley — transition toward the SP Manweb network that covers most of Powys. For commercial systems in Ynyscedwyn, the relevant DNO is NGED. G99 Type A approval timelines currently run at 10 to 14 weeks. FLD runs a NGED pre-application feasibility check before committing to full G99 submission for all SA9 systems above 100 kWp.
Powys County Council as landlord: Salix Wales route
Ynyscedwyn Industrial Estate is owned by Powys County Council — a public-sector landlord relationship that opens the Salix Wales interest-free loan programme. Powys CC borrows at 0% interest to fund solar on estate buildings, and repays from energy savings or a green lease solar service charge from tenants. A 75 kWp Ynyscedwyn rooftop at 945 kWh/kWp generates 70,875 kWh annually. At 72% self-consumption, year-one benefit approximately £15,800. Salix repayment on £65,000 at a 7-year term: £9,300 per year. Net benefit from year one: approximately £6,500.
Ynni Cymru for tenant-owned premises
Tenant businesses at Ynyscedwyn who own their freehold premises access Ynni Cymru capital grants on the standard basis. For a tenant-owned 50 kWp to 100 kWp rooftop in SA9, grants of £10,000 to £25,000 are realistic. FLD establishes tenure status at initial enquiry and routes the client to the appropriate programme.
Farming Connect for the agricultural fringe
Upper SA9 farm businesses at Abercraf and Coelbren access Farming Connect grants for agricultural solar. Farming Connect and Ynni Cymru are separate programmes with separate eligibility. A farm diversification business running agri-tourism at the same holding may access both programmes for different buildings.
