Solar PPA for factories & manufacturing in Cardiff

Wentloog and Cardiff's eastern industrial parks

Cardiff gathers its larger manufacturing and distribution sites to the east of the city at Wentloog Industrial Park and Cardiff Industrial Park, with further commercial premises around Cardiff Bay and Atlantic Wharf. These broad, low-rise footprints are natural hosts for rooftop generation, and a solar PPA lets a Cardiff factory take that generation without funding, owning or maintaining the system itself — the developer handles all of it.

Why factories suit the model

A manufacturing site draws its heaviest power during the working day, which is when a roof array is producing, so self-consumption stays high and little is exported. That alignment is why factories return more from on-site solar than most sectors. Under a PPA the occupier buys output at a fixed unit price of 10–14p; with systems typically between 250kWp and 2MWp and a local commercial bill near £45,000, larger plants see yearly savings land in the £35k–£280k bracket. Weigh a PPA against buying the system outright on our finance options comparison.

Welsh policy and grid

Cardiff pursues net zero by 2030 under its One Planet Cardiff plan, and Welsh firms can draw on the Welsh Government Energy Service and Business Wales loans through the Development Bank of Wales. South Wales connects via National Grid Electricity Distribution, so early engagement on capacity helps — a consideration shared by sites in Newport, Barry and Caerphilly.

• Nothing to buy and nothing to maintain
• A contracted rate insulated from wholesale swings
