Solar PPA for farms & agriculture in Cardiff

Grazing marsh, dairy and the Welsh funding route

South of the city the Wentloog and Rumney Levels — reclaimed grazing marsh — run out toward Newport, while the Vale of Glamorgan behind Barry and Penarth carries dairy and mixed farming. Livestock and dairy give the stronger solar match: refrigeration, milking plant and washdown pull power straight through daylight, so a funded array offsets bought-in electricity rather than exporting it cheaply. Wales adds its own support layer — the Welsh Government Energy Service and Business Wales loans through the Development Bank of Wales are the usual routes — but a power purchase agreement sidesteps borrowing altogether by leaving ownership with the developer.

• Roof arrays on modern livestock and dairy sheds
• Ground-mount costed on lower-grade levels and field margins
• Connection through National Grid Electricity Distribution, the Welsh DNO
• Aligned with Cardiff's One Planet 2030 net-zero target

The numbers for a Cardiff-area holding

Agricultural systems are unusually elastic — 100kWp on a single dairy unit up to 5MWp across a large estate — and the ground-mount option is why farm PPA tariffs open at the low end of 10–14 p/kWh. Yearly savings stretch from about £8k to £500k, so scale and how much you self-consume decide where you land. Put your own usage into the estimator to see the shape of it.

Local context

Cardiff Bay and the Wentloog Industrial Park anchor the city's agri-logistics, and the council's One Planet Cardiff framework targets net zero by 2030.
