Solar PPA for retail estate in Cardiff

One Planet Cardiff puts retail roofs in scope

Cardiff's One Planet Cardiff strategy and 2030 net zero pledge bring commercial rooftops squarely into view, and retail premises are among the readiest to act. A store's demand — refrigeration, lighting, heating and point-of-sale — bunches into trading hours, exactly when a rooftop array generates, so most of what the panels make is used in the building rather than sold back to the network.

The Welsh funding picture

Sign a solar PPA and a Cardiff retailer commits no capital: an installer funds and maintains the system and sells its output at a held rate of 12–16 p/kWh, comfortably below grid prices on a bill averaging about £45,000 a year, for a saving that can reach £15,000–£250,000 across several stores. Businesses that would rather own can route instead through the Welsh Government Energy Service or a Development Bank of Wales loan via Business Wales — worth setting side by side.

Distribution and catchment

South Wales connections are managed by National Grid Electricity Distribution. Retail and commercial stock concentrates around Cardiff Bay, Atlantic Wharf, Wentloog Industrial Park and Cardiff Industrial Park, with a shopper catchment reaching Penarth, Barry, Caerphilly and Newport — a multi-site estate a single agreement can cover. The retail sector overview and the Cardiff page carry the rest.
