Solar PPA for offices & workplaces in Cardiff

One Planet Cardiff and the workplace roof

Cardiff's climate framework, One Planet Cardiff, sets a 2030 net-zero goal, and the council has made Cardiff Bay a focus for sustainable development. Offices around the Bay and Atlantic Wharf, together with the commercial floorspace of the CF10 and CF24 core, sit on roofs that suit a 50–500kWp array. The surrounding market — Penarth, Barry, Caerphilly and neighbouring Newport — falls within the same regional catchment.

The daytime match that makes it pay

What makes an office a strong solar host is the shape of its demand: heaviest through the working week and daylight hours, exactly when a roof array produces. High self-consumption follows, and a PPA can therefore price power at 13–18 p/kWh, below grid. Against Cardiff's average commercial spend of roughly £45,000 a year, a well-sized system returns £8k–£90k in annual savings.

Welsh funding routes and the grid

The Welsh Government Energy Service is open to qualifying Welsh businesses, and Business Wales loans via the Development Bank of Wales are a typical funding route to consider alongside a PPA. Distribution across Cardiff and out toward Pontypridd and Barry is managed by National Grid Electricity Distribution, whose Welsh network sets connection and export limits for any new generation.

Solar without the capital call

A power purchase agreement means the developer funds, installs, owns and maintains the panels; the occupier simply pays for the electricity produced at an agreed, discounted rate. For Cardiff's blend of owned and leased office stock, that removes the usual budget obstacle.
