Solar Power Purchase Agreements in Cardiff

Indicative 2026 tariffs for Cardiff sites range 10-18 p/kWh year 1 depending on system size, off-taker covenant, term length and DNO context. Larger systems (500kWp+) with strong covenants on 25-year contracts can achieve the lower end of the range. The Cardiff Council has a 2030 net-zero target which supports business demand for PPAs.

In Cardiff the most active PPA cohorts are typically manufacturing, logistics, hotels, schools and NHS Trusts. Named industrial estates including Cardiff Bay Business Park, Wentloog Industrial Estate, Capital Business Park are particularly suited to roof-mounted PPAs.

DNO context — specifically G99 connection availability and export capacity — drives the build cost (and hence tariff) of any PPA-funded system. For Cardiff, ground capacity is generally workable but the G99 application alone takes 6-12 weeks. Larger systems (250kWp+) often require additional studies.

From first call to commissioning typically 6-12 months. Indicative tariff in 2-4 weeks; site survey + heads-of-terms in 4-8 weeks; full contract in 8-12 weeks; build in 6-16 weeks. Site complexity, planning consent and DNO connection drive variations.

Sites within ~30 miles of Cardiff typically draw on the same provider network. For multi-site portfolios across neighbouring towns (Penarth, Caerphilly, Barry, etc.), a sleeved-PPA or corporate-PPA structure aggregates the kWh more efficiently than separate on-site contracts.
