IN Brief:
- Enviromena has energised the 10MWp Rhigos Road solar farm near Aberdare in South Wales.
- The project uses a Class A licence-exempt supply arrangement through a PPA with Evolve Energy.
- The site includes more than 14,000 JA Solar bifacial modules and is expected to generate about 10,600MWh annually.
Enviromena has energised the 10MWp Rhigos Road solar farm near Aberdare in South Wales, using a direct electricity supply arrangement designed to serve business customers outside a conventional wholesale supply model.
The project is backed by a Class A licence-exempt supply arrangement through a power purchase agreement with Evolve Energy. Electricity generated at Rhigos Road can be supplied directly to businesses through Evolve Energy, creating a structure that avoids certain charges and levies normally associated with conventional supply arrangements.
More than 14,000 bifacial modules from JA Solar have been installed at the site. Annual generation is expected to reach around 10,600MWh, with more than 1,850 tonnes of CO₂ emissions avoided each year. Enviromena will own and operate the asset through its in-house operations, maintenance, and asset management teams.
Direct-supply models are gaining traction as businesses look for clean electricity procurement structures with stronger cost control and a clearer link to physical generation. Traditional corporate PPAs can still leave buyers exposed to wholesale market structures, network charges, imbalance costs, and settlement complexity. Licence-exempt supply offers another route where project location, regulatory conditions, and offtake demand can be aligned.
Rhigos Road also reflects a wider change in UK solar development. Ground-mounted solar farms are no longer judged only by installed megawatts. Their commercial value increasingly depends on grid connection, route to market, offtake structure, and the ability to operate through periods of price volatility or network constraint.
A well-sited solar asset with a direct supply agreement can have a different risk profile from a merchant project exposed more heavily to wholesale market fluctuations. The generation technology may be familiar, but the commercial and regulatory structure changes how value is captured from the electricity produced.
Private-wire and direct-supply models are becoming more visible across industrial and commercial energy users. Sonaura’s proposed private-wire solar supply to Bentley Motors follows the same direction from a manufacturing-site perspective, with generation and offtake arranged around a more direct relationship than standard electricity retail supply. Rhigos Road uses a different structure, but both projects show business energy procurement moving beyond generic tariffs and renewable certificates.
The electrical design requirements for projects of this type remain substantial. Metering, settlement, protection, grid compliance, inverter performance, communications, export controls, and asset monitoring all affect how the system operates. Bifacial modules can improve yield where site conditions support rear-side generation, although performance still depends on ground treatment, array spacing, cleaning, inverter configuration, and operational availability.
UK solar deployment continues to expand across domestic, commercial, public-sector, and utility-scale settings. The sector passing two million installations marked a significant point in market maturity, while hybrid projects such as European Energy’s Cornwall solar and battery build show how generation and storage are increasingly being developed together. Solar is becoming a mainstream electrical infrastructure package rather than a niche generation technology.
The next phase of growth will be shaped by connection availability and route-to-market design. Direct supply can improve the economics of some projects, but it requires suitable counterparties, regulatory clarity, robust metering, and carefully structured agreements. Storage may also become more relevant for future direct-supply schemes where generation profiles need to be matched more closely with customer demand.
Rhigos Road adds a practical example of a UK solar project moving from development into operation with a tailored commercial structure. Its output is modest compared with transmission-scale generation, but its supply model points toward a more flexible electricity market, where generation, offtake, and regulation increasingly have to be engineered together.
