The Coed-Ely Solar Farm is the latest project to contribute towards Rhondda Cynon Taff (RCT) Council’s wider plan to achieve carbon neutrality by 2030. The site features an impressive 6 MW ground-mounted solar array with over 9,400 high-efficiency panels, generating enough clean energy to power 1800 homes annually by exporting 5MW to the grid, also supporting critical healthcare services by exporting 1MW of clean electricity directly to the Royal Glamorgan Hospital enhancing local resilience.



Commissioned by RCT Council and developed by Vital Energi, Nuvolt was appointed as a specialist subcontractor to deliver key electrical infrastructure, ensuring safe, reliable, and efficient power distribution across the site. The project demonstrates how collaboration between public and private partners can transform former industrial land into a large-scale renewable energy asset with tangible environmental and community benefits.

Powering Local Communities and Public Services

Built on an 84-acre brownfield site once home to the Coed-Ely Colliery, the solar farm delivers clean energy while supporting Wales’s transition to more sustainable electricity generation. Beyond powering the hospital and contributing to the National Grid, the project has created economic value through local employment, apprenticeships, and partnerships with regional contractors and suppliers

Funded through a collaboration between Rhondda Cynon Taf County Borough Council, the Welsh Government, and the UK Government’s Shared Prosperity Fund, Coed-Ely Solar Farm is a clear example of how coordinated investment in renewables can drive environmental, social, and economic benefits, enhancing local energy security and supporting long-term sustainability goals.

Our Role

We were responsible for delivering several critical elements of the project’s electrical infrastructure, ensuring safe, reliable, and efficient power across the site. Key contributions included:

• High Voltage (HV) Installation: Delivered complex HV systems to connect the solar array to the substation, enabling safe and efficient transmission of power.

• AC Supplies: Installed AC connections from the transformer to the LV switchboard, ensuring seamless distribution of electricity to both the National Grid and the hospital.

• Private Wire Network Integration: Integrated the dedicated private wire network, delivering reliable power directly to the Royal Glamorgan Hospital.

• Solar Inverters: Connected the inverters that convert DC from the solar panels into usable AC power for the site and grid

• Testing and Commissioning: Completed comprehensive testing and commissioning to guarantee safe, efficient, and reliable operation across the entire installation.

Through these works, Nuvolt played a key role in translating the project’s vision into a functional, high-performance energy system.
