IN Brief:
- Gresham House and Amegni Renewables have reached financial close on Carno 3.
- The 45MW North Wales project has secured £80m from Santander and Rabobank.
- Construction is underway, with commissioning targeted for autumn 2027.
Gresham House and Amegni Renewables have reached financial close on the 45MW Carno 3 wind farm in North Wales, securing an £80m project finance facility from Santander and Rabobank.
The project is being developed through Carno 3 LLP, a joint venture established by Gresham House and Amegni Renewables. Construction is now underway and is expected to continue through 2026, with commissioning targeted for autumn 2027.
Carno 3 is expected to become one of the largest onshore wind farms in Wales once operational. The scheme is forecast to generate enough renewable electricity to meet the annual needs of around 46,000 homes and avoid approximately 65,000 tonnes of carbon dioxide emissions each year. Vestas has been selected as turbine supplier, while Jones Bros will serve as balance-of-plant contractor.
The project extends an established wind cluster in the Carno area. Gresham House already provides asset management services for the neighbouring Carno 1 and Carno 2 wind farms, giving the new project a close operational relationship with existing renewable generation assets in the region.
Financial close gives the project its construction capital after lender due diligence on technical, legal, environmental, and commercial factors. For onshore wind, that stage requires alignment across turbine procurement, grid connection works, civil engineering, balance-of-plant packages, community obligations, construction logistics, and commissioning schedules.
Carno 3’s move into construction adds to a stronger Welsh onshore wind cycle. Twyn Hywel in Caerphilly has also moved forward with major financing, showing that consented Welsh schemes are now reaching delivery after a slower period for UK onshore wind. That creates a more active pipeline for turbine suppliers, civil contractors, electrical contractors, grid specialists, and operational service providers.
The technical work around Carno 3 will centre on bringing generation from turbine foundations through internal electrical networks and into the grid connection system. Balance-of-plant delivery will include access routes, crane pads, foundations, cable trenches, substation interfaces, protection systems, earthing, communications, and commissioning. The quality of those packages will shape operational availability across the project’s working life.
Wales offers strong wind resource, but project delivery can be demanding. Rural locations, terrain, road access, ecological commitments, local consultation, and grid connection constraints all influence construction sequencing. Onshore wind may be a mature technology, but each site still requires careful engineering integration between civil works, electrical systems, turbine logistics, and grid compliance.
The financing also arrives as onshore wind regains strategic attention in the UK’s clean power planning. Offshore wind remains the larger headline sector, but onshore projects can often be built faster where consent and grid connection are in place. They also provide geographical diversity and can support regional supply chains, provided local confidence is maintained through construction and operation.
European onshore wind activity is increasing as developers seek bankable revenue structures, grid access, turbine availability, and construction partners able to manage more complex permitting and logistics requirements. Vestas turbine orders in Bulgaria show similar demand returning in other markets, with established technology being deployed against a more constrained grid and supply-chain backdrop.
Carno 3’s lender group also reflects the infrastructure character of modern renewables. Santander and Rabobank are providing long-term project finance against a scheme with proven technology and an established regional context. Debt-backed delivery requires clear risk allocation between developers, contractors, equipment suppliers, and revenue assumptions.
The project’s relationship with nearby Carno assets may support operational learning around wind conditions, access, maintenance, community engagement, and network operation. Existing regional experience does not remove construction risk, but it gives the new project a clearer operating context than a greenfield site in an untested area.
Carno 3 now has the capital structure needed to proceed. The next stage will depend on construction execution, grid commissioning, and the ability to bring another Welsh onshore wind asset into operation by autumn 2027.
