IN Brief:
- METLEN and Nala Renewables have signed sale and purchase agreements covering four UK solar projects with approximately 119MW of capacity.
- The Norfolk, Somerset and East Sussex sites are at ready-to-build or construction stages, with delivery planned in 2027–2028.
- Once operational, the portfolio is forecast to produce almost 131GWh annually, with revenue under corporate PPA and CfD arrangements.
METLEN has signed sale and purchase agreements with Nala Renewables covering four proposed UK solar farms with a combined capacity of approximately 119MW. The sites are in Norfolk, Somerset and East Sussex and are at ready-to-build or under-construction stages. Both companies confirmed the transaction on 10 November. The contracts therefore establish a route to new ownership of projects still being delivered, rather than a sale of four already operating generating stations.
The projects are expected to be constructed and handed over in phases during 2027 and 2028. METLEN says delivery of each asset will be complete upon the issue of its provisional acceptance certificate, providing a defined handover point in the construction programme. The companies have not disclosed the purchase price, the individual names and capacities of the four sites, or a timetable for the precise transfer of each special-purpose project company.
Nala forecasts annual production of almost 131GWh once all four parks are operational. Its equivalent-of-52,320-homes comparison uses assumed annual household consumption of 2,500kWh, rather than reflecting a direct supply contract with those households. Generation will vary with irradiance, module temperature, losses and plant availability; the export network may also impose constraints. The forecast is a portfolio-level expectation, not measured electricity already produced by the assets included in the agreements.
Ready-to-build and under-construction projects carry different completion obligations. The first status indicates material development work has been completed, but equipment procurement, electrical installation and grid energisation may still be ahead. For the sites where construction is under way, inverters, transformers, protection systems and collection cables will need to be installed and tested before power can be exported reliably. The companies have not broken down the four projects by maturity or identified which milestones each has reached.
At each location, the delivery process must coordinate photovoltaic modules, support structures, inverters, medium-voltage collection circuits, transformers and the interface with the relevant electricity distribution or transmission network. Inverters convert the direct current generated by the modules into alternating current compatible with the grid, while transformers adjust voltage for collection and export. Protection, monitoring and control equipment must then demonstrate safe operation within the applicable network code and connection agreement.
The 119MW aggregate rating does not reveal the planned AC export limit at each site, its inverter configuration or the voltage of its network connection. Those details influence electrical losses, compliance testing and how generating output will be controlled when network conditions change. METLEN has not identified equipment suppliers, the individual solar park names or detailed energisation dates. Engineering progress therefore needs to be judged through subsequent construction and acceptance milestones rather than the portfolio total alone.
Nala says the generating assets will earn revenue through a mix of contracted arrangements, including a corporate power purchase agreement and Contracts for Difference. A corporate PPA can give an electricity buyer and generator a negotiated structure for offtake or price management, while a CfD supports eligible low-carbon generation through a strike-price mechanism. The companies have not specified which individual projects benefit from each arrangement or disclosed prices, tenors or counterparties.
Under the agreements, METLEN expects each solar park to be delivered to Nala after issuance of its provisional acceptance certificate. That defined handover milestone puts completion and performance evidence at the centre of the transaction: contractors must establish that the plant and its relevant systems meet the agreed acceptance criteria. The companies have not disclosed the allocation of every construction risk or the financial consideration. An agreement to acquire assets ahead of completion is not the same as the transfer of commissioned generating capacity.
METLEN develops and builds renewable projects as part of an asset rotation model, transferring completed or maturing assets to long-term investors and using proceeds to support further development. It reports more than 70 UK renewable generation and storage projects delivered, with more than 20 progressing, spanning solar, batteries and hybrid schemes. Those are figures for the company’s wider UK activity, not equipment already delivered under Nala’s new four-project agreement. The transaction continues an established engineering and investment approach.
Nala, a London-headquartered renewables investor, is expanding into the UK through projects that will require continued engineering delivery before production begins. The companies have described the agreements as a possible foundation for later cooperation on solar and storage elsewhere in Europe, but have named no additional assets. Nala has not published a breakdown of the 119MW across the four counties and sites, or the expected cost and timing of any outstanding network works.
Delivery is scheduled in stages across 2027 and 2028. The next evidence of progress will be commencement of works at the ready-to-build sites, completion of electrical installation, grid connection, testing and provisional acceptance of the individual plants. Their annual 131GWh production forecast will remain prospective until the facilities operate. At present the confirmed outcome is a signed set of sale agreements under which METLEN is expected to complete and hand over four UK solar developments to Nala.
