Dos Grados Buys 500 MW of Early-Stage Spanish Solar Projects

Dos Grados has agreed to buy three Spanish solar projects with a combined capacity of more than 500 MW from French developer Akuo. The deal was reported on 7-8 October 2026, and the sites sit in Castilla y León and Andalucía.

None of the three is ready to build. The projects are at an initial processing or early permitting stage, and neither party has disclosed a price.

Without a valuation, the deal’s interest lies in its strategy rather than its numbers. The buyer runs a mature 600 MW portfolio, so taking on projects this early is a deliberate choice.

Why would a 600 MW investor buy projects that are not yet ready to build?

At first glance, paying for unbuilt and unpermitted capacity looks like an odd move for an investor already running a working portfolio. Dos Grados was founded in 2019 and operates 600 MW across solar, wind and storage in Spain and Portugal. This purchase almost doubles its footprint on paper.

Renewables Now first reported the deal, and Europa Press and Forbes España later confirmed it. Coverage framed the purchase as a new step in consolidating the company’s Iberian strategy.

Luis Palacios Castañeda, CEO and founder of Dos Grados, said the deal fits the company’s growth strategy in Spain, expands it into two key regions and aims to combine renewable generation with other land uses. He added that Akuo brings expertise in territorial integration and innovations such as agrivoltaics.

The following details remain undisclosed:

• Price or valuation
• Project names
• MW size of each project
• Grid-connection status
• Closing conditions and timetable
• Financial or legal advisers

What each side gets

For Akuo, the sale recycles capital and passes on the cost and risk of taking the projects through permitting and financing. It also converts work already done on early grid and permitting steps into cash.

The deal fits wider solar investment trends in 2026, as capital shifts from fossil fuel cycles toward energy infrastructure and developers recycle assets to fund new pipelines.

Dos Grados gains land and potential grid access in high-irradiation regions, which means areas that receive strong sunlight. It also gains the freedom to shape each project’s design before final permits are issued.

Seen this way, the purchase looks like positioning rather than a gamble. Early buying secures scarce grid and land positions before the ready-to-build market prices them in. The missing terms, however, mean you cannot yet test whether the value case holds.

Where does early-stage Spanish solar sit in a market heading for 76 GW?

The growth figures support that positioning. According to Red Eléctrica de España (REE), Spain had almost 50 GW of solar installed at 31 December 2025. Lower figures of around 33 GW appear in some reporting, but they are outdated or use a different definition.

Spain’s national energy and climate plan, the PNIEC, was approved in September 2024. It targets about 76 GW of solar by 2030, including 19 GW of self-consumption, alongside 22.5 GW of storage.

Full comparable deals are scarce. The closest found was Masdar’s agreement with Endesa in July 2024 for 49.99% of a 2.5 GW portfolio, but its geographic focus and valuation were not specified. Early-stage prices are usually kept confidential, and no quantified grid-queue figures were found.

Risks that come with the discount

• Permitting: environmental assessments and regional approvals can be slow and subject to changing criteria.
• Grid-right forfeiture: tighter milestone rules mean rights can be lost if a project falls behind schedule.
• Opposition: community and NGO resistance can lead to legal challenges or outright rejection.
• Merchant prices: cannibalisation, where heavy solar output depresses daytime power prices, weakens revenue for projects that sell power at market rates.
• Curtailment: congested grids can force plants to cut output.

An April 2025 ESS News analysis argued that, without pumped hydro, Spain should install no more than 50 GW of solar. That is one view rather than settled fact. Still, it shows where your risk concentrates: the gap to 76 GW rewards pipeline holders, but projects selling at market prices without storage or long-term supply contracts face the most pressure on returns.

Projects selling at market prices without storage face the most pressure, though Spain’s new capacity market now places generation, batteries and demand-side resources in one remuneration frame, which could shift the return profile for hybrid designs.

How does agrivoltaics change the case for these Spanish solar projects?

Palacios Castañeda’s remark about other land uses is easy to skip past. It deserves more attention.

Agrivoltaics means combining solar panels with farming on the same land. Akuo promotes the approach internationally, and Spanish policy has moved behind it. Agrivoltaics has been eligible for EU Common Agricultural Policy (CAP) funding since 2025, and Spain launched a national map of agrivoltaic projects in July 2026, according to PV Magazine.

Industry body UNEF has long argued that sharing land benefits with farmers strengthens social licence, meaning local acceptance of a project. The vineyards, horticulture and pasture of Castilla y León and Andalucía suit elevated or widely spaced panel layouts.

Several practical hurdles remain:

• Unclear land classification and tax treatment
• Slow coordination between regional agricultural and environmental authorities
• The need to prove long-term agronomic outcomes, meaning crop and farm results, to farmers and regulators

What is confirmed, and what is not

No agrivoltaic design has been confirmed for these three projects, and no named Akuo agrivoltaic projects in Spain have been publicly detailed. Treat the land-use angle as a possible way to reduce permitting and acceptance risk, and as part of the buyer’s bet, rather than a confirmed feature of the assets.

Investors exploring how dual land use performs at scale can read our deep-dive into Italy’s largest agrivoltaic plant, which shows how utility-scale panels coexist with active farmland.

What this deal confirms, and what remains unanswered

The transaction confirms that long-term capital is willing to take pre-construction positions in Spain’s solar pipeline. Price, grid status and design remain unknown, so the deal’s true value cannot yet be judged.

If you are tracking Iberian renewables, three developments will be worth watching:

1. Disclosure of closing terms and each project’s grid-connection status
2. Any confirmation of agrivoltaic or storage design
3. Whether more early-stage portfolio trades follow

Grid status matters most. It is the clearest signal of whether these projects are likely to reach construction.
