Greenvolt Offloads 231-MW Spanish Wind-Solar Portfolio in €195m Sale Agreement

• Portugal’s Greenvolt will sell 145 MW of near-term wind-solar assets plus 86 MW of greenfield projects in Spain to Transiziona for up to €195 million.

Portuguese renewables group Greenvolt has agreed to dispose of a 231-MW mix of wind and solar projects in Spain for up to €195 million (USD 222 million), continuing the company’s strategy of recycling capital from large-scale developments. The buyer is Transiziona, an energy-transition platform owned by Swiss infrastructure investor White Summit Capital. 

What’s in the package?

• 145 MW forward sale – projects already at, or close to, ready-to-build status will be transferred once they reach commercial-operation date (COD).

• 86 MW greenfield pipeline – early-stage sites that Transiziona will take through permitting and construction.

The assets were developed through Greenvolt’s joint venture with Green Mind Ventures, which focuses on Iberian green-power opportunities. After closing, Greenvolt’s cumulative disposals in 2025 will reach roughly €530 million, including recent transactions in Poland worth €333 million.

Why it matters

• Capital rotation – Greenvolt aims to sell 70-80 % of its utility-scale projects at either ready-to-build or operating stage, ploughing proceeds into its 13.2-GW global pipeline across 18 countries. The firm hopes to advance 5.3 GW to ready-to-build status by end-2025.

• Market signal – Despite volatile power-price forecasts, institutional investors remain hungry for de-risked renewables in Spain, Europe’s fastest-growing utility-scale solar and onshore-wind market.

• Portfolio synergy – Transiziona gains diversified capacity that can slot into Spain’s existing grid corridors, improving the economics of co-located battery storage and corporate PPAs.

Next steps

Regulatory approvals are expected in the second half of 2025. Construction of the forward-sale projects should be finished by 2026, with the greenfield tranche staggered through 2027-2028. Upon commissioning, the combined portfolio could supply around 160,000 Spanish households and offset 220,000 tonnes of CO₂ a year.

Executive view

Greenvolt CEO João Manso Neto called the deal “another proof of our asset-rotation model,” adding that proceeds will shore up balance-sheet flexibility as the company targets more storage and hybrid projects. Transiziona’s managing partner Carlos Amorim said the purchase “cements our position as a long-term owner-operator of high-quality Iberian renewables.”

With Spain still eyeing 62 GW of additional wind and solar by 2030, Greenvolt’s latest exit shows how developer-to-investor hand-offs are shaping the Iberian energy landscape—and why well-timed sales can be as strategic as building turbines and panels.
