Portugal: Hyperion's 24 MW solar plant in Abrantes has been feeding the grid since October

The photovoltaic plant built by Hyperion Renewables in the village of Arreciadas, in the municipality of Abrantes (Santarém district), is producing power for the grid. "It is connected to the electricity grid and has been in full operation since October 2026," an official company source said, according to the Lusa report published on 6 November by Notícias ao Minuto and mediotejo.net.

The figures. The plant has an installed capacity of 24 MW, up from the 18 MW announced in February 2026, and estimated output of more than 65 GWh a year, equivalent to the consumption of about 20,000 homes, according to the company. In February the estimate was more than 50 GWh and about 15,000 homes. The park covers 53 hectares and has around 35,000 solar panels.

The connection. Power is fed into the grid through the Olho de Boi substation in Alferrarede. In February, when it announced that panel installation was complete, the company expected production to start in the second quarter of 2026, once the grid connection line was finished. Construction was announced in May 2024; at that time, according to Lusa, the investment was put at about 19 million euros and commissioning was planned for early 2025.

The company. Hyperion Renewables, founded in 2006 and based in Lisbon, develops solar, wind and storage projects. It reports more than 770 MW of projects developed and more than 300 MW of assets in operation or under construction. In Abrantes, Hyperion II Renewables Services is also planning a data centre in the Alvega and Pego area with a 200 MVA grid connection; the municipal council gave a favourable opinion on the preliminary information request in May, and the project, still being licensed, is expected to start operating in 2029.
