Hyperion Renewables announced this Friday, February 27, the completion of the installation of 35 thousand solar panels at the photovoltaic plant in Arreciadas, Abrantes, and plans to start energy production in the second quarter of 2026, after connection to the electricity grid.
In information sent to Lusa, a company source indicated that, despite the park being structurally completed in Abrantes, in the Santarém district, the infrastructure is still awaiting completion of the grid connection line, a necessary condition for it to enter into operation.
“The photovoltaic panels and the park’s main structures are already installed. The project is progressing as planned and, at this moment, the focus is on building the connection line to the electricity grid, which is a complex and detailed process”, declared an official source from the company, pointing to the end of April as the scheduled date for entry into operation.
The project, whose construction was announced in May 2024, is installed in an area of 53 hectares in the village of Arreciadas, in the Union of Parishes of São Miguel do Rio Torto and Rossio south of the Tagus, and will have an installed capacity of 18 megawatts (MW), with estimated production of more than 50 gigawatt-hours (GWh) per year – enough for the average annual consumption of around 15 thousand homes.
As part of a protocol with the Abrantes City Council, signed in February 2025, Hyperion supports the Dem.Care.Abt project, aimed at 128 people with dementia and their informal caregivers, also financed by the Portugal Social Innovation fund.
The initiative includes training actions and innovative methodologies to support the community.
Other commitments set out in the protocol continue to be developed, such as educational activities, study visits to the center and the creation of an educational route in the surrounding area, with informative signage on the operation and impact of the infrastructure.
The injection point from the plant to the grid will be at the Olho de Boi substation, in Alferrarede.
