Local Opposition Mounts Against Marine Pumped-Storage Projects in Southern Galicia
Two seawater pumped-storage hydroelectric projects are being planned for the Serra da Groba mountain range in southern Pontevedra, Galicia. Local social collectives and environmental groups have submitted approximately 50,000 allegations against the proposals. Project Controversy Both projects—Fonte das Mañas and Portocelo—are promoted by subsidiaries of Beltaine Renewable Energy, founded by the late Jesús Alonso. Critics allege the projects are being split into two separate entities to keep their capacity just under the 50 MW threshold (49.95 MW and 49.77 MW), thereby avoiding federal jurisdiction and joint cumulative environmental impact assessments. Technical documentation shows suspicious similarities between the two filings, including identical technical figures and site data, suggesting a lack of site-specific analysis. Risks and Viability Concerns The use of saltwater poses significant risks to local aquifers and potable water sources in Oia and O Rosal, with potential for saltwater intrusion and contamination. Critics point out that pumped-storage facilities do not generate new energy but store it; given the current lack of nearby wind or solar infrastructure to power these pumps, the projects' energy sustainability is in doubt. The municipality of Oia has formally expressed concerns that the impact on local groundwater and the potential need for significant blasting in rocky terrain could lead to irreversible environmental damage and uncontrollable risks to the local water supply.
