Project Overview of the Solar Energy Park
Hunosa plans to redevelop the Nicolasa coal mine in Asturias, Spain, into the San Nicolás Energy Park. This initiative represents a shift from coal to renewable energy, providing a new role for the former mine.
Investment Details for the Solar Energy Park
The redevelopment will involve an investment of approximately €24 million as part of Hunosa’s broader €110 million investment plan, which is set to run through 2028. This substantial commitment is aimed at facilitating the region’s energy transition.
Planned Capacity and Technologies of the Solar Energy Park
The San Nicolás Energy Park aims for a capacity exceeding 50 MW, with potential expansion to nearly 100 MW once final studies are completed. The project will incorporate multiple technologies, including a photovoltaic solar plant located on the mine’s spoil heap, a reversible pumped-hydropower system utilizing underground mine workings, and a surface hydropower project.
Expected Energy Output from the Solar Energy Park
Overall, the project is expected to generate enough electricity to power approximately 30,000 homes, bolstering renewable energy supply in Asturias.
Significance of the Solar Energy Park for Asturias
The redevelopment is particularly significant as it involves repurposing the Nicolasa mine, described as the last Hunosa shaft for coal extraction. This aligns with regional efforts to transition towards cleaner energy sources.
