Swedish company Sustainable Energy Solutions Sweden Holding AB (SENS) has announced plans to transform an abandoned mine in Spain into a pumped hydroelectric storage plant , marking its entry into the Spanish energy market.
SENS advances in energy storage projects with new partners
Through a statement, SENS revealed that it had signed a letter of intent with an undisclosed energy operator, highlighting their joint commitment to developing sustainable energy storage solutions.
SENS has captured global interest, attracting landowners and mining companies interested in converting unused spaces into underground hydroelectric storage facilities. These facilities are essential to support long-term energy storage and facilitate the transition to cleaner energy .
Feasibility study to transform mines into energy plants
The next step is to carry out a feasibility study that determines the viability of the project, analyzing commercial, technical, financial and legal factors. This study will allow SENS and its partners to decide on the future implementation of the project. Preliminary site visits have already been carried out with SENS personnel, and the feasibility study is scheduled to begin immediately.
The conversion of old mines into pumped hydroelectric plants has become a growing trend due to their lower environmental impact and initial costs compared to the construction of new facilities. This method works like a gigantic battery that uses water and gravity to generate electricity. During periods of low energy demand, water is pumped to an elevated reservoir and during peak demand, it is released downwards past turbines that produce electricity, continuously recycling the water in a closed process.
Delays in the national storage project
At the national level, the country has faced delays in the implementation of a capacity mechanism that encourages storage projects, such as batteries and pumped hydro, the process of which began two years ago and is currently stalled in Brussels. The country’s reliance on technologies such as gas combined cycles, pumped hydro, batteries, and thermal or chemical storage is crucial to supporting renewable energy growth in the coming years.
The initiative of SENS not only highlights innovation in the use of existing structures for new energy applications, but also underlines the importance of international collaborations in the development of sustainable infrastructures. As projects like this take shape, they could serve as role models for the integration of renewable technologies and energy storage in other parts of the world, demonstrating how the adaptive reuse of industrial sites can play a crucial role in the global green economy.
SENS and its partners are evaluating the feasibility of converting an abandoned mine in Spain into a pumped hydroelectric storage plant, using technology that minimizes environmental impact and upfront costs.
