Mine Storage provides a storage solution with a unique, modular design, and reliable functionality. Our design is a fast response, closed loop system in abandoned underground mines. By using underground mines, we minimize the environmental impact, reduce construction costs, and utilize existing infrastructure such as grid connections. The availability of sites in the world is significant, as it is estimated that there are more than 500 000 abandoned mines with no current purpose.

We use modern modular technology from established providers adapted to meet the requirements of today’s electricity and balancing markets. Our solution is always designed based on how revenue will be generated, i.e. from electricity trade arbitrage and/ or ancillary services such as grid frequency control. Mine Storage is a suitable solution for both bulk storage and balancing services. For each mine storage plant, the operational model is developed to optimize the revenue based upon the conditions of the local market.
