The aim of this research is to evaluate the role and potential of energy storage technologies in enhancing the energy security of the Republic of Moldova, particularly in the context of increasing renewable energy integration. As Moldova transitions toward a more sustainable energy mix, storage systems such as electrochemical batteries, pumped hydro, green hydrogen, and thermal storage become critical for balancing supply and demand, reducing import dependency, and ensuring grid stability.

The study incorporates a recent case from a European region where a sudden disconnection of large-scale renewable generation caused a major blackout, disrupting essential infrastructure and affecting millions of consumers. This example underscores the systemic risks associated with insufficient grid flexibility and the absence of robust storage capacities during periods of renewable intermittency.

Building on this analysis, the paper outlines strategic recommendations for Moldova, including investment in storage technologies, modernization of the national electricity grid, and the creation of a coherent regulatory framework to support innovation and resilience. The research concludes that energy storage is not merely a technical complement but a foundational element of national energy security and crisis preparedness.
