Energy Storage Systems: What They Are and How They Work

Energy storage systems offer many possibilities benefits for the electricity system and end users. First of all, they allow frequency and voltage to be regulated, maintaining the parameters of the power grid within the established limits and thus avoiding instability, overloads or power outages. At the same time, they enable modulate consumption depending on energy availability and costs, reducing demand peaks and increasing energy efficiency. In addition, they allow for autonomous and grid-independent consumption and production of electricity, increasing resilience and security.

Secondly, energy storage allows for economic savings, through energy arbitrage: buying electricity when the price is low and selling it when the price is high, taking advantage of electricity market fluctuations and optimizing profits.

In addition, energy storage facilitates the use of renewable energy sources: By compensating for the variability and irregularity of energy production from sources such as solar and wind, it ensures greater penetration and less dependence on fossil fuels.
