FREQUENTLY ASKED QUESTIONS

WHAT IMPACT DOES ENERGY STORAGE HAVE ON THE GRID?

Energy storage systems play a fundamental role in enhancing grid stability and reliability. They enable the integration of intermittent renewable energy sources, such as wind and solar, by storing excess energy generated during peak production for later use when demand is high. This capability not only helps to balance supply and demand but also mitigates the risk of outages and disruptions. Furthermore, energy storage systems provide valuable ancillary services, such as frequency regulation, which ensures the grid operates within its operational parameters.

Beyond these operational benefits, the deployment of energy storage can also lead to significant cost savings for utilities and consumers alike. By enabling peak shaving, energy storage reduces peak demand charges, ultimately resulting in lower electricity bills. The cumulative impact of increased energy storage penetration into the grid bolsters the effort towards a more reliable, resilient power system while simultaneously enhancing the overall sustainability of energy infrastructure.

WHAT ARE THE MAIN CHALLENGES FACING THE ENERGY STORAGE MARKET?

Despite the rapid growth of energy storage technologies, several challenges persist that may hinder their widespread adoption.
