Valley filling involves utilizing energy storage to capture low-cost electricity during off-peak hours and using it during periods of higher demand. This strategy optimizes energy costs by taking advantage of time-of-use (TOU) pricing models where electricity prices vary throughout the day. [pdf]
[FAQS about What does valley filling of energy storage power stations mean ]
Grid energy storage involves capturing excess electricity produced at times when supply exceeds demand, to store and discharge later when demand exceeds supply. It provides a way to store surplus energy and use it later when needed to balance supply and demand on the electrical grid. [pdf]
