Trend in net load peak-valley difference amid growing VRE penetration (IMAGE)
Caption
The figure illustrates how rising variable renewable energy penetration changes the daily power supply structure and widens the peak-valley difference in net load. As wind and solar generation increase, non-VRE resources must balance larger fluctuations, creating growing demand for flexible resources such as energy storage, demand-side response, interregional transmission, and carefully designed capacity mechanisms.
